yes, I was thinking I would probably have the mounting plate welded on the end and then have a hole in the side to post the motor in and allow it to be mounted up, just hoping there will be enough room to get the pullys on doing it like this.

the other think I'm just trying to think about is mounting the ball screw blocks, and having a method to adjust them a little if needed so rather than mounting them direct to the steel have a plate in-between them with some elongated mounting slots?
