I'm thinking it's not been asked.

Do any of our membership own and use a powered hammer?

I've got one, the latest, using motor to drive a shaft to lift and pull a set of leaf springs. Krusty mod I'd guess it's called.

I can change out the leaf's and hammer weight in about 30 minutes and go from 75 lbs to 120 lbs of beat the hell out of what ever is between the anvils.

I typically keep it with the 75 lbs setup as this is just fine for what I usually need, plus it's just right for heating and making an edge on shredder blades in lieu of grinding like most folk have been accustomed to doing. Although, when you grind off material, you lose seasons of use in doing so.

Just asking.

What is in your shop?

I don't have one, but about every three to four years when I have a little blacksmith job at work, I dream about building one. I will research it, and start coming up with plans, but by then I am into more important work with no sign of any more blacksmith type work in near future so those plans get forgotten about.

The boss has expressed interest in buying a good gas forge and power hammer to be better equipped but I am afraid that probably will never happen, unless he wins the lotto someday.

Building a homemade power hammer is in my list of "to dos" someday, if I ever get around to it!

I bought the motor, pulleys, belts, bolts and springs etc. the rest was scrap.

but about every three to four years when I have a little blacksmith job at workAfter doing a set of shredder blades by hand after 76, I decided I could use one.

While doing my 4th set I was dreaming about one.

It took 10 more years before I made a mechanical arm with a good sized head and wore out the left leg.

I tried to make a pneumatic drop hammer with help from a few members here if memory serves, but sold it unfinished while at a hammer in. Probably should have finished it.

I'm fixing to go back to a tire driven vertical drop with the arms and spring in between. Seems to be the least intrusive as far as floor space and that's where I'm headed back to.

The one pictured is by Steve Barringer(sp) from some years back.

Mine should be about the same cept color I'm sure.

Haha, that's great! ..I watched /listened to it a couple of times just to listen to that engine...

Not knowing anything about that type of hammer I am under the impression that the operator was controlling the BeatPerMinute by the tension he was putting on the belt via the foot bar.. wouldn't that wear out the belt quicker?

I suppose at that point in the game belt wear is just a minor inconvenience :cool:

Thanks for that, the sound of that V8 was awesome --

.

"Walking to my truck to go to or leave work leaves me dreading the sitting down and oh my gosh, pushing the pedal in with the left leg. I'm regretting the little S-10 did not come with an AT. sigh"


As someone who has traveled down this path, I can sympathize. ..
One of my trucks needed a whole lot of push, I don't know how much in poundage but it was like doing deep knee bends on one leg.

I'm sure that was a factor in my trip down the knee replacement lane..

I have owned a little giant style hammer, 50 pound, and currently own a pneumatic. As far as a new build goes, I think a pneumatic is far easier. Mine works well. The only tripping point is the connection of the air cylinder to the tup. Mine wears out from time to time. Most air hammers I have used had similar issues.

I have 3 and use them all. Each one has a job to do. The 1928 100# Beaudry is the work horse for drawing out and tapering. The 110# Big Blu is used mostly for spring fullering and texturing and the KA75 is for punching, chiseling and "Hand" work.
Years ago I built a small one 22# or so. It was ok but too small for most work. The Blu and KA were bought new, The beaudry was bought and brought in out of the rain (yep, sitting outside with what was left of a tarp laying in the weeds next to it). I stripped it down to the frame and rebuilt it. It's a pleasure to run now.

Haven't done much pounding since the arm surgery. It is on my wish list and I know an old guy that has three of them. Missed one about ten years ago that a widow sold for $100.00.:eek: I also like someone else stated, have a couple different piles of plans for a power hammer laying around the shop. Don't think I am going to live long enough to finish that project.

WOW! I've never seen a powerhammer that big much less powered by gas!

much less powered by gasuh umm.. as in petrol? of course those that drive piles use all type of fuels. a friend has one on a barge that uses diesel and hits harder than thors hammer.

I have been scratching my head but without pictures I can't visualize how you would swap out from a 75lbs to 120lbs with changing head weight, leverage ratios and a few other tidbits.. So to be able to switch it out in 30min is awesome...

Hows about some pictures of the mystery machine???? Love to see it..


I had all the items for an air hammer.. would have been variable weight with variable height control with one strike capable..

Sadly when I stopped smithing and my Dad was hell bent on getting rid of my stuff.. So everything but the shuttle valve and micro switch went to scrap..

The weight is changed by overall width and depth, not height. The stroke stays the same and I found a nice alternate in just adding different leafs as a complete set for the heavier weight.

The strokes remain the same, but I do change the belt to a slower set pulleys on a double pulley set to allow a tad slower hammer hit with the heavier weight.

The anvils stay the same, both upper and lowers to allow less die setups.

It works for me just fine. Works even better since it is now planted in concrete that is both deeper and sized for the hammer set into the original slab. That was the hardest part of the build due to not having an easy way to cut a slab.

I run a 3hp ele motor. Overkill, but the hammer loves that motors size. I bought the motor thinking I was going to make a dual buffing station from hell, but that never happened.

Thinking, I do have the set of plans I found on the net which is all I used to make this one and the smaller one I gave to a friend wanting to do a little work in his garage. As he's handicapped, he can do all of his smithing from his wheel chair. I like to spend time with him just to watch how he moves to and from each station he's got set up. I'd like to think I've helped him, but in reality, he has the ideas and I handle the grunt work. lol

The first and most impressionable pictures I found on these hammers was on 'appaltree.net'. I think.

Just hand drawings or musings of the creator as he was coming up with what his build would involve/evolve into. (http://www.wcbg.ca/wcbgsite_015.htm)
