Warco GH1440 Lathe - Part 3 - Update on VFD Install & The DEEP CLEAN

[@tamarmolerick3814]

Nothing better than finding a product which actually works. Great vid.

[@MattChiversWorkshop]

Thanks Rick, Yeah this was a good find, and realistically I didn't use much of the product, bargain at £11 a bottle! All the best, Matt 👍🚂

[@edsmachine93]

Very nice, what and unbelievable transformation. Nice job on the VFD Installation. Thanks for sharing. 👍

[@MattChiversWorkshop]

Thank you, much appreciated. All the best, Matt. 👍

Cleaned up nice. Phase converters don't give variable speed. I have VFDs on all of my machines. Even the ones that originally had single phase motors were switched to 3-phsae motor and VFD. Soft start is nice on the belts or gears. Dynamic braking gets the speed down in less time than freewheeling. Not all VFDs support dynamic braking. You can also get higher speeds than the original drive system would do, but check that bearings and such can handle it. I usually give 20-50% more on lathes. There is a loss of torque over motor rated speed, but usually those high speeds are for small diameter parts that don't require a lot of power.

[@greenshortscouk]

I'm running a IMO Jaguar CUB, single phase in 3 phase output to motor and have variable speed ;)

[@MattChiversWorkshop]

On my Harrison I have never noticed a loss of torque using a VFD, the only thing Ive noticed it on is the milling machine. I'd change the motor in it to a 240v one but it being Bridgeport it has a longer than normal spindle on, making them very expensive!! This VFD does have dynamic braking, currently it's set very low, but it seems to be very effective. Just need to get the machine into its final position, levelled, then I can get using it!! All the best, Matt 👍🚂

[@Gazman110]

Credit to the quality of the paint on the warco. Great job cleaning it

[@MattChiversWorkshop]

Thanks Gazman. 👍

[@thebadger2101]

She's lookin' good, Mate! Love the panic button hole reducer!!

[@MattChiversWorkshop]

Thanks Badger, much appreciated, I do like a laugh 😂 I've had an idea what to call the estop brake pedal too!! All the best, Matt 👍

Take plenty of time. Begin with spraying equal parts Dieseline and Mineral Turps. Leave for a day or two between coats, then spray on a water based engine cleaner. These all take time to get through and work. Then finish off with a couple of sprays or brushons of a highly flammable but effective fast evaporating solvent cleaner, like the panel beaters use before painting. This process takes time, but saves you a lot of hard work. It gets several types of hard to remove coatings off, and back to looking clean and shiny again.

[@johnkinnane547]

G’day Matt boy that looks like a different machine well worth the time you spent on it. The electrical system now looks very neat the way you have done it, great job see you on the next one kind regards John😊

[@MattChiversWorkshop]

Thanks John, much appreciated. Yes it has turned out beautifully, I'm really pleased with how good it has turned out. Now to get it moved into position so I use it!! All the best, Matt 👍🚂

[@rjordans]

The normally closed emergency stop buttons also make sure that the machine stops if the wiring to the button gets loose, that's probably why you cant find a normally open one

[@MattChiversWorkshop]

I could find them in other sizes, just not for a 30mm hole... seems 30mm is being replaced with smaller sizes. All the best, Matt

[@julias-shed]

Really neat install Matt better than I did on my Myford and that was a kit 😳 I think eStop buttons are wired NC so if a wire breaks the machine is safe. I think they are normally in line with the run switch but no doubt different for your inverter. 😀

[@MattChiversWorkshop]

Thanks Julia, much appreciated as always. I'm glad everyone is thinking it's neat, I think it's a mess 😂. Anyway I'm nearly done with this wiring malarkey... back to making stuff soon!! All the best, Matt 👍🚂

[@fester2au1]

Glad I finally got your channel up in my suggestions Matt, great work. Love your explanation on the VFD. I tried to look at this path when I bought my machine and the only reference I could find of someone keeping all the machine controls was US based and confusing with the different voltages etc and he kept the contactors in operation. I need to toss my unperforming rotary phase converter and do this now as I was going to. I'm assuming the "com" port you describe is outputting a voltage (24v?) for sensing purposes and hence why you needed to change to a NO stop switch and use the NO side of the limit switches. I've now seen wiring diagrams that seem to use a 24V power supply and retain the NC cutout circuits. Coolant issue I have the same. I bought a 240V transformer to replace the 3 phase one and it has a 24V and 110V output but seeing the prices of 110V coolant pumps here it may not be worth using. Can you confirm the model no/size/specs of the AT-1 VFD you used. Thanks

[@pauljones2633]

That was impressive! Keep up the good work Matt

[@MattChiversWorkshop]

Thanks Paul, Much appreciated. All the best, Matt 👍🚂

[@maxsimons8305]

Great choice on the VFD Matt. I put one on my Mill and love it. im really impressed that you maintained all the factory functions, amazing job! Keep up the great work, I love the videos! When you get the transformer, connect it directly to your mains power and not the output power from the VFD.

[@MattChiversWorkshop]

Thank You, much appreciated. Great advise!! Yes you should only hook up one motor per VFD. There is a junction box on the input side of the machine before the VFD, so the transformer power will be taken off there. All the best, Matt 👍🚂

[@andybleasdale7045]

Looks like a brand new machine. Well done

[@MattChiversWorkshop]

Thanks Andy, Yeah I'm blown away how good it's cleaned up!! All the best, Matt.

[@RobertBrown-lf8yq]

Wow 😵‍💫 That certainly took some cleaning eh ? The results are remarkable though… looks like a new machine 👏👏👏 What are the bedways and x-slide ways like? Good outcome all round Robert🇦🇺

[@MattChiversWorkshop]

Thanks Robert, much appreciated. Yes its turned out incredibly well, I'm really pleased with the outcome. The ways look brand new, don't look used really, there is some strange stain in a couple of areas, but it looks in the metal. Honestly this was an incredible bargain!! All the best, Matt 👍🚂

[@MicrobyteAlan]

🔆 "Don't Panic", nice shiny machine. 🔆

[@MattChiversWorkshop]

Cheers Alan, I knew there was a beautiful machine under that grime!! All the best, Matt 👍🚂

[@silver3323]

I put the recommended way oil on my lathe and it formed varnish like that. It didn’t rust, but I shan’t be doing it again.

[@MattChiversWorkshop]

Crikey, what was the recommended oil?? The way oil I have hasn't done that so far. I'm sure it was the neat cutting oil he used as coolant. All the best, Matt 👍

[@silver3323]

@@MattChiversWorkshop Actually, I think I made a mistake. Re-reading my Boxford manual it says “general purpose machine oil” for all machined surfaces. But the trouble came when I used “Slideway 68” which is a proper way oil. (These have something added to improve stickiness). I think the problem arose because I may only use the lathe every few weeks and that allowed the oil to properly dry out. I reckon it would probably be fine if you used your lathe every day. Hey ho. I’ve got some spare if you fancy your chances. Bill

[@rallymax2]

How did you get Crispin’s toothbrush!? Game changer! She’s a pretty girl all cleaned up.

[@MattChiversWorkshop]

😂 Well..... thats a whole tale in its self!! Yeah she has turned out really well, just need to get her moved into position now. All the best, Matt 👍

[@Gazr965]

Looks like hardened stuff you get on chip pans, had he been using cooking oil as a coolant/lube😎 Gaz Yorkshire.

[@MattChiversWorkshop]

😂, maybe. He was a maintenance engineer on ships, so it could be anything! But he preserved a very nice lathe underneath!! All the best, Matt 🚂👍

[@stef2198]

No remote speed control on the VFD? Some job on the cleaning!

[@MattChiversWorkshop]

Thank you. I'm still undecided on the remote speed control, if I don't make the light work I could install one there. It would make finding the sweet spot on the speed easier. All the best, Matt.

[@wadkin1973]

Lovely job, how long did it take to program the vfd

[@MattChiversWorkshop]

Thanks Wadkin, I'd like to say 2 minutes, but pressing the button to the right setting number takes forever, so I'll say 10/15 minutes. You don't need to change every parameter only the important ones, the rest are for fine tuning. All the best, Matt 👍

[@graemewhite5029]

Used to run my M300 off a static converter cobbled up to a motor to make a rotary phase converter, worked well and wasn't that noisey, but my sparky neighbour accused me of "Redneckery" and "won" me a Siemens vfd from his work. I can't say the machine runs any better, but at least I'm saving a bit of leccy ? Never used a Warco, but is the forward/reverse lever wired up backwards, every lathe I've ever used was "down" for forward and "up" for reverse ?

[@MattChiversWorkshop]

Hi Graeme, What a great neighbour!! I did wonder about the for/rev and lever direction, obviously easily remedied in the vfd. It would make sense for it to be the other way round, as it would be easy to knock it off on a long cut in the up position. Thanks. All the best, Matt 👍🚂

[@billdoodson4232]

Is that Mr. Crispin's brothers toothbrush you are using there? Joking aside, you added £500 to the asking price, if you were to sell the machine, just bg cleaning it.

[@MattChiversWorkshop]

😂 no its my brothers toothbrush 😂. Sell the machine?? I'm finding it very difficult to put the Harrison up for sale 😂 and I've no room to keep it. All the best, Matt 👍🚂

[@grumbum1]

You didn't fancy trying a strong clothes washing powder solution then... Promise me you will never get a visa allowing you to head south to check up on my machines. Don't think they have ever shined as much as yours! Looking forward to seeing Tink bits flying off the new machine at a wonderous rate. Grum

[@MattChiversWorkshop]

Nah, means buying washing powder... plus washing powder and my skin don't mix...don't fancy the rash. Maybe I should get down and check these machines...... thought you had high standards in the south!! 😂😂. When I decide to get back into machining, I decided from the off I wouldn't be one of those machinists that has piles of swarf piled high everywhere and messy machines. So I do my upmost to be as clean as possible with them... plus digging through a huge pile of swarf for the tiny part you just dropped is never fun!! All the best, Matt 👍🚂

[@Dermot-t2d]

If I was selling that I would have cleaned it like that before I sold it

[@MattChiversWorkshop]

Me too, and the original owner, but unfortunately he passed away. I won't be selling this for a while, thats for sure 😂. All the best, Matt 👍🚂

[@Stefan_Boerjesson]

How's good old Warco doing now days? Emailed their customer services about a technical question but they don't reply.

[@MattChiversWorkshop]

Sorry I don't know, not contacted them recently.

[@Stefan_Boerjesson]

@@MattChiversWorkshop Thanks anyway.

[@paulstephenson5220]

Upvc window frame cleaner on a rag gets all the dark stains off the paint. Beats parafin, brake cleaner etc..... Open the door it stinks and melts brain cells too.

[@MattChiversWorkshop]

Hi Paul, tbh I didn't even think of paraffin or brake cleaner!!! Never heard of UPVC frame cleaner.... think I have some somewhere, may give it a whirl on some of the remaining bits. Thanks, All the best, Matt. 👍🚂

[@paulstephenson5220]

@MattChiversWorkshop if it was old dried coolant then new fresh coolant on a brush rips off old coolant at an amazing rate. Deffo be getting some of tgwt citrus stuff though. Can think of a lot of uses for that stuff...... Like burned on oil on steam engines.

[@melgross]

I also don’t like rotary converters because you’re running that large motor constantly once you get into the shop. It’s very inefficient and uses as much power as the equipment it’s connected to and usually, more. Additionally, they make a lot of noise and the noise from the machinery is more than enough already. Static converters are quiet, but only allow the motor to deliver 2/3rds of the rated motor power. Since only two of the three coils are working, the motor isn’t running as smoothly either. I’d like to warn people that if they have an old three phase machine, those motors were made before VFDs became usable. As a result, running the motor at low speeds can result in more current than the motor wiring is designed to handle. I find that a short bristle brass brush is great to remove hardened on garbage. The brass is hard enough to break through the gunk, but too soft to damage either the cast iron, or steel. Looks great. Shows that hard work pays off.

[@MattChiversWorkshop]

Thanks Mel, much appreciated. You have given some great technical and general advice there on the various power sources. Good idea on the brass brush too. All the best, Matt 👍🚂
