1 forum posts	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 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.
