Re: 973 Remote Assistance and Mentorship Program (RAMP)

On the cascade elevator what tolerances did you use on your 2011 elevator for the slides on the tubing. 2x1 tubing isn't always exactly 2" wide so I was wondering what width between the bearings worked.

I think we designed for .005" then. We now design for 0".

The bolts, bearings, plates holding them, all have some mechanical slop in there interfaces (it's all through holes, not tapped).

There is nothing wrong with adding more spacing in the plates to account for lower tolerances if you can't hold +/-.005. It will just add slop.

If too tight initially, take some time to wear it in. The steel bearings will wear the aluminum to a happy medium pretty quick.
