   How many screws do you need to make?

   Well that depends. Wheels come in lots of designs, and most have at least one, some two or three adjustment points where screws are used. I'd just like to be able to make them to the size I need when I need them. Most are 3/4 to 1 1/2 inches in diameter and 2 to 5 TPI.

   Thanks! That really covers the screw-making very well. I guess taps are best purchased

   If it's a 'hand-made' piece, the woodworker used whatever tap & die set that he had available to him. I don't know where you're located, but you may want to see if there is an antique tool collectors group 'near' you. See if anyone has some taps & dies that you could check against your original piece. If all else fails, you can always carve/file the male thread onto the piece you're trying to reproduce. The couple of times I've tried to cut a male thread, I was experiencing some chipping on the threads until I soaked the thread area with linseed oil. It helped greatly.

   The old wood turners made their own internal and external chasers and chased them onto the wood using a very slow speed on the lathe.Try a google search on thread chasing.I regularly chase threads on ivory and hardwood and have chased the mandrel thread into a wood jamb chuck for my lathe 1 1/2 " by 6 tpi
