My first significant riveting was to assemble the read spar. I used my squeezer to set these rivets that attach the bars to the channels. Then the hinge brakets were riveted to the spar. Next I bolted the cnter bearing to the bar at 20 in-lb of torque. This was my first use of my torque wrench and I learned how to use it properly by not using it properly on the first bolt. I broke it off and put in a replacement I ordered from Van's.
