Frosty Posted November 21, 2008 Share Posted November 21, 2008 I don't think so, there's a skookum looking plywood and lumber form supporting the foam. It looks to me like the foam is supposed to be the interface between the hammer foundation and slab. I'd just want some very positive reassurance in writing before using foam like that.

Paul B Posted November 21, 2008 Share Posted November 21, 2008 I have designed quite a few foundations for equipment, mostly power presses, up to 2000 ton machines. The foot print is usually 2 x the foot print of the machine providing the earth beneath it tested OK. Most times we drove piling to bedrock. I don't think this would be necessary for a hammer. It looks like there is foam under the base, this could be a problem. The foam around the edge is to isolate the base from the floor of the shop.

Sask Mark Posted November 21, 2008 Share Posted November 21, 2008 For a power hammer, as Paul mentioned, I would agree that the hammer foundation sitting on compacted granular should suffice (1+ foot thick) assuming the subgrade is packed and consolidated enough (ideally undisturbed). An asphalt impregnated fiberboard (3/8 - 1/2" thick) as an isolation joint between the foundation and the slab is usually advisable. This is the type of foundation we built at a local steel mill in their spiral pipe operations. Quote Link to comment Share on other sites More sharing options...
rustyshackleford Posted November 21, 2008 Share Posted November 21, 2008 Looking good Minotaur! I'm glad to see your progress, it looks like it will be done before you know it. Quote Link to comment Share on other sites More sharing options...
Jura T Posted November 21, 2008 Author Share Posted November 21, 2008 It looks like there is foam under the base, this could be a problem. The foam around the edge is to isolate the base from the floor of the shop. Yes, there is foam under and around the base. The concrete was poured last Tuesday, the picture shows the mould before that. By the specs the foam can easily take the static load of the base and the power hammer (it should compress less than 2%). What happens when I start hammering is another question. It could be that it compresses in long run. I couldn't afford polyurethane rubber, that is used in industry for shock absorption. Quote Link to comment Share on other sites More sharing options...
Paul B Posted November 22, 2008 Share Posted November 22, 2008 Just curious, about how much does a power hammer weigh. Quote Link to comment Share on other sites More sharing options...
Jura T Posted November 22, 2008 Author Share Posted November 22, 2008 Just curious, about how much does a power hammer weigh. Mine weighs 2300 kg (~5000 lb). Quote Link to comment Share on other sites More sharing options...
divermike Posted November 22, 2008 Share Posted November 22, 2008 My tire hammer weighs in about 700lbs, light enough to move with my tractor and wrestle in position by hand. Quote Link to comment Share on other sites More sharing options...

Frosty Posted November 22, 2008 Share Posted November 22, 2008 It's a mechanical power hammer that uses a tire on the crank and small drive wheel on the motor to drive it rather than belts and clutch mechanism. Frosty Quote Link to comment Share on other sites More sharing options...
Jura T Posted November 23, 2008 Author Share Posted November 23, 2008 That must be for some serious work. Its an old Russian hammer with cast steel body. The ram weight is 110 lbs. Modern air hammers with similar ram weight weigh maybe about a half of that of the Russian beast. Quote Link to comment Share on other sites More sharing options...
Jura T Posted November 24, 2008 Author Share Posted November 24, 2008 It snowed quite a bit last night. After some shoveling I was back in the flamy business that I started yesterday. Quote Link to comment Share on other sites More sharing options...
Jura T Posted December 18, 2008 Author Share Posted December 18, 2008 Some more pictures. The excavation around the foundation was filled about two weeks ago. Then there was a close disaster; I had hired a guy to build the frame with me and a couple a days before we were about to begin he broke his achilles tendon. Luckily I was able to find another guy on very short notice. He will finish the building for me (except for roofing). It'll cost me somewhat more, but then again I will be able to spend more time with my family. Quote Link to comment Share on other sites More sharing options...
nthe10ring Posted December 18, 2008 Share Posted December 18, 2008 (edited) That is really looking good now. Im just looking at the size of the timbers your using, looks like nice stuff. They just look heavier than the regular 2 by stuff we have here, are they laminated or regular stock.

The roof beams are laminated. I'm really happy of how the building is progressing at the moment. The guy doing it is really fast. Quote Link to comment Share on other sites More sharing options...
Lysdexik Posted December 18, 2008 Share Posted December 18, 2008 just a sugestion. Metso minerals, used to offer a pourable dampening material containing sorbothane for use in their rock crusher bases. Crushers weigh more than your hammer and have 5Tonne moving parts. The stuff was not too expensive, and I think they are a Finnish corp. Paul. Quote Link to comment Share on other sites More sharing options...
Frosty Posted December 19, 2008 Share Posted December 19, 2008 Looking good. It's better to build stout and not need it than have something give. Frosty Quote Link to comment Share on other sites More sharing options...

Paul, thanks for the info. I couldn't anything on that on Metso minerals www-pages. Is that meant to be used directly under the machine and what kind of layer thicknesses are used?

RobDobbs Posted December 21, 2008 Share Posted December 21, 2008 Hei, Minotaur. The shop is looking great. I'm quite jealous as I had to leave mine back in Texas. I am living in Lepp Quote Link to comment Share on other sites More sharing options...
Jura T Posted December 21, 2008 Author Share Posted December 21, 2008 Rob, thanks for the offer. I'm now paying to get it finished, and thus don't need help right now. You are welcome to visit the shop once it is ready. Quote Link to comment Share on other sites More sharing options...
Jura T Posted February 19, 2009 Author Share Posted February 19, 2009 I guess it is time for an update. The building itself has been been more or less ready for about a month now. I've been quite busy so all I have done during that time is painting the inside and sanding/treating the floor. Yesterday I drove to our family cottage to get the blacksmithing stuff from a small shed I've been using as a shop during last couple of summers. The new shop still needs all the wiring to be done. It has somewhat difficult to find an electrician. Quote Link to comment Share on other sites More sharing options...

Frosty Posted February 19, 2009 Share Posted February 19, 2009 That is looking pretty! Your tools look pretty lonely all spread out like that and in such a clean space too. If I didn't know this was a brand new shop I'd have to wonder about your sanity. I also see the car is in a car port (what we call a relatively open, roofed over place to park the car instead of a proper garage) and your tools are in an enclosed, lockable space. I like your priorities. Frosty Quote Link to comment Share on other sites More sharing options...
