The no-hole yoke from Avery Tools arrived today. This yoke only uses one die for squeezing rivets and uses the flat end of the yoke itself for the other squeezing surface. This allows it to access very narrow areas where only pulled rivets could be used otherwise. I actually made it a little narrower by grinding it down slightly with the bench grinder. Worked like a charm on the right elevator ribs.
I also bought some plastic boots to reduce smileys on round head rivets, hopefully they help as I still struggle with that for some reason.
