Odds & Ends 46: Shop Update and Viewer Mail

[@RandallMoore1955]

Hi Keith, I have to say your shop will be a pleasure for you to work in, Lots of light not to mention the sun light I see starting to come in through the windows outstanding. Thank you for showing and taking you time to do so, STAY SAFE.

[@VintageMachinery]

+Randall Moore Thank you Randall!

[@roylucas1027]

You certainly deserve your success. Thank you.

[@VintageMachinery]

+Roy Lucas Thank you Roy!

[@elsdp-4560]

THANK YOU...for sharing. I really like the shop, the ceiling lights in the center look great.

[@VintageMachinery]

+ELSDP-45 Thank you!

[@bsideadventures2180]

Keith sometimes life is tuff. Watching your videos eases the mind. thank you sir

[@clubdjmarcus]

your machine shop really is something to envy; the size, the looks, it's content, the woodland location...every mans dream of a backyard workshop. Really great job. Can't wait to see it finished...

[@VintageMachinery]

+mister marcus Thank you!

[@ksingleton101]

11:30 PM Friday, 60,133 subscribers, Congrats! The spay insulation that are on the market these days are awesome. I've been out of the Construction Field, Plastering for almost 10 years now but the spray insulation's we used on Structural Steel was incredible. Now day's its like spray painting and then measuring the final product after it expands for proper thickness. It shouldn't take more then 8 hours to complete the entirety of your shop, start to cleanup. Good luck! Can't wait to see the shop being used for what you intended it for.

[@VintageMachinery]

+K Singleton I have not had time to track down somebody to give me a quote on the insulation yet - I just hope I can afford it!

[@robertmccracken72]

The shop looks great. I really like the lights that you re-purposed, they look great. I use the LED floods in my barn and they work great. The only thing is they last so long I have to get up and clean them a couple of times a year because they get so dusty. A small price to pay!!! The spray foam is a really good idea, we use it up here in the north all the time, and it insulates and gives you a vapor barrier all in one. Great work!!!

[@ebones6957]

I love your shop...I had similar plans but waited too long, now I’m in the downward end of life. It nice to see someone else realizing their dream. You have really done your homework on acquiring 3 phase power. I am in total agreement with your thought process. I’m sure rotary converters are more easily obtained on the surplus market rather than used VFD’s. Your dissertation was excellent concerning the pro’s and cons. I have been involved with industrial facilities where 3 phase power wasn’t available; VFD’s were the only option and cost was not an issue. With new installation of VFD’s the motors should be “Inverter Rated”. This means they have extra wire insulation, and designed to work at different line frequencies. When run at slower speeds internal fan/cooling must also be considered, all, increase cost. A “standard” 3 phase motor will definitely run on a VFD, but one must consider all things which reduce efficiency. Using a rotor converter does reduce horsepower but usually not a problem with machine tools, you just take a lighter cut. Wiring for 3 phase and then using a centrally located RPC is a good idea because if 3 phase service becomes available your all set. Possibly in the future you might find a used “gen-set” ( engine driven 3 phase alternator) converted to propane or natural gas. You could use one to produce your own 3 phase power. You could add a small transformer on one leg for single phase. My background is electrical/electronics but I dabble with machine tools. My shop is in my basement, I have a 6”x 30” lathe and two milling machines. I disassembled them and winched them into the basement in pieces, and reassembled years ago. When I pass the new home owners will have a treat, LOL. Anyway, thanks for sharing, I certainly am getting a lot of enjoyment from your channel. I wish you were my neighbor!

[@w056007568]

What a useful and interestingly informative video. Many thanks for your reasoned explanation of your plans for powering your various machines.

[@skinny6523]

Good looking pup you have there Keith. The shop is coming along great, looking forward to working on projects out there real soon..........Kevin

[@VintageMachinery]

+skinny6523 Thanks Kevin!

[@williamwazere]

What a beautiful workshop in the making. I hope to get there myself one day! It's the dream to create, from the ground up, your own space like that. In the mean time I'll do what I can, where I am, with what I've got. Looking forward to more projects and knowledge Keith, keep 'er lit.

[@VintageMachinery]

+zero_sum Nothing wrong with making do with what you have. I have been doing that for 20+ years. But it sure is nice to see your dreams coming true!

[@davidcashin9194]

Hi Keith Shop is looking good it's going to be awesome when you get all your machines in cannot wait to see it up and running very jealous would so love to have a shop like that congratulations on the subscription mile stone. Cheers Dave

[@VintageMachinery]

+David Cashin Thanks Dave!

[@jan-roarbernhardsen7626]

You work hard , and like Roy say you really deserve your sucess and to soon be ready to work in the new shop. Have a nice weekend

[@VintageMachinery]

+Jan-Roar Bernhardsen Thank you!

[@tombellus8986]

I really like those lights you built they fit in nicely with the rustic style of your shop.Enjoyed ----- thanks

[@VintageMachinery]

+Tom Bellus Thanks Tom - that was the plan!!!

[@bcbloc02]

Shop is looking great, nice to be able to see in there! I was worried that the spray foam on the wood would cause rot issues by trapping moisture. I plan to put my rotary phase converter up in the attic in the barn/shop so I don't have to listen too it. I currently run a 30hp idler setup and it struggles starting the 25hp in the Cincinnati. Big congrats on the subs! I will probably have my shop done before I ever even get to 5K and that allows a few years. lol If I was you I would just run both RPC's all the time for convenience. The power drawn by an idler once started is minimal. My 30hp idler costs less than a 25cent an hour to run when running my 10hp lathe, with no load demand so you might be looking at like a nickle an hour difference between running one or 2 phase converters.

[@pierresgarage2687]

+bcbloc02 I have access to a power meter if needed, out of curiosity, I tested the 20HP idler on my phase converter just to find out how much it draws when idling, just using a regular amp clamp, it reads about 27 amps on 240 volts, this would mean 6480 watts, but when reading with a real power meter it reads about 1100 watts on idle due to the phase shift caused by the inductive charge of the idler, as when you draw more power the phase aligns closer to zero and the real power reads closer to reality... ;) I'd love 3 phase power, since it's available, but the installation would be at least over 8k$... :(

[@VintageMachinery]

+bcbloc02 A 30 HP RPC - I love it! I keep debating what I want to do. I have had someone offer a 15HP idler motor and am now considering just building a big one....

[@bcbloc02]

Keith Rucker - VintageMachinery.org You should watch my latest video for big RPC news!

[@csk1022]

I just retired after 38 years from Lincoln. Glad to see they sent some things. It’s a great place to work and their products are number 1 all around. Looking forward to see what you do with them. Jeff K. in Mentor, Ohio

[@VintageMachinery]

+csk1022 Thanks Jeff - I am looking forward to getting some welders here in my new shop in the future!

[@csk1022]

+Keith Rucker - VintageMachinery.org Keith, Thanks for the reply. I’ve been watching your videos for about a year now and enjoy the laid back explanations of what you are doing. What you are doing with them is very valuable for the younger generation to inspire them to do something other the push gaming buttons. I’ve been involved in manufacturing for 40 years and am always eager to learn new little tricks of the trade. Thanks again, Jeff Klein, Mentor, Ohio.

[@fibrodad1354]

Congratulations, been watching your shows along time now, and you finally have your dream shop. Looking forward to so work and restorations, love all but the safe was my fave!

[@VintageMachinery]

+JRushPixel Well, I have a building, the "shop" still has a ways to go before it is all finished..... I have plenty of restoration projects to get done once the shop is a little farther along....

[@harveysmith100]

With spray foam insulation and LED lights you are going to be so happy in that shop. It is going to be lovely and cool. Hats off to you, with the high ceiling and exhaust fan you have a great design.

[@VintageMachinery]

+Harvey Smith Thanks - I sure hope it does what I want it to do for me!

[@JackHoying]

The shop is looking great. As others have probably done, I have my RPC idler located high in my attic and mounted with vibration isolation in mind. It helps a lot with the drone that you normally have with a RPC. You can even build a "doghouse" outside your shop to hold the idlers, which would all but eliminate the noise.Congrats with the 60,000+ viewers!

[@VintageMachinery]

+Jack Hoying I am considering putting it out side.

[@JackHoying]

Especially in your situation with making videos!

[@thomasrotella9248]

Keith, love your channel and your shop is coming along nicely. I have a suggestion for you for sealing your concrete floor. I have been in the construction industry for many years and the only "sealer" that I recommend is Ashford Formula. It is inexpensive, water based, easy to apply, and will last forever, plus you can walk on it right away. Your typical spray on sealers will wear off in your heavy traffic areas and will have to be replaced. The Ashford penetrates deep into the concrete and hardens from the inside out.

[@VintageMachinery]

+Thomas Rotella A bit too late - I actually sealed the first half of the shop earlier this week before heading out of town for a few days. I hope to get the other half done this weekend....

[@larryfisher7056]

Thanks, another great episode in the shop build. Very interesting info on 3 phase options..

[@mrfrog3350]

Keep pluggin' along Keith! The cash flow/progress factor is a problem for lots of us.The shop looks great!

[@RoelTyros]

Hello Keith, Great to see you again after longer time but no problem that you were to busy with other things like work and the shop. Very nice that you put a shop update in the odd&ends en good to see that you now have electricity in the shop. You're explanation about 3 phase was also interesting and I also learned today something about 3 phase and cars. Next week we get an Honda hybrid care and I didn't now that they also use a 3 phase AC 20 HP motor. Honda uses a battery pack at 144 volts and the DC power out of that pack gets converted to AC and drives that electro motor. That motor assists the petrol engine and also acts as an generator to charge the battery pack. Anyway, still strange that it is so difficult in America to get 3 phase from the electrics company. So as I told you, here in the Netherlands we have in every home 3 phases but normally they connect only 1 phase. But for electrical stoves or ovens than you can ask the company to connect the other 2 phases. Looking forward to the next video and I will wish you much succes with all the work in the shop. Many greetings from Roel !

[@VintageMachinery]

+RoelTyros Yeah, the lack of three phase in homes here is somewhat of a mystery to me. I think that it goes back to the 1930's when people were first wiring up homes for electricity and about the only thing they were hooking up was lights. Back in those days, nobody could imagine the need for three phase power in a home to run things like air conditioners, refrigerators, etc. So, they started only hooking up one or two legs. In retrospect, it was a bad decision but now that the precedence is set, it is hard to get them to change. Oh well - that is just the way it is. Interestingly, my father in law has a house built back in the early 1970s that had three phase ran into for whatever reason. The power company does not like it one bit and keeps trying to get him to change it but they cannot force him to do so. It is a larger house and has I think three large air conditioners - all of which are three phase powered. It saves him a ton of money on his power bill because the three phase units are so much more efficient. Perhaps that is why the power companies don't want us to have three phase in the house - they would loose a lot of revenue from the power savings.....

[@rolliekelly6783]

Keith you have 2 new fans. During our family gathering last weekend, Andrew (son in law #2) asked about how sawmills operate. Quick as a dead cat, I had your Deloach video on the tv. Both of my sons in law were totally enthralled and now want to visit the museum. Before the night was over, they were instigating a trip. Glad to see so much progress on the shop, Rollie

[@VintageMachinery]

+Rollie Kelly I hope that they make the trip down. If they want to see the sawmill operate, they might want to coordinate with me as the museum does not run it every day. But you can run that video any time you like!!!

+Steve S Thanks Steve!

[@vajake1]

Congratulations on 60,077 subscribers! That was a lot of information! I had no idea that multiple rotary phase converters could be ganged in series to provide three phase power to larger horse power motors. I have been running a rotary phase converter for years in my garage shop and I dislike the loud "motor running sound" that it makes. I have been thinking of going to VFD just to make it more quiet in the shop. Thanks for all that you do. I always learn something new from your videos!

[@jameskerns717]

+vajake1 I would assume that they would be hooked in parallel, but I would be curious about how you get the two machines to run in phase.

[@bcbloc02]

+James Kerns They are both powered by the same line voltage so their phases have to be the same.

[@duobob]

+vajake1 I understand that you can also turn on other three phase machines in the shop to achieve the same thing as adding another RPC. The machines that are idling act as RPC's for the network. I don't know how that effects wire sizing, etc....

[@bcbloc02]

***** My experience has shown that adding machines doesn't seem to do much for how much I can run. I think one major difference is that the generated leg on a RPC is balanced using capacitors to achieve a matched load, which is something you don't get from just another machine running. I actually find that if I run a bunch of machines at the same time that well exceed the RPC idler output then my voltage balances tend to go in the toilet.

[@VintageMachinery]

+vajake1 Responding to several comments in this thread. As for keeping the two RPC in phase with one another - this is very important to do. Each leg should be in phase with the leg that you are adding it to when combining RPC's. If you do not do this, it can cause serious issues, damage the electronics in your RPC's and even case a fire. As for turning on another motor in the shop for added power - this is somewhat of a myth. It does help to have extra motors idling in the shop to help start a big motor, but it will not really add extra horse power to the grid.

[@mrbluenun]

Hi, And thanks for the video upload, especially interested in your new shop uploaded thank you. It looks so much larger than it first did to me. I hope everything goes really well there especially with the new machine layouts and they go without too many drop-ages! ;=) I know it did not exactly come as a free gift, but I still have to say how envious I am with the room there is, but no doubt it is designed for the larger things you may have to work on and it will be nice not having to bend and twist stuff into unnatural angles just to get it in your shop and then to work on it. I would have liked to come visit, as I am naturally into what you do as well as other expert machinists who seem to oftentimes in the States, as apposed to the UK, have just about as much room as they want and as many machines as you can throw a cat at, mainly I am guessing because there is a self generating interest in machines and running a workshop by the people and special interested engineers, and that self induced work is followed by large and small companies selling all sorts of things that oftentimes there is just not such a large ‘inbuilt’ market in the UK from which to introduce these. I WOULD have liked to visit as I say but living 4000 miles away it is just not possible ;=) :=D Sincere best wishes with the electrical tests by the electrical Authority and hope all goes well. I know here and sometimes there in the USA sockets or I think you call them ‘convenience receptacles’ are a ‘second thought’ kind of thing and the electrical sockets and stuff is run from the house electrics where it in not three phase. Take care and forgive my vociferousness. mrbluenun

[@FastEddie007007]

I really enjoy watching your videos and thanks for sharing your experience with us. If you have a 5 hp motor, say on a lathe that you are powering on your rotary phase converter. If you turn on lathe and just let the motor run with no load you are adding to the total hp rating of the converter. It is almost like another idler motor on the converter.

[@VintageMachinery]

+Charles Shanafelt To a point, that will help. But, you are limited to the total amount of amps that you can draw on the system so there are some limits as to how much this will add.

[@harryq4792]

[@ccfoam]

Hi Keith I've been spraying foam for about 15 years... Spraying ceilings is messy. My suggestion would be to get the foam done as soon as possible because you'll need to cover everything including floors, walls, light fixtures, windows and beams to keep the overspray off. Foam leaves rings on anything it touches....If you cover the ceiling with drywall you won't have issues with your insurance company, If you leave the foam exposed, you may have issues. They make ignition barrier spray on coatings, but they are not cheap. Be aware that if foam get hot enough it will burn like tires. Check out North Carolina Foam industries in Mt. Airy, NC for info..... Nice shop!

[@VintageMachinery]

+Chuck Castiglione Thanks - I have to find somebody around here that does it. I have not had a chance to track anybody down yet.

[@petermundy3339]

Shop is looking great Keith, the center overhead lights Really look great and I am sure they will serve you well as far as light output. I can see those Casters underneath your furnace, I know you have plans to use a pallet Jack for moving it but with casters and a detachable handle of sorts it would be less cumbersome to move and also to store, Just a thought..

[@VintageMachinery]

+Peter Mundy I am afraid that the plastic wheels would melt if they were on the furnace.....

[@petermundy3339]

I didn't realise they where plastic ohh well I am sure you will find a home for them

[@joetiller1031]

Keith you are right using rotary for your shop 3ph.love your shop those high bay lights are really cool and cant beat the price you got in them.

[@VintageMachinery]

+Joe Tiller I bought a couple of similar lights like the ones up high but with a bracket to mount on the wall out side. Two of those new lights cost more than what I had in the 16 I did myself!

[@danbentler9742]

Keith That was a very good discussion on VFD vs RPC in larger shops. Re paralleling two RPC - yes they can be paraleled - alternators are all paralleled to the grid. All you need is a set of sync lamps to do this.. However to ensure proper load sharing you need to be able to control the prime movers (motors) speed. Two or more motors are connected to very large loads but even with identical motors load sharing can be problematic. Try it but have a good set of ammeters one for each phase on each RPC Dan Bentler

[@VintageMachinery]

+dan bentler Thanks Dan - I will look into load sharing. I know about syncing the three legs.

[@ZTFab1]

[@bobhorton4750]

Shop is looking better all the time Keith. I am in the process of choosing a rotary phase converter for my shop as most of my equipment is also older industrial machines for both metal and woodworking. I must have missed this but how thick did you pour your pad in anticipation of the equipment going in? See you at the Summer Bash. Regards. Bob

[@VintageMachinery]

[@marceltimmers1290]

Hi mate. Thanks for a very clear explanation about VFD vs RFCs. I was unaware that you could join them up, and have more power to play with. In that case, RFCs are much more the logical option for most users that don't need all the VFD options. That shop is something to behold, I hope you will be able to move in soon, and start make some swarf or dust.

[@cjbilly345]

I recently purchased a Burke #1 horizontal mill but the arbor that came with it ( a 1 in bs #9 ) does not have a keyway cut into it. Is this a fairly simple procedure that any machine shop can do or do I need to use a special shop?

[@duobob]

+CJ Billy The B&S #9 taper is very shallow and it will grip very tightly if the tapers match and it is drawn in solidly. Some users of B&S #9 tooling actually oil them liberally before putting them together just so they can get them back apart again. I have not used that taper for high torque, but you may not need a key with your Burke..

[@cjbilly345]

The taper is fine there is no keyway in the arbor arm so i can't put a key in to hold the cutters

[@VintageMachinery]

+CJ Billy Cutting a keyway in the arbor should be a pretty simple process for any machine shop to do. As long as the arbor is not hardened....

[@TyphoonVstrom]

I like those daylight LED bulbs, anyone can put up a simple light socket and have very good lighting over a wide area. The big advantage of the LED's is the light is omni directional. In the video, you couldn't tell where the lighting from the windows and doorway ended and the LED's took over, so they are working very well! The other huge advantage is that you've reduced your shop's base electrical load by a few thousand watts just by using better lighting, and because they draw so much less, you can use more fixtures closer together for better coverage, and still be way ahead on the power consumption. Your thinking on wiring the shop for 3 phase makes sense to me as well, and you never know, in the future, 3 phase may be available to your property and it;s already wired.

[@VintageMachinery]

+Sideslip I really like the LED lights. We have already converted nearly all of the lights in the house to LED. As for three phase coming to my shop from the power company, that is unlikely, but if it did happen, we would be ready!

[@tom7601]

Maybe you could put a catwalk system in the overhead for your cat(s). Some narrow stairs (6") up an end wall and some paths and hidey-holes. Or, put garden railroad tracks around the overhead... :)

I had several three-phase machines in my old farm shop for which my brother-in-law who is a licensed electrician told me I would only need three-phase to start the machine after that they'll run on a single phase. So he took some capacitors and built a bank of capacitors to use as a starter for my three-phase.

[@robgerrits4097]

Nice to see that everything is coming in place in the new workshop. Sometimes you have to be a bit creative in power supply. to get what you want at the moment you need it. Seeing how it goes until now you are rolling.

+Rob Gerrits Things are coming along. Still a long way to go though...

At my house, I have open delta three phase service. The main transformer is 25 KVA and the second transformer is 10 KVA. It was originally used for running a 1955 vintage Carrier air conditioner.

[@VintageMachinery]

+Paul Kleinpeter You are fortunate. My father in law actually has three phase coming into his older house as well - which saves him a ton of money on the air conditioners he is running. The power company keeps trying to get him to convert the house to single phase but he won't let them!

[@markbernier8434]

Will be curious to know what the spray foam costs down there. Herre it is about $2.25/ sqft/inch

[@VintageMachinery]

+Mark Bernier I have not got a quote on doing the insulation yet - but I know it is expensive....

[@outsidescrewball]

Enjoyed and congrats!

[@VintageMachinery]

+outsidescrewball Thanks Chuck! (and Howie)....

[@patchaonkasat3334]

wow thats a load of info how do you remember all that another great interesting video i have really missed your vlogs over the last few days/weeks

[@VintageMachinery]

+Patcha Onkasat Thanks - glad to be back!

[@RyanWeishalla]

Nice milestone with the shop with the passed inspection.

[@VintageMachinery]

+ILGopher The inspection was almost a joke. They guy came, out, looked at the two breaker boxes for a few minuets and said I was good to go. He did not even look at or check anything else. He noticed that I had wiring checker plugged into one of the plugs near the breaker box and asked if I had checked everything and when I told him I had, he said good enough!

[@RyanWeishalla]

Did it cost you for him to come out? It sounds like a good job to have.

[@chevellechris1]

Keith, grats on the wiring approval, I can see that being a load off your mind...... and onto them... I'll show myself out.. #badpuns

[@gh778jk]

Cat in hiding !? That dog is a menace !! Toodles!! Paddy

[@ScottandTera]

shop looks great, just a thought by using motor contactors I wonder if you could wire it so that when your on a machine with a 10 HP motor it will automatically bring on both RPC and the smaller machine s would only bring on the RPC that was required to run said machine. that way you would not have to turn them on then walk to the machine. just a thought

[@VintageMachinery]

+Scott Tyndall Anything like that is possible if you know enough about electronics. We built a RPC for the museum one time that did some automatic stuff somewhat like that. I have a friend who is an electrical engineer and designs RPC's for a hobby who helped me design and build it.

[@keithkemper]

Another good video as usual And shop looks like it is coming along nicely

[@VintageMachinery]

+Keith Kemper Thank you!

Feeding a 3 phase drive with only 2 legs is also bad for the DC bus and the IGBT's. It puts excessive strain on them because the motor will demand X amperage, the drive constantly monitors the input and output of the DC bus to sense motor demand and modifies the waveform to keep the motor within its prescribed operating parameters. Since the IGBT bank is only being fed with 2 phases, it will pull the DC bus voltage down considerably to compensate which in turn drives amperage up. The traces and bus are only designed for X amperage and when they get over driven by under delivering on voltage at the input, they fail. Many drives actually will NOT even run if it senses only 2 legs for this reason as well. Most all have current sensing circuitry on the output of the DC bus feeding the IGBT bank and it will clamp the waveform to limit current to protect them and if it goes for too long, it will fault the drive out completely. Modern drives are wildly handy and very smart but with that, it forces you to also do things the I design commercial inspection equipment for the food industry and have been an engineer in several capacities in that industry for 20 years. I have around 1400 conveyors out there, all with VFD's on them. They are a wonderful thing but also can be the bane of your existence lol. One larger phase converter sized to run the largest motor + 50% would be a nice setup but if your largest motor is 10hp.....you'd be looking at a 15hp converter and that is kinda pricey as well as being overkill for running one smaller piece. Definitely got some things to think about but whatever you are going to do, its going to be great! :-D

[@Alexander470815]

+Brian Streufert The diodes in the rectifier of the supply ger more demanded. The IGBTs are only fed from the DC bus so they don´t see anything of that whats happening at the input. Only four of the six rectifier diodes are used when single phase power is connected. Ther current would be higher and also the DC bus capacitors have to compensate for much more ripple. But what you can do is feed the DC from an external rectifier and large smoothing capacitors directly into the VFD DC bus. Then you don´t risk damaging the VFD. What the main problem is that most of the VFDs want 3~ 460V which gives them arround 650V DC bus voltage. If you only feed it with 220V single phase you only get arround 320V bus voltage. However you can use a delon voltage doubler and feed the VFD over the DC bus. Then you have arround 640V no load DC voltage and you can run the VFD and the motor up to its rated power. The power factor of this solution is obviously not that good. The Motor needs a certain ratio for voltage and frequency to provide its rated tourque. If you don´t have enough DC bus voltage the motor cant give you full tourque at high speed. For a 460V 60Hz motor this would be 7.6V / Hz if you cant keep up that ratio you will loose tourque and power. When supplied with 220V single phase this point would be arround 28Hz. For this application here a rotary phase converter is clearly the better solution.

[@coffeemaddan]

+Alexander470815 The only other thing I can think of is that the IGBTs will be under more stress because the DC ripple from rectifying 60Hz (120Hz rectified ripple) will be greater than the 3phase rectified DC which has an effective 360Hz ripple...

[@VintageMachinery]

+Brian Streufert Brian - you are mostly talking above my head when you start talking about how things work in the VFD. But the gist of what you are saying is pretty much the point of what I was trying to make. For small motors, using a VFD to convert single phase to three phase makes sense but for larger motors, it is not very practical. Part of the reason you have to over rate you VFD is to be able to handle the higher amperage needed when jumping one of the inputs.

[@Richard_OKeeffe]

You shop is looking great Keith,

[@VintageMachinery]

+Rich ok Thanks Rich!

[@gh778jk]

Had a quick look through the comments.... didn't read the 'elephant in the room question' though. How do you intend to synchronise the two RFC's when you want to use them both on the same lines? Paddy

[@pjt1965]

Love your new shop !

[@VintageMachinery]

+Peter de Vries Thank you Peter!

[@charlescompton4495]

Feeling better already; enjoy all your posts and have learned a LOT! Keep up the good work and one of these days you'll be able to retire to honey-do jobs and KZbin videos, Greg! OH, watch that pressure washer; it can really ruin your floor by blasting off the finish. Try it outside on the ramp first to see how it will affect the finish. You may have known about this already but I speak from a bad experience.

[@VintageMachinery]

+Charles Compton Thanks Greg - the pressure washer did not do any damage, but it also did not remove the tire marks. I ended up having to use a big wire wheel on a buffer to get those off. Half of the floor is sealed and I am waiting a few days for it to cure before moving stuff on the new floor - then I get to do the other half of the shop....

[@waynekwoods2799]

[@Rich206L]

Al, I really missed you last week, but I honestly thought you were at the Meet 'N Greet in CA. Anyway, great video. I was wondering if you plan to put the new furnace in the new shop or leave it out at the museum? The shop is looking great and I'm looking forward to an exciting year ahead! Regards, Rich

[@VintageMachinery]

+Rich206L The furnace is actually already in the new shop. I just have not had time to fool with it lately.

[@Landrew0]

Anyone who builds a shop should watch this video. Not many projects are so well thought-out.

[@VintageMachinery]

+Landrew0 Thanks for the kind words!

[@richardhaisley1]

60079 Can you synchronize two rotary phase converters?

[@VintageMachinery]

+Richard Haisley You have to get the three legs coming from each RPC in sync with one another.

[@squensler]

Spray foam insulation is flammable, usually it is covered with drywall in buildings to control the flame spread rating.

[@VintageMachinery]

+Dennis Clos It depends on what type of foam insulation you are using. The cellulose based insulation is actually not flammable and is considered to be even better than drywall for fire protection.

[@Beverlys-Hillbilly]

On the subject of temperatures, here in southern Ontario Canada, we are struggling to stay above freezing at night, and only getting to around 60 Fahrenheit on the warm days. I should have been born down south!

[@c.barr813]

Congratulations on 60k subs Keith! Great choice on going with the rotary phase converter, on top of the reasons to spoke of on choosing the rotary over the vfd another good reason is the cost of repair in the event of a breakdown in the converter. If you ever need to put together another converter or a larger one, check out phase-craft on ebay. nice shoes btw, Columbia?

[@VintageMachinery]

+C. Barr81 Thanks - I have built a rotary phase converter before - not too difficult to do with some plans. As for the shoes, those are made by Merrell.

[@InverJaze]

One tip I can share with you Keith is when washing the floor for the first time add an acid to the mop water to get rid of the calcium carbonate on the surface of the concrete.

[@VintageMachinery]

+Jane Calder Thanks - we got the floor cleaned up this past weekend and half of the shop already has sealer on it. This weekend, I will get to move everything in the back of the shop to the front on the nice sealed floor so that I can seal the other half of the shop....

[@EmmaRitson]

[@notsofresh8563]

Have you thought about making a side room for the compressor and the vfd's to keep the shop noise and heat down? You could put it right behind the panel, where you intend on adding a shed roof later..

[@VintageMachinery]

+Notso Fresh Yes, I will probably do that for my compressor and perhaps even a dust collector for the wood shop side. Not sure if I will put the converter out there or not though - something to think about!

[@mihalyfriedl6008]

The reason while you have reduced maximum power when using a 3ph input VFD on single phase is the lower internal DC-BUS voltage of the VFD. A simple 3phase VFD has a 3 phase Graetz-bridge on its input to convert the AC to internal DC voltage. From single phase 110 VAC you will get approximateli 155 VDC (no load). If you have 3 phase input, you will get 270VDC, while the line voltage of a 110VAC system is 190VAC ("line" voltage means the voltage between two phases). The VFD uses the internal DC BUS to generate 3phase AC on the output. Of coarse if you have lower DC BUS voltage, you will have less output power. The effect you feel on the machine is depending on operation mode of the VFD, but you will surely loose high RPM torque. The low RPM behaviour can be independant from the VFD input configuration (1ph/3ph).

[@VintageMachinery]

+Mihály Friedl Thanks for the explanation - while I knew the end results, I did not know the details as to why it was happening.

[@alc818]

Hi Keith It looks like the motor on the 3 HP RPC a viewer sent you has a cooling fan which is great - it would be good if the 7.5 HP motor had one as well. I would mount both the RPC's (3 & 7.5 HP) at ceiling height with plenty of air circulation and incorporate rubber isolation mounts on each of them to reduce noise pollution in the shop. RPC's should also be de-rated, i.e. it would be best to use a 7.5 HP RFC to power a 5 HP machine, especially for continuous operation . I'm sure you realize (for safety reasons) that you will need to make it impossible to connect both RPC's so they power your breaker panel bus at the same time. I'm quite sure the RPC's you have are not capable of phase synchronization. A good transfer switch would take care of it. It would also be good practice to use a magnetic contactor to start the RPC's which will not allow them to automatically re-start after a power failure. Otherwise, the machine the RPC is powering will re-start automatically when power is restored unless each individual machine has it's own magnetic starter. Also, it would be best to identify the High Voltage leg out of the RPC with say, a red wire and do not use this leg to power the occasional 110 volt light, fan, etc. that may be mounted on a machine. Rotary phase converters produced a delta output, meaning one leg (the generated one) will always be higher voltage (to ground) than the other two. The theoretical voltages are 120 / 120 / and 208. Actual voltages may be slightly different, depending on the exact single phase voltage coming into the converter. The same is true of any three phase delta power supplied from the power company. Having said this, having high voltage on one leg to ground is completely irrelevant when powering a 3 phase motor, because the only voltage a motor sees are phase-to-phase, which should all be pretty close... typically within plus or minus 10% or less. The high leg in the converters I use is always identified by a red wire. Once again, voltage balance is always a moving target with any phase converter, and depends on the inductive and is based on the mechanical load on the system at any given time.

[@VintageMachinery]

+Al C You are right on with your comments. I am not sure about the factory built 3 HP RPC, but I know for a fact that my larger one has a magnetic contactor in it to start it up so no worries there.
