OK, I thought I understood the difference between match drilling and final drilling, but page 15-4 has me doubting that. I thought match drilling meant one piece of metal had a hole and the other didn't, so you use the established hole as a guide in drilling; final drilling meant both pieces of metal had holes but the holes needed to be enlarged to final size.
If I have the definitions correct, step one calls for match drilling where all the parts already have holes in all the pieces.
What am I missing?
Thanks.
