i did my wrist like this, 1 layer resin outside, 1 layer inside, then used thin fiberglass mat for the inside, then added another layer for the outside of the part, and for my blades i could not resin the inside , so them took 4 layers resin without mat, pretty strong btw, hope this help
Great!! I have exactly what you are looking! this is really a great coincidence because I was trying to add a post here in the forum and was not getting, then I found your question. I found a complete tutorial with links to download the program and also other bios papekura shared. ALL I put on my blog not to take up space here, photos, links and very cool work!
