I had the same problem until I finally figured out the tool that one of thelocal EAA'ers was trying to describe. Imagine a C-clamp body with the screwremoved and a hole drilled all the way from the threaded part through theseat on the bottom. Any two rods placed in these holes have to be aligned.Match drill the metal fittings, then sandwich the fittings over the spar (orwhatever), then place the C-fixture over the sandwich. Use a proper sizebolt to align one end of the C-fixture with the hole in one side of thefitting, then drill through the other. Your drill will eventually push thebolt out of the other side and the hole will be aligned perfectly.I've probably welded up half a dozen of these devices in various sizes andshapes. I used square tubing from Home Depot for the body, and a piece ofstructural tubing for the drill bushing. Cut the center part out afterwelding to ensure that it stays aligned. But come to think of it, youprobably could make one out of a C-clamp...Gene Hubbardin San Diego, working on engine controls and trying to figure out how tomake a cub-style cowling.-----Original Message-----
