Default 3 Blade lower cowl Mods

Struggling with pix for now

Read a lot of post about the extended opening required for a 3 blade prop but had to guess at measurements. Sharing pix of my modification after swapping a 2 blade Whirlwind for a 3 blade Hartzell composite. Should be at the Hartzell display at Osh...oops Air Adventures this year if you want a closer look.

Removal is not fun but doable with two people, protect the blades by covering the hinge on top of the bottom cowl (I used brake tubing and trying different sizes of PVC trim from McMaster Carr) I'll share when I get it right.

Tie down the tail to lift the front wheel off the ground (chock the mains first). Tried it without this step and it can be done but very difficult, you pick up over and inch of clearance.

Cowl installation seems easier if you slide in from the side, tape up anything you don't want scratched up. Remove the front gear leg cover, pants can stay on.
