Yea, I can see where square threads would definitely need to be fed straight in.
Hmmm, this talk about acme threads reminds me I have a project that is going to need an acme thread cut. I need to make a tailstock to use with my spin indexer for supporting work between centers. It probably doesn't need to be an acme thread but it'll be a good opportunity to get some experience in cutting them.
Thanks,
