i currently have a robart incidence meter and it will not fit my wing the angle pieces on each end are too small and will not fit over the trailing edge. Does anyone make one that will fit on thick wings or does robart make some pieces that i can purchase? Or is thier anything that i can make?

Those pieces are designed to center over the chord line, and don't necessarily have to fit the wing edge into the corner of the "V". As long as they hold the arm of the meter in place, they should center over the chord line of the wing, which is what you want to measure for incidence anyway. You mention that it won't fit the TRAILING edge of your wing? Seems like if anything, it wouldn't fit the LEADING edge, since it's thicker. How big a plane are you checking?

Below are some pictures. Its an OMP Hybrid Edge 92 span.
By the way what i did was glued some 1/8 lite ply to the angled pieces so they would extend past the edge of the trailing edge.

I guess what you wanted to do was install the meter without the ailerons on place. I can see how it wouldn't fit the T.E. now. I would have left the ailerons on and locked them in neutral with a clamp at the hinge line, and attached the meter to the T.E. of the aileron. But what you did should be fine. Good plan.

Nice looking build going, BTW.
