About six months ago I rebuilt my hammer with better components. The old one was undersized and I never felt like it was working as well as it could have. I saved the head and anvil and started over.



I added a 5" x 14" cold roll bar to the anvil which increased the weight to 700# and brought the dies to my working height without having to raise the old anvil.



I upgraded to this 3" cylinder and you can see the three way hand valve which activates the clamping action. This feature is nice when you need a third hand. I have a 29cfm compressor and need it because this does suck the air. But it runs fast and hits hard (or soft) with great control.


Here is a shot of the 5 way valve used to control the hammer. I used a 5 way because the upgraded 5 way 1/2" main valve uses two pilots (no spring return) so a three way would not work.



I machined new dies from 4140 and heat treated them. They are welded to quick change plates for future dies.

Thats about it.

great rebuild, Matt. Like the quick change dies.
Hope your gonna do a video......of it mangling some metal.

Love it Matt. Is it for cold hammering or also for hot forging?

Mostly hot. But anything that needs a good smashing will do.

Hey Matt,
I'm considering rebuilding my power hammer. Could you share a schematic of how you plumed yours with the threeway valve for clamping?

Thanks
