Bike Helmet Boom Mic: Housing

The last time around, this involved silver soldering the boom wire directly to the mic housing. This time, I filed a fishmouth in the smaller tube and epoxied it to the tube that’ll hold the mic capsule:

The smaller tube is a loose slip fit for #10 copper wire, but that’s really too heavy for the boom. I’ll probably nestle¬†#12 wire inside another tube and epoxy that whole affair¬†in place.

The mic capsule tube needs a rounded notch filed in one end to accommodate the wire.
