Looking to add a treadmill motor to a JD Wallace vintage bandsaw.

[jere]

This is what I was talking about.

There is hundreds of ways to do it and make it right but this is how I would do it. A 1/4" plate would work and use spacers cut at any length you need to line up the gear inside. Pull the armature and turn the shaft down to needed size for the gear and key it.

I like this idea a lot thanks for clarifying!

Building on the idea, I could add a second plate that is slotted for an extra direction of adjustability. Maybe make some brackets with all thread like a cars alternator/ power steering... belt tension system. that way the gears could adjusted in addition to the axial plane.
