Trim Tabs Complete

I finished the trim tab a.k.a. AST a.k.a. anti-servo tab a.k.a. Flettner tab last week.  I'm finally getting around to posting the pics.  I also have advice for -12 builders to pass along that didn't get mentioned in my previous posts.

Firstly the CFO picked me up a pair of clamps from Harbor Freight on sale for two bucks apiece.  Do I have an awesome wife or what?!  They came in handy for holding up the trim tabs for final riveting:

And here it is getting all buttoned up with the pop rivets:

And now for the builders advice.  It should be obvious but in case it's not, you should be using this squeezer yoke for riveting on the horns:

and not this one:

I mention it because how I was going to rivet on the AST horn (top picture, right side) was a bit of a head-scratcher 'til I figured that one out.  The other advice I have for riveting the AST horns is to only give 'em a half-squeeze 'til all five rivets are in.  Then go back and squeeze 'em down to final size, but not too hard.  It just seems to work better with the thin aluminum AST rib doing it that way.

And here they are:  Two halves of the AST trim tab, which will eventually go at the back of the back of the plane:

Tah-daah!
