how can I make the diamond part. I got that armor off of ebay, with the diamond part blank. I tryed to paint it, but I screwed up. :confused How can I carve the middle part?
Is it plastic? Fiberglass? How thick?
If it's plastic, you could probably just cut out a rectangle and glue a thin piece onto the back, simulating the depression in the middle.
Or you could cut a new diamond out of a 1/4 inch sheet of marine plywood or the like, then you could dremel or router out the rectangle-that is if you want to go to all that trouble...
