Oops! We forgot to dimple the HS-801 skins before priming the insides. Not a huge problem, as the SEM primer turned out to be very resilient and nearly unfazed by the dimpling process.

The squeezer yoke bench mount and Cleaveland Main Squeeze made setting the -4 rivets a breeze — or, at least, as breezy as manual squeezing can get.

Van’s rivet callouts for this section are just a hair too short, but the instructions are adamant that you stick with what’s called for, so we ended up with shop heads that were just a bit too small, but adequate.

We had trouble getting the squeezer yoke over the HS-814 angle, so we ended up breaking out the gun and bucking bar. Yep, we had to drill out a couple of rivets as a result.

Things look pretty scratched up, but close enough for government work. (I hope.)
