I'm working on a table design that could involve a wooden threaded joint. I'd use the Beall Wood-Threader to put a thread on a dowel -- probably a 3/4" diameter. I'm concerned about the threads getting stripped off the screw by ham-handed users. After all, the threads are held in place by only a little short-grain. Does anybody have experience with screws built this way? Are they delicate, or are they tough?
