After hours of researching the Forums and a lot of head scratching I began construction of the Trim Tab. I had already completed the trailing edge bend of the tab a while back so it was on to the marking and cutting of the clamping blocks. I decided to use the 'bending method' on the large inboard tabs only and modified a small riblet I made (and rejected) for the inboard edge of the Elevator. It fit perfectly in the outboard end of the trim tab with a minor modification for length.
