Got a problem

[erasmussen]

I got my vacuum pump finished

Then I run into a problem, does anyone know what the threads are on the outboard side of the headstock spindle, on the HF lathe?
I found out they are monkey threads (LH)
I have metric tap and die, I also have SAE tap and die, but I dont have any LH tap and die never had any use for any.

If I know what they are then maybe I can buy 1 die some place

You may have a REAL problem finding a LH die. I frequent machine tool supplies catalogs from companies such as WT Tool. They carry a good many taps & dies. The only LH die they list is a 14mm x 1.0. That sounds a bit small for a lathe spindle, even a HF, being slightly under 5/8". Good luck.

Its the inside threads on the outboard side, close to 7/16 somewhere in that area, and they might be metric

Here's a listng to their LH TAP page. They have a large inventory of English thread taps. Just no LH dies.

Earl;

Which HF lathe is it?

If it is bigger than a 7/16 it will be a M12, M10 if smaller..
I can turn you one with the threads you need.

I will need to see it, I work in Wilson 301 and 117, I can stop by Sunday after the lumber run, and look at it. I have thread pitch gages to check the pitch..

Up to you..

What in the world is an M10 or M12 - some kind of small firecracker - has to be cause it's less than an M80

OK Oh yes I can make a M80 as well.

OK M stands for metric threads, a M10 is a 10mm dia. x 1.5 mm pitch

There is M10 x 1.25 and M10 x 1.5 , a 1.25 is fine thread.

Jeff a M80 is 3.1496" or about 3 3/16 dia.

Don't you just love this site!!!

And in the refrigeration industry what you call 3/8" is called 1/4" instead.

Does 1/4" work better than 3/8"? You got me thinking...
