Thanks! I made it this morning from 1 1/2" T6 bar. I tapered the inside to fit the tapered crank and cut a key into it so it's tight on the shaft and doesn't spin I just hope I don't have to take it off again!

I also cut anti slip grooves onto the end so the prop doesn't, umm,

slip! Yeh I suppose I better go and clean up the mess!
Do you think the crank still looks long?
