drilling perpendicular pylon holes in wings?

I plan on adding some leftover WWII unguided missiles to my what-if corsair, but I am boggled by how I should drill the holes. for the correct spacing between the missiles, I can always use an index car template, but how would I drill perpendicular holes? Especially in the bent wings of a CORSAIR. lining them up by eye-balling is going to drive me nuts. All my hairs fell out when I was trying to get the hor stabs to go in all perfect… imagine 8 little missiles… AAAAGHH

I think you’ll find that the rocket launchers were actually attached at right angles to the ground - not the lower wing surface.
This isn’t a very clear picture, but you can get the idea:

So just drill your holes, attach the launcher rails, and adjust them so they’re perpendicular with the ground. Easy.

yes that was what I meant [:)] I guess I didn’t explain it clearly enough.

Is it really that easy of an eyeballing job?

Mate,
If you use a slow-ish setting type of glue, attach one of the launcher rails, set the plane on its wheels, and using something that has a 90 degree corner (a draftsman’s square, engineers square, carpenter’s square, a book - anything, really) and place it on the desk in front of the plane, sight along the spine of the book (if that’s what you’re using), you’ll easily be able to see if the launcher rail is at right angles to the ground.
Easy as falling out of a tree.
Cheers, brother!
