1'' Piston Hybrid {WIP}

Unread postAuthor: Crna Legija » Sat Apr 07, 2012 3:16 am

This is just a update since posting this, its getting there just need a few more fitting and a good pressure gauge for the meter, for the time being ill use a camera flash dumped in a car ignition coil for ignition but would like something a bit smaller later on.
