Did the sand get compacted after the first drop?

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.

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

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.

The silly amount of precision makes me so happy

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

Love it when science meets craftsmanship!!!

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...

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

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

A mallet wearing suspenders, perfect

this may be the most beautiful thing i have ever seen

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

Thanks Hackaday

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

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

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

Incredible work and inventiveness

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

Wow! Excellent work

I'm impressed

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

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

That was amazing. Thank you for sharing!

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.

Wow, I love it!!

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. 👍

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

Man that is an amazing mallet! Marvelous work

Nice craftsmanship. Just wow..

Nice presentation and explanation.

what a joy to watch. thank you

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

Outstanding creation, the hammer, and video!

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.

Bravo!! Simply amazing

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

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

This is over-engineered awesomeness! I love it.

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

Wow! Amazing project!

Awesome. Nice proyect and filming.

Very clever! And as always nice work!

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

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

Genius!!

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! 🤩💪

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.

Whaaaaaa. So impressive

Genius.

excellent 👏

Exquisite!

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.

Hackaday podcast brought me here

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

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

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

That is a very clever and beautiful hammer

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

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.

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...

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

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.

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

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.

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

Interesting.

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

Okay, crazy idea time - dead blow hammer with Mercury as the fluid and tungsten as the weight.

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!

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

Science! 😀

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)..

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.

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!

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

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.

I want one

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.

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

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?

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

I just looked for "make a dead blow mallet". I never expected to find a video on making the sexiest fluid dynamics bondage mallet in existence.

ok youre so amazing x

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

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 :-)

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!

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!

00:14:36 Shots fired lol.

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.

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

Amazing work how can I get one how much

13:50... wait, wait, wait... it's not bad enough that you're already show us all up with your superior wood working skills, but you actually made freakin' BUCKLES for the leather straps? Come on... that's just not fair.

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

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

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

Instant subscribe. I call for a collab with Uri Tuchman.

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.....

😍😍😍😍

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.
