Fattie piston

I am planning to do a couple different fatties for the bowl and was hoping to get a couple different designs for a fattie piston along with a couple different stuffin y'all use. I've made a couple fatties so far but never used a piston and would like to give it a go. Anyone who knows me, knows that I'm not one for simplicity, I like cool toys. So... if anyone has a Tecumseh powered fatty piston I would love to see it. If there aren't any Tecumseh powered fatty pistons out there I wouldn't mind seeing a manual fatty piston. Thanks.

awesome thanks
