All I Want for Christmas is a Surface Grinder - New Machine Day!

[@pauldevey8628]

Merry Christmas! Man your videos do not accurately represent how small and packed your shop is. You are an organized man with magic videography skills.

[@VagiPeti]

Totally agree on that!

[@neildarlow]

He actually works in a Tardis! 😆

[@fakerfake1]

Congrats on the new grinder! As a former tool and die maker, make sure to grind your mag chuck in after the machine has settled (typically 3-6 months).

[@tonyray91]

Good advice and by that time James will have gained the feel needed to do it correctly.

[@Joebobasshole]

Yep she’s fake friend real drug dealer

[@candynevadacinnamon5527]

Just fyi, get two DIN rail end stops to hold the phase monitor more securely. The are usually plastic or metal. However, you might need to use a slightly longer piece of DIN rail.

[@joebusfield446]

Love the googly eyes

[@edo8697]

Congratulations! Grinding is my favorite operation, you will love it. Grinding dust is my least favorite- it will get on every machine way and surface in your shop and house, more importantly your lungs, and the lungs of your loved ones. I hope you invest in a good dust collector with heppa filter soon, it will be the best add on to your grinder you will ever get. I strongly recommend a good filter mask for the operator even with the collector working. A spray mist or flood coolant will not prevent this problem.

[@vincei4252]

Wow, thanks for the warning about the shipping scam from the first seller. I'll be keeping an eye out for that trick. That said, congrats on the new surface grinder! I have a 60? year old Brown & Sharp 510 on a palette in my garage with all it's original paperwork and the sales invoice - one previous owner who was a guy that had it in his home shop. [edit] Yep, getting it off the palette is gonna be interesting. If I'd known I would have asked my neighbor who brought a fork lift over to take it off the palette.

[@outsidescrewball]

Congrats!! Tips…have the cloth wet, prevents fire and HOLDS grinding dust….get flood coolant NOW…this controls the grinding dust and of course heat, you will need splash guards for the coolant.

[@charleskeller4288]

+1 on flood over mist! i am not current on best additive for the water, but that ingredient is important too,

[@jfl-mw8rp]

Wheel type and dressing technique will have a large effect on the resulting surface. Check your wheel balance too. I have never seen much surface finish variation between dry or wet.

[@anmafab]

Congrats on the SG! It's in good hands

[@reinierwelgemoed8171]

Awesome! I am so glad you got your surface grinder. I literally watched your video yesterday where you went over to a fellow utuber to use his surface grinder and you made a comment saying that you need to get your own surface grinder. Merry Christmas.

[@jasonwilliams773]

Looking forward to learning how to use the surface grinder from you. Thanks for your videos. Have your subscribers seen this use for the vise swivel base we all promptly remove and store? Credit goes to Jeff at Adventures in machining on you tube. He had a few clever ideas and uses machines that can be kept in your garage. Search: No rotary table no problem. Adventures in machining.

[@kepotret]

Hi James, i had some experience too on kanetsu magnet chuck, its not fully magnetic . the problem was magnet block inside got lose/shift so even you turn the handle at max the magnet block inside not fully contacted to the top plate ( i think because its dropped during shipping) so what i did is disassemble the chuck, put the magnet in correct position, an done. idk its the same problem or not, sorry for my bad english, merry christmast and happy holidays 👍

[@adamalterman6657]

I like the Googly eyes

[@adamhunt8522]

Merry Christmas!!! Really enjoy the content and have found many of your videos helpful.

[@rickmellor]

Muscle memory? I call BS! We all know you're already working on an electronic surface grinder drive kit. 😀 Merry Christmas, James.🎅

[@somebodyelse6673]

I'll give it a year before James CNC's it :)

[@johnlennon335]

I've moved some machines. I would have completely strapped that machine to the pallet. Also when using a pallet jack, strap it down securely to the jack.

[@GT40Nut]

Congrats getting a surface grinder. I don't use mine a lot but there is the whole "right tool for the job thing." I'm hoping you make a wheel balancer, as one of your first projects.

[@Clough42]

It's on my list.

[@tonyray91]

Go on James make it a dynamic balancer they’re really cool.

[@jamsden]

Does… Does that machine have googly eyes?

[@flikflak24]

just asking but did you "dust" off the magnet ? it is recomended to ever now and then to just clean off the top of the magnet with the wheel ( so its flat/plain with the axis of movement ) also you want as much of the vise on the magnet to give it as much magnetic surface as possible and the workpease contact time as shot as possible. so like have the vise and work pease set on like a 45 degree angle to the axis of movement. that was it also put the least amout of heat into the part and if your gonna use oil then please use grinding specifik oil and not the normal one made for like mills btw i had the same surface first time i used a grindr and got told by a teacher that it was because the steel was to soft for grinding hope your going to enjoy the grindr

[@justinhillpac]

I love new machine days! That’s so awesome it finally made it safely. Those googly eyes tho. . 😂 Merry Christmas!

[@christobacon1]

For the 3 phase protection, I'm wondering if you were to make sure that the wild leg is one of the two thay goes to the transformer could it disable the machine unless you have the phase converter on? I mean if the third leg isn't present and it's one of the two legs that allows it to make the relays work and the latching switch to latch and so on but it's not energized non of that stuff would work. And if my solution can work, would it be better to use the monitor relay still or maybe even use both?

[@907jl]

Congrats James! Newbie grinder here as well ( Harig Super 612 ). Highly recommend the mist cooler( I'm running a Kool Mist and their Formula 77 and very happy. Big Improvement over dry ) Wait a while and get your poop in a group before you tackle grinding your chuck. DAMHIK! A porous ceramic 46H is a good general purpose wheel. Your Acra looks like it's loosely based on a Harig type design, and they ( Acra ) seem to me one of the top Taiwan imports. Bet it will serve you well! I know you're going to to square away that wiring loom once you get the proper safety device from American Rotary. It'll drive you nuts if you don't! 🙂

[@RichardBetel]

I've got a story from the early days of RIM (aka BlackBerry), that seems relevant. When we bought our first large UPS, the batteries were 2 boxes, each about the size of a small hatchback. The shippers kept calling and asking if we had a loading dock, and we kept saying no. They showed up with the batteries loaded on a truck with a 1-ton liftgate, but the batteries were 2 tons each. The truck driver asked where our loading dock was... In the end, they brought a second truck, also with a 1-ton liftgate, and put the trucks back-to-back, and tried to lower them together. One of them gave out, then the other, then the battery rolled off the gates because they didnt remove the lift trucks, the battery fell over on its side and was trashed, one of the delivery drivers went to the hospital because something smashed his knee, and the fire-department was there for about 4 hours because the front entrance to the building was covered in battery acid and the broken batteries welded themselves to the frame. Batteries were shipped at like 1/3-charge because if they were fully discharged, bad things could happen and they wouldnt hold a charge properly after that... So the fire department had 2 men dressed in the heaviest rubber suits you've ever seen dismantling the 1000V DC battery stack leaking concentrated sulfuric acid in front of our head office for most of a day... Honestly, I dont know all the fall-out. I know the shipper lost a few contracts, a driver got workers comp for at least 6 months, and the shippers got the mother of all OH&S (aka Canadian OSHA) audits. We had video of the cleanup that was used in training new hires in the team that designed battery systems for blackberries. So yeah, patience is the most important thing. Apparently, the shippers had a truck with a 5-ton lift gate, but it would have taken several hours to get it on site and they didnt want to wait.We were assured they "did this all the time. it'll be fine!"

[@DudleyToolwright]

If you don't use flood coolant, wear a respirator, especially when you are dressing the wheel. Grinding generates a ton of very fine particulates.

[@TyroneDamShewlaces]

I say screw the muscle memory thing. CNC that longitudinal feed. One axis with a speed ramp up & down at the end of strokes for smooth operation. You could sell the one-axis controller like the e-leadscrew project. I guess you could get fancy and CNC both axes, but the longitudinal would be a MAJOR labor saver.

[@19672701]

Congrats on getting a undamaged grinder,frieght companies are just horrible,I do have a decent one near by. I've befriended several millrights from working in a factory for a few decades. I don't get a discount,but they know a lifetime of chastising will be in order if they crash my stuff. Fantastic looking grinder,should serve you well,I'm getting jealous of your home shop. I hope you and yours have a wonderful Christmas and a Prosperous new year,and thanks for your great content! Hope to see more in 23'

[@wileecoyoti]

Congrats on the new machine! Surface grinder has turned out to be one of my favorite machines, I suspect it will be for you too.

[@mumblbeebee6546]

“Chestnuts spinning on an open grinder…” Congratulations, James - that is a nice new tool and plenty of learning coming up which you will generously share with this armchair machinist, I am sure. Being only a casual watcher of machining I reckon that you know more better sources, but I have to throw Rolls Royce’s own Mr. Crispin into the mix here, I enjoy his expositions on grinding as much as his treatment of his brother ;) Merry Sparkmas!

[@maxcactus7]

James gets a grinder delivered for Christmas and I'm excited like it showed up in my garage! Can't wait to see it being used in future videos.

[@maikeydii]

Regarding the thoughts about the surface finish on the test part, a 0200mm wheel is at the lower end of wheel diameters where wheel balancing will begin to take effect on the surface finish.

[@SolidRockMachineShopInc]

Hi James, The finish may be better if you never turn the wheel off after dressing. The torque of the wheel starting again can cause it to shift a little from true causing a finish like you had. Also, flood coolant can be cheap. A subscriber of mine recommended a fountain pump which was cheap and I bought a tank on sale from MSC form about $100. I have been using it now for many years. You can also get a 25 Micron filter bag form MSC and place it in the return line to filter the coolant.

[@1pcfred]

Yeah we pretty much didn't turn grinders off all day. If you're running a machine then you're running it.

[@joernd8449]

The only grinder in our shop you can shut off and restart without redressing the wheel is our big wet grinder with a 16 inch wheel that you spend about half an hour balancing.

[@1pcfred]

@@joernd8449 I doubt our wheel dressing experience was typical for the trade. I worked for a company that had a machine shop and sold industrial diamonds too. From what I was told the only thing that kept that business afloat was the profits from selling diamonds and the shop operated at a loss. From what I saw I have no problem believing that was the case. But we did have some really nice grinders. Our big wet grinder was a 4 footer. The table ran on tracks on the floor. I never got too close to that machine because the guy that ran it didn't let anyone near it. He was a little squirrely. I guess everyone in that shop was kinda off their beam. It was a regular nuthouse. Good times.

[@randyshoquist7726]

I occasionally forget to turn on my RPC before switching on the mill, but I hear that distinctive 1-phase hum before my hand leaves the switch, so it goes for less than a second. I'm sure it takes much longer than that to do any overheating damage. Anyway, so far so good. 30 years now. BTW: Googly eyes? I suppose with a smiling rotation arrow it was an obvious upgrade.

[@dom1310df]

I'm pretty sure that the seller asking you to contact them outside of eBay to arrange shipping is against eBay's TOS. You are supposed to do everything through eBay, or none of it.

[@erik_dk842]

Yeah. James should have reported him to eBay right there

[@outsidescrewball]

Spray mist keeps the grind cool, but now the dust has an adhesive…..dry,mist, wet they each have their merits & mess

[@russnixon6020]

James, the googly eyes make the ambience of the machine pop. Congrats on the new tool.

[@jeremylastname873]

What a great delivery person! Job well done!

[@squelchstuff]

What a tortuous journey you've had getting a surface grinder, but seeing the care taken during delivery must make it all worthwhile. Interesting gotcha on the interlock too. Thumbs up for the googly eyes, and happy Christmas to you and Mrs Clough42 James.

[@KevinBrowder]

DIN rails are great, tons of stuff slots in and you can print clips for non standard things; wish they were more common in the US.

[@melgross]

While I have no problem with using DIN rails, as I use them myself, and large equipment I bought for my own company that was built in Europe had them, there is one thing I’m seeing here that I don’t like. Nothing I’ve used has been as loose in the rail as the socket you’ve put in. Rails really should be horizontal, not vertical. Still, I’ve occasionally seen them installed that way, but that gives much less support as the latches are designed for horizontal rails. I like using a fiberglass filter on the shield as the garbage is collected in the fibers. McMastercarr sells boxes of paint filters which I use as well as for my powder coat spray booth I built. They are frameless as so can be cut to whatever size you want. Very effective.

[@bobuk5722]

Hi James, first happy Christmas! That control relay socket should have come with a spring clip to hold the relay securely. Normally there are a couple of indents either side of the socket to take the turned in spring clip legs. These sockets are a very good way of installing a relay, if the relay ever does fail they are very easy and quick to change out. I've made extensive use of them for interlocks. Whilst waiting for the 'right' relay I suggest putting a stick it note on the control box - "Turn on convertor first" - I would need that myself! Congratulations on the machine purchase and I'm sure we all look forward to seeing it in use.

[@notsonominal]

Dang, should have used Alibaba, would have gotten at least 10x the problems for half the cost! But hey, congrats ont he new toy (ehm, tool!)

[@VagiPeti]

Merry Christmas James! Seems like your patience and perseverance earned its reward! Congratulations for the machine! I was just wondering / become curious how is it possible to protect your fine machines like mill, cnc, lathe from the fine dust coming from the surface grinder. Maybe that's not an issue already, I am just curious, not arguing....

[@terrymoorecnc2500]

Sliding axle trailers are common in the machinery biz. Anytime you see a Harig that is shipped with the witches hat on that's a huge red flag that the dealer doesn't know how to pack and ship the machine. I've sold a ton of those machines and the machines are always blocked and framed at the factory. Ball way or needle bearing machines are always transported with the table blocked and the balls or needle packs in a separate box. In short, as you found out, buying used machines from dealers is always a leap of faith. Get a harder wheel to dust the Chuck after you stone the back off and remount the Chuck. It's always best to use the lightest torque on the mounting bolts on the Chuck so you don't warp the table.

[@adven999]

As for your grinding debris issues.... 'the angle of incidence equals the angle of reflection'.... I'm sure you can come up with a more elegant solution... just saying. Happy Christmas.

[@davidlong3521]

My experience with my manual grinder and coolant.kool Mist, corrosion problems. Unist mister, ok. Flood with Tri Cool TC 1, the best. Use a 5 gal bucket with pump from Master, 3/8" hoses and 3/8" auto online filter.

[@orangetruckman]

I’m baffled with how low your subscriber number is 🤯 how you don’t have over a million, I just don’t understand 🤷🏼‍♂️ Glad you got the grinder. Can’t wait to see the projects you’ve need the grinder for!

[@TheMudfly80]

Thanks for the freight advice, I nearly ordered a grinder to be delivered without insurance a month ago, glad I didn't now. Can you say approximately how much the ACRA is? Thanks.

[@phonefixtoolsphoebe-china]

I would like to invite you to review our microscopes and industrial cameras. I have sent you a cooperative email and look forward to your reply

[@johnfriend240]

Also present when Stan's grinder motor toasted at the 2021 Bash. The 240 volt feeding my RPC goes through a disconnect switch. If RPC is not on, there is no voltage on any of the three lines, thus cannot repeat Stan's problem. At work, most of our products utilized single and three phase monitors at customer's request. Relay base ought to be much tighter on the DIN rail than it is.

[@gregm.5960]

I guess this is a bit late. My old German supervisor taught me that you can't make a cut bigger than .0005 or you will burn the metal, Without coolant on a grinder. With his advice, I would take .001 rough cuts and do .0005 finish passes. I hope this helps.

[@pixiepaws99]

It's a Hyster 70. That thing is like a feather for that forklift... Also, why bother with a rotary phase converter? Just use a VFD that generates cleaner power and be done with it.

[@sto2779]

2:23 - Smart you paid for insurance. I think it was better you bought a new surface grinder, these things in the shop you would want to buy them brand new, making parts going sub-micron tolerances. Wow twice a surface grinder shipping failed on you lol, I guess it was surfing its way to you.

[@RRINTHESHOP]

Merry Christmas, very nice.

[@dom1310df]

What was the reason the the 3PH motor in the first place? Is a North American voltage 1PH/2PH motor not powerful enough for this application?

Wow, that looks like a hand- drawn electrical schematic. You rarely see those nowadays. Interesting! (P.s. the schematic also shows R and S, so it's weird that the terminals actually connected are R and T.) Congrats on the present! I'm gifting myself a 3D printer this years. :D Ps2 yes, I noticed the eyes XD nice easter egg... Christmas egg, I mean

[@alan-sk7ky]

Unless you are going to mask up and glasses up every time you use the SG you need the flood cooling + dust extraction as needed to at least keep grinding dust/grit down. It will get everywhere. 😐 Nice little machine though, ripe for a retro power motion project ;-)

[@GrahamHomes]

A quick smear of tallow on the finish cut really lifts the finish. As pointed out below dressing makes a huge difference ... an old rounded diamond passed slowly will really close up the wheel. The old guy who taught me would sweep his ( trailing ) finger very lightly over the running wheel to dislodge loose grits and gauge the quality of the dressing........You will not be shown that nowadays. You will need coolant if you chase accuracy. The wheel and the work heat up in the cut. On large work piece you will be cutting more as you proceed across the work. This particularly true when dressing the mag table.

[@stephencox4224]

Trick with any machine but especially surface grinders if you want perfection is to run the machine up to operating temperature before cutting any metal, This was taught to me by the man who invented childproof caps for food and drink containers who ran a one man shop that as far back as the late seventies actually had a bank overdraft of $200,000 Aud a month which shows just how valuable his abilities were considered by the big corporations that used his expertise Branco was a master in every way

[@JMakesWell]

Quick note : you’ll hear a lot of people talk about balancing your wheels. I’d skip that altogether for aluminum oxide , ceramic , etc vitrified wheels. The degradation of the the spindle taper and the sleeve from constant removal + the time to balance every wheel is unnecessary. If you’re using something like a diamond wheel with an aluminum hub and limited material to remove to true the wheel then I’d balance that. eccentricity can be dressed out without a balance on small grinders.

[@fladder1]

Congratulations! Love the googly eyes. And nice timing, mrCrispin released some great videos on grinding last week. Can highly recommend.

[@designandbuild3953]

That's a lousy circuit diagram! In the upper section, connections are marked with a dot, and unconnected wires with a crossing line without a dot. But in the lower section, wires that MUST be connected for the circuit to do anything have no dot!

[@jesseskellington9427]

Thanks so much for showing all the trials and tribulations that you experienced I really appreciate it 😊

[@anthonycash4609]

I'm very glad you finally got your surface grinder. But anytime someone starts telling you we only have air ride trucks and any other bull shit you need to start doing your on research. It basically boils down to the driver every time. My wife ordered a dishwasher 2 years ago when it finely got here someone had ran the forks on the fork truck through the front door and out the back. The driver started with his bull shit saying well I have to drop it off and you have to call the seller and deal with them. Apparently they didn't know me. I walked to the cab of the truck took the keys and told the guy good luck getting back that the truck now was staying here then the seller will have a truck to haul it on when I get up with them. Then I had his attention all of a sudden it was ok he would leave it on the truck and carrie it back. Give no shit and take no shit

[@ErnestDuarte]

Lol you should have seen them delivering a 30k lb machine into my loading dock with that trailer!

[@brandontscheschlog]

Thanks James for the info on the phase monitor. American Rotary salesman should be telling telling customers they need one of these. You either discover you need it by attempting to start a 3 phase motor without the phase converter or you find out about it after you purchase one and then the salesman try’s to tell you that you need a different phase converter that costs more money. Ask me how I know!

its not uncommon for relays to have tube style sockets, but its usually the larger one's and today mostly reserved for control modules (like you have or a time delay or whatever) most of the industry moved on to the "compact" blade style sockets decades ago for just simple on off relays

I see an ELS adaptation to the grinder hand wheels;)

[@DudleyToolwright]

When you fist get a grinder here are the things Steve recommended: Before you put on the vise you grind the bed (I skipped this and the next step because I was too new to trust grinding the bed), then you mount the mag vise and grind the surface and rear fence. You should plunge grind the rear fence. Then to see if you have done the job correctly, you grind 5 pieces of material - one in each corner and one in the middle. Measure the thicknesses and they should be identical to each other to within whatever flatness you are going for - like 0.00005". You need to make final passes with very little material removed (0.0001" to a spring pass) AND coolant to prevent the vise from heating and moving into the grinding wheel. I hope this helps.

[@brandonedwards7166]

Would it not be easy to use a 3 phase contactor triggered by the switch of the rotary phase converter?

[@grizzlyrideemwet1698]

James, Enjoying your channel. Since your phase converter leaves the incoming legs live even when off, I would suggest putting your trip relay on the primary side of the transformer, just to eliminate the parasitic loss in the transformer when you're not using the machine. Obviously you'd lose the ability to switch on the light w/o the phase converter, which may be more important to you.

[@amundsen575]

[@scrout]

Hell, you know you could deadlift that thing 💪

[@1pcfred]

I've run a manual surface grinder. It does take some practice. I had to laugh when you were touching off with the wheel. Usually you just feed down while you're traversing. We never used vises. We just put work right on the chuck. You really have to traverse pretty fast. Then do your step overs a little at a time.

[@Clough42]

A vise or a block is pretty handy for squaring.
