hey guys
so I'm attempting to make my a costume for the first time. as part of the costume, I want to have a clear samurai sword that lights up. I bought a replica sword with a removable blade, so I can use the sheath and the handle. I already have a good idea of how to wire up the lights. the only problem is I'm not exactly sure how to cast the blade. the blade is roughly 0.15" thick, and 37" long. I was originally thinking I could do a single pour mold with a sort of a silicone putty and clear resin. however after some research and watching some tutorials I see a lot of people casting blades with a 2 piece silicone rubber mold. only problem I see with doing the cast this way is because the blade is so thin, it might be really hard to make it exactly the same dimensions.
would anyone be able to help and give some pointers on molding/casting the blade?
