Making doublers and templates for the center section - 7 hours

I will need to make a spacer for the aileron trim at some point. Since I don't have 0.063" material I decided to make a template out of scrap. Once I can get some thicker material in I can make the spacer. It takes only a few minutes to make it.



Next, I had cut some strips out of 0.025" scrap to make a doubler for the F-716 seat ribs as per vans suggestion (See the July 7,19 blog for details). Fortunately I have a good bit of 0.025" scrap so I went to work on the strips. I had decided to make full strip doublers for a number of reasons. Not all of the AN3 bolt holes are in the best location so I fell more comfortable making doublers for all the flanges. I don't think it will add a bunch of weight, but it will add safety. Next, a full size doubler will be fairly quick and easy to make.

Lots of time spent making, cutting on the bandsaw, sanding, then edge deburring.

Minimum edge distances are marked on the strips and then numbered to match the ribs. Here is pics of all of them so there is a good record of whats there. The doublers are going to cover up the flanges.
 



The holes for the AN3 bolts were drilled.

I then marked the overhang on the both the top and bottom of the doublers. Trimmed then and rounded the corners on the 3M wheel.
Next I notched the holes for future wiring.
