Does any one have any suggestions on preventing misalignment of holes when match drilling pre-punched components? I have found that even when I cleco every other hole, sometimes the holes that I am drilling may be misaligned slightly, resulting in a slightly oblong hole on the bottom that is out of the mil-spec diameters.
One example was when drilling the reinforcing bars into the rear spar of the HS. I have tried both reaming and drilling with my 3000 rpm drill. On these long components I find that I end up with at least a few holes through the thicker component that are enlarged slightly, or an oblong hole on the bottom component (i.e. thinner spar) once I flip it over.
Also there are location where it is almost impossible to secure the two components with a clamp due to the angle or a flange in the way.
Thanks!
