When using an A-Axis I was thinking that I could mount the work piece in two ways. I could have a chuck at one end and a flat plate at the other.

The flat plate would allow me to bolt stuff to it. I guess if it has the right hole pattern it should be easy to make pulleys. I could cut the bore and rough the outside using a 2.5D method. I could add the mounting holes that match the mounting plate on the A-Axis and then finish the pulley or gear on the A-Axis.

I could also mount odd sized pieces with the plate.

I suppose this plate could be made of 1/2″ thick aluminum? I could drill and tap the hole to match the threaded rod that I’m using as the main shaft of my A-Axis assembly.

Does anybody have a 1/2-20 tap?
