RE: cuttin a hole in a foam wing
Hi ! I use an aluminiumtube that i have filed sawtoths at the end. I make a guide of plywood and just drill the hole by hand.The guide needs to align the tube in both angles. a boxlike thing with two holes in opposite walls. I simply, use woodscrews to hold i to the core.Not sure if this is understandable, i have drawings i made earlier. will try to find them.Jonas
