Got it Thanks ogre
I cut a piece of steel and removed the surface rust with this.
It doesn't spark so no steel removed and it makes it shinny.

Ready to go.
With it setting on top I hit it 8 or 10 times and then clamped it down.
I clamped this on it and started with the 2 hammers.
I chucked the long one in a drill and sanded and polished the radius smooth but it was wobbling pretty bad. I used a regulator at a very low setting and started planishing it down but it marked it up with small dents, the radius is to big.
After fighting it for a while I decided this one was for learning and kept going.
Not pretty.
I sanded it with a 120 grit roll lock disk.
I looks worse than it is.
I will try again
