I've been working iron for some fifty years, by hand, and with power hammers, and the key is finding the "harmonic frequency" regarding the mass of the hammer, and that of the drive mechanism, in reciprocating mass, and aiming your rpm to make it. There is a natural harmonic, which leaves the hammer "floating", generally higher than the harmonic you want, however you can simply change ratios until the "hammer" is maximizing the distance traveled in power stroke to rebound, which gives you the best power transfer. The mass of the hammer and linkage, and the mass of the driving shaft, pulleys, everything feeding the crank, control the natural frequency, so set hammer weight to maximize stroke, and modify the drive to get the most, and only after getting there, work on the spring, greater or lesser force, to match the harmonics you've established first. It's been fifty years since I was on a power hammer, but they all have the same physics factors. I too, do most of my engineering with old farm equipment, auto parts, it is the single most cost efficient means of "recycling", simply re-using and keeping the value factors existing, far better than cutting and welding up, or melting and casting, to forge again. I've heard of "hardy hole hammers", but never seen one, I am motivated to build one, to sit on my Fischer 1917 150 pound anvil, I'm getting creaky in the bones and joints, and I've just finished my first "propane forge", always used coal or coke before, but am looking forward to a new experience. Thanks for showing this bit of interesting engineering, I hope you get great pleasure out of your forge work, I've always taken pleasure in the heat and color of the iron, how it moves, when yellow, and that one can completely control it with blows of the hammer, in precision. Thanks again for the motivation!!

I know a guy, comes by all kinds of junk, has all kinds of ideas, like you, if he could live another 1,000 years he might get it all or most of it done. Great video, thanks.

Nice hammer Mike! Gods speed on the healing from the fire! This kind of build is further down the line for me. I am currently building a Davinci Cam Hammer with an 8 lb sledge. Just completed my Gas forge with Fire brick and an old weed burner and did some heat treating today. Made the chamber small so it works great. Thx Christ Centered Ironworks for the forge tips today! My first forge is a lump coal BBQ conversion. A lot less calls from the fire dept now since they always think the place is burning down with all the smoke! I like your style! re-purposing! "The Phoenix rises from the flames even more beautiful than before" !...Thx for inspiration!

Great job, love the compact design.

"repurposing junk" It's art!! Well done.

i love the simplicity of this design i got to rethink my way of building one thx!!!!

Nice setup man. When building a powerhammer, I really gonna consider this design.

Awesome build! Great design.

Cool man, if it works it works, just dont get fingers too close, that will hurt! Building one now, got a part from and old milking machine that originally powered a stroking suction pump thats exactly the action needed to drive a ram hammer once I sort out and make sure I have all the junk needed to go ahead! I need a hammer and anvil but have ideas and crazy expectations so fingers crossed, safely in my pockets, will see! MAYHAP

Thanks for the neat video. That is one of the nicest little hammers I have ever seen.

Awesome design Mike very cool

Very cool build, Mike! Really like that design...looking forward to seeing it draw out some steel

Thank you for this video. My workplace is really small so i search for a light small hammer and your video help me a lot. Greets and thanks from austria!

Great job on the build! Somethings to consider for your design... #1 make your yoke box a bit taller #2 invest into a thicker spring with better tension..The hammer will have more stroke this way and about twice the hitting capacity :-) hope this helps and again great job on the hammer.

😆 I'm using a dead Ford pickup idler pulley and an air compressor flywheel on my own design. Hadn't considered installing a break before now. That might be a good idea for my design. Thanks for sharing.

Excellent on all fronts! Heal first, the rest will follow. Again, it a great example of repurposing.

Love it! Great use of materials. Get well soon brother!

fantastic job

I've been meaning to weld up a power hammer for myself with my everlast welder and some of the spare metal I've got around the shop. Yours seems to have a realy smooth stroke there.

I appreciate all the interest in this lil power hammer people.Please be patient on my moving metal video of the hammer.I had a fire at my property(field fire) and I got burned pretty bad on my legs im in alot of pain and healing up.I have been doing a lil smithing just because Im dedicated to making my daughters some goodies for the a house warming and birthdays,just doing some whitesmith work right now.Thankyou for your understanding...its coming as soon as im up to it!

I hope you heal up good and fast, burns can be a tricky thing and unfortunately the pain will likely stay to some degree. I've had some experience with burns myself, about ten years ago I was visiting my old shop teacher and one of the students left his project on the anvil. The little moron hadn't dunked it so when I picked it up to move it I got a heck of a surprise. Few children will ever get a more thorough lesson on profanity...

After you are healed over ocean water helps stop scaring. You don’t want scars aesthetics and they are sensitive to heat. So trip to the beach in order about now. I was going to say great job on the hammer super creative.

Just found your channel and Subscribed. Very nice

To Mr Rock Mike: Good boy ! Try to stay active. i hear your joints ache; . i am semi-retired ( owned semis, too ! ). Do you add spices, to your breakfast ?. Turmeric, ginger and cinnamon, along with other rather HOT spices, mixed with healthy foods, at / on your meals, WILL HELP WITH THIS ALOT ! Also, try to eat at least 2 soft boiled eggs, with turmeric and brussels sprouts. I've been doing this for about 10 years, and my right knee, is healing up. From driving trucks/buses/taxis most of my life. EAT healthy stuff, from '' spade to spoon '. Those boxes, and frozen foods, coming from a factory, WILL HURT / DAMAGE THE BODY. Stay away from crap / fast food (poison). Anyway, good work you do here. Nice design, very strongly built hammer. I like to use rail road track, and other steel used on rail lines, in the garage. Rail is 1084 steel, very hard. TAKE CARE OF yourself, and God Bless !

I like it! I learned a few things. I gotta build a thing for drawing out stock for tong reins soon. Trying to ramp up production a bit.

I love these homebuilt hammers and soon hope to join the club

Love the googly eyes. I hope you are healing up well.

Subscribed - nice work, I am always impressed by the things people build by reusing stuff.

Well done.

That is a really clever little hammer. I really like the brake idea, never seen that before. Hope youre healing up okay, might need to wear long pants around the forge for a while, the healed skin might be a bit heat sensitive for a while.

Pretty Awesome Mike , I’m guessing with all the old Farm Equipment you are a Farmer ? My Dad was a SeaBee in the late 50s in the Phillipines and they were redoing all the old WW2 Airstrips over there he always told me that if you were looking for good workers never underestimate old Farmers because not only are they excellent self taught Engineers , they are usually very strong although they may not look like body builders or realize how physically strong they are they usually are stronger than the average guy in the Navy they had guys from all over the United State’s BTW my Dad grew up in a rural area and one of his neighbors had built many homemade tractors and farming tools using old trucks and Automobiles he often powered implements by hooking up belts onto the drive tires and lifting that tire off the ground I saw a sawmill he made that way

Graet build! From expierience I will say replace the pillow block with a forged or solid steel babbit bearing. The cast iron pillow block will break. Other than that super cool!

Very nice

That's badass I like to pick up crap off the side of the road then collected and then go to the pile and make awesome stuff out of junk presently I haven't found a whole lot of farm equipment junk despite there being tons of farms around meI guess I should go door-to-door and ask a couple old Farmers if they have any broken pieces of equipment still laying around and then I'd like to take it off their hands for free if it's broken and not usable to them

Really great but I would imagine you are going to wear the drive belts out quickly? There doesn’t appear to be any clutch?

genius.

First of all I hope you're healed up from the fire. Around two years ago I started a benchtop hammer, your video got me to dig it out and have a look at it. My question is, is the spring you are using very stiff or does it have quite a bit of flex to it ? The hammer looks great, thanks for sharing. 👍 🔥🔨

maybe a tube bender type shape of spring sleeve, on top of the hammer part that slides across the spring to smoothen its sliding action would take some of the violence out an give less wear against the spring an sleave so it dont catch on the spring coils

Man, that's awesome. I really need to acquire some junk. But you need a cage around that little beast. I would feel really uneasy running that thing right in front of my face. I've seen too much shit explode into pieces to be trusting any of that to hold together forever.

Have you looked at the Japanese power hammers, they use like rope or straps to suspend the ram from the crank

Great build!

Aught to name this banger the noisy cricket. Nice work man but I have 2 questions. You’re break system seems like it could stress your motor and burn it up, have you had any problems with that and if you have what do you do to combat it? Also that spring seems like it might rob you of some downward thrust power, if it does, is it still enough to work metal without having to excessively heat? I like the design and might build one myself that’s why I’m asking

This is exactly the size hammer I have wanted to make, the parts have been sitting in my shop for almost a year but after watching your video, I dusted everything off and started building. 👍 The only question I have, for now that is, what size motor are you running? Thanks for posting and I hope you dont mind if I use certain aspects of your design. Mike.

Hey Mike, I love your build, simple but by the look of things pretty affective. I'm in the process of building basically he same thing. I used a garage door torsion spring and made the yolk some what taller also a longer, heavier ram which I may need to lighten up. My main concern is the size of the motor to use HP wise. I have 220 in my garage so that's not a problem. Any help with size motor needed would be greatly appreciated.

Would like to see pics or video of your build.BIgger the better on the motor right,you can always tune it down with a variable voltage gizmo.

Cut that spring in half and get some 1/2” plate and make a couple of washers to go on each side between the spring and the hammer and that should make it stay in the middle.

Una pequeña maravilla

nice try but i don't think the short cut with spring mechanism will last .. i think sooner or later you will have to change the design to proven working little giant concept .. will be way more smooth and efficient run .

Smaller power hammers can go faster than larger ones. I believe Little Giant 25lb hammers are made to run at about 225 blows per minute (RPMs). My 25lb Kerrihard power hammer has "250RPM Max" stamped into the flywheel casting. I think I recall seeing some lighter planishing hammers running at 300-400 blows per minute. Most heavy hammers 50lbs and up are around 100-150 blows per minute. (My Kerrihard can get kind of scary at max speed)

How does the foot pedal operate? Does it just add and release tension to the belt?
