How should I install a throwing peg in the Monarch Fuselage?

Hi Don, I have a quick question for you. I'm building the older Monarch 94C (My first Monarch) and was just wondering about the finger hole. I'd like to use a peg instead, like the Chrysalis.

How should I install this in the Monarch Fuselage?

From Don Stackhouse :

I'd recommend the same thing we use for the 'C' and 'D' Monarchs. We use a 1/8" thick by 1/2" wide spruce or birch ply finger peg, 2.75" long seems to be about right. Cut 2 windows in the fuselage sides just above the lower carbon longerons, 1/2" chord x 1/8" high, with the trailing edge of the windows at 3" aft of the leading edge bulkhead. Congratulations, your Monarch is now "windows compatible".

Slip the peg through the windows, with equal amounts sticking out either side. Use epoxy and fiberglass tape or chopped fibers to reinforce the area around the joints between the peg and the windows on the inside of the fuselage. Some microballoons in the mix will also help keep the weight down.

Taper the leading edges of the pegs outside of the fuselage so that the pegs are about 1/8" wide at the tip. Scallop the trailing edges a little to fit your fingers. Laminate some 1/8" to 1/4" balsa on top of the pegs to get a little more thickness at the trailing edge, for a more comfortable finger rest surface. Carve the balsa to match the profile of the pegs, then sand an airfoil shape into the leading edges. Slightly round the trailing edges till it feels right for your fingers. When you're done the pegs should look like little delta wings with blunt, scalloped trailing edges.
