I tried to search, I know weíve been here before, canít find it, canít remember for sure.
Andy, Michelle and others know this one.
Is this correct:
Drill out old rivets with #30 bit. Then open hole with #21 and install new rivet?
For brand new rivet installation what size pilot hole should be drilled before #21?
There 3 sizes of drill bits that are used for Airstream construction and repair.
For buck tivets which are 1/8 inch, use a #30.
For olympic rivets which are 5/32 inch, use a #21.
For the underbelly rivets which are 3/16 inch, use a #11.
Our web site has those three sizes in a kit.
