Default Various hand and pneumatic hammer patents

Small stuff, but they all get "powered" by an arm or air. I put copies of them in

http://www.eurospares.com/graphics/metalwork/

as an alternate download site.

cheers,
Michael

Hi Michael! Some neat stuff! you haven't found my phammer yet. Tim Barton asked me to keep it off the air till his book was out.(supposed to be in there) Keep looking your real close to finding it. I have the drawings so I can make a frame and lower die for it, another get a "round tuit" jobs. Take care! tt

Finding things with Google can be iffy if you can't figure out just the right search terms, returning either 1 or 2 wrong items or 500 of them. I don't know how up-to-date the online patents are. I hope you'll let us know ASAP about your device.

Is Tim's book still scheduled for this summer? I supplied him with some info/photos on hydroforming and the Pettingell over at The Crucible. I'm looking forward to the book.

I hope people find these patents interesting. Some of the drawings help to clarify for me how the machines work.

cheers,
Michael

I'm not sure about the release, he has been going round and round with publishers. I kept sending him more and more info til..... well he asked me to stop :o too much stuff. I do like looking at old stuff, I'm old too.....but still have much to learn! Thanks for taking the time to look up this info, I've got to sit down and go thru all of it. Take care! tt
