Very nice work, Jesse.

Beautiful!

Got any photos? A quick search didn't turn up anything on this model.

You bought a lathe - good times ahead.

Better late than never, I suppose.

Not sure about that model but older motors often ran in oiled bushings, not bearings, which is why they have oil caps. If it's working ok I would leave it alone, as the wiring insulation gets brittle with age and pulling them apart can cause (dangerous) problems. I had a couple of lovely old Singer motors that I dumped because I considered them electrically dangerous.

About what I would expect from you, Josh. That's a LOT of basketweave! What are the grips on the revolver? They have a high visual impact!!

Mine came fitted with a standard domestic needle but it wasn't hard to readjust for 135x16 needles.

I forgot to ask - Josh, that wrist tattoo looks like the serpentine stamp pattern you like to use. Coincidence?

I do it like Dwight, the trick is to keep it damp, as he said. It's much easier than stitching, quicker and no stitches to possibly wear and break.

Funny, that was exactly what I thought, word for word!

I found a similar product here in Oz. By comparing the MSDS of Mop & Glo with what was available I found a local equivalent. It can be sprayed or brushed on and I've also used it over paint on model kits.

Yes, I know, I thought it would be a great idea for a bench grinder but when I did more research I found that it's not a good way to run a motor. If it was that simple people wouldn't bother with changing their lathe/belt grinder motors to 3-phase in order to use a VFD. Unlike a 3-phase motor a single phase loses torque and overheats as the speed is reduced, making it very inefficient. As Northmount said.

I agree. While it can be done the question is why bother? Servos provide a much neater, relatively inexpensive solution.

Hmm, being an electrician I would have thought you'd be aware that VFD's are used with 3-phase motors, all the clutch motors I've come across have been single phase. Toxo is right.

No, it shouldn't hit the needle! The timing looks like it's out. The hook should be aligned with the scarf (recess) in the needle., the needle bar is too high.

Sad. Another one gone too soon.

That's a nice approach, fairly simple and makes for easy adjustment.

Yep, horses for courses, as they say. Hmmm, soft start on a domestic machine?

I agree with Gymnast. You refer to them as hobby saws. Maybe, but by definition they are a table saw (a table with a saw mounted in it), there is no rule that states a table saw must be large and have an induction motor. And these smaller table saws inevitably have universal motors, which lend themselves to easy speed control.

That's for 3-phase motors. If that youtube video is working on a single phase induction motor I'm curious how it does it. The instructions with my VFD's give connection details for using with single phase induction motors to vary their speed. I thought this would be great for my grinder but I did some research and yes, it will work BUT it isn't recommended! The motor won't develop much torque and it may overheat. Hence the need to go to 3-phase motors. I just finished digging around for more soft-start info and Don's post about the Baldor unit is the key. That unit is intended to work on single-phase induction motors and the link explains how. The one that Constabulary linked to is doubtless the same type of unit, so I've learned something new. The Baldor information indicates that the soft-start unit needs to be matched to the power rating of the motor, so buying one at random could be a problem.

Keep up the good work, Don, you're finding out all sorts of things and saving us the trouble.

I think the last two posts have summed things up pretty well. Rosch22, that price is certainly very good (too good?) and I can see why you're interested but I think I would be very cautious about the offer. I honestly don't see how they could deliver a head unit to your door in Germany at that price. So I think you should do it, then we'll all know if it's a real deal.

I thought the "soft-start" modules were designed to work with universal brush-type motors? Squirrel cage induction motors are notoriously difficult to use with any form of speed control, which is why people change their lathes, belt grinders etc to 3-phase motors + VFD.

There are clones and then there are clones. While they might all seem the same on the surface there could be some variation in quality of parts and how they're assembled. It would also want to be very cheap, imo, because as mentioned the hidden costs can be a killer! I went down the path of looking at importing one directly (to Australia, and we're not that far from China) but by the time I had looked at all the other costs there were no savings to be made. I contacted numerous companies and while there were a couple of follow up queries from some there was no "pestering". Unless you can get a delivered quote, as previously mentioned, I would be cautious.
