It has taken a while with other projects, but here we go. I took my manner eh1 stock and made a good fiberglass mold. I made sure to sand it to perfect the edges and polish it with a red scotchbrite wheel. A couple coats of paste wax for release and it was ready for layups.
I used 2 layers of cf weave then vacuum bagged in each mold half. After they were fully dry, I laid down 3 layers of unidirectional cf inside, put the two halves together with cf overhanging inside to join. Once bolted together, I poured in some expansion foam thru a hole in the top of the mold (just above the trigger). The stuff expands 30x its liquid volume and you have about 45 seconds to mix and get it in there. I placed the mold in a heated closet at 80f and let it expand for an hour (only takes 5 minutes). Decided to leave it in another 3 hours for the epoxy to cure enouh to pop out of the mold and here she is.
Obviously needs the edges cleaned, but at 22.4oz and strong as can be, I am pretty happy. Next is to clean, trim, lightly sand, inlet and test. Not bad for the first full try.
