I almost slapped an "FRC100" tag on it... But I'll resist...

Kinda reminds me of some of our drive ideas.

Our team doesn't actually ues 80/20 connectors, we use bolts with filled off heads, or toilet bolts. This spares us the aggravation of dealing with sliding, twisting, falling-out 80/20 biscuits.

That's very clever.

But how will you reache the bolt if the axle is in it? And how will you tension your chains if the wheel isn't in there?

We usually buy a kind of extrusion that 80/20 sells that already has the flat groove, and then we put the holes in it ourselves.
