I just finished cutting the instrument panel for my Cub 2 weeks ago. See bottom of<http://jscott.comlu.com/Cub/final_assembly/Final_Assembly.html> I used .063 2024 T3 for the panel, although 6061 T4 probably would have bee preferable for the task, but didn't have it on hand at the time. I used a 2 1/4" Greenlee punch for the small holes, and a fly cutter for the 3 1/8" holes. The key to using the fly cutter is to do it on a mill at a very slow speed and light pressure with some lubricant and make sure the panel is properly clamped down. A drill press isn't going to go slow enough for the task. The fly cutter made nice clean holes that worked out very nicely. For my KR, I built a plywood panel, so only needed hole saws to make the instrument holes. Pictures from when I built it are at <http://jscott.comlu.com/KR/first%20flight/N1213W%20First%20Flight.html> -Jeff ScottN1213W ---------- Original Message ----------
After a nerve racked morning with a fly cutter I have determined that I am probably not going the be able to cut the instrument holes. Another option is a Greenlee punch but those are quite expensive unless someone has one to loan. With all that said I am thinking that I want to mark up a piece of .125 aluminum sheet and send it off to someone to laser cut. Any suggestion on who could do that for me?
