No 11-1/2 tpi either...

what is that you need 13 for?

1/13 = 0.07692

2mm looks close. = 0.078739

Not really a need at this point for the 13, I just know it is coarse for the 1/2 inch fasteners.

Thanks for the math and I'll see what gears I have and post back what I come up with.

Thanks everyone for the comments.

Scotts, have you checked your manuals for change gear information yet?
I helped a buddy get his big lathe moved into place and wired in. Took out the wall between the machine area and the welding / mechanics area. Took a week but we moved the 6000# hunk of iron from out in te cold to it's new heated home. We also improved the new wall by using 2 X 6's instead of 2 X 4's.
You might want to put up sacrificial wall covering so you do not coat the area behind the chuck eith oil.
Have fun.
Dan.

I did a little paying job on the lathe and this showed up.

Considering how the weather is going It was warm enough so I got started on the post through the compound here are a few pictures.

1 warm enough

2 box of goodies to support Chicago gangsters? Yes, from CDCO tool

3 The whole lathe was made in china why not continue?

4 I got the post out, it helps to clean stuff up and take it all apart to see the set screw.

5 That little half circle is threaded and so it the other half circle in the compound.

Lets get to where I am so far.

1 sitting there just to get a first look

2 Parts comparison Need to make the one on the left screw into the one on the right. 5/8-11 ought to do. What say you guys?

3 O.D. turned, my feet got cold. Done for tonight.

I'll get this turned part separated from the bar stock after drilling and tapping. There is a bit of extra on the large od to face off. I'll probably move around when I install it and drill and tap a set screw like it is now to hold in new part in the compound. I'll cut off the threads on the supplied stud and thread it for 5/8-11 and pin it in the part I am making, there looks to be plenty of length in the new stud to do this with. I picked 5/8 because the stud is .630 inch.

Yes, the compound has been off and apart to measure and again to check fits of turned parts. It is back together again for the next operations.

IIRC, the supplied stud is threaded 5/8" - 18tpi.
But you should be able to get away with using 5/8" - 11tpi.
Dan.

Thanks Dan,

Yes the wall is not going to rust behind the chuck.

I'll get out my thread checking tool and check the threads. The ones on the bottom part of the stud are a bit iffy looking.

The finer the thread the tighter the grip.

I will say that even with the -22F ambient that my car reported yesterday morning the shop was still 53°F using only a 1500W space heater and the lights to keep it warm. My shop is 1500 sq ft but unfortunately, only 9.5 ft side walls. Spray foam is very expensive but damn, it doesn't take much to keep it warm. Now if my heating contractor would finish the install of my in floor heat I'm going to heat the slab to 75° just to do it. It will probably make it hotter than h"ll in there but there will be some personal satisfaction in that.

Before I spray foamed the shop it rained during the winter in the unheated part and covered the equipment in ice. I had a blue flame, unvented heater that put a lot of moisture inside the shop. The insulated north room was ok but the larger uninsulated south room dealt with condensation on the tin roof and made a frozen rain forest out of the larger south part of the shop. I didn't dare run the blue flame after foaming the shop as I thought that the CO would build up.
