Starting this thread to keep track of what I’m doing. Shamelessly copying @whitepony with his Awesome vanguard build which in my eyes is still the best build I have seen. Trying my hand at vacuum bagging with carbon fibre - I have borrowed a vacuum pump from a refridgeration mechanic friend of mine. My first vacuum bagging attempt I used the ghetto bagging method with a vacuum cleaner. It turned out OK but I didn’t use enough epoxy, and my mold was too small. I used plaster of paris for my mold which I cast from one of @Dunkirk s enclosures original post hereSecond attempt I used a single stage vacuum pump, west systems 5:1 epoxy resin, which I think gives too much of an opaque finish a 2:1 would be better but it’s what I have, 1 layer fibreglass, 1 layer normal carbon cloth 2 layers carbon twill. I used equal weight of epoxy to cloth which turned out a little dry. The roller would have soaked up too much I guess so I didn’t actually get the correct weight ratio on the cloth.
The bag I used is a roarockit bag which I cut so I could lay the cloth then fold the bag over and tacky tape the bag down. Vacuum pump draws really strong ! Cracked my mold which has left a nasty mark through my enclosure.
