Because of its strength and the ease with which it can be formed, I chose fiberglass as the medium for the helmet shell.\u00a0 I have worked with fiberglass in the past, but only as a tool to repair an existing structure.\u00a0 I’ve never tried to fabricate with it.\u00a0 So, I had a pretty good grip on the basics, but not a lot of practical knowledge.\u00a0 That in mind, I decided to try some small-scale tests:<\/p>\n

<\/p>\n

On the left, I had some plaster that had hardened inside a water bottle.\u00a0 I covered it with polyurethane and using that as a test plug, I went ahead and wrapped the fiberglass around it.\u00a0 The right side is a water bottle that I wrapped in fiberglass with no prep. When it all dried, the fiberglass was pretty well stuck to the plaster plug as well as to the bottle.\u00a0 I expected the bottle’s results, but the plaster was disappointing.<\/p>\n

New game plan was to cover the plug in many layers of poly and then wax it heavily, so that was the next step.<\/p>\n

<\/p>\n

Once the plug was sealed and waxed, I started putting layers of fiberglass on.\u00a0 I would let a layer dry and then put on another until there were at least 4 layers across the whole helmet.\u00a0 Once that dried and cured, I attempted to pull the helmet from the plug.<\/p>\n

<\/p>\n

That’s the plug after the shell was removed.\u00a0 Total disaster.\u00a0 The fiberglass didn’t want to release, even with the sealer and the wax so I was stuck using a hammer and chisel to break up the plaster and the foam and dig it out of the shell.<\/p>\n","protected":false},"excerpt":{"rendered":"
