Brief Description: Strut 2
|
|
I removed the wings and struts. Previously, the left strut had developed a crack during the compression process. Bob Barrows graciously provided a replacement strut and Mark Goldberg provided a new set of wing strut fittings at cost. I compressed the strut again using the vise. The Avipro manual recommends a 1-5/16 inch spacer (3/16 inch shorter than the fitting width, which is 1.5 inches), but that's not enough. It took about 1.20 inches on one end so I made a spacer at that size and it took slightly less than that on the other end, about 1.21 inches. I match drilled the left strut, rather than going through the whole diehedral-fluid level business. I clamped the two struts together, so that the inner flats were parallel and the two struts were at the same height when resting on the scaffold tubing. I drilled through the old strut, into the new strut through one side only, and bolted each hole when accomplished. Once all 8 holes were drilled, I put the fittings into the new strut and drilled through to the other side. I put in 8 each AN4-23A bolts into the new strut, and torqued them, and accomplished the same in the right strut, which had been waiting for an Aircraft Spurce delivery.
