Section 9-16 Elevator Trim Tab Fabrication:
My Notes:
- Step 5 Bending the ends of the trim tabs:
- Make a wooden trim tab template verbatim from the templates. Use this on the inside of the area to be bent. Now put a reverse wedge on the top so the clamps will work. Now the outboard end is square (90 deg) so offset 1/32 as illustrated then clamp to table FIRM, and bend with wood block. I skipped the double sided tape as I was able to precisely clamp w/ 1/32 offset. I used a plastic peen on the rivet gun set to 40 psi. Bend the bottom first. Use the plastic peen to sharpen the edge of the bend. - Now bend the top down and match drill.
- When doing the other end, draw a line w/ sharpie from the angle edges. Put the wood block in at the same angle as the line. Clamp to the table same as other end. Clamp it FIRM.
Section 9-17 Step 2:
I used my buddy's 90 deg "shear/brake" with a 1/4-1/2" angle iron. I slightly opened up the trim tab while gently bending to 15 degrees. Came out ok. Better than just doing it with duck bill pliers.
