Well, I spent a good part of nearly two months 'looking' at the trim tab. I was deathly afraid of bending those tabs. I designed and built 4 different 'bending blocks', none of which was any good. I was dreading this job. Not to loose track of things, I just went on by working on the fuselage. About once a week I would re-visit the trim tab. That would amount to staring at it for 30-60 minutes then moving on. The other local -8 builder had done his with riblets. So yesterday I said to myself 'self, why don't you try fabricating riblets'. So I did. I went to Harbor Freight and bought one of their cheep $20 bending brakes. It is a POS but it works if you don't mind all the time it takes to set up a single bend. I cut the blanks out of .016 scrap that came in one of the bundles. The outboard rib took 2 tries and the inboard took 3 tries, but after 2.5 hours of not knowing what I was doing I had riblets that fit and looked good. I then did the brave move of cutting off the tabs. I then marked, punched and drilled the skin with the riblets clamped in place. I will dimple them when that time comes and use 426AD3-3's to hold them in place.
