[UPDATE]
SO, I decided to postpone doing the bondo-ing on the top until I figured out what to I really wanted to do with the 'Top Nuts'. Originally I wanted to make them into vents, but I've always felt a bit bummed about the lack of lights this helmet had. So. I took some creative license, and am working on incorporating lighting into the nuts while still using the vent idea, but that will be revealed later!
In preparation for that, I needed to make some shell modifications to fit my idea. So I made some templates to mark holes and cuts I needed to make
I began to core out the holes with a hole saw, which was going well until this happened...
The other two fared better, but still took some damage...
This process revealed a serious flaw in the shell, and my workmanship... I didn't get ALL of the bubbles filled up. Use this as a lesson kids!
FILL THOSE BUBBLES!!!
Oh well, nothing a little bondo can't fix!
Now to my lighting idea!
I have access to a CNC machine, and 3D printer if I need it, so I decided to design a 'Nut' using reference photos that would be made of acrylic.
My thought is to paint it with that 'Krylon Looking Glass' stuff, then cover that in black (Add some reflectivity, and light intensity), then sand off the top of the two rings to expose the acrylic underneath. I was going to use a fine grit to give it that frosted-but-not-gouged look, but since I'm going to cover the helmet with a matte clear coat, I'm not too worried about that. Then obviously stick an LED underneath. This isn't the only place I'll be using lights, but that's a story for another time
As for the vent, the little cutout in front of the circle will be the venting portion. I'm thinking of using some black fabric, or screen to allow air passage, but not allow sight into the helmet.
More to come!!
