Still work to be done, but things are coming together. 

This is where I'm at currently

I updated the work diagram:

Completed parts

Chin light, complete with separate housing and lens

Standard M4 nut with integrated washer for the Wedge plate, fastened with an M4 allen bolt from the inside.

Flanged and bent conduit completed, this is one of the most work intensive parts on the entire ear piece

Another view angle of the conduit
