Building your own Power hammer vs Factory Hammers

[DSL PWR]

Why not build your own c frame and mount an air hammer to the top? Just get the type that has a quick coupler instead of the spring and you should be off to the races. You could also adjust the speed via a regulator, or a needle valve. It doesn't have the flair of most of the other ideas, but it should work.

That would be a planishing hammer, which does a decent job of shaping, but is really meant for smoothing panels.
I shape with my planishing hammer, but you really need something with more power if you want to shape sheetmetal faster.

Here are some small examples of shaping with the planishing hammer.

You can't increase the speed of a free falling mass by increasing the mass. One of Newtons laws. That feather and apple thing. Or was that William Tell?

The potential energy is increased linearly with the height the mass is lifted, but the speed of light doesn't figure in...at least in my shop.

Point taken. But if the mass has not reached its terminal velocity, increasing the stroke should result in more speed and so have more energy.
