I had little to no foreknowledge of telescoping lifts going into this challenge so this would definitely use several more revisions before it hit production level but I'm happy with the results.

Brendan, awesome job with such a thorough design!
One comment that may be nit-picky, but thought it was worthy to mention because the principle can be applied in the future.
On your arm pivot, I foresee issues with holding tolerances in the last stage of your gear reduction. Currently, that Center-to-Center is dependent on tolerances in gearbox mounting to frame, top gusset mounting to frame, hole location in gusset, etc. Especially with what I assume will be significant loads in the arm pivot, you want to guarantee proper C-C to ensure longevity/avoid failure in that reduction.
My initial thought would be use the gearbox plates as the gusset on that side, so the 1/4 plate goes all the way to the vertex, and you ensure proper C-C.
Just a quick comment on tolerance stack up, but overall an awesome design! Best of luck this (real) build season!

The biggest thing is you don't have to make your robot like another teams. Come up with something unique and go from there. RAISE THE BAR.....
