OK. Over the weekend I was able to fill in the undercuts with silicone, cut my registration keys, build the plastic flange out and make the fiberglass mother mold front half. There are a few minor things I need to correct with the silicone but overall it turned out very well I think for my first attempt at this. It had been awhile since I actually saw the inside of the helmet... good to see it again. The important thing is that in the process I learned some things along the way. One of the main things is that I need to use resin Jelly to fill in the areas around the registration keys and along the flange
prior to laying the fiberglass mat. I thought I could make it work without it and ended up having to fill in some air pockets in the fiberglass after the fact. Here are some more pics.
Undercuts filled in, registration keys cut, plastic flange built up where needed and ready for the fiberglass mother mold to be added. I applied 5 coats of Caranuba paste wax to the plastic flange and then sprayed the whole thing with Mann Ease Release 200.
Building up the fiberglass shell...
Trimmed the edge with a Dremel cut-off disc and gave it a quick coat of primer...then breaking away the plastic flange.
The flange removed...
The clay removed...
The lenses removed...
A close up of the flange with the resin Jelly added...
I need to clean up the flange, clean the clay residue from the silicone and correct a few issues with the silicone but this is basically where it is at, ready to start building up silicone on the inside.
I know this is a big update but there was a lot that went on in a relatively short amount of time. I am excited about the progress so far and anxious to get the inside done. I may need to order some more silicone to complete the inside which could push out a first pull an additional week or so. If it does then oh well...I am not going to short-gut this. I also need to order some plastic funnels for pouring the resin when it is time and oh by the way, I got the laser diodes I ordered. YAY!!!
That's all for now,
Steve
