I'm pretty sure the rod through the post shouldn't be turning in the "T" nut. It should be the nut on top, the one some of us nuts keep misplacing the wrench for.

Hi,

Yeah, that's the theory. Things happen though. I think the biggest danger is pulling the threads in the nut. When you can't find that wrench and grab that 16" crescent wrench and proceed to over-tighten the nut, that's when a bit harder tee nut may save the bacon. And I stand guilty of doing that myself.

Over all, for the home shop, it probably doesn't matter whether hard or soft. We aren't going to be so hard on them.

Edit to add: Get some chips and cutting oil on that fine looking lathe! You're making me look bad!!!!!
