Modify the trim tab horns for manual trim

Okay, I can hear the other builders already. Wah, wah, wah... why aren't you going with electric trim? My Cessna has manual trim and I'm used to it. I want to be able to transfer from aircraft to the other with as little thought required as possible. The avionics will be setup with same idea in mind. Here I clecoed the 2 trim tab horn parts together and then made the first rough cut with the band saw. Then I put a Dremmel sanding wheel in the band saw and finished it off. The (very small) drawing shows two straight cuts, one straight up and then an abrupt right turn out to the end where the cable attachment hole is. Somehow that doesn't seem like a good idea to me. A rounded inner edge is more sturdy and looks better. It may bite me in the butt later, but I don't think so.
Update 9/24/2010: Well, time for me to eat crow on this one. Now that I'm installing the cable for the trim tab, it has turned out to be a big pain in butt to install. I wish now (a-hem) that I had gotten the electric trim.
