Watch to the end for further exciting announcements
We're considdering developing both DIY patterns/designs and manufacturing finished power hammers for you to purchase, please leave a comment to express interest if you would like to buy one so we know if it is worth our investment.
Useful information:
-The compressor I use is 15cfm, 150ltr, 3hp and single phase.
-The head weight is now 70lb and is solid steel.
-The impact force is roughly 1500lb on a 25mm(1") area.
-Can forge 50mm(2") steel comfortably with excellent control.
-Parts cost roughly £350-£650 to build (not including the compressor) depending on your steel supplier.
- Foot print is 500mm(20") x 400mm(16") and is a maximum height of 1800mm(71").
-using quick exhausts valves does NOT allow the saftey feature of the new electronic valve. but can still be used if wanted.

[@bjwatts659]

I just found you today on the KZbin’s and I have to say going through your vids watching you build the hammer initially and then re-engineer it as you go while I sit here on my anvil in my shop has been awesome!! I have aspirations of building one of my own and I think I’m gonna have to purchase your drawings your design is one of the simplest and best I’ve seen. You have to give the hammer a name though! Myself being a massive Jeremy Clarkson fan I’m inspired by his penchant for naming things. It could be THE POWER THRUSTER. Or perhaps THE PNEUMATIC HAMMERY THING OF DEATH! Haha or just Geoff. All kidding aside you do some awesome work your videos are great and thank you for the time you spend and sacrifice to make them. Cheers Mate! From Indiana in the United States 🇺🇸

[@jamesspry3294]

When i used to design assembly machines, it was always "hardened end stops". Nothing else was even durable enough. Once you've designed something where the cylinder ends get destroyed... you decide to take the advice of the old blokes who've been there and done that... I'd weld some brackets onto the bottom of the round moving part, and fit those hardened end stops to the fixed RHS parts. That way you have minimal changes to your fiddly cylinder. Just my 2 cents worth...

[@joshuadelisle]

@@jamesspry3294 thank you. It's got electric proxy sensors now so it never touches the end stops and cycles via electronic control. Cheers J

[@IronB2]

I really think you should tackle the problem of the ram extending back up and having to catch it with your foot controls. Theres a number of different simple solutions to that problem. Compression spring bumper, extension spring catch to reduce the velocity, etc etc. I dont have a power hammer myself yet, but I do like the simplicity of yours. I have all the parts for that laying around my shop right now and I'm considering building something similar myself. I do know however, your ram is going to jam up eventually if you allow it to continue extending fully like that. Anyhow, Thanks for the idea and the vid!

[@joshuadelisle]

Thank you, I'll give it more consideration, the rubber cushion seems to be doing well so far. If it breaks I'll do something then, I've got 2000 nails for it to make with some new tooling so that will be a good endurance test. Cheers J

[@timbishop97]

Josh, I am so glad to see new posts from you again! I had wondered what had become of you. It seems like you have pulled through a tight spot and returned better than ever. I get it. I still insist that my forge work pays for all forge improvements (or maybe that's my wife), and I am looking forward to a busy Christmas which will allow me to add some things I have been wanting - not the least of which is a power hammer. I have been groping around in my head trying to decide on a cost effective design that wouldn't have too many compromises, and here you come and hand it to me! Thank you. Brilliant idea and execution. It may, may have a few compromises or trade one optimal condition for another as people have said, but the proof is in the forging. May I suggest that instead of a bump stop to prevent piston slap, someone modifying their own build of your hammer might try a spring to slow the cylinder as it nears the top of the stroke? It would add power and speed on the down stroke too. I am first building a crane to go on the bed of my 2001 Toyota pickup to load and unload heavy objects like a portable welder/generator, 20 gallon propane tanks, steel, or a stolen safe. Then I hope to be able to build my own hammer, using your plan. Thanks again. It is a life worth living!

[@joshuadelisle]

Thank you Tim for the encouragement on this journey. Another person had a good idea to have stop on the valve so it does a slower return and make it like a switch so I get rid of needed. Might add a small motor and cam mechanism to the valve and control it with my Tig pedal like a normal power hammer. All the very best on your adventures and catch up again soon. Cheers J

Great project! This is an excellent design. You made an improvement by moving the valve very close to the cylinder. I believe if you would weld up a small volume of steel tube maybe 3" x 3" x 3" and place it right at the input of the valve, it would act like an air capacitor and give even better efficiency. Like a micro air tank right before the valve.

[@crazycoyote1738]

With my humble experience with factories air cylinders, especially when all the torque is sideways and not directly inline with the piston rod, they are constantly breaking by the thread line. It’s recommended to install 2 smaller cylinders on opposite sides to balance the load. Thanks for sharing your neat beautiful videos.

[@ryanmayer4370]

So long as his roller skate wheel guide setup is rigid enough it should take up the majority of the torque and the cylinder should be fine.

[@crazycoyote1738]

Always a pleasure to watch your videos Josh. I'm still jealous of how easy the slag comes off of your welds. But yeah, your airlines are a lot more efficient now. And flexible airline is the way to go. Much easier to work with, much cheaper and for the same reason you stated, it's cleaner and not throwing debris into the mix. Still haven't built the hammer I bought plans for. I think later down the road for that one. A DaVinci power hammer is the route I'm going to go for now. But I still have a lot of other things I need so....it's all on the back burner for now. Anyway, great video as always! Keep up the great work! 👍

I will do an add on pdf with valve details and the pedal at some point as I've made a few more modifications I can add together. For welding high carbon to mild steel I recommend either 7018 or 309L electrodes with an arc welder. For MIG I'm not too sure but a stainless wire with pure argon may work better, you must pre heat the larger sections to get the best fusion 50-100 degrees Celsius is fine.

[@joshuadelisle]

I haven't, I just drain it after use. Sounds like a good idea though. Cheers J

[@MatthewTinker-au-pont-blanc]

Joshua, that was interesting! In my opinion, you contradict yourself when on one hand you advocate the more powerful push to raise the weight and then say that you try to slow it down to not damage the ram!I understand that you've made the plans that work well and that you don't want to change them! Your argument that external stops could fail is not a very good one! The improved short pipe mod is obviously very good. I was thinking that a reserve chamber just in front of the valve could improve flow as pressure in the line is fluctuating. Altogether, this is a very interesting design! Congratulations!! Regards

[@joshuadelisle]

I may not have explained my self very well. I only raise the weight slowly after forging entirely so it doesn't crash at the top. Between strokes I catch the return before it hits the top which infact also creates more power because it courses compression acting like an air spring of potential energy. External stops will definitely help save the cylinder but will take the wear of the hit instead. Depends on which is cheaper to replace and longer lasting. Cylinders and cushions are cheap as long as it lasts 12 months or so you can count it as a consumerble. Cheers J

[@MatthewTinker-au-pont-blanc]

@@joshuadelisle I think you explained things pretty well. I would like to underline the fact that you have built a really good useful tool! We disagree on a couple of points, these don't stop your design being very useful, getting out there and doing it is the most important thing! As you know, I don't agree about the upstroke stop! The other thing is the way round you have the ram, in my opinion, the upstroke doesn't need more power than the down stroke, it's not doing any work, the smaller effective size of the ram will make it faster, but will not give more power. I would love it if you made a tubular reservoir, about twice the volume of the ram to put directly on to the valve, I'm sure it would reduce lag even further!! All the bes, Matthew

[@joshuadelisle]

@@MatthewTinker-au-pont-blanc thank you. I worked it on the principles of velocity which is mass(weight) X acceleration. Your right that the surface area of the ram is more power in pressure but it's the speed that gives it more impact force. Like using a small hand hammer with a long handle is just as powerful as using a heavier hammer with a short handle. Cheers J

[@Ipschnug]

@@joshuadelisle Right, the actual work the cylinder is doing is on the upstroke, raising the 70 odd lb ram, and this is where the larger radius helps. The increased acceleration above what gravity gives is what helps on the downstroke. It's like swinging a heavy hammer, raising it is the hard part, but the faster you can swing it down, the more work gets done.

[@joshuadelisle]

Thank you so much!

[@Seanfrtd]

There are 2 more upgrades that I would do to this hammer. First I would find some way to make it double as a press. Second I would add stop switches to the shaft (either on the hammer or the cylinder). Then use the stop switches to tell the valve to either pressurize or depressurize, giving you the up/down motion without hitting dead top or dead bottom. Then attach the foot pedal to a valve to change the air flow therefore controlling the speed of the ram. This would also allow you to stop tapping your foot on the pedal and would reduce the risk of repetitive motion injury while allowing you much more control.

[@joshuadelisle]

I like that idea. Thank you. Cheers J

[@2squared4all]

Hello Joshua, nicely done power hammer. I was wondering only if exist a device that can regulate the number of strokes per minute and the strenght of a single stroke-

[@newlifeforvintagewatches2732]

Hi. That’s really good idea, but I’m wondering why you don’t used the rotory valve?????, if you install rotory valve then you don’t need to press the foot valve that much, only you have to press it like gas peddle in the car, depending to your air pressure and..... you will have speed and power. Actually you will have nice and fine control but powerful hammer.

[@unuensisable]

Quick question... the valve you install in this video isn't the one you show in the parts list. I know this is because you show more upgrades in more recent videos. But this seems to be your most basic setup. Bssic is what I am aiming for in my build. That being said... 1. What valve are you running in this video? 2. I don't have a solid round stock for the hammer head so what are your thoughts on my idea of using 3 inch tubing and filling it with sand? Sort of like a dead blow hammer.

[@joshuadelisle]

Hi Nate. This is the upgrade part 2 package. It's a 5/2 Push pull manual valve. Sand will absorb some energy compared to solid which will be better at energy transfer. You'll need a cylinder cushion or bump stop to protect the cylinder from over extension. All the very best. Cheers J

[@unuensisable]

@@joshuadelisle you're awesome.... thanks!!!!

[@copper7309]

Hey Joshua, I really like your hammer with its simplicity... in this video you mentioned you were through with making changing, then I see you are adding computer controls to it. It is hard not to keep thinking on making it better then trying it out. Some times I like making the tools to make an item as much as making the item. But I do have a question about the 5 way / 2 position valve you used in this video. I saw what you recommended in Amazon and did not buy it then as I was gathering info. I am ready to buy now . You have since changed the design again and changed the 5/2 valve to computer control . Do you still have the valve number that you used in this generation ? When building something it helps if you can start with something that others have tried and found out that it works. It lessens the price of the hammer by knowing what will work.The interesting thing is that you are really close to the control valve set up as a steam hammer. There are several you tube videos that show bits and pieces of the control linkage which gives great control with not using limit switches or computer. James Savage has built a combination De lisle hammer with a KZ 100 steam hammer linkage. There is also a video of the KZ 100 which a hammer with the steam hammer control ,it is Ken Zitur KZ 100 power hammer. James Savage goes over his linkage. It seems to be a nice hammer. Thank you for sharing your ideas. Robert Taylor

[@joshuadelisle]

Hi Robert. Yes all it was is a 5/2 manual push pull valve with 1/2 ports. Not common but can be found. You certainly could adapt it to use a steam linkage but I believe the electronic system is simpler, cheaper and minimal. Cheers J

[@Moondog-wc4vm]

If that's the ring of power, does that mean we need to throw the whole power hammer in a volcano when we need to get rid of it? ;-) Excellent video, very informative and I'm looking forward to the next one as soon as you can pump it out.

[@markkayser267]

Great design, is it expensive to build? I would like to get a set of plans for it if they aren't too costly. How do I go about that and what tools are required to build it?

[@joshuadelisle]

Hi Mark. It's very cost effective compared to buying an off the shelf power hammer. It does require a large compressor though and you must be able to weld at a high standard ideally using a stick welder with 7018 3.2mm electrodes. Build can cost £600 all in depending on your steel supplier. Do watch the latest video for more information. Cheers J

[@shanek6582]

Could you make it automatic by putting the reverse valve lever at the bottom of the ram travel?

[@joshuadelisle]

I'm going to put a small motor with a cam to push the valve in and out, and put a potentiometer mechanism on the treadle to control the speed. Cheers J

[@joaomarcelinobatista7661]

muito bacana esse novo sistema . BRASIL.

[@midclock]

Hi Joshua! I've just finished to watch all the three videos about the Power hammer. It's an excellent project, simple and effective. About the problem with the piston touching the cylinder head, wouldn't be possible to replace the foot switch with an electric one, which controls two solenoid valves? In this way you can shorten the pipes, avoid the "lag" problem due to large sections, and maybe you can implement a braking system which after a certain volume of air passed, closes the flow making the piston slow down. Then the airflow changes direction automatically. Maybe it raises the price a little, but I think that's a nice feature. Are you from Australia? 😁

[@midclock]

Partializing the exhaust will work for braking! I'm not sure that the rubber washer is making things better... It depends on how the cylinder is made internally. If the piston doesn't touch the head, then it should be OK. If the rubber makes contact between all the parts, it may even make things worse because it transmits the force to the cylinder, while the compressed air would.. Compress and absorb the shock! I'm just guessing :-)

[@joshuadelisle]

Hi. Thank you. Yes solonoid valves would work great and with an Arduino you could even corporate it into automation. I've considered using a solonoid valv e and limit switch at as a break. the cushion is working very well otherwise. I have another video coming out soon with further considerations for the design. I would love to hear more of your thoughts on that. Cheers J

[@midclock]

@@joshuadelisle sure I've subscribed, I hope to don't miss the notification! The cushion is indeed a good solution (simple and working), I'm a bit concerned about the fact that even if it absorbs the shock, it still transmits it to the rest of the cylinder, stressing it and shortening its life - in theory - in practice it can last forever, it depends on forces and materials. With an arduino you can change the behaviour of the machine, but you're not obliged to use such a complex solution. I'm sure that you can find solenoids working at 12 or 24v, with less than 1A. To control them you can use even a simple button and a couple of relays. What's missing is how to detect when the piston reaches the maximum and minimum stroke. This needs a bit of thinking, but I'm sure that there are diy solutions on the net. In case that you will need an help with the arduino in the future, I'm a software developer and i would be glad to help you ;-) See you then

@@midclock I'm sure a limit switch or proxy sensor would work well so the Arduino registers the maximum stroke before hitting the cushion and then shuts the valve to create an air cushion stop. Then needs to release when operating the treadle. I think I know how to code it to do that. But for now I'll use it till it breaks and that will give me a good idea of the longevity of the standard solutions. Cheers J

[@midclock]

@@joshuadelisle you're right, I didn't think about an external proximity 😩. For the future in case you need a solution: you can take as example the internals of a 🖱, the wheels are tracking movements with an infrared beam passing through some holes cutted into the wheel. You can do the same, using a band long the same as the full stroke, with one cut for each centimeter. With this solution is possible to count the beams arrived to the ir sensor,. Doing that, then you can partialize the air to slow down the piston, until it reaches the maximum point where the air direction is inverted. Good luck 😉

[@myownspiritlevel]

That upgraded air switch is $250 on amazon. How is performance compared to original one? We’re at $680 USD for materials so far. I’ve been gently bugging the CNC Plasma dude for two weeks now, practically begging him for a quote on the CNC’d parts. He cuts out massive rings for GE’s windmill housings, so I’m a small fry.

That valve shouldn't be that much. I paid £20 for mine. Keep shopping around for that. But it is much better.

[@victorreppeto7050]

Way cool design. I appreciate finding out from you that I can build a small unit using air power that I already have. How man cfm does it use? You could use the air twice if you use the air from the down stroke to power the up stroke.

[@victorreppeto7050]

Use a return spring to help the up stroke so it does not need too much air or use a shorter fatter piston for the return stroke.

[@joshuadelisle]

That's a good idea. My compressor is 14.5cfm, 150ltr, 3hp working at 120psi. Cheers J

[@victorreppeto7050]

@@joshuadelisle We can figure out what the cfm is. First the number of liter stored in compressor at full charge. 120*150/14.7=1224.5 liters. Now shut the compressor off and run the tool for 20 seconds. Now let's say the pressure dropped to100psi. 100*150/14.7=1020.4 liters. 1224.5-1020.4=204.1 liters in 20 sec equals 612.3 liters per minute. Convert that to cubic ft. 21.6 cfm.

Do you think it be possible to build the frame and body of the hammer and it be a in line tredel hammer then convert it the power hammer later

[@joshuadelisle]

My first sketches where a foot treadle hammer that has springs that take the weight to the point where the head is weightless, then adding a fast acting cylinder would replace the power of my foot and then some. That would work great but can be complex and needs more room than my workshop would allow. Cheers J

Not really. You'll need to know wether your weld is a good one or not as the forces this hammer produces can be Very dangerous if your welds don't hold up. Something to work towards maybe.

[@coryrudd9509]

I find it hard to believe that there is not a foot pedal that allows you to just control the speed/Air flow with a foot pedal that allows you the control without having to move your foot up and down. I only bring this up because I am slightly disabled on my dominant foot and while this will still be more productive and way "Freaking" more efficient than I will be able to imagine especially at my income. Maybe something like a "hybrid" pedal? Like an electric rheostat kind of thing that the further you push the pedal down the faster it pushes up and down for you? Am I being too demanding?

[@joshuadelisle]

I can adapt to be like a normal power hammer by adding a little motor with a cam mechanism to push the valve in and out. I could then attach the motor to my Tig pedal which has a potentiometer to adjust the speed which will also make the stroke slower of faster. Would you like me to do a video on it?

[@coryrudd9509]

Don't tell anyone I said this but your videos are better than porn. And HELL yeah, if you have a way to assist me on this issue I would love to see it! I was wondering if there is a way to use like a stepper motor or something that could go up and down but I haven't had the time to figure it out. I was thinking of something like the old slot car race tracks where it came with a gun like switch and the further you pulled the trigger the faster it went. Again, I just don't have the free time to even ponder this stuff right now. But soon, very soon. AND YES PLEASE PLEASE DO THE VIDEO.

why dont you use a switched cylinder or a separate switch so it just runs when you press the footpedal.

[@joshuadelisle]

I don't think I can control the pressure as well with a switch. Switches are generally on or off or very complex otherwise. I can feel the change with the mechanical one and adjust real time strokes for lighter blows or faster/slower reciprocation. Cheers J

@@tonytroyer9729 hi. The size of the tank will dictate the length of run time. The cfm will determine how long it takes to re fill the tank between cycles. Ideally you'll want a big tank and a powerful pump to fill it back up quickly. You should be able to get one like my mine new for less than £500. I got mine second hand for £100 and is easy to maintain/fix if there is a problem.
