Yaa, I'm doing it under my A&Ps supervision. Though he wants me to
drill
all the way through for some reason, says that is the way he was
taught. No
biggie. After doing 250 rivets tonight I've found either method works
just
fine :) Am using a small punch vs the wrong end of a #30 bit though
the bit
is a good idea and I'll have to use it when I do other sizes since I
won't
have the exact size of punch.
Thanks for the info!
Joa
