Re: pic: 2x1 gearbox
1/16" wall tubing is not a great idea for a gearbox like this, particularly because the bearings are only supported by a thin amount of material and also because you have to make an aggressive pocket to leave clearance for the gear. I've never seen bearings directly mounted in 1/16" tubing that support loads as large as a drive wheel work out well.
You really want to use 12T (or 11T) pinions on an enclosed gearbox like this because you are giving up the ability to use the CIM boss to pilot the gearbox when using a 14T gear, since your hole has to be big enough to clear the gear
