Had an account here a few years ago...can't get back into that one, so got me a new account now.
Just about finished gathering the heavy parts for a junkyard guided-helve hammer, figured I'd post the project here to make things more interesting.
It's a true junkyard dog, and as such won't be as efficient as I'd like, but I'm trying to make it as good as I can while keeping the $ down, and finding decent heavy scrap for short money is becoming pretty impossible in my area as the scrap scroungers become Rockefellers. I'll be using it only for moderate work, not quite hobby but not quite the Westinghouse foundry. Maximum stock I'll be working is probably 2" x 2", very rarely.
Main mast and head/anvil braces are cut from 12" x 6.5" H-beam
Base plate is 2' x 4' 3/4" plate...much lighter than the 1" road plate I was hunting for, but after a few weeks of searching around, and calling friends of friends, this was the best I could locate, so I'm running with it.
Got UHMW-PE for the guide lining, and I'll be mounting it in 3" bands inside the guide, as I saw on someone else's hammer design, rather than as solid sheets. I'm not sure what grease will be best to use on this, or if I should use something beside grease entirely.
1" pushrod with turnbuckle
Leaf spring is from the rear end of a Pierce fire engine...20-ton vehicle with single rear axle. Needless to say, it is extreme overkill for this hammer, but it was free. The spring is so heavy, it's possible I may need to use only a single leaf of it, to ensure it will actually flex! The photo doesn't properly communicate how heavy the thing is. The left over leafs will be great spring steel for the stock pile.
The anvil base/die holder is a sticking point. It is 7"x7" square tube, and it was a telescoping outrigger jack from a fire department ladder truck, actually rated for 10,000lbs. It is geometrically perfect to serve as an die base, but of course it is heavy, but hollow, and will not be a 10:1 hammer anvil ratio. While I'm absolutely sure it will absorb more energy than solid steel, and it will reduce efficiency, I'm not entirely sure the difference will be drastic enough that I shouldn't use it. It seems logical that this square tube shape will deliver most of the force evenly down to the steel plate and concrete floor, and be pretty d*** solid. Filling with sand of course just deadens the sound, and does nothing to actually increase density.
Like I said, I'll be using it for moderate work, and I just wonder how much of a drawback it would be to use this as a base. Dies will be made from railroad track cap.
Well, there's the short intro to the project. Wish me luck, and I appreciate any input and pity.
Oh P.S....Home Depot Tool Rental for the saw. Saw was absolutely awesome for H-beam cutting...cut very square, very little cleanup grinding needed.
