You can't forge a square corner on round dies. Most things forged by blacksmiths have more or less square corner. The round dies are pretty much a one trick pony, pushing metal out in all directions....

So how is the Hammer running? Can't wait to see some video!

Go for it! If it does not work try a different way! :-)

You might want to change the dies. Did you use a coarse or fine thread?. I find fine threads tend to hold better.

How deep are the bolt holes? a little thread locker can do wonders. If you weld I would just tack weld in a few places.

I like mechanical hammers. I had a real nice 50Lb. Little Giant hammer that I really liked. If I had not of got out of blacksmithing I would have kept it & put a brake on it which makes a big...

I have been thinking of building a power hammer. Don't know if I will go air or mechanical. One thing I have learned is to work from the ground up. The base& mounting to the floor should be as heavy...

Do you have any of that heavy bar stock you made the anvil with? If you do I would fill that square tubing under the anvil with it. That square tubing will just crush down I believe . If you are...

I guess one thing to think about is how big of a die will fit with the ram guides you have. Another thing I have been thinking about is a comment you made about not needing to grease or lube the ram...

As I have said before, round dies on a power hammer aren't good for much. they will leave a rounded mark in with every stroke of the hammer. Rectangle dies with parallel faces is the way to go. DO...

I have been looking at your ram clevis set up & it scares me. I think the hole in the ram should be machined out of the ram material instead of welded to the top of the ram. Also is there is any...

Yes, the dies should be rectangular & the same size. Removable is best. Don't reinvent the wheel. There are many hammer & foundation design's out there.

Having a good foundation in the floor to mount the hammer to is important. You can't just have it bouncing around not bolted to something. I had a 50 Lb Little Giant bolted to 3 elevator counter...

I have found the best dies for forging are the same size , Slightly crowned"VERY Slightly" & have parallel edges. I prefer to use tooling to make fullers, hacks & other things. It appears you have...
