I am trying to figure out how to use this old lathe. I’ve purchased a couple books and magazines to get me started, but I can’t seem to get this thing to work right. My problem is that whenever I attempt to use the lathe, it stops spinning under pressure from the chisel. It has a dead center tailstock quill, so I’m going to try to get a live center to reduce friction. Does anyone know if an old lathe like this would use MT#2?

Is there anything else I should be trying? It looks like the motor works like my table saw – the weight of the motor applies the pressure for the belt to make it all work. I’ve replaced the belt, but that didn’t do anything.

Hey Beta, a quick measurement of the quill ID should be be .700” or just over 11/16” and just under 3/4”. Without precision measuring devices, that’s as close as you’ll get. So, if it’s smaller than those 2 numbers I gave you, it’ll be an MT1.

Looking at the picture, I would suggest you put the belt at the spindle pulley on the largest OD, and smallest on the motor. See if you have the same problem. If you do, maybe you need a capacitor.

The first suggestion should have been to check the HP rating on the motor. Under 1/2 HP, will present problems …...... Jerry

You didn’t say what stops spinning. The motor, the drive spur, the work piece, the belt?

Wish we could see what is mounted on the headstock spindle. Normally use a spur center or face plate.

May be off base but sounds like wood only held by pressure between head/tailstock so when attempt to use you tool wood stops spinning. You need to seat wood in the spur center. A live center will make life easier but a dead center will also work if wood held better at the headstock.

Is the headstock spindle hollow? If so need s spur center like this;

If lathe has threads on headstock spindle but no morse taper you need something like this. Not sure if this one will work on your lathe.

would need something like this if headstock threads are ¾” x 16 TPI to make above fit.

Thanks everyone for your comments, they are very helpful. Here are some additional pictures.

Nubsnstubs – is ID inner diameter? I’m struggling with figuring out what size I need.

Bill – everything seems to stop and the motor hums, so I shut it down.

Need to start with the basics, who made the lathe and does it have a model#? Also I’d love to see more pictures, that is an interesting lathe. It kind of looks like you have threads on the spindle, then that drill chuck or collet looking thing, then a threaded spur drive.

So, I took the tailstock in to a Woodcraft store. I knew I was in trouble when they asked me if it was ever on the Ark, and if Noah gave me an instruction book….lol

They told me that this tailstock does not have a taper. They also said they don’t have any parts for a lathe this old.

Does anyone here have any experience with a tailstock that doesn’t have a taper? I can’t find any markings on it whatsoever other than the GE motor. I’m not sure where to turn (pun intended) at this point.

I’ll add some more pictures:

Can’t read the HP rating on that label but the mount makes me think it’s a refrigerator compressor motor and is just under powered.

I’d post some pics of it over at the Vintage Machinery site and someone will positively know who made that. And if you know someone with a metal lathe maybe your tailstock can be turned to have a taper.

Beta, post 4 shows you holding what looks like something that came out of the quill. It also looks to me like it’s about a 2MT, unless you have a dainty and delicate left hand. If it didn’t come out of that lathe, where did it come from? It does look a little short for MT2/2MT. ID is inner diameter. That part you are holding should be about .700” just before the groove, and taper down to .572” at the narrow end. The taper should also be 2.5” long to be a 2MT.

When you took the tailstock into Woodcraft, was the center you show still in the quill?........... Jerry (in Tucson)

It should be no problem with a dead center and I don’t think a live center will help very much unless you really cranked down on the tailstock pressure. At 1/3 Hp it is going to be easy to stall under the best circumstances.
In the latter pictures of the wooden pulley on the headstock appear to not be V grooves and are very shiny. They appear flat with straight sides to me.
It it has a V belt it would slip with almost no pressure.

Thanks all.

Yes, that piece was in the end. I bought an MT2, and it is just slightly too big to fit. It is roughly 2 5/8” long, and the small diameter is about 3/8” and the last part that fits in that hole is about 1/2”. The taper is roughly 1 5/16” or 1 3/8”.

It appears to me that the center fits in the up to where the center gets rusty. The end (small diameter) of the center stops about halfway through the hole in the cylinder. I’m assuming the hole is for a screwdriver or something to pop the piece back out…? ...These are all guesses on my end.

It does have a V belt, and to my eye, the v belt appears to fit perfectly, though I am certainly open to trying something else…

This lathe was originally my neighbor’s when I was growing up. This man was all kinds of amazing with woodworking. He died at 92 years old about 12 years ago, and his wife let my Dad pick out a couple items he wanted, and this lathe was one of them. I always wondered why Dad had never really used this lathe, but I think I’m figuring it out now….lol

Go through this photo index to see if there’s a match. Select Lathe, wood and have at it.

I’m still striking out.

Can anyone help me identify the taper of the center I have in my hand in the picture above (nubsnstubs?)? Here is the best I can do with measurements:

Sorry for how terrible this is, but it was the best way I could think of doing it. Anyone have a guess? Or can anyone suggest something that might work, given the dimensions? I can say that a MT#! is too skinny and an MT#2 is too fat.

You can find the dimensions of common tapers here... what you show is close to a Brown and Sharpe #5 taper, but not exactly as it is longer than you show. If you can calculate the taper per inch it might give a better indication.

As for stopping… does the motor stop when it happens? Or does it keep running and just slipping the belt? The tail stock should not be a concern, it’s the headstock and drive arrangement you need to look at for problems. And it does look like those wood pulleys are not designed for a v-belt… have you tried turning the belt inside out so the flat part rides on the pulley instead?

Cheers,
Brad

PS: I doubt you will find out who made that lathe… it looks more homemade than anything else; wood bed, banjo and pulley give a clue.
