Hello,
I am still pretty new to Blacksmithing and building a new shop that will include a Blacksmithing area. I want to make sure I build a stout enough slab foundation to take even the largest of Blacksmithing Power Hammers. The slab will include a hydronic radiant floor heating. Does anyone know about foundations for these power hammers? How thick should the slab be and how large of area should it be so I don't ruin the rest of the slab or infloor heating system?
Thank you for any help.

Even the largest hammer hu? My Nazel 4B has a foundation 6 foot thick with over a ton of rebar in it, 6 foot long 1 1/2 bolts to secure it and took 12 yards of mud, and its not really a big hammer. The factory foundation plans called for 24 yards of concrete ( I figured with more modern materials I could get away with less) A big hammer (say a 1500 lb Chambersberg) weighs around 75,000 pounds, the anvil is 56,000 alone and would require a foundation that weighed about 300 tons....
Point being you really need to have an idea what you want to put in there. A 100 lb Little Giant would work on a 6" floor but would work better on a 3 foot sq foundation. If your thinking something bigger than a 100 lb mechanical hammer the foundation really needs to be built specifically for the machine
Whatever you are, be a good one.

6' thick....wow! I would be looking at about a machine weight of 3000-4000 lbs and about 100 lb ram. When you say specific, how large of area...ie, just the footprint of the machine or larger? If it is the foot print of the machine, does it tie into the rest of the slab floor? Could this ruin an in floor radiant heating system?
Really appreciate your. Help an input.

Methinks you are going to need a much bigger shop: http://toolmonger.com/2009/02/.....r-sort-of/
No matter where you go... there you are.

I would isolate the hammer slab from the rest of the floor. A simple matter of putting some 3/4 plywood or thick belting between the hammer foundation and the floor when its poured. For a 100lb hammer I would pour a 2-3' thick block that was 30" wide and 60" long . That would be a fantastic foundation that would be great for any one piece mechanical hammer. You have to remember that foundation is really an inertia block. the point of it is to keep the vibrations from traveling though the rest of the building and to provide mass for effective machine operation. More is always better but I think the point of diminishing returns for a 100'lb machine would be in that 2-3 foot thick range.
Whatever you are, be a good one.
