Power Hammers, Treadle Hammers, Olivers

Had a spring go on my goliath 60lb hammer today . very un traumatic .I noticed that the hammer was "slapping" a little and the dies were now touching . there was a slight change of sound . cut the leather off of one side and behold a broken spring . I have had 3 springs break on the 3 different mechanicals I have had ( two 60's and a 150lb ), they have all been origional springs (i think) . all of them were enclosed in a leather sheath to prevent the spring escaping in a case of breakage . This method works very very well I would recommend it .It may be that the LG springs are under a lot more force . Anyhow I have sent the broken spring off for re making and shou…

Can anyone help me specify what pneumatic cylinder goes with the bull hammer 125. I bought this machine in 2002 and it has been a good machine however the cylinder has been destroyed and scrapped before I could get any specifications off of it. If anyone has one that they would be kind enough to take pictures or pull a few measurements on I would be eternally grateful. Or if anyone can help me specify a new and different cylinder for it that would be great too. I’m aware of the problems with Bull and Phoenix and I am relatively sympathetic to their original builders . Thanks a million

Hey all, I've bought a 100-year-old two-piece self-contained airhammer. It's a Mammutwerke model MW3 from Nürnberg, Germany. It's in southern Finland though so it's not that far. The hammer body weighs 2200 kg/4890 lbs and the anvil 1300 kg/ 2890 lbs. The seller arranges extraction from the blacksmith shop and onto our Renault S150 midliner. I have a few questions I hope some wise man or woman could answer. Our midliner truck has a flat bed, made up of softer sheet steel on the frame, do I need to put wooden boards under the power hammer to distribute the load evenly on both the hammer and truck? Or is that even a stupid idea for some reason? I'm a little worried abo…

Hey all! I am getting my first big hammer this week. Woohoo! I’ll be picking up a 250# Murray hammer this week (similar in a lot of ways to a Little Giant of the same weight).The only problem is, it’s in Washington state and I live in Georgia. The drive isn’t the problem, it is safely moving the hammer I’m concerned about. I was planning on hauling the hammer in the bed of my F450 flatbed. It should handle the weight without much issue (approx 5500#) but I am still debating on having it standing up or laying down. With the machinery I have available, it would be much easier to have it stay standing. My question is, is this an absolutely horrible idea to h…

I am wanting to build a large hammer in the 150-200 pound range. I have already built a Clay Spencer 65 pound hammer and love it, but I want to build something that hits a lot harder but slower as well. I was told that a helve hammer would suit this better, told that it hits harder than the same weighted tire hammer but with less control. I spoke to Clay about beefing up the 65 design and he pointed me to look at the sizes of the 100#Little Giant to get an idea of how much to scale up. Which design would work best at 150-200 pounds and 150ish bpm?

This is my treadle hammer. Built using the Hans Peot modified, Clay Spencer Treadle Hammer plans, from ABANA. Two changes made to those plans, were heavier wall thickness all around, (1/4”,) and some inches added to the back of the base plate, (six inches total). I added base plate length, because I wanted to push the hammer against a wall, and retain room to access the locking screws, when adjusting the swing arm height. One aspect of this hammer that helps it hit hard, is twelve feet of 2-1/2” square, cold rolled steel, married into a 5”X 5”X 36” anvil. The anvil calculates to 255#. The tup is 75#. I call it Mr. Monkey. This hammer was a boon to my forge. Pr…

Hey guys, I am looking forward to buy a 16 kg airhammer, similar to the "Anyang 33". One big questionmark is the foundation of such a small hammer. I've read that the weight of the foundation should be around 50 x the hammerweight. So this would be 800 kg. Is this formula ok? I would pour the foundation with concrete with steel inside. I am working in the garden with neighbours all around the shop. I am a bit concerned about vibrations from the hammer. Is it adequat to isolate the concrete block with some rubber mats from the rest of the ground or should there be any other steps taken to avoid vibrations to be transferred into the ground? Tim

is there anything "wrong" with designing/building a two piece die; with the dovetail part bolted to the striking part of the die ?? Seems to me the hardest and thus more expensive part to machine is the dovetail section... Then the striking section could be a "chunk of metal" found at local steel pile/store/ebay/junk and then drilled, tapped and assembled to the dovetail. Or am i missing something.... ??

Hey everyone, Im looking for people who make dies for my 50lb little giant. I'm also wondering if it is cheaper to have them made than buy them. Any thoughts, suggestions? I know of the littlegianthammer.com site, but also just browsing around.

I have recently gotten hold of this 2cw Massey air hammer. It is originally from the NZ railway workshop in Christchurch, New Zealand and has had a busy and full life. Christchurch Blacksmith Noel Gregg bought it from the closing railway workshop in about 1985 and used it until about 2015. He was my landlord and mentor as a beginning blacksmith knifemaker 25 years ago. I was only allowed to use it once or twice during the 10 years I worked beside him. While it had not been used for 4 or 5 years, it had been stored well and no work was required on the cylinders.

I have started digging the hole for my Massey inslide hammer I am going for a two piece foundation so first I am making a concrete lined pit will a separate inerta block that will be on some form of isolation system that I havent decided on yet I have been toying with the idea of using shortened truck leaf springs as these arent a very efficent type of spring or have alot of natural dampening so will be less likely to start bouncing or some kind of captured rubber maybe urethane The last two photos are my highly detailed and accurate plans. The first is the hammer drawn out at full size to work out the required hights of everything leaving 1 inch of travel with…

Maybe a dumb question, i was wondering how much noise you get from operating a powerhammer like say a tire hammer? I live in a residential neighborhood and don't want to upset to many nieghbours with the noise from my shop. I was thinking of building a tire style hammer with some left over tubing a have laying around and some scraps from work.

How does one go about finding the origins of a nazel power hammer using the serial number thanks

Hello everyone. This is my first post so thought I'd give a little background. About 10 years ago I took a 6 week blacksmithing class put on by my local gild. I enjoyed it greatly and acquired a nice anvil (late 1700/early 1800s Mouse Hole) and built a brake drum forge. Life happens as it often does and I never ended up doing anything with them. Now the kids are older and quite interested as well. I am a habitual tinkerer and builder so have decided to build a power hammer. I have a decent sized shop to work in and a mill, lathe, and shaper plus mig and tig welders. Ok, long story short, I intend to build a Dupont linkage style hammer with a true disc style cl…

Hello, first of all, my Name is Alberto Esparza, I'm a mech engineering student working on a power hammer as a project for the course of "Mechanical Design" but I'm having some serious problems right now with the spring, so I don't know where to go more than you in the search for experience. What's the rate of the spring in the 50lb hammer? and those who have built their own power hammers with the Dupont linkage how did you selected the spring? any info would be awesome, thanks for your time in advance.

Been wanting one for a good long time, finally got the chance to get one. Found a 25 Mayer Brothers local to me in good condition in a working shop. Not much slop in any of the parts, bunch of shims in the caps for the babbits yet. Running on a 110v motor, which is a big plus for me as I'm almost out of 220v lines & I've still got to get the surface grinder wired in. Not to sure of the home made bottom die & holder thingy, but it'll have to suffice for now. Said it's been rebuilt when he got it. Got to run it a bit & look it over before taking the plunge. For once in my life, I didnt even haggle (I've argued the price of ice with an eskimo. In Fairbanks …

I'm about halfway through this build, and just getting started welding it all together. Clay specifies 5160 for the flat spring and W1 for the hammer axle, which I purchased, but he says nothing about heat treatment and they didn't come hardened. Does he just specify having higher quality steel for those particular parts or is it implied that they should be hardened and tempered? I was also planning on forging my eye on the end of the flat spring instead of welding on a pipe, which should be stronger in the long run. If anything, I'm thinking a quench and good blue temper would give both parts some extra strength and toughness to handle the impacts.

Im sure this has been answered so im sorry. I tried searching the forums and the internet for it but i couldnt find anything helpful. I just need to know what type of spring you would use for a treadle hammer? And maybe a rough ballpark of how strong it should be? (i know nothing about springs) Its for a very basic treadle. Probably like a 10lb sledge. Thank you for your time!!!

In about a week I will have the opportunity to purchase a Little Giant 25# trip hammer, New Style, number H-6161, manufactured in Mankato, Minnesota. While I have done some searching and reading online, and this forum, I still have a few questions. From what I can tell in the pictures, the hammer does not look rebuilt. Are these type of hammers electric, I have read that they are, but would like some clarification? Is this hammer one speed, or can I control how fast/hard the hammer hits? How large of stock does it fit, I have heard it will work on steel up to 2"? What do I need to look out for when I check the condition of the hammer during the auction? How much should I…

Hey everybody, I have been searching for new style kinyon air hammer plans for about a week now and cannot find them. Can anyone point me in the right direction?

I just spent the last two weeks watching Clifton Ralph and Dave Manzer’s RIP DVD’s on power hammer tooling and techniques. Both these videos are well worth the money and time. The Clifton video is a low quality production and not professionally shot but the quality and quantity of information is so valuable you can forget about it not being pretty. I’m sure I could watch Mr. Ralphs work for the next couple years and still pick up information, besides he’s very entertaining and a kick to watch. Kind of like watching a grizzly peel the top off your car, to get at your fried chicken and give you that convertible you always wanted.

I have a 6 ton electric log splitter and I’m wondering if upgrading the electric motor to a higher HP and possibly if need be phage and volt will increase its power to be suitable for a power hammer. I really don’t want to use an air over its so slow. Thanks everyone.

Have a chance to buy a Kerrihead 30lb power hammer, ever heard of this brand is it any good?
