On my 22mm coaxail i have hot glue piston it's okay, but opens very slowly. I don't have enough epoxy to make an epoxy piston so does anyone have an idea of what i could make it from?
I'll put it up in the showcase soon and with a sneek peek of my 22mm piston in a tee

-Tighter piston fit
-Lighter piston
-Better pilot valve
When casting an epoxy piston it shouldnt be solid epoxy. You should look into making it hollow or with a foam core. Its lighter, and saves you epoxy.
