Went after the wingtip being too thick tonight. It was bout a 1/4 inch too
thick.

Slit the wingtip bout 16 inches, slit the rear closeout bout 22 inches. Filed
till when squozen it looked nice. Drilled a few holes on either side of the
closeout and safety wired with .025 SS wire. Very controllable the gap. Did the
same with the tip.

Very little stress and was able to adjust to get a fairly uniform gap with
aileron.

I tried slitting only bout 10 inches and there was a bunch of spring action that
I thought would be hard to get things where you wanted them. Also the airfoil
with the longer slit seems happier.

Left the safety wire on the closeout, just cut short and folded it flat, put a
dab of flox on top of it.

Did a 2 ply BID 2 inch wide on plastic. Filled the mini gap with some flox and
put 2 BID on both sides of closeout, and 2 BID on inside of Tip.

I am going to install the closeouts backwards so it is flat on the edge.
