Feukair Posted February 10, 2010 Share Posted February 10, 2010 Hey everyone, I spent most of my free time the past few months working on building a power hammer. It's not the most elegant one but it sure saves me alot of pounding. I modeled it after the japanese style of hammer where the anvil is a block and the ram is a simple round hammer. Maybe someday i'll make some dies for it and a different ram but for now this does it for me. http://www.youtube.com/watch?v=wDI4ond4c_4 Theres a few other videos of it there in my youtube profile...

Bob S Posted February 10, 2010 Share Posted February 10, 2010 Looks good. Works good. I like how you can squash the coke can and then stretch it out again . Bob Quote Link to comment Share on other sites More sharing options...

dkunkler Posted February 10, 2010 Share Posted February 10, 2010 It looks good, smooth speed control. I liked all of your videos. You might try bolting a few pounds counterweight opposite the crank pin to reduce the side to side wobble. Add a little at a time to find the sweet spot.

Spears Posted February 10, 2010 Share Posted February 10, 2010 That's a nice working machine. After seeing that I can't wait to get my power hammer finished. I like how the cat gets up and exits the room across the bench in the background. Thank you for the nice video. Quote Link to comment Share on other sites More sharing options...

Thanks, I have added some lead weights I molded up of various sizes since that video was filmed. No weights in the video. I have less side to side wobble now but was not able to eliminate it completely. I was surprised when I first fired it up how much speed control I could get my varying pressure on the pedal.

Nice hammer you got there. The coke can really show how well made it really is in that how smooth and straight the action on that hammer is. Great work keep it up!

The coke can really show how well made it really is in that how smooth and straight the action on that hammer is. Great work keep it up! Yeah I was worried how the alignment was and how consistently straight it would strike. A coke can was the first test then we had some fun with the video editing software.

Sam Salvati Posted February 23, 2010 Share Posted February 23, 2010 Feukair, look like you were going for a similar hammer to the japanese spring hammer? I did some close looking and studying of them and how they work, the faces are very crowned but round like a hand hammer and the lower die is bigger, allows you to do a half on half of blow to one side of the die which allows forging the bevels and/or spreading the spine and extremely fast yet highly controlled metal moving. you've probably seen this video, but watch the metal closely under Murray's hammer and where he puts it in relation to move the metal: http://www.youtube.com/watch?v=0oShQNbkdZc Quote Link to comment Share on other sites More sharing options...

But mostly be cause it was the simplest design that i had seen. I had considered making the combo drawing flattening dies that most hammers have but i just couldnt come up with the materials or a design that would fit with the rest of what i had to rig. In the end i had an old 3"round 10 pound sledge hammer head and some square tube with a 3" ID so i decided to weld the hammer head up inside the tube and fill it will lead to make the ram. Then i chose to make a larger square anvil because it occured to me that this would be a model similar to the japanese ones. I don't know if i'll ever forge bevels with my hammer, i've tried on a couple of scrap pieces and it does seem possible to rough in some of a bevel, but until i'm better with it i like the hand hammer control for that. Thanks for that video, i actually had not seen that before. Man he really runs that hammer fast sometimes, seems as fast as a sewing machine a couple times LOL...thanks again.

Nice Piece !! did you have a set of plans when you started the project? Where did you get the drive wheel off the motor?

Feukair Posted March 30, 2010 Author Share Posted March 30, 2010 Nice Piece !! did you have a set of plans when you started the project? Where did you get the drive wheel off the motor? Dick Poeske [email protected] Thanks, no specific plans, modeled it after the clay spencer design, scoured the web looking for pictures and kept my eye out for pieces i could use. The steel drive wheel i got from a tractor supply store it is a hub that u would weld a sprocket on to. The sell lots of different sizes and shaft diameters, only about $6 for that piece.

Feukair Posted April 3, 2010 Author Share Posted April 3, 2010 Feukair, what was the anvil made from? The anvil is a piece of the ibeam same as the hammer frame. I welded a piece of 1/2" plate on the end. Put two lag bolts thru for mounting the small block and welded those underneath. Then i welded some 3/16" plate on both sides of the ibeam. Put it upside down and filled it with cement, let it dry and welded 3/16" plate on the bottom. I weighed it, came poy to over 250 lbs. It works great for an anvil.

empireweld Posted April 3, 2010 Share Posted April 3, 2010 Nice job! What is causing the little shake in the video? Is the hammer vibrating the camera? It looks like a wince or flinch of the eye at each blow. It also looks like a thermal shock wave. Quote Link to comment Share on other sites More sharing options...

For this vid the camera was on a tripod a few feet from the hammer. When you hand hold the camera it doesnt do that. Quote Link to comment Share on other sites More sharing options...
