OK, so let me repeat this, you use ply @ dowel hole locations, then you use 2 shorter dowel rods @ ea, hole. Thanks for the tip about the rubber bands, had been told to remove and dis-card after a flying day for the same thing you have pointed out. As always, I value your info and advice on these little tid-bits you have learned.

Something you might want to consider, on one of my Eagle 2's, on the rear holddown dowel, I epoxied 3/4" square of 1/4" of AC ply
over the 1/4" dowel hole on inside of each side. Then drilled a 1/4" hole through both AC ply for a pair of 1" long dowels. That way the dowel will not interfer with the throw of the Aileron control horns.
A word of caution about the rubber bands. When they get glow fuel on them, they become very soft and lose their strength over a short time.
