Hex me

A few weeks ago I made the 'ratchet hubs' that went between the wheels/prop and the transmission. The hubs themselves fit nicely on our aluminum axles (as they were designed to do), but I had to come up with some way to connect the half shafts into the ratchet hub. Tums out that 3/4" hex bar slides nicely into the axles.

I drilled out the hex for weight savings. Also on the prop shaft we may eventually run a control rod through the hollow shaft for variable pitch control. If I didn't also drill the hex out I would be unable to run this control rod through the assembly.


As previously mentioned, my hex bar was 3/4", but my ratchet takes an 11/16" hex head so again a bit of milling to make them match up.

All that is left to do is secure the hex stub inside the shaft on the right. Perhaps a roll pin or two. I'll work on that tomorrow evening.
