so grab a caliper and measure 3 threads on the leadscrew, is it.

The supermax series seem to have both metric and imperial threading capabilities, You need to know if you have an imperial leadscrew or a metric lead screw. So the old saying, the better the question, the better the answer. So I hate to assume that model you have, and what leadscrew you have. I looked for info on Supermax lathes, and find lots of models, all of commerical size. This is what I like to do on small diameters especially.

The single point assures that the dies will thread on straight. The other way to get a good final thread is to single point it most of the way and use a die to finish. The tip needs to be at the midpoint of the work. To save the hassle you can get carbide inserts for threading that are precise. The center gauge also is useful in grinding a HSS tool to verify the 60 degree angle at the tip. You need to have the cutting bit aligned perpendicular to the work or the threads will be malformed. Rather than relying totally on the compound dial, I would use a nut to try the fit. You can take a bigger DOC at the beginning of the thread and reduce it as you go in. The compound should be at 29.5 degrees, not "about 30 degrees".ġ/2-20 threads have a minor diameter of. Since it's a multiple of 4 but not 8, use either all even numbers or all odd numbers. For the 20 tpi, you can use the thread dial. You can't use the thread dial unless the tpi is a multiple of 4. Assuming your leadscrew is 8 tpi, cutting 10 tpi means you need to feed the carriage back to the start using the leadscrew.
