Calil,
thanks.
==================
Wing LE.
Ripped some large stock balsa into a LE for the wing.
I actually thought I could drill out the holes, perfectly spaced, and place the LE over the guns: That delusion was quickly dispelled and I just cut each LE piece for each gun and glued it in place. Will be much easier to fill in LE cuts versus enlarged gun holes. After removing the screwed in guns, started to plane down the LE to conform to the wing.
Some local neighborhood kids came over to 'help'.
