Modding AM14U3 for WCP DS Gearboxes
Recently became part of a newly-formed FRC team, and I'm wondering if it is practical to mod the AM14U3 to be able to mount WCP DS gearboxes. I've looked over the CAD of the chassis, and it appears...

Re: pic: 2x1 gearbox
So probably using 1/8" stock would be better. If the spacing inside is too little to fit anything in, then perhaps using 2x1.5 (I think this exists on McMaster) stock or something higher would be...

Re: Vex Shift Rod through 3/8 Hex Shaft?

Vex Shift Rod through 3/8 Hex Shaft?
In CAD, the shifting rod has a diameter of 0.187 inches. So I'm wondering if custom shifting shafts can be made out of 3/8" hex shaft... or is that way too small to be considered safe?
