Prop spacer help

[Gregmarlow]

Hello,

I'm working on fitting my prop, and I'm trying to simulate the space. I'm putting a 3 blade CS MT prop on my IO320X, onto my 9A (6A Cowl, because of the vertical induction).

First, does anyone have anything I could borrow to simulate the backplate? Like a 13" plywood sheet cut in a perfect circle? or 2? Not sure exactly what I need there, but it seems like I need a 13" circle to simulate the backplate, and a 13.5 inch circle to set aft of the back plate to fit the cowl to. Along with some 3/4 inch PVC, and some hardware store 7/16th bolts, which seem to be hard to find in the 4 inch variety. Any suggestions there?

Thanks!

no need to "reinvent the wheel"

I know what you're saying... just cut the circles out yourself! But, the mother of invention is laziness, and there's no need to re-invent the wheel. How's that for cliche's?

If someone has one of these, I'd be happy to pay postage and return it.

Thanks,
