REFLECTOR: Adjusting wing incidence

[Lou Stedman]

The easiest method was taught to me by Ken. Take a tong depressor file out a concave at the end to fit your washer. Then put on a drop of super glue. It will hold the washer until you get into place. Works great

All, 
After attaching my lower strake and comparing the angle between the strake and wing, things didn't look right.

After going back and verifying the right measurements off the spar to get the strake aligned properly (they were correct) I remeasured the incidence of the wings.  With the firewall 90 degrees, the right wing was off level about 1.1 degrees.  The left wing about the same.  

Though not a tragedy, I'm puzzled.  This seems like a lot to be off with the wings bolted directly to the spar.  Is this common?

At any rate, I understand adjustments can be made by shimming out the wing attach bolts.  I was wondering how folks are doing this?  Washers seem the most obvious, but maneuvering them in there might be tricky.  Was wondering if anybody has fabricated a bushing out of aluminum tubing or something similar to act as a stand-off, whether that's safe and if so, what material should be used (aluminum, steel, ???) or should I stick with washers?

TIA,
Peter
