OKI... I guess the single nut hub is made the same way as the 6 bolt.. The 6 bolt assy has a taper in each end, and uses tapered
splitt rings, so when the front nut is tightened, the prop hub is compressed onto the propshaft. Clever design, as if (when;-) a prop strikes the ground the hub will spinn slightly, insted of bending the shaft...

If the prop shaft are identical, i guess Mr. Seidel could provide me with the prop hub... Worst case, I could make my own...

Gnome: any pictures and measurments would be VERY helpfull...
