Hello. Is anyone interested in making a metric lead screw for a project of mine. I have an SB13 lathe but Im a newby and having belt issue with my lathe. Anyways since this thread is somewhat related to what Im trying to accomplish, i figure ill post it here.
Regards.

You might get more answers if you actually posted dimensions of the part you want.

Belt issues can easily be resolved - post in the main forum for help getting these fixed.

Heres the part. Basically, its an 18mm round , with this thread( odd for 10 threads measured).

I just realized this is actually 6TPI.
the unthreaded part is 84.8mm.
The threaded part is 9.2 inches
Because this is something my lathe quick change gear can handle I might try just it.

That looks like a square thread. What is this from?

Just buy a length of Acme from McMaster?
Thanks for the info. Oddly, this is 18mm and 6tpi. Metrics seem to be listed with spacing between 2 threads with whole numbers in mm. This lead screw measure between 4 and 5 mm spacing, but nicely falls into 6tpi. No 18mm on the TPI section.

This is the lead screw which I plan to make with my SB13 lathe, since it appears to be acme 6tpi thread. The picture shows lead schrew on top, SB13 cross lead screw bottom. The thread shape looks the same.

I started this thread almost 16 years ago. No one has posted a photo of a project they have make on their lathe for almost a year. Lets see photos of some of your projects.

16" 1969 vintage. My employer bought it new. I rebuilt it a few years ago (thank you Ted!).

Couldn't find anyone to rebuild the alternator for my 65 Fury Cop Car so I rebuilt my own plus a spare. Made the pulleys. Came out awesome. When I probed the grooves on my CNC everything was within 0.001" worst reading.
