ACME tap

Hi

I am after a 5/8 inch 4tpi tap.ACME

It is to be used to cut a thread into some Delrin.Need to make a new half-nut for a Legacy wood lathe. At a push a short bit of leadscrew would do.I could macle it up to cut the thread

Thanks

An alternative is to cast some delrin (m.p. about 170 Celsius) around your lead screw. An apparent easy fix for a full lead screw nut, but might be a bit more of a challenge for a half nut.

Acme threaded rod is available from suppliers, if you wish to make your own tapping tool.

Hope this helps.
