So I opened the door to power hammers last post, and I have amassed many files in my research over the years, so I will share a few more here.
First is a file I put together mostly from info. on the Iforgeiron site. There are 3 builds in this file and a couple small articles. First a similar version of "Rusty" then a well documented Helve hammer and the last an interesting Oliver anvil hammer.

This guy will never be called Rusty, few bearings used but the bushings are all oozing grease.
Very nice Helve hammer, used for working sheet materials.
Oliver The Hammer, very interesting, with a little practice, two hammers one smith is possible, lol.
I mentioned in the last post that I had lots of plan sets from the net. on file, I guess if I said it, I better back it up. "Krusty" is not connected to Jerry Allens 3 creations (Rusty, Dusty, and Super-Rusty). It is a larger nock-off, from what looks like Germany or Eastern Europe. It was originally for sale but it has been widely available on the net for many years. This is a 17 page plan set.

So in my research I looked at a large number of power hammer patents on the US patent site here are a couple of patents some may find interesting.
The first is a portable power hammer, click Patent: Potable Power Hammer to download. 290 KB - pdf
To download the second patent file click Power Hammer 3. 132 KB - pdf
I find patent files an interesting source of ideas. I am not looking to copy a patent but rather to see how different ideas are used to solve the problem at hand.
