Looking at the chips from the auger, and the tear outs on the various edge tools, an episode focusing on sharpening tech would help you along a lot. The metallurgy and tech is really interesting, but a sharp tool is only as good as the edge worked in. Now you're into good quality materials, you can really benefit from the attention to edges. Thinking contextually, the tools were huge investments, and the folk using them knew how to get the best out of them.

Hm... I think they've missed a little bit of the point of the system- DaVinci's drawing showed the cam acting on an arm at a right angle to the hammer, on the opposite side of the fulcrum- I think that was an important part of the design, since it meant that there was more mechanical advantage on the hammer and would require less rotational force. This would allow you to use a heavier hammer, possibly set it up with a longer swing, and hand-crank it without getting tired.

It makes the machine also more efficient, because the hammer can fall freely. How the construction is now the fall of the hammer is limited by the speed of the rotating element. It can be seen when it's moved very slowly. It's the same reason why in hammer mills the hammer is actuated at the end with and not from under neath. Also in very old machined stones where stacked on the hammer head to increase the weight without investing in expensive metal.

Also, the hammer shaft is dropping on top of the cam, limiting its free swing and wasting lots of energy striking the cam instead of the anvil. Operating the cam against the end of the hammer arm would drop the hammer more freely for better striking.

No matter how you shave the cam the hammer handle will always ride the tip of the largest radius down through the rotation. It's never really free to fall.

I love how when he said “alternative power source” the water wheel was in the background, nice editing effect

The handle of the hammer is hitting the wheel, which prevents the hammer from completing the swinging motion all the way. Shave down the part of the wheel directly after the drop off so that the hammer rests completely on the anvil (until the wheel turns and then lifts it up again). A better way of doing this would have been to put the wheel on the back of the hammer, extend the handle of the hammer, and flip the wheel around so that it pushes down on the handle of the hammer instead of lifting it (this would cause less stress to the structures and take less energy to operate).

@jarekmace1536

Principles of leverage. Placing the cam at the rear end of the handle would take more energy to lift the hammer head. 1 lb. at the end of a 3 ft. shaft has to be countered by a 3 lb. load at the end of a 1 lb. shaft for an equity of 3 lb.-ft. of load. However, it would allow for a longer swinging arc of the hammer, creating a stronger blow. It just means that you'd need 2 people to do the work, one on the anvil and one on the crank, without some creative and excessive gearing to transfer power from the anvil area.

Designing the cam... Would it also work to tie a string to a pencil, and then wrap the string around a disk? As you rotate the pencil back around the disk, the string would unwind increasing the radius as you draw. The "drop" of the cam would be the same as the circumference of the disk. The length of string would determine the overall size of the cam. But I'm just an old country boy, what do I know?

A good upgrade would be to add a spring, maybe something like a crossbow to add tension. Also use graphite to lube the whole surface of the cam and the joints

A better "upgrade" would be to move the cam to where daVinci actually had it, on the tail end of the handle on the opposite side of the fulcrum. When the cam is between the fulcrum and the head the handle will always ride the cam down through the rotation, because the "step" in the cam cannot turn from vertical (where the hammer head reaches its highest point) to horizontal (where the protruding part of the cam is out of the way of the handle) instantly. No amount of springs, heavier head etc. can change that fundamental flaw.

Why add something complex like tension to something simple an effective like a gravity hammer? Just add more weight/mechanical advantage, rather than having to manufacture spring steel or something else under tension that would degrade. Nobody wants gut or other bowstrings in a forge environment… unless you want to be replacing them all the time.

you could always try a foot pedal system like they used for grinding wheels when they sharpen axes and such...and possibly a leaf spring to help bounce the hammer back up to keep momentum up and catch at almost the peak of the cam so it can then be set and to have a control on the speed of the hammer

Hell yeah thank you lol

I built a similar hammer for my home blacksmith shop based on your design. I used innertube rubber to pull the hammer up to it's max swing height (instead of a cam) and a treadle to pull the hammer to the anvil with every step. It works pretty well but I ran into the same trouble as Andy. The hammer is limited by it's weight as well as it's ability to be dropped to the anvil in a controlled way. I do think that a treadle attached to the hammer handle with a cord allows it to be pulled with greater force than gravity alone. The davinci design was conceptualized, presumably with a massive hammer, for industrial use. Anyway, thanks for the inspiration! It's pretty cool and I wouldn't have such a fun tool if I hadn't watched your videos.

I'd like to see a video comparing your different tools and how much of a step up in efficiency each was compared to previous. like how much faster a bronze hatchet cut versus the stone one.

Love the video :D as a smith myself this is going to be a huge help because traditional power hammers are priiiicey and I don't have a dedicated shop for one anyway One adjustment I would suggest is to add a treadle so you can use both hands on the project rather than one on the crank Roy Underhill from the Woodright Shop on PBS made a foot powered treadle lathe once I believe (he's actually fairly local :D town or two over) but with your water wheel I'm sure you could even do that fairly easily with a belt and wheel system (akin to a car's timing belt) but a foot treadle would probably allow more precise work and modern power hammers use a foot bar to regulate the speed

A treadle with a flywheel would actually be awesome for this kind of hammer.

Could put some boards on either side of the sledge to keep it from moving side to side. Lash them outside the perimeter of the cam.

This looks really interesting and fun. Also am a bit horrified about this thing being connected to a relentless power source such as a waterwheel. I'd like to first make it quite a bit more sturdy and fault tolerant. Maybe add sliders on both sides of the hammer handle so it really cannot fall off the cam?

It's a fine first attempt to get an understanding of what works and what needs redesigning. Lots of room for improvement but a very inspiring project. I can imagine setting up a treadle with a flywheel to drive the cam disc, which could also provide a more stable and smoother turning axle.

Another thing that might improve this is making the cam smaller so that when the hammer drops it hits the anvil before it hits the cam. A lot of the 'oomph' is being lost to contact with the cam.

Nice. I’m about to enjoy the hell out of this

Just an idea: Why not exchange that hand crank for a pedal system? Then you got your hands free for moving around the metal that you might be smithing on the anvil and you drive down the amount of operators from 2 to 1. Love the video btw ^-^

Couldnt you increase the power by giving it a longer handle/move the anvil father from the crank?

I have to say, you’ve all gotten much better at using the tools you’ve fabricated. Especially your forging skills. You’ve gotten to the point where you add a flair to your projects just because you can

I love it allready, but don’t hit a metal ax with a metal hammer, use a large wooden mallet! You could break the ax otherwise.

If u enlarge the cam, also keep in mind the cam start point. It appears like the hammer is hitting the cam som when it drops so maybe adjusting the shap a small amount to ensure it doesn't happen. Maybe some oil or beeswax on the hammer shaft/cam/axles to reduce friction n increase efficiency too.

It warms my heart to see how far you’ve come in creating things. I noticed you properly hafted the sledgehammer by hitting the handle at the end and forged a quite respectable crank (including some decorative twists). In a few more years you’ll be an expert at so many things

Fascinating stuff... just to say given Leonardo’s mathematical turn of mind I’m sure he would have given a lot of thought and care to the exact curves of the cam geometry. Laying out a pretty good approximation of a spiral is easily done with a compass or trammel (after all the Greeks were using volutes on capitals two millennia earlier) and the smooth running of the machine is down to how the rotational energy is transformation to the hammer. When it comes to the mechanics of gears and leavers, the devil is in the details....

You know in the title it shows da Vince's hammer wheel. As someone who has built hi machine using a 12 oz ballpeen hammer. I made 1 mod to it. I ended up making the cam for the movement of the hammer adjustable up and down by screws so I could add shims basically. It actually worked pretty good. The problem I found was the release point to allow the hammer to fall and strike the workpoint. So I made another mod later. I used a twisted rope with a screw adjustable tension so I could increase strike force. Amazing what he had done so long ago. Fun designs to play with also. I've even built a cutie chunker entirely out of an old oak tree I cut down to test designs and to see how I could improve upon it.

The falling off the cam problem would have also been solved by sanding or filing a groove into the cams face. Gluing a second cam in place did a similar trick, as the space between the two formed a guiding groove. A lot of their joints in the frame could use a second dowel/nail could improve performance by redeffort lost to the frame twisting.

Working by hand makes you strong. It gives you a muscular frame. I prefer to hammer something by hand, to an automated process any day. I only use powertools when it needs to be precise

This is some of my favorite content. I bet Archimedes, Leonardo Da Vinci, and all manner of Indian or Chinese inventors could inspire new videos for the channel now that you're in the iron and steel era!

FWIW, instead of making the hammer head heavier, you could add a weight connected between the cam and the head. The weight could be on the end of a beam that pivots below the hammer's pivot, so both rise in sync via a rod that connects the two beams.

This looks wonderful! One you have an automatic method that should really help your project progress! Also Lauren, those nails look so pretty this episode😍

As a proof of concept, you've done well.. to take it to the next level and make it actually functional, there's a few modifications you'll need to make. For an external power source you just need to harness a water wheel or windmill, something to provide power to turn a drive belt. Then through various sized belts and pulleys you can increase the speed and torque to lift the hammer higher and faster. Clean, accurate holes with dense timber bushings (soaked in oil or wax) will give a smooth operation and reduce friction. To manage the speed of the hammer you need a spring-loaded foot pedal which will adjust the tension of the final belt, allowing the belt to slip when the pedal is released, and tightening it when it's depressed. To control the accuracy of the hammer through its range of travel, you'll need to snug up all the pivot and rotation points, (your current tolerances are too wide, allowing a lot of 'slop' in the system, and this is wasted energy). You'll also need a couple of guide rails either side of the hammer handle, just forward of the cam lifter. These rails will need to be made from a very stiff and hard wood (and also need to be replaceable) as they'll wear over time. Ditto the hammer handle and the cam itself. Once you have these additions, the final thing is to brace it and add a lot of mass to the base so it is solid and doesn't dance around your workshop when in use...

I loved rex's appearance. I saw the words come up for one frame and had to figure it out.

I have seen a few KZread vids of working Da Vinci Cam power hammers and what one guy did to increase the weight of the hammer is to add a spring near the head of the hammer.

Great video. It was very interesting and fun. Some suggestions though as far as potentially improving this device. -bigger heavier hammer -larger wheel for it to go up higher -playing with gear ratios so the wheel spins faster -add some sort of spring, bow or other tensioning method so the hammer wants to go down beside from gravity

very interesting to watch. I would love to try it.

Your couple's partnership is inspiring!

This is a popular first hammer among hobby blacksmiths. Add a couple of trampoline springs to the hammer handle for the extra bang. Also considered sheathing the outside of the cam with sheet metal for a smoother operation and to keep the two pieces of wood from wearing each other out.

Love the work and love the direction its heading! Little blacksmith thought for yall. Sadly I cant say im surprised with its performance. Cam hammers of this size tend to be more like a powered treddle hammer. Less physical work but more time. Something closer to DaVinci cam hammer that have been used in the past would be a tilt hammer. Powered by water they would swing a hammer weighing upwards of a 1/4 ton! While im not sure if water will pack quite a punch on this scale, but i am thoroughly interested to see the end result.

I like the waterwheel just chilling in the background...

Switching to the more modern axe head while hewing the log instead of while felling the tree is just golden content. Lol

If you can find a way to put a concave wheel on the lower edge of the hammer handle so that it rolls on the cam, it would likely help with the friction that's working against the spinning because you've got the entire cam rubbing against the hammer. The wider cam does help keep the hammer from falling off, but you could probably also have put guide posts on either side of the assembly as well

You could modify the hammer so that you can attach barbell weights to the shaft. That way, the force can be adjusted as needed. Also, a treadle would probably be advisable to allow the user to control the speed of the cam. I haven't read other comments, so someone may have already said this.

Niiice, cool to see a DaVinci build. I look forward to your next iteration of it. Heavier hammer falling a greater distance, also add a leaf spring or something springy to pull or push the hammer down, and hook up to a waterwheel for power. Also, would be nice if you get/make tools appropriate to the time period of DaVinci. Buy what you can, or close enough to the appropriate tools, or buy materials to make the tools.

For the hammer sliding off the cam, just insert some guide rails alongside the cam to ensure the hammer stays in place. The guides would also help ensure the hammer is hitting right where you want it too. Further, by using rails you wouldn't have to widen the cam, thus lowering its weight and making it easier to turn. That would also help keep your handle from bending so easily due to the torque of turning a cam that big. Also, you need to put a stop bar level with the cam or at least add some leather padding on the hammer handle. Or simply make it so there is space between the handle and cam at the point the hammer comes down. Otherwise the repetition of the hammer handle striking the cam will make the whole mechanism more and more wobbly as time goes by. Eventually even cracking the wood.

I just want to Complement them for how hard they work on each and every project and they are really great about their work and they don’t give up

You may have already made this connection because I’m a little behind on your vids but it just struck me that the fire that got your old workshop sort of simulates a natural disaster that sets back a civilization.

Wow. This is super cool

Every time I watch this I realize how important it is to be working with groups of people and for people to specialize in what they do.

You could add a pull down spring below or push down spring above the hammer handle as something to add velocity to the strike. This in turn could be made to lend adjustment as well.

Great work its a great bringing to life of this amazing design. I see that you took great care to in the building of this mechanism. I want to suggest this precautionary WARNING If the mallat strikes nothing and the hammer handle strike the wheel, then there is the risk that the wooden handle shatters and the mallat is released. Also, to increase the striking force to mallat, you can tie on the handle just below the mallat a sand bag to add more weight to mallat.
