Continuing the fun started in this past thread, I've got a new pair of longerons bent and fit to the already-drilled skins/bulkheads. Preparing to re-drill them. Some problematic areas will be where I originally drilled through several pieces in a stack. Now I need to drill through just the longeron while somehow ensuring alignment with the other existing holes. For example, skin to longeron to engine mount.
Illustration:
Any good techniques or tips on how to accomplish this correctly, through 1/8" thick metal? I know from experience that, no matter how well things are clamped and how straight I drill, if I just match drill through one of the existing holes, the bit will usually come out slightly misaligned with the rear hole and/or make it oblong.
