Started Trim Tab
|Roughing trim tab skin for ribs (Full size)|
The trim tab skin is roughed up with 150 grit sandpaper where the foam ribs are located
|Match drilling, dimpling trim tab horns (Full size)|
Fitted the two trim tab control horns to the skin, match drilled then dimpled them
|Priming skin and trim tab horns (Full size)|
Primed the skin and horns. The garage temperature was 32, so I moved the parts and the paint into the house to warm them up before doing the priming. Worked ok.
|Riveted horns to skin (Full size)|
I next riveted the horns to the skin. Turned out to be a mistake, as I can't bend the ends of the skin with the horns on, so I had to drill out the rivets.
|Bending ends of trim tab skin (Full size)|
Sawed out a bend form block from a small piece of oak. Then I clamped the skin and bent the ends of the skin to form the end ribs. It came out ok.
|Match drilling spar and skin (Full size)|
Cleco'd on the trim tab spar and match drilled the holes. Next I drilled the holes in the ends of the trim tab where I just bent the tabs.
