Elevators - Joining Skins

Took a few days off from building, but went full steam ahead today and made a lot of progress! We started with rolling the opposite skin (L-bottom and R-top) over their respective assemblies. This was done in a similar fashion to how we joined the rudder skins, although unfortunately we didn't take pictures of the process this time. When complete, we had the elevator skins joined within their internal rib structure, but the skins were not riveted to the spars yet. In order to continue, a special bucking bar had to be made per the plans:





Jumping at any excuse to make this many sparks, Mike makes a similar bucking bar to the one called out in step 9-12.3 out of raw steel stock.




Hot off the press, the new bucking bar is put to work inside the confines of the R elevator skin.


After riveting the rear spar to the skins (except for the areas called out to skip in the plans to accomodate the trim tab hinges) the front spar was riveted in:


Now we're starting to have something that looks like an elevator!!
