How are the shafts constrained? Are they hex turned to round?

That's all for now. I can't tell much from this view, but it looks pretty good.
As is the gearbox weighs about 11.2 pounds according to Solidworks. I made the side plates 1/4" thick. The Shifting output shaft I am using is the one COTS shifting shaft and is the same one the is used on the DS.

It is this one:

The shafts are 3/8" hex shaft turned to 3/8" round but I might possibly use 1/2" hex and turn that to 3/8" because there isn't much material to constrain the shaft against the bearing with the 3/8" hex shaft.

I am in fact using the cims as nuts but I am curious to know why there is a problem with this. Would it be a structural issue?
