I ordered the little close quarters wedge from Cleaveland Aircraft Tools last weekend, but I’m still waiting for it to arrive. Meanwhile, I thought I’d try making a temporary one out of plastic. Pretty quick work to design the part in Fusion 360 and then send it to my 3D printer.
Looks great, and I bet it’s even pretty darn close to the dimensions of the metal one!
… but it didn’t work so well, it was easily crushed by the force of the rivet puller.
I managed to get most of the tough-to-reach rivets anyway without this aid. My manual rivet puller has an adjustable head, so I was able to get into the tight spaces.
