Proton Pack

Here are the progress shots of my proton pack and particle thrower. Ive decided to start building the gun first, made from PVC. Parts have been cut and then sanded with coarse grit grinding discs, then a finishing sand with wet and dry paper. The reason im sanding it back a bit is cause I want the whole pack to have that weathered look once its painted. Always welcome feedback, and I'll try to post as many photos as possible to help anyone else who is building one also. Cheers!
