So remember when I said I should've resined the inside of the helmet? I really should have.
At this point in the build, I was cutting the tubing for the face plate. I sat the helmet down on a sawhorse and it promptly slid off and hit the floor, cracking right up the chin.
Even at this point I thought I'd be able to make it once I got the tubing and padding on. I fixed it with a sandable 2-part epoxy.
