I’m driving only blind rivets, which means they’re inserted into a hole, then pulled into shape using a tool on one side of the rivets — commonly called “pop” rivets. On the way to looking up something else, this excellent old-school instructional showed up on how to drive countersunk rivets, that is, rivets that are flush with the skin of the airplane, eliminating a source of drag at high speed. Watching it, I wonder how any homebuilder ever had the time to countersink their rivets.

I also picked up one of these today. I’m having some discomfort from squeezing the cleco tool. https://www.youtube.com/watch?v=DaAEu2rnfRw
Jim Butler did with his award winning Midget Mustang.
He was a homebuilding superstar.
Weirdly Dean I actually just watched this video recently as well… I am surprised it doesn’t end with “next lets review the 17 different fundamental types of bucking bars and their specific uses and applications…”
I think that’s in Season 2.
