So there's a good chance I have 5 feet of 7 inch round coming my way, that's 650 pounds (with a 10:1 hammer anvil ratio that's a 65 pound head). I already have a great post anvil which leaves the only logical project for this big round is a powerhammer anvil. I have studied powerhammers DEEPLY, of just about every type and size I can find info on. So in this case it's sort of an overload, I've drawn up designs for tire hammer, helve hammer both guided and non, air hammer(incorporating the 5 inch OD 1 1/2" ram 2 foot travel air cylinder I have), strap drop hammer, rolling mill with 12 inch wide rollers. So I want to know if this was yours what design would you go with. I want to hear/see your ideas and suggestions!

PS, already have my awesome little Anyang in my own shop and access to the big Say Mak at work, this one will be built for the sake of building it because all the parts have come together finally.
 
Tire hammer seems like it's one of the most compact design ideas, I also like the overhead spring hammer, and they both seem to be equal in complexity as far as building goes also seem to be equally effective if well built though I don't know much about hammers. I've nothing in particular against air hammers except that you need to run a separate machine to make it work.

How would you incorporate the 5' of round into a hammer design? Too bad it wasn't 10" x 2.5' that would be perfect for a hammer anvil 666 pounds :)
 
Cut about enough off for a comfortable anvil with dies height and use the rest possibly for the ram.
 
That stuff is no good for a power hammer Sam.... I'll get rid of it for you though, so its not getting in your way ;)

If it was mine... not quite sure what design I'd go with. In terms of simplicity, the spring helves are not too bad and will definately do an alright job, though for some reason I've always thought that when it came time to build myself a power hammer I'd go with the tire hammer design.... unless I went really fancy with an air hammer.... but in that case I'd probably want to go self contained.... dunno, tough call.... I think the only option is to get more materials, and do them all, thats the only way to be certain ;)
 
Throwing ideas/options out there... You'll definitely need a heavy duty base of some sort to keep that 7" round from making holes in your floor... to lessen the problem you could cut 3 equal length of 16" and weld them together into a clover and weld the remaining 12" on top.

That will give you a 28" high anvil which you can put a 4" base underneath and 4" die height and have a comfortable 36" working height.

Or just use a peice of 1 inch plate that is 2 foot square and cut out all that useless cutting and welding.
 
True, so you'd have to lose the 10:1 anvil to hammer ratio if you want a 65# head or go with something like a 40# head and keep the 10:1 ratio. Guess it depends on what you consider to be a comfortable working height.
