Getting started on the wing jigs
It's been a long time since I have worked on the airplane kit. I have gotten the front yard in, wrecked my Red VFR you saw below and repaired it, wrecked my truck, and blown up the engine in my wife's Passat since I've written last. It's been a long and painful summer/fall. However, we are putting that all behind us and moving on. I am starting back up on the kit and have purchased some steel to make a wing jig. Most people use wood but I opted out of that since my garage ceilings are so tall. Wood also warps and twists when it dries out. It's also hard to find a straight piece of wood anymore at the lumber store. Steel is much better and won't warp. Since I work in a mill, I have found some scrap and bought it and will be pieceing it together. The jig will mount on the floor at each end of the spar with four concrete bolts. I will be able to adjust the plumb for each stand as well as the arms the spars lay on. Once it's set it will be rock solid and I will use my lasar plumb line to make sure there is no twist in the structure. I can also use the lasar to align the chord line of the ailerons with the chord line of the wings. It beats trying to measure and transfer this stuff. I had to move my ailerons on the last airplane because I did not get it right the first time and it flew crooked. Once I bought new brackets and redrilled them, it flew hands off. Leasons learned. Look for some pictures later of the jig building process. I might even build a steel jig for the fuselage when the time comes.
