Yeah, I need to get cracking on this thing again. I'm in the middle of an ammo belt run, but should be able to clear up my weekend to work on the helmet.
I got a new earcap from BobaMaker, and it ROCKS! I will still have to modify the earcap 'seat', as the BM cap is about an 1/8" taller than the seat. And as much as I hate to use it, I'll probably have to use Bondo to build up the seat a bit. I'll post progress pics when I get to that step.
Next steps: mandible cross-bar, fiberglassing the interior, and finishing the earcap prep.
