Are you using a custom or COTS shifting shaft? If so, which one?
How is this mounted?
Are the cims acting as nuts for the standoffs? If so, consider changing that to just nuts or pemnuts.
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?
