Thanks very much for the replies guys (sorry for the delay). BrundelFly: I think I have been letting it harden between layers. I tried to get the second coat on as soon as the first one had stopped being tacky, not whilst it was tacky. I will investigate the thixo additive for PU resin. It's...

Hi all, I'm trying to slush-cast a few parts of a Ghostbusters proton pack in polyurethane using RTV silicone moulds, but I'm having trouble with the built-up layers of PU resin not adhering to one another. Below is the setup I'm using for another part of the proton pack. I think...

Hi all, I'm in the process of making another couple of Portal guns, following pretty much the same process as I did for this one. This time, however, my intention is to make moulds of the front grip and rear shell using RTV silicone then cast the two components for each gun using...

Thanks mate! I'm really happy how it turned out. Just wish I had one for my shelf now!

Hi guys, Just thought I'd share with you my scratch-built Portal Gun. I based my design on the Portal Gun created by Harrison Krix of Volpin Props. Without his detailed photos and descriptions I would have been completely lost. All the images and details of the build are...
