Prop spinner

[cjhukill]

I'm trying to determine the optimum cutout dimensions for the blades on the 2 bladed Hartzell blended airfoil prop as Vans sells, using the standard spinner kit. The instructions tell you to rotate the blades thru full travel to check for clearance, however I don't have an engine to mount the prop to yet, and it's not possible to move the blades without one. I am trying to get as tight of fit as is possible. I have looked at production airplane's installations, and they have a much larger clearance than I would consider aesthetic. Has anyone made a template or drawings that would provide the dimensions that I need?

You can rotate the blades with a little air pressure to the prop. You don't need a whole lot.

Use two helpers to turn the blades in opposite directions while you mark the tight spots with a sharpie. Sand a little. Repeat. My wife and I did ours, but a third person would be handy. If you need more leverage then use wood workers clamps with some cushioning material protecting prop.

A note on clearances. Prop blade to spinner on mine is 3/32", which is fine. My spinner to cowl clearance is 1/8", which is too tight. I'd recommend 1/4".
