SpudFiles

Hi everyone, this is my first post on spud files. Im no stranger to spuding though. I hope to post some pictures of my previous works soon. I was planning on building a Piston Valve Cannon. I was just wondering if anyone has heard of or used a Buna-N Piston cup seal. I was planning to use it to make my piston. It looks like a better alternative to a rubber washer. Thanks and let me know what you guys think.

I know of one at any rate. Worked quite well IMO.

Very nice work^^^^^^^
