November 22, 200817 yr wonder how much they want for it? I got a spot over in the corner of the shop..... Lol U got a forge big enough to handel it and some source of steam!
November 22, 200817 yr Brandon, Dave and Max, we are proud you chose to bless us with your participation on this site. God knows this country needs more young men with intelligence and gumption to go do what they can imagine. Stick with it!
November 22, 200817 yr So is this a drop hammer where the steam would lift the ram and drop it, or is a hammer that the steam powers the ram in both directions? A 100 ton seems like a lot of tonage but it really is not. edit: typo
November 22, 200817 yr WOW......... that thing is huge! I wonder how far away you can feel the vibrations?
November 23, 200817 yr Author That is metric tonnes so it is about 220 tons. The foundation is 8.5 meters deep that is alot of concrete ! brad
November 23, 200817 yr i already have one but would like to play around with that one a while. with the owners permission of course.what a neat picture
November 23, 200817 yr I have a Davy press broucher that shows where an approx 108 tonne hammer was replaced with a press capable of heavier work than the hammer. The press was of 5000ton capacity. This hammer stood 63 feet high, had built on top of it a pivot supporting 2 x 200ton post cranes. The anvil block for the hammer weighed 1000tons and was cast in place. Davy acutually replaced the hammer by building the press inside the hammer frame and leaving the hammer frame there thereby allowing the 2 post cranes to be utilised for the press. Big stuff!!!!! Cheers Phil
November 23, 200817 yr From the photo, I would say single acting steam cylinder, IE lifts only. I worked at a shop that had a 25,000# double acting hammer. You could feel the hit 32 city blocks away. It hit with a million foot pounds of energy. The first couple of blows were not a "bumpy" as the metal was greatly deforming and the hit was absorbed more slowly. The finish hits where the forging was almost finished were the hard, loud hits. For reference, the double acting hammers would hit much harder, as they are moving much faster at hit all things else the same. The 25,000# hammer had about a 5' diameter piston, and it was supplied with 145# 345F live steam. That ram was moving when it hit!!!
November 23, 200817 yr Wikipedia entry is in English and more readable.Creusot steam hammer - Wikipedia, the free encyclopedia And some pictures of big steam hammers working were posted in practical machinist.Photo: Vulcan Foundry Forge Work - Practical Machinist - Largest Manufacturing Technology Forum on the Web
