Compact Joint Help Needed

[staplemonx]

Wanted to check a design and some numbers past folks to make sure we don't waste what little time we have left.

Will the GEM Gear boxes be able to handle the load?
Do we need any structural reinforcement?
Will the arm axle be able to handle the load?
Is there anything we should change about this design?



The structural members are 1x2" and are .1 thick.
The arm that is being rotated is 20lbs total and is 33" log so the numbers in JVN are increased over reality.
The extra gearbox location is in two different locations in the two images and is only being used to house an encoder.
Here is what the arm looks like:



We have blown up a few lift joints so far this season and want to make sure this one works. http://team1389.com/9-days-left/ Here is the 2nd failure https://www.youtube.com/watch?v=BjIZBcQOSe4
