Getting the Trigger Switch in, how it's Done.
The Tips of the SW are cut, wires are soldered and the area coated with Lepage Professional Epoxy. A small hole is drilled near the rear of the SW hole for the wires. The switch is partially in the aluminum tube.
A cutout of 1/2" in the aluminum allows room for the SW. Nicksdads trigger knob's hole is too big, fill it with JB Weld and drill for the SW actuator size exact, also drill in 1/8" in with a drill bigger than the SW Dia. Don't look at the original, it has a larger hole probably for another SW.
Sorry about the photo, the SW does not protrude much past the slot.
To get the tubes straight is another priority. I compared the alignment to the ivory replica. You can take measurements & photos before cutting of the resin handle. I put some 5 Min Epoxy and get it aligned as it sets.
For the SW-Knob, make sure the knob is set just inside the recess as shown. You do this by trial fitting and checking the actuation.
Fill the SW cutout with JB Weld. After Dry, Fill in the area around the Tube Tops, I used BBs close to the tube for weight a JB Weld saving.
