Finished fabricating the F-638 seat back brace - 2.5 hours

I need to drill the holes in the F-638 seat back brace. The plans call for 2 1/4" holes but I don't have that size of hole saw. I do have a 2" hole saw that cuts holes a tad larger....more like 2 1/8". So for me this is good enough. Using scrap MDF as a backer plate. I located the center of the holes and drilled to #40 and clecoed the brace to the MDF. 

 I now have a stable platform to drill the large 2" holes and not have to worry about the pilot bit 'walking'. 

All holes are easily drilled. Next I drew out the dimensions on the ends of the seat brace and cut them according to the plans. Used aviation snips for a rough-cut and then used the sanding station to finish cuts up to the line. Final edge cleaning by 3M wheel.
