Spar Web Doubler Pre-Mounting

Posted on November 26, 2014 at 7:14pm 1 Comment

Shifted focus back to the spar web doubler yesterday and today. Have pre-mounted to the spar and cut and pre-mounted the strut angle. Thanks to Timothy Aanerud for his advice on the strut angle cuts and photos of the entire assembly! I have to admit his strut angles look better than mine!

Wing Spar Photos

Could someone post front and rear views of their completed wing spars? I am particularly interested in close-ups where the Spar Web Doubler and Spar Root Doubler are mounted. Thanks in advance.

Spar Root Doubler Mounting

Yesterday, I shifted attention to one end of the spar. I drilled out and temporarily mounted the spar root doubler assembly that I had made some time back but had put aside.

Spar Drilling

Yesterday, I finished drilling the remaining spar pilot holes and then followed up by drilling out to #21. I will put an angle on the Spar Web Doubler when I go to our chapter meeting next Saturday (my bending brake cannot handle .063" metal). Will pre-mount it later in the day.
