Trim Tab

Tad was able to stop by last evening and we got most of the trim tab ready for riveting. Tad built the bending break so we could complete the bend of the trim tab itself. This turned out pretty good and we just did a little at a time to make sure not to over do it. After fussing with it for a bit it turned out really good. We were both pretty happy with it.
Next was to bend the tab at either ends. We tried it first on a sample piece to gauge the bend on it and decided to sand the bending blocks a little to ease the radius a bit. Tad did the honours of slowly bending the tab down. We continued match drilling the tab and finished off by countersinking the holes where the hinge will go on the spar. The bottom of that spar has dimples that mate up with the skin.
Tad has taken the parts and will prime them... next will be drilling the hinge and riveting it together.
