Awesome work, you put a lot of thought in to this! I like the speed of the screw and you have 2 threads vs one! Thought you nut could of been square in shape, and you then could of taper 2 or all faces in the leg of the bench which could be cut in in tge assemble prior to gluing up the leg! That nut would never go anywhere then, and you don't even need glue to hold it. Just "key way" pin it into place with a dowel. Basic principles of a vice as I know. The jaws must be parallel as well as the work being held. If not you need one jaw face movable or add in a piece of round stock inserted on one sided or use some taper wedge cut to the angle required to be parallel to the jaws and work. If the above is done correctly it really does not take a great amount of clamping force to hold the piece of wood in place. If you out just a sliver just use a piece of cardboard, ki use cereal box carboard) you be surprise at the grip you get for the clamp preasure being applied! Like your journey your own with your screw development! Steven Columbus Michigan 🇺🇸
That would work great I'm sure, especially to install during the built. However, this is something I thought of to replace my leg vise screw. More of an as-built appication. Although, I like the key way Idea and it could be used in either application. I suppose you could use the keyway, with the taper and maybe small furniture screws through one of the threads, into the leg and still have a very strong glueless install. This was my test model and once glued, It seems to hold quite well. Thank you for watching.
Pardon me, im a 10 year machinist just getting into the wood working world. So essentially its a 1" pitch screw with a 2 lead thread? As in one turn is equal to 1" of lateral movement but the load is shared on two threads instead of one?

Thank you Sir !
You are welcome! Thank you for watching.
You mentioned you made the screws on your cnc. How did you thread the nut?
Did you make a tap yourself?

Exactly correct. Thank you for watching.
