Bridgeport Series 1 Interact. Refit/update . Opinions please.

Had 2 different thoughts on pulleys. ( but that's all they are right now.)

A) Make a shaft extension piece and stick original gear on the
end. ( quick & simple, but depends on length)

B) Make a new gear with an extended boss.
( seems a more engineered solution, but more expensive
and a lot more time to machine from solid. Also I would
have to make a single tooth form tool. Fortunately I already
have a H/V rotary table with dividing plates)

Sickeningly, this would be a great job for the 4/5 axis machine that I hope to end up with ,but isn't that always the way!


Re mounting, my servo motors have a stupid raised boss on the front face. Going to turns this off in the lathe.

X & Y axis should be OK with a flat face.

Z AXIS mounting plate is part of main head casting and has a circular pocket machined in to accept the old SEM motor. ( no way I am stripping that lot off to mess with. Thinking of just making an exact size disk to drop into pocket to level out the surface. Then bolt motor straight on.
The bolt pattern on new motors is a little larger, so just thought of rotation the bodies 45°, marking and drilling a new PCD to suit.
