- I have a little bit different video this week. I talk about how my home made power hammer works, what I used to build it, and generally how it came into being.
If you have any questions that I didn't answer about how the hammer works, or how I built it, please feel free to leave those in the comments below and I will do my best to answer everybody's questions.
If you want to see more of what I do, you can check out my other social media on Facebook at northernforgeblacksmith.
If you want to reach out for commissions or questions, or if you want to see what I have for sale you can check out www.northernforgeblacksmith.com
All that and no demo?WTF?🙄
That's what I was thinking
Same here. How disappointing!
yes!!!
What a turd...it prob doesn't even work well, guess we'll never know
I watched that whole video just to see the design work!
Very interesting. I would like to see this hammer in operation.
Thanks, you can see the hammer running in most of my videos.
thumbs up when you show it working.
very cool design, thanks for showing
Thanks!
Wow that's very interesting. Hopefully you get great use out of it for many years to come my friend. Can't wait to see more videos soon my friend. Keep up the great craftsmanship and hard work my friend. Forge On. Fab On. Weld on. Keep Making. God Bless.
Thanks! One of the beauties of building it myself is that I know exactly how to fix everything.
Looks great
Thanks!
Yes, it will save you time and energy, drawback with the DaVinci cam design is you can't control how hard it hits, only able to control the speed. The springs being closer to the pivot point isn't a big problem, lose a little bit of leverage, but, not stretching the springs out of whack, good decision there. I like the extra outlets, could run a blower for the forge off of it, a grinder, or whatever. Maybe somehow make the anvil height adjustable for taller material, or the cam and hammer pivot. That would be an interesting project.
yeah, you landed right on the 2 biggest down sides with this style. I wasn't worried about not being able to adjust how hard it hits, since my main reason for building it in the first place was to be able to save my shoulder while breaking down springs and other larger stock into smaller materials before going to the anvil.
As for adjusting the anvil height (or pivot height maybe?), that was something I didn't think about until after it was built. Right now the hammer and anvil are perfectly parallel on about 5/8" stock, but are definitely close enough that I haven't ever had any issues from 3/8" all the way to 1/2".
Brilliant, that's my sort of build. Love the motor drive/disengagement, I did similar years ago. If you made your anvil adjustable in height but still keeping it robust, that would
overcome your problem when working on thicker material. You could build up a selection of various height anvils just to slip into place when needed. Love the finish, as is.........Tony
Thanks. Christ Centered Ironworks has a design similar that actually moves the pivot point of the hammer up and down to achieve the adjustment. I think if I ever give this design adjustable height I will do it by making thr top of the anvil interchangable. Then I could add different tooling shapes too.
That's interesting video my friend big likes 🤠👌👍
Thanks. I'm glad you liked it.
Looks good. A lot of planning. I'm surprised the bicycle wheel takes the punishment.
Simce the hammer and cam aren't actually connected together, the impact doesn't really come back to the wheel at all.
Thanks for the incite im from
Aus🇦🇺 and just starting to set up my own back yard forge . Next step is one of these ive been over so many videos on how to DIY a power hammer . But for what im going to be looking at doing this one might just do the job. Hopefully by the time im making it you may have made some more changes and have a rough blue print i may be able to use for more assistance. Cheers for the video looking forward to more .
Thanks, this hammer mainly came about because I already had or could easily get nearly all of the parts I needed to build it. If I had had to buy the materials, I probably would have gone with something like the clay spencer tire hammer, or maybe the Christ Centered Ironworks beam hammer.
Best of luck as you start your blacksmithing journey. If you have any questions you want to ask, feel free to go over to my Facebook page and shoot me a message.
Just found your channel and Subscribed. Very interesting video
thank you very much!
I was fast forwarding to see it running!! Nice build however
Nice .
Addressing the striking angels problem shape the striking hammer to a Narrower surface
thanks. I have the hammer spaced so that its perfectly parallel at about 3/4 up from the anvil (so 3/4 in thick material) and the slight curve on the hammer head does a help to compensate for the small angle change on thicker and thicker material.
We don't get to see it run after all that, WTF
Aqui no Brasil, fiz um do mesmo jeito, funciona bem deixei com regulagem pra 6 batidas por minuto
Just want to question you said your major failure point was at the cam is that the wood giving out under the pressure of the hammer hitting?
I wasn't giving out from being hit by the hammer, because the cam rotates out of the way as the hammer comes down. It was the pressure of trying to lift the hammer, that I suspect was not being evenly distributed evenly on the roller bearings, that caused the edges of the cam to split. The steel band around the cam was able to distribute the pressure and prevent the second cam from splitting.
As long as it works that what matters , did you just free hand the metal so called wheel what size would it be ? Cheers Andy Australia
I assume you mean the cam. I used a combination of measuring a freehand. The sizing is based on how fast I wanted the hammer to strike and how high I wanted the hammer to rise. then I drew a circle on the wood, followed by the second larger circle. I calculated how much increase in size would need to happen per section of the cam and made some marks then freehanded the curve between the marks.
Would have been good if we could see it working ?????
Any way to do something like this that doesn't require a motor.? Maybe gravity and pulley operated?
You can make a treadle hammer that uses a spring to raise the hammer, then foot power to bring it down.
Or if you have a running water source or enough wind you could set up a water wheel or a wind mill to power the rotation.
@@northernforgeblacksmith I like the spring idea, I'm going to toy with some designs
Thinking about building power hammer as I can not afford already built one
building a hammer is a great way to go if you have the tools and materials to do it. It will also give you a great appreciation for figuring out how the hammer works.
How is the bike wheel attached to shaft driving the cam?
The sprockets of the bike wheel are welded to a reducing coupling which is then welded to the bolt that functions as the drive shaft.
@@northernforgeblacksmith How did you ensure they were concentric?
Also, what size reducer and I am assuming it’s black pipe?
I eyeballed it. The reducer was 2 inches on the large end so it would fit over the smallest sprocket and that helped line everything up. The smaller end is either 3/4 or 1 (I don't remember exactly) since it was the smallest they had with 2 inch on the other side.
@@northernforgeblacksmith does it wobble a lot?
It wobbles a bit since it wasn't all perfectly straight when I welded it, but it doesn't flex hardly at all.
i want to see it running
You can check out almost all of my other videos to see it running.
y funciona o no ... ninguna demostracion ? dedo abajo
doesn't the hammer strike at an angle when there's something under it? does that not matter? I'm only curious, I think it's pretty neat.
the hammer does strike at a bit of an angle depending on the thickness of the material being worked. I build this one to strike flat on about 3/4 thick, but change in angle is pretty minimal for anything from about 1/4 to 1 1/4.
I have a question. Does it really work? Know demo.
it does work. I didn't run it in this particular video because this was done last winter and it was too cold that day to run the forge (tank freeze-up). You can see the hammer running in many of my other videos.
Hi. What is a weight of hammer head? 10 or 12 pounds?
I would have to back and look through my old posts to be 100% sure, but I'm pretty sure I used a 12lb hammer that got made heavier by welding it to the steel arm.
How well it works?
It works very well. You can see it running in many of my other videos.
What link for the demo ?
I use the power hammer in nearly all of my other videos, but here is a link anyway that will take you to a video where I use the power hammer.
ua-cam.com/video/p2NnUwfufD8/v-deo.html
Does it work.....can we see ?
it does work. you can see it running in almost every other video I have uploaded.
Does it work
It does work, you can see it running in most of my other videos.
Didn't show it running,, I feel cheated
Those are 4 hole flange bearings not pillow block bearings partner. Taking nothing and making something, cool. They say, it's not what you have, it's what you do with it.
Thanks, I didn't realize there was a different name for the bearings when they are mounted this way. I just thought they were a different shape of pillow block.
Why not show it running.
Thank you for asking instead of being rude. This is one of my older videos, and the day I recorded this it was too cold to get the forge running (tank freeze-up) so I did not have it running. You can see the hammer running in many of my other videos though. I do have plans on re-recording this video with a demo of it running. I never realized it would cause so many people to be upset.
Probably rusted shut
Are you fucking kidding me?!?! I just watched you talk about it
Why make a video of something that you never run
Not sure what you mean. I use this power hammer all the time. Its been in all of my last 5-6 videos.
@@northernforgeblacksmith Oh my goodness he means why didnt you turn it on during your walk through of the hammer... so why didnt you?
Pretty simple. Forge was cold and it was too cold outside for the propane that day, and its too hard on the hammer to run without something to hit.
@@northernforgeblacksmith ohh okay gotcha, thanks for the reply
WTF you can't show it work.
چقدر حرف مفت زدی....
Does it work or is it just bs
It is fully functional. You can see it running in most of my videos.
WTF turn it on
How dare you not give us a dimo That Sucks!!! I couldn't wait to see the dam thing run!! It looks like shit but I was gong to give it the benefit of the doubt!! WTF
Less talk. Turn it on
Totally wast of my time watched whole video n didn't get to see it run
Hablaste tanto al pedo y nunca probaste tu aparato
I know you're proud of what you built but you did all talking through the whole Process but what you're getting do is show it functioning come on man you do more talking than you do actual functioning people want to see something work when you make a A video show it working don't just talk us to death
I'm gonna guess I'm not gonna build one. Yours don't even work
Doesn't work. If you're going to criticize you should only do it in something approaching passable English.
"Doesn't work"!
If you are going to criticize you should only do it if you can come across as someone who doesn't live in an old shack way back up in the hills of Dumbshitistan.
English is something with which you might want to get acquainted.
