This is one my friend is working on thought you guys might like it. I know there are several ways of strengthening pepakura weapons but I was wondering if any of you guys had tried any and their results? Only ask because the torque bow I'm currently doing might've been a fail. I split it and fiberglassed the inside, but I got some warpage going on. I think the next one I will try the smooth cast plastic. Any advice and enjoy.
