I laid out a bunch of lines on the aluminum and cut out the shape on the band saw. Cleaned things up with the wheel and lots of filing then used my hand seamers from Avery to make the bends. That's why there is a relief cut in the middle of the shelf as the hand seamers are only 3.5" wide so I bent the front support in two separate bends. The shelf has a 7 degree downward tilt to match the backward tilt of the panel. I leveled the fuselage on the stand across the door sills (which levels the panel) using a precise carpenters level. I drilled only one attach hole through the bracket to allow me to pivot the bracket up/down until it was parallel with the fuse then drilled another attach hole, clecoed, then drilled the rest. The tilt of the bracket was within 1 to 2 degrees of the panel. I used some plastic nylon washers to make them closer. All together took several hours on a couple of different days. -Ben MauleDriver wrote: > Real nice bracket - I'm afraid I can't easily produce something quite > like that but it's in a great location.
