This page shows one of my developments that i did, this one is on a plannishing hammer.

You all know that a plannishing hammer normally is a kinde rivet gun that runs on air.

I don't like to use air so i desided that there must be a way to make a plannishng hammer that is mechanical.

I came up with an idea and i built it and after a few bugs in the first week it runs now for almost 2 year without problems.
