I made wooden vise screws (1.5" diameter) and nuts for a workbench

good example

have seen some real nice vices with wooden threads

the threads used in wood vices are typically a much coarser thread, similar to ACME...If I understand correctly the tapping that is being discussed is national coarse thread, ie 1/2-13, 1/4-20, etc, but please correct me if I am wrong...

and of course, coffee had not kicked in, or I would have corrected the spelling to "vises"
