Made some tunnel reinforcements the other day.. went to the Doo shop and was looking for some beefy rivets. Purchased some rivets used on the bulkhead, however, when I went to pop them they wouldn't fit my air riveter. Turns out the nails are 9/64 as opposed to 1/8 as used on a normal 3/16 rivet. Any ideas where I can find a "nose" piece for my riveter to fit the larger nails?
