I’m a new member here and have purchased a slightly used 16” Delta lathe about a 18 months ago. Ive probably turned 4 hrs a day since then, other than the time spent restoring 4 RAS’s and an 8” jointer. The problem I have is this model didn’t come with the jackshaft which I purchased from ebay without the motor pulley. Everything else is there except the motor pulley. My hopes are is that someone here has the same lathe and can give me the measurements of said pulley? Looking at the publications it shows a smaller dia pulley than is on the jackshaft? I want to have a machinist fabricate the correct size double sheave pulley and have it ready to go when I change out the DC motor and controller and install a 2 hp motor and vfd? Any help appreciated.

Do you have the real model number (should be a 46-xxx) or better yet, the pulley part number? If you have the part #, you might be able to find the size in this thread over at OWWM.
If not… try posting over at OWWM as someone there should have the info you need.

If you’re going with VFD, why do you need the jack shaft unless you’re looking for super slow speed? ............ Jerry (in Tucson)

This will be a very nice lathe when you have finished with it.

It’s actually been a decent lathe like it is but on a large object at a low speed it struggles. The JS would make all the difference in the world if it doesn’t introduce vibration. I’ve searched everywhere for the size of the motor pulley and it appears to be smaller than the JS pulley. I’ve tried to find someone online to measure there’s but to no avail. I would hate to install a vfd and new motor and find I still need the JS?

Believe it or not I posted the lathe on OWWM when I first bought it along with the 5 large Henry Taylor and sorby tools. They were free as was a 14” faceplate. If I hadn’t gotten those nice knives I would probably still be using my old cheap carbon tools. I’ve since bought many more though. I also bought a talon and a stronghold for yes 50 bucks, 25ea. Bob Vaughn would be the guy to tell me how to size the pulley. I’ll post it on there later.

Why go to the expense of a VFD + conversion when you can simply put a more powerful DC motor on it?

If I kept the old controller it’s lowest speed is 300, I want slower than that. If I had the JS in it and changed the belt I would be at 150 rpms. I have another vfd on a band saw, it’s nice. I would like to have one on every machine.

Are you still looking for information on this lathe….... We have one we’ve owned since new…..... Delta made a kit to replace the motor controller etc. and we purchased this several years later and installed the items ….... we think we have the all parts from our removal…...Found your post because we are considering selling our lathe …..we have several other lathe’s (we in addition to the regular lathe purchased and additional bed and stand and extended our lathe out to 8’+ we also bought the 36” duplicator made by Delta)

Let us know about the parts and we will see what we can find…...

Can you get me the measurments of the motor pulley, if you have acess to the jack shaft model? To the other guys question about getting a stronger DC motor, I would pay a lot of money for that and it still wouldn’t compare with a 3 phase motor and vfd.

Did you ever find the motor pulley or at least figure out the proper diameters? I am in the same boat with my DL 40.

No. I’ve learned to use the lathe without installing the jack shaft. I still want the correct motor pulley and will have to pay a machinist to build me one, still don’t know the proper size though. They had two people with these lathes I’ve emailed and not one person would go to the trouble of giving me the correct measurements after saying they would, I go out of my way to help people.

If adding VFD, can you move motor mounts & motor and buy a pulley belt to fit?

I’ll have to get a 3 phase motor 2 hp and a vfd, I’ll build a controller and do it right when the time comes. The setup I’m using now works so good I’m not in any hurry. Once the D.C. Controller goes out then it’ll be time! This motor is a 3450 rpm which I find strange, it has What I call a small pulley. When I install a 3 phase unit I would like to shorten the distance by moving the motor closer to the spindle. really I would like to re-invent the wheel and have the same kind of flat belts used on a modern lathe.

Good morning. Did you ever find the motor pulley? I have the same problem with my DL 40. I purchased the JS but do not have the motor pulley. If you have figured that out please pass the info along!

I never did find the correct size. I’ve asked several people to measure theirs to no reply. I myself on the other hand bend over backwards to help anybody and go out of my way if needed. The thing to do is wait and get a vfd and a different motor and we won’t need the Js which will introduce a vibration anyhow.
