In my case, I would need to cut male thread on the hickory shaft and then female threads inside the steel T-fitting... I've never seen a tap that could cut that thick of threads in steel that would match with some wood threads...Hey Collin Leon,
I have a tap & die for cutting threads inside and outside for 3/4 in hardwood. Made for making wooden screw clamps for shop. The set is not cheap at about $79.00, but lasts forever. Do no attempt to cut threads on softwood dowels as they will merely crumble to pieces. I think Garrett Wade sells a set in 3/4 in
