On page 09-18 Step 5, how the heck is one meant to buck those rivets along the rear spar?!? I have the special bucking bar, but that's intended to utilize leverage (when doing the second skin) unavailable with the assembly clamped to the edge of the workbench for this step per the plans. None of my many other bucking bars fit suitably inside the rear spar. Is it a two-person job with the special bar? It'll take two hands on that bar and I'm short a third hand to run the rivet gun...
What am I missing?
I just arrived on page 9-20, figure 1 where that special bucking bar comes in. I have the special bucking bar, but that looks like a wonderful way to screw up my elevator. The blurb above the callouts for the special bucking bar indicates that an MK-319-BS is acceptable for solid rivets anywhere this bucking bar is to be used.
My question: Has anyone else tried using Cherry's in the rear elevator spar? In the hinge portion of the left rear spar, I actually riveted it vertically, as the thought of driving down into the spar directly gave me pause.
I am leaning towards using Cherry's rather that the MK-319-BS's.
I welcome feedback from the group. THanks!
