Another thing I never thought of. Again I will do stress analysis on it soon. However I don't believe it will be an issue. Because there is so much contact space between the bearing set up and the bracket it will be tought to deform. Unless you're talking about where it mounts on the rail, and in that case it may be able to deform, but i dint think by a lot.
-These are actually very concerning to me in this design. Cantilevering those rollers through only a 1/8" piece of metal is simply not enough. I bet if you put the elevator all the way up and pulled on the top you could bend those brackets right out. These defiantly need to be strengthened or I guarantee that they'll fail at some point in the season.

Keep up the good work!

Here's a picture of the lower bearing mount 254 did on their lift in 2011. If you recall, it was a fantastic design.
These did not get bent throughout the entire season that I am aware of.
