Finished LH Lens. Left a greater margin at perimeter, approx 1/2" instead of 1/4". Fits great. Sanded edges to smooth finish using 400 grit, including rounding. Very surprised as I was finishing up to see 2 very small cracks starting at edge - so quickly stop drilled and chamfered. I had noticed the Backing Plates had moderate "bow" (whereas those on RH Lens sat flat onto Lens), so maybe once tightened they may have induced stress along edges. RATS ! Hoping stop drilling will prevent major cracks from developing - or I'll have a "do over" in future. Otherwise, I'm "done" with Wings. Ta Dah ! Time to exchange the QB Fuselage from basement with Wings.
I left the tape on as I installed this time. Removed tape after removing Lens. |
@#$%&! ( i.e. Drat ! ) Couple cracks started soon after I re-inserted screws to hold backing plates while double sided tape "set". Maybe stop drilling will save the Lens |
