35cm of snow on the way

I'm in the planning stage of a build, and have a quick piston valve question. I want to keep the piston as light as possible, but want it to work properly. Would this work?

you should build an EMP generator. or you can take a look at " electronic gadgets for the evil genius " books, there are two of them. The books teach how to make so many things: anti-gravity projects, electro kinetic guns, mass accelerators, all types of lasers, tesla coils, nightvison, and more. I ...
