Why can't you buy ACME/trapezoidal screws?
Where is ground V-threaded rod used? I thought V-thread is intended for fastening and then I can't see what use it would be to (precision) grind it?
BTW, V-thread is a lot less efficient at transfering motion than trapezoidal. That makes sense if you think about that it is meant for fastening things (preventing motion).
