Making a Crazy Wooden Dead Blow Mallet with Fluid Dynamics

[@bricklearns]

Did the sand get compacted after the first drop?

I shook the sand and flipped it over and back right before dropping it, I forgot to mention that in the video

[@L0U_ZER]

@ thank you for answering this, I was wondering this myself!

[@juswoodshop]

So cool! You are a badass.

[@mrsensable]

A lot of work for a hammer.

[@cfk-oz]

It would be really cool to see a collab between you and Uri Tuchman. The attention to not just functionality but also style; you both make such beautiful pieces.

Maybe some day.. I love his work!

[@mrsensable]

This is why I love KZbin. All the creative people expressing them selves. Wonderfull video.

[@markhedquist9597]

This is the second video of yours that I've watched now. My jaw was still in the floor from the first one. Yours is some amazing and original stuff! I haven't time for anymore video watching, as I'm already late to band practice. Will be difficult to focus with mental pictures of this incredible mallet in my head! So glad to find your channel and very much look forward to seeing more of your builds/ products/ etc...

[@beurky]

I applaud your ingenuity, engineering and craftspersonship! Well done!

[@MartinMurrayWoodDesign]

This is an amazing mallet. Brilliant execution and a fancy jacket.

[@jacobcohn546]

Such a clever concept with great execution, would buy one if I could haha!

[@DiesInEveryFilm]

That’s a pretty cool concept I like the overall idea. Thanks for sharing

Thanks!

[@snowbkid1]

Art, science, and educational. Your videos are so wonderful.

[@randallthelovehandel]

Wow !!!! machine shop, woodworking, leather crafting and making tools all in one video. You’re just gonna have to stop it man this is too good.

[@michaelsimpson9779]

The finishing touches, well done.

[@markkrick8602]

I truly enjoyed your process and artistic flair. I'm a bit late to commentary, You've earned my sub and like. I'm looking forward to more content!

[@alans1816]

This is such a great project! I just watched it again, and can’t believe I haven’t yet found the time to make a version of this. One day I will.

[@useitwice]

VERY nice! You are very skilled. Im subscribing. I cant believe you dont have more followers already

Thank you! Happy you are enjoying my content!

[@1ifemare]

That smooth sax jazz at the end is the perfect melody for such a sexy piece of woodworking. The amount of love poured into this piece is the essence of great art. We get 15 minutes of bliss watching raw materials transmute into a completely new creation... like watching a super time-lapse of plants growing and blooming from a minuscule seed. The idea is the seed, and this hammer an exotic orchid. You get to be the mother to these projects, giving birth to your thoughts and nursing them to maturity for god knows how many hours it took you to complete this. I guess what i'm saying is that i envy and admire you for that and thank you so much for sharing.

[@PPG9944]

That was very interesting. The almost American comment got me haha

[@zski03]

Made me chuckle too.

[@tomjkelleher]

Amazing design and fantastic video. I learned so much and laughed so many times 😊. I really like how you anticipated the technical questions and answered them so well. 👍

[@OpusX2010X]

Great to have a vid fro you again. Hope all is well. Amazing job!

[@sylvansmithy5262]

The silly amount of precision makes me so happy

[@nunya3352]

Love it when science meets craftsmanship!!!

[@slugbiker]

elegant design! love the tiny buckles you made to hold the leather cover.

[@creativespace3077]

Your mom has tiny buckles

[@airnashville3883]

Incredible work and inventiveness

[@colaptesauratus]

cool video! i've seen probably 4 or 5 different people making dead blow hammers, and yours was by far the most interesting one and the coolest end product. weirdly, none of the other hammers were wearing a sexy leather garter. i bet people will imitate your hydraulic model.

[@damianamejeiras8858]

Fabulous idea!!!!! editing musically a pleasure congratulations from Argentina from a subscriber!

[@draginator6]

Loved the video! Really enjoyed the design and metalworking aspect of the cylinders.

[@impulse0341]

Since it can only be used one way, finger grooves on the handle might make it easier to index blind.

[@cannonroberts5129]

Nice presentation and explanation.

[@thomas_vera]

Superb video, very educational! I really enjoyed the theory, then the tests and finally the demonstration. All this for a very beautiful and functional object, combining different techniques. You have a wide range of skills! 🤩💪

[@gregallnatt9464]

Just found your Content, astounded at your inventiveness and versatile skill sets. This broad range of skills is missing with today's apprenticeships. Won my sub no problem.

Thanks for the sub! Happy you are enjoying the videos!

[@Blade2Raiden]

As always a very interesting bit of engineering! Love your work, have fun using it!

[@miles67733]

I love your original and interesting ways in accomplishing a different take on what tools and storage can be. I just found your channel but I can easily tell that I will be interested in seeing you’re future projects and am excited that I get to be so early on in the growth of your channel. I look forward to having a front row seat on watching your channel growth! I also enjoy your mix of technical know how and nerdy humor you bring to your videos.

[@foxbat9444]

this may be the most beautiful thing i have ever seen

[@thomasbrubaker4627]

Nice dig. You’ll need six cylinders to be American. Cool mallet!

[@pjhalchemy]

You forgot the Sharps 4 barrel Pepperbox derringer but got the dig.

[@joepucci7719]

Outstanding creation, the hammer, and video!

[@TheGrantAlexander]

This is over-engineered awesomeness! I love it.

[@danLyoutube]

I actually already have a deadblow hammer with weights suspended in fluid! It's just that the weights are BBs and the fluid is air. This is incredible work. There aren't enough people designing new hand tools nowadays. Thank you for sharing, I'll definitely be making one for myself.

[@diegoguerra8736]

Awesome. Nice proyect and filming.

[@JackMoney]

This is a great build and cool design - maybe just tie up your hair and watch those sleeves on the lathe?

Thank you! and fair point

[@leonzantvoort6201]

This turned out to be a very nice hammer. But no music and no black screen would make this video one of the better ones.

[@gdpjm]

Love your videos, your tools are functional as well as beautifully made. Inspiration.

[@parjau4554]

Absolutely brilliant and a very absorbing watch. You are obviously extremely talented! I am shocked you haven't got more likes, or more subscribers. And it seems you have not put up a video for a year. That is a real pity - I hope it is not for a bad reason. I do love woodworking so I will be checking out your other videos (this was the first I encountered)..

[@weekendstuff]

Well, that's a cool build and explanation. Thanks for sharing.

[@ReneBang]

Nice craftsmanship. Just wow..

[@anandarochisha]

GOOD JOB ! I think You just reinvented the Hammer..

[@bastiatboi4510]

Amazing idea, im wondering about making a steel one where the tube of the head is one big cylinder

[@rabbi1991]

Man that is an amazing mallet! Marvelous work

[@MadebyWolfe]

BTW, your Facebook link in the header of your home page is not working. I love your stuff and want to see more.

I'm happy you enjoy my content! And thank you for letting me know, I fixed the link.

[@JohnSmith-pn2vl]

very impressive result! the leather stuff is new to me, nice content and entertaining! glad i found this channel :)

Glad you enjoy it!

[@imadethischannel]

Wow! Amazing project!

[@davidbarnett3732]

That was a great learning experience and a fantastic build. Well done.

[@EricMcWhirter]

Very clever! And as always nice work!

[@bronsonguidry1744]

The music is horrible, but you did such an amazing job! Very nice work, on the video and the piece. It's a work of art. Much gratitude for sharing this with us.

[@JLneonhug]

What if you have 2 one direction and 2 the other? Great vid. Thanks.

Thats a good question, I could easily try it but I didn't yet. But regardless, the way I made the cap isn't strong enough to hit with it

[@johnland7318]

Beautiful work, your cylinders are just like the hub mounted dampers used on the 2CV suspension, before shock absorbers where fitted in 1981

Just looked that up. Its a really interesting suspension setup!

[@johnland7318]

@ It is, independent, interconnected, height adjustable, long travel, soft ride, no anti roll bars, perfect for rough roads or tracks. The Citroen 2CV is fantastic design solution.

[@JustJimWillDo]

This is totally, ridiculously, over-the-top over-engineered. And I love it! And then the kinky leather harness? That's a 'subscribe' from me.

[@DrChattan]

That is a very clever and beautiful hammer

[@michaelsimpson9779]

Absolutely brilliant

[@meraj95]

Thanks Hackaday

[@jamesk7410]

Wow! Excellent work

[@geekazoid]

what a joy to watch. thank you

[@cchaos11]

As always very interesting. And funny too, love your comments. Thanks for the video.

[@tonyashby7881]

Amazing work how can I get one how much

[@emilalbu]

Is it overkill ? of course it is, Would i like to make one ? of course i would :) You do overcomplicated projects that are worth doing not just for the result but also for the joy of doing them. Also, i like the way you explain how you do different things, you don't go into overly long explanations but give enough details that we can understand how it works and how to make it ourselfs.

[@TylrVncnt]

Wow, I love it!!

[@pjhalchemy]

This video got my Sub! Most impressive design and build as well as your versatile tool collection. A diverse tool kit with some quality home made ones sets the stage for higher levels of learning and achievement, imho. Nice, simple test setup too and quite good videography throughout. Looking forward to the tool box completion. BTW, no need to be anything but yourself, you've got lots of chops...take it from a well traveled old geezer if you like. Hat Tip, ~PJ

[@gmcalabr]

I'm going to suggest that the sand test's poor performance at 6:20 was partially because the sand is already sitting on the bottom of the chamber when dropped and accelerates at the same rate (or faster) than the tube its in. In a deadblow mallet, the mallet changes position and likely accelerates faster (and in a different direction) than the mallet, bringing the sand to the middle or back of the chamber, making it more effective than in your test. Of course, that wouldn't apply to light downward chisel strikes, but not many people use a deadblow on a chisel. Still, your hydraulic setup seems really nice. I'm sure it still works better than a sand deadblow. I mean, the fluid is going to impart force on the head nearly instantaneously where the sand could take a small amount of time to force the mallet head back down after bouncing.

[@forkmonkey]

Was thinking the same thing - the sand cylinders didn't quite get a fair shake (ha) in the drop test because there was no acceleration faster than free-fall to shift the sand backwards as there would be in a hammer blow. Not to take away from the superb construction and cool concept - just being fastidious about the testing.

[@ynns1]

This is an ingenious tool that not only works as good as the best of them but looks better than most! You know, you could easily make the action bidirectional if you added a second spring on the other end of the weight, so you wouldn't have to mind whether you hold the hammer properly or not. Of course that may lessen the travel of the weight and thus the effect... Hmm, food for thought and maybe some testing? BTW, 357magdad would love this, wood, brass and steel are his favorite materials in tools.

Thank you! Yes thats true! Though it would make the hammer longer. I'm also concerned it may make it feel heavier to swing sonce it would resist to the swing as well. Perhaps the effect would be of trivial consequence though. With my design as it is, the rear cap is also not strong enough to take regular impacts. But all and all I do think it would be possible!

[@MrMEmEmEmEMEMEeeeeee]

13:41...where did you find those gorgeous handles?

Do you have an issue with my tiny pink pliers? Aha

[@nefariousyawn]

That is so cool. I was just thinking about a dead blow hammer that used liquid somehow, and your video popped up in suggestions. Obviously your execution is much more cleaver than anything I could come up with. Please don't breath in the solder fumes!

[@BiggMo]

So...(I’ve been thinking about you...well, this project that is), could a spring be used at both ends, keeping the cylinder centered to make the Mallet bidirectional? ....of course this would limit/reduce the available movement of the cylinder...wonder how it effect the function? Nice job, I love the artistic engineer in you.

I do think it would be possible! I thought of it but dismissed the idea for 2 main reasons. First, I don't actually need it to work in both directions and second, it would make the hammer longer for sure. Or shorten the travel as you said. But now that I'm thinking about it, I think there is also a possibility it would resist to the hammer swing as well. This effect could be a of negligible importance but it could also possibly make the hammer feel heavier to use. Could make it feel a bit like a shakeweight!

[@BiggMo]

@ - 😂 I remember those shake weight commercials- takes me back to my teen years and my immature imagination of what I was watching .... good times!

[@thadcampbell3563]

@ you could still get the same effect. if you shorten the internal weight by a few millimeters and reduce the diameter of the hole. Then it should have the same "feel" as a single sided dead blow hammer, but for both faces.

@@thadcampbell3563 although the resistance for the shock absorber may be the same, the mass is important and it is what activates the damper. So a reduce of mass in the moving weight will inherently reduce the efficiency of the hammer.

[@IncendiaryMedia]

This is beautiful, do you make these on Etsy too, or is this one of a kind?

[@jaquo25]

Wow, this is really cool. I got looped in with the toolbox video and starting to go through some of your other projects. You are a multidisciplinary adept, for sure. I wonder what if you swapped the direction of two of the cylinders? Would it be bidirectional but half as effective? Would it cause seepage past the O rings if you did?

[@space6707]

What is the exact point of the liquid?Isn't it the metal mass doing most of the work? I would also think that spring is helping a lot. Either way it's extremely effective, so gg.

Good question! The liquid is actually doing most of the work. It slows the movement of the mass which lets it move enough to absorb some energy but not enough to transfer energy into a rebound. The spring is only there to reset the mechanism for the next hammer blow.

[@space6707]

@ ohhh I see, thx for the explanation

[@ianmurrell209]

You have quite an original mind, then you also have the skills to match.

[@lmzanlucki]

That was serious work, it looks great and seems to work good too. And it's really nice to watch your videos, the "almost American" made me laugh, I had to stop the video for a while!

[@miles11we]

A mallet wearing suspenders, perfect

[@pablodana1512]

The single fact that you still have both hands and all ten fingers, dead blow me.

I've been woodworking for 12 years, sometimes the camera angels and lenses distort how close the blades really are to my fingers

[@YahushuaMessiah777]

How much for one of these?

[@sabkdb]

Is this model for sale?

[@wdnick]

Genius.

[@BiggMo]

Beautiful & amazing.... now go whack something. Seriously... your amazing.

[@robertgoff6479]

"...almost made me feel American" caused me to spit morning coffee. 👍

[@luisurbina5115]

I'm impressed

[@mikael3454]

Whaaaaaa. So impressive

[@maadmaxx123]

This is super cool. Love the idea and execution. Now I don't want to be the person to tell you how to do things but a safety thing to keep in mind. It's generally poor practice to have long sleeves while working with lathes and grinders, one mix up and your arm is going to be very sad. Stay safe!

Thank you! And yes, you are right. It's a bad habit

[@beurky]

What would be the theoretical differences between oils? Ie: what other oil did you think of using?

With different oils i could tune the difference in how easily the weight moves. Which would mean, a thicker oil could be used for hitting hard and a thinner oil could be used for hitting softly. It's probably excessive, but in theory it could be tuned as such. And I would have used remote-control car shock oils, they are sold in all kinds of weights and you can buy them in small quantities

[@bobseagull7600]

Bravo!! Simply amazing

[@bell7759]

Nice build! Would you be so kind to tell me which wood the hammerhead is made of?

yes, its made of wenge

[@samuelmellars7855]

This is one of the most overcomplicated, ridiculous and niche things I've ever seen. It took ages to build and is only marginally more effective than just buying a cheap dead-blow hammer. I love it! It's beautiful, effective, well thought-out (wonderful testing montage btw), lovely finish. The only thing that I'm less than enthusiastic about is the way the leather is attached, but I can see why it was done that way and there's nothing wrong with it! I need to get my hands on some wood so I can finish a few of the projects I have in mind...

[@MaffuH]

Another superb build, The leather ensemble look like it belongs in a fetish boutique ! Did you consider one larger cylinder, would that have worked ?

A single larger cylinder would work well I presume but it introduces a new challenge. The handle would then need to be fixed to the cylinder itself since it cannot go through the cylinder to be mounted like a regular mallet handle. I'm looking at trying it but it will turn this into a machining project more than a woodworking one

[@bradleytuckwell4854]

I want one

[@timromano7085]

Enjoyed this. Ever read Michael Ayrton's novel, The Maze Maker?

No I haven't

[@timromano7085]

@ It celebrates the inventiveness of the artisan.

[@damirlorca1298]

thats bananas!

[@Senfonikankara]

excellent 👏

[@MakingABetterLife]

I long to afford the time to problem solve and complete projects at this level. It just seems to be commission after commission on top of emergency structural work ATM. Love your content, and your brain :-)

Happy you enjoyed it! If only the overlap between the projects that brought in the dough and the fun ones was a little more pronounced!

[@AlainPilon]

what are you doing at 10:24? I dont understand what I am seeing

I'm turning the handle for the mallet

[@AlainPilon]

@ I mean the T tool thingy you are holding, how does it work? How is it called?

Oh sorry, that's a telescopic gauge. It's a tool machinists use to get a precise measurement of a bore. (you take the measurement off them with a micrometer)I like them for woodworking, they are more reliable than inside calipers I find and they can go deeper into a bore than digital/analog calipers.

[@AlainPilon]

@ Thanks! I am trying to get into machining, I own a Taig micro lathe, but I havent had much time to play with it. So far I am only using it to make brass knobs and I am trying to get a bigger one to do "real" work...

@@AlainPilon are you looking to get something like a 10" lathe or a real professional sized one? The one I got is an old atlas 10" lathe and although it isn't the perfect-dream-professional-lathe it had the benefit of actually fitting in my shop plus it was far easier on the wallet.

[@LgosseuxDbois-TheWoodpecker]

J'adore tes projets, ils sont vraiment trop compliqués c'est ce qui fait tout le charme. Une personne normale, comme moi, aurais juste pris une branche et l'aurais tourné sur le tour. Mais par contre ça aurait pas été un dead blow tiré tout droit de la science-fiction.....

Aha, Oui! Mais c'est la toute le plaisir pour moi!

[@LgosseuxDbois-TheWoodpecker]

@Ebenisterie Éloïse Mais je te comprends si bien. je ne fais pas de "Crazy mallet" Mais je me demande toujours pourquoi certaine personne utilise toujours des vis sur leur meuble. c’est quoi le plaisir de tout assemblé avec des vis? Et tu te dis sûrement c’est quoi le plaisir de juste tourné un maillet quand ont peu en faire un avec des chocs en cuivre a l'huile :))

[@TylrVncnt]

Genius!!

[@YahushuaMessiah777]

Will you make one of these for me?

[@dr.sawdust4278]

why is there a hotdog on your grinder? :'D cool video btw, nice explained

I only noticed that in the editing! Its a handplane shaving drenched in oil. I have no clue how it happned
