As I am getting up in years I find swinging a hammer for any extended period of time difficult. So with the help of my neighbor and the material out of my scrap pile we built 2 mechanical forging hammers.IMG_0016.JPGIMG_0031a.jpgIMG_0019a.jpg

With this set of pictures you can see that the support and hammer base are welded in place. The second picture shows the pulley system welded up.

I'll be watching this thread looking good so far.

Once the basic frame was completed it was time to add the hammer arm. This is a couple of leaf springs that were cold bent to be straight. Then the spring assembly was set on a pillow block for a pivot point.

The next phase was to attach the linkage arm to the hammer and spring assembly.

This last series of pictures is of the completed hammer

Have you thought about different sized wheels to change the length of the stroke of the hammer? Im thinkin like a short throw for sheet metal thickness and a bit faster rythem and a larger wheel to lengthen the stroke and slow it down for larger billets of material. I assume you will be forging the billets straight out of the furnace or after being heated with the torch, Right? It is a good lookin project and appears to be well engineered and nicely assembled. Perhaps a drawing and a Bill of Materials list for those of us who might be interested in copying your work. Looks like a really fun project and a very useful tool for those of us getting too old the swing a hammer for the time it takes to form a lot of shapes for our projects.

Pretty cool you need to get a video of it running and post it here. Thanks for sharing your project.

Next on the posting list is the hydraulic forging press
 
Fantastic build! I second the request for a video. Knowing me I would get something pinched in it.(hopefully only a finger!:roflmao:)
