My apologies for the slow response. I just got off work.

Something like that. I'm partial to octagons for ease of mounting.

What's holding the bearings near the shifter in? It doesn't have a flange, so it confuses me.

Its flange is bolted to the inside of the tube to save space.

Assemby could be easier with some extra access holes to stick a pair of pliers in to hold stuff still.

That's true, but I still think this design would take several lifetimes to put together, so I don't plan on ever building it.

I'm seconding Chak's question about what the bump is. Did you mill down the entire outside of the tube except for that part?

Thanks, and yes I prefer that to a lightening pattern.

EDIT: what size tubes are those?

2" by 2" by 0.125" wall.

Not enough to be worth it. This design was half way between a joke about the "put everything in the tube" hype train, and a fun CAD exercise.

Though, having a hexagonal frame perimeter might make it easier to avoid pins.

Yep, I mostly did it that way because the gearbox design allowed me too, and I like the bulged side drives.
