This may not be the proper place, but I expect it will be seen by more mini mill folks. I have tried and tried to build a reliable Z axis mount for my X2 using the Sterling plans, but I can't seem to get the timing pulley for the ball screw bored and threaded correctly to accept the ball nut with out binding. I also can't seem to keep the set screw for the pulley to bite into the tube so that is doesn't come loose.

So, I am looking too see if anyone has the CNC Fusion Z kit for sale. I have the ball screw already, but I think the ball nut I have will be too big for the mounting. Drop a line here if you have anything that will help.

Thanks
Dan
