This is my favorite design of the great DaVinci hammer. The hit rate is perfect and I'm going to look in different ways of increasing the strike weight. Springs would do it and I might go with a heavier head. Extremely well done. Thank you Sir.
I've been 'shopping' around youtube for which plan I'm going to use and the one on display here has my skin tingling to start building it... I like how you created the cam with wood and steel. I've got some 4140 2" round stock here that I'll use for the hammer; I think the circumference is less than your hammer but I've got about a meter of it so I can cut whatever length I need to get the desired weight. Many thanks for posting this; you just decided what my next build project is to become :)

Thanks for showing it operating, it is so disappointing to go through a whole video of someone showing their hammer but never seeing it perform. I think this worked out well, when you quoted how many strokes I thought that sounded way fast but seeing it work changed your mind. Thanks for sharing and I wish you much happy hammering
The way is put together it's just really neat. I like the Nautilus of the cam the neat little reinforcement things that he put around in different places to make it last. and I really like the way that the rail section is bolted on with spikes and it's just a neat design.

About 25 years ago i had a full time smithy on my home property. I had a Little Giant 100 lb. hammer that i bolted to a concrete pad that i poured. I wanted to make sure it would not crack, nor let the hammer pound itself into the ground so i made that footing 3x5 feet x 4 foot thick with a re-bar cage reinforcement. That hammer was still loud.
"I have neighbors who life quite close to me, so I build a POWERHAMMER! But I used wood so they didn't find out until it's to late." Just kidding, nice video.
It's cool to see the way people build things like this. I'm looking to build one myself but if I'm going to spend 500 dollars in parts I'd just buy one online. I'm not criticizing you by any means I think you did an awesome job
Watching this again. Still awesome. The easy way to test the spring is to get a "pull scale", hook it up to the spring, & pull till you can't anymore the read the poundage. That's how much it is
Overall the design is beautiful and fully functional (oddly in craft work form usually follows function). Well done. Thinking about that spring set up, wondering if a system of springs (ie add one when working larger/thicker material, remove one when working finer/smaller materials) may be a thought for you?
Thank you Randal! Different spring sizes would work well with various stock sizes. I'm hoping to make improvements in the future, (variable speed control, quick change of springs and or head change out.)
Thanks for the video I’m almost complete in making mine. What type of motor are you using. I put a DC treadmill motor on mine . It’s a 3 hp you thank that will be strong enough? Thank you
Thank you for sharing......... This set up, when tuned to what you are looking for (60# to 80# strike)....... is capable of doing what a $20,000.00 to $30,000.00 multiple ton press can do. Just looking at it....... with a little scavenging, and a little planning, That sucker is going to be an addition to my tinkering shop. 😎
Can you share any more information on the spring you ended up using? I am building a similar hammer to (hopefully) dish sheet metal, and I am going to need more force then just the drop of the hammer. Thanks for the video btw.
‘DaVinci Cam’ is actually a proportional mathematical ratio discovered by Greek mathematicians in the 1-3rd BC. It was appropriated by mr L DaVinci in many of his designs both failed and successful. But to call the ‘Golden Ratio a ‘DaVinci Cam or anything other than the Greek Golden Ratio or as many believe, ‘The Euclidean Ratio’ is inaccurate. Thanks for a great video! Looks like a hammer within my means!
Hey be careful a lot of the plastic/ fiberglass handles are not as strong as they appear. Ive found some to be mere pegs inside the steel with some rubber or resin holding it in place...very deceiving. Might want to go to a steel handle. Just a thought. But i like the set up...simple yet works...great job
add two more springs of that size, and consider a different drive setup. 14:1 is beyond extreme for a v belt, so perhaps a jack shaft with two reductions (4:1, 4:1) will allow the engine to transmit more power and without wearing your belts too quickly. alternatively, a tire drive works well, too, and allows some variance in speed vs. power with fine foot control. ie, the tire is 20" diameter, say, fully inflated but when the pulley presses harder on it the diameter "becomes" 19" or 18", lower reduction, more speed. the reason power hammers are so complicated is to allow variance in speed, stroke, and power. otherwise, you'd just have an A-frame drop hammer.
Hey Hey Ray - I love your hammer - I like how you wrapped the wood cam with steel - very smart. I've added you to my Blacksmith Power Hammer Playlist of Fame providing you full bragging rights :-)) Wish you happy hammering; Booyah!
Is the end of the sledge handle just stuck in that notch, or have you secured it somehow? If possible, could you put some basic plans in the description, a friend and I would really like to try and build this.
Mind you, if you want to keep your home address and credit card numbers private, avoid showing receipts from the local hardware store in your videos (5:30 mark)
Very nicely done bud but you could have done it out of metal for that price from the scrap yard lol still love what you got iv been thinking about building me one like this with multiple size hammers weights
It's a cool design, but there's a reason you don't see too many using that cam. Using springs for the downward blow means the motor has to work against the springs to raise the hammer, limiting the spring weight that you can use. As you already have a cam lifting the hammer, it's more efficient to also have the cam lower the hammer, which can mean more powerful blows. Of course, all blacksmiths have their own preferences, and if that design works well for you, no need to change it.
To find out what the spring resistance is ,”poundage “ , simply figure out how far the spring has to stretch upwards , then just mark that point on the side , then un-hook the hammer and lean it back out of the way of the spring then tie it up there temporarily , that bastard sure would hurt if it fell down and hit ya !! LOL O.K., now make a trip to the nearest sporting good shop and buy a spring action fish and game scale , and when you get back just hook the scale to the spring and pull up to the farthest point of stretch , then just add what ever the scale read to the 10lbs weight of the hammer weight and that will tell you just about what the strike force is , well pretty close anyway !! Good luck and damn nice first hammer build !! But , I’m just a ol’ dumb ass coal miner from the hills of good ol’ W.V. LMAO , GOOD LUCK !!!
They are a little costly ($200) but you could consider using a VFD on your electric motor to adjust the hammer speed without having to rely on a foot pedal tensioner, it would save belts, and be easier to operate.
Great video. I'm starting to get involved with metal working. I'm 56 with arthritis so it's hard to hammer for a long time and I want to build something very similar to this. Who was the guy you mentioned about making the Davinci cam I would like to get the details. Thanks for your video. Hammer Time😁😁
I think that's pretty sharp. The only negative I see is the height. Looks likes an uncomfortable stoop over time. But all in all that's a great machine. I'm sure you could experiment with heavier springs or hammers.
Hi Rey Love the Video , think i might build this one. But i have a dumb question. What are those metal things laying beside the back leg of the hammer . i have one but dont know what it is and dont know what to call it
I believe those are called creeper Clips they keep the cross ties on train rails from moving? Anyway they're made out of a good quality spring steel and I make tools out of them.
That's actually called a snail cam as it is shaped like a snails shell, I'm not sure, where you got the name Davinci cam, but I've seen these built before for various functions, one of which another person used it to drive their power hammer.
This is my favorite design of the great DaVinci hammer. The hit rate is perfect and I'm going to look in different ways of increasing the strike weight. Springs would do it and I might go with a heavier head.
Extremely well done. Thank you Sir.
Awesome job. This is what RUclips should be.
What? You dont like the dancing and singing?
I agree. This is a quality video.
I like the design. Simple & effective.
strap a section of 1.5" rod to the face of your hammer and you can get a more aggressive hit as well for drawing out! GREAT JOB!

Ray you may try a old truck hood spring for more power on the down for the hammer, Helluva job Sir I really like your design thanks
Thanks Tracey. Check out my power hammer update video where I added a larger spring. ruclips.net/video/O46cTYgOWKA/видео.html

Thank you.
Awesome ingenuity mate well done 👍
A really good and informative video. I like it alot.
This is brilliant. I love the simple ingenuity! :)
I would like to build this. Do you have a material list. And what kind of motor and gear reducer are you using?
Pretty cool.. nice job.. works really well
Hi, I love the design and would like to build one myself. Have you got any plans, drawings for this one to download, free or for a fee?
The project looked very sloppy to me at the beginning, but when that started to hammer, man, I was totally impressed I have to say. Nice work!!
Pretty does not make anything work better. It's the Engineering, not the pretty that makes it what it does.
Very cool hammer!! I’m gonna scrounge up some parts and get started on mine.
Thanks for the video I’m almost complete in making mine. What type of motor are you using. I put a DC treadmill motor on mine . It’s a 3 hp you thank that will be strong enough? Thank you
I'm using a 1hp motor which has been plenty powerful enough.
Very nicely done I might have to make me one

It is definitely a great tool at an affordable price, but it doesn't appear to offer the same precision and verity of function as a hydraulic press.
Very nice. I may build 2 separate types. One being the hammer you built. Really nice!
Can you share any more information on the spring you ended up using? I am building a similar hammer to (hopefully) dish sheet metal, and I am going to need more force then just the drop of the hammer. Thanks for the video btw.
I saw in a previous heleve hammer video where the guy had put a spring towards the end of the handle aswell, nice hammer
Also what is your rpm
Nice job. That is an ingenious piece of work... Thank you for sharing.....

Ray, great job. I'm beginning my power hammer and I have a question. Did you have to reduce the size of your cam from Mr. Rabjohn's 20 inch template?
Thanks. I used a 18" cam because the hammer handle is shorter than on Rick's machine.
@@RayFromTheHayclan Thanks again, Ray. I too am using an 8lb composite handle sledgehammer.
Way to go great build I built my power hammer as well definitely a fun project.... keep up the good work!!

So the motor idles while not pushed down, and then the pedal tensions the cable, and starts running?
Yes, that's correct.
