[@RonCovell]

Karl - very clever design, and simple enough for any fabricator to build!

[@blainedyck3836]

It’s nice to see that your showing people that anyone can build something from scratch out of junk with simple tools even if you have to borrow a tool to finish it off . Great job thank you

[@1nvisible1]

* I like a power hammer that doesn't crack the slab and rattle my kids' fillings out.*

[@jakefromstatefarm9721]

You give people to much credit. Most can’t even change a tire.

[@jimmywhitlow2012]

​@@jakefromstatefarm9721 yep, most don't know the difference between their azz and a hole in the ground.

[@John-v2d3b]

Does it really matter how good someone is. If Karl can inspire them to give it a go isn’t that the ultimate outcome!

[@elo1031]

Your videos never get old man… let alone figuring out kits for the small garage!! Let’s goooooooo!!

[@DanHancock-e7o]

Thank you for the instruction video on this hammer build. Nice Job! Keep them coming Karl.

[@MrParacristo]

I am sooooooo looking forward to attempting a build like this myself. I have a buddy CNC cutting out the bead roller for me right now. So a scrap power hammer sounds like the next tool build for my shop! Thank Carl (JapHands)

[@harmlesscreationsofthegree1248]

Nice build, very neat and simple! You say you’re not an engineer but there she stands, and she works well. You have great intuition and a very competent set of hands. Those two things are better than any degree in the real world, in my experience.

[@georgeezzell4474]

You blow me away. Is there anything you can’t do. I was as excited as you while you were building this thing. I love this channel it gives me inspiration for my projects. Keep it up.

[@ralphalvarez5465]

Your skill with a torch is incredible and the build of this machine reminds me of stuff that my dad used to make. He loved to fabricate and you have that same passion towards the build.

[@jej_]

Karl, you are such a wonderful person. Sharing your enthusiasm, skill, knowledge with the world -- thank you so much.

[@jorgemercatali9319]

Agree 100 % !!

[@thom17043]

I really appreciate both that you make the work of metal shaping approachable as well as making the entry to it - by making your own tools - approachable. In your "storytime" segment, you said a number of times about how you were in awe of metal shaping for a long time before you had a chance to take Christian Sosa's class and actually give it a try. I think a lot of people out there are at that point - and many never get past it. I give you a lot of credit for showing people that doing these things are attainable and it is just a matter of making the effort.

[@burgundyexpress]

Brilliant work, Karl. If you add a coolant feed and catch-tank to your pillar drill your drill bits will last 10 x longer. I use a vibration pump out of a domestic espresso machine - they are very cheap. You have inspired me to build a power hammer now!

[@jerrymontilius7977]

You make a soul feel that you are talking personally to him individually. I is a special people skill that makes one feel that you are good friends. Thank you so much

[@gregjobson4844]

Nice work Karl, another machine to build for my workshop. just in case you dont know you can rotate the clutch mechanism on the front of the motor by loosening the bolts that hold the clutch assembly to the motor then you rotate it so you can orientate the lever to suit you foot linkage. Cheers Greg

[@MakeItKustom]

I’m Didn’t know!! lol would have been helpful

[@santocominos3252]

Built a bead roller modified from your design, not finished yet, want to build a power hammer similar to Steve Shepards Petingal hammer, and a pullmax type machine, lot of work before I can get to a car, but you're an inspiration.

[@GreggFesto]

Fantastic Job Karl - Thanks for sharing

[@rasmuskruger3179]

Ripper💪 That's what old school is all about. Using your head and hands rather than your credit card is such an important yet forgotten skill. I can only inspire my son, Good to know, there is someone doing that job on a bigger scale. Good onya 👍

[@chrismawby6241]

I've thought about making my own tools for a long time now. just watching these series of tool builds has made my mind up to get off my ass an just do it

[@michaelguinn5736]

Afternoon Karl... Ingenious!!!! What is so righteous is when you & a customer walk into your shop, they see the equipment YOU made to do any given job!! Kudos to you!!

[@MakeItKustom]

Making tools is a good way to figure out how to use em 😂

[@sgntbilco]

Awesome build. As a dyslexic, I can really see how this can be done without a plan or blueprint. To make something like this out of scrap and off the cuff is right up my alley.... just love it. 🙂👍

[@BuildNStuff86]

Man when you pulled on that clutch and it started hammering… I think I smiled as much as you did. Awesome build!

[@MakeItKustom]

Hahaha 🤣

[@geneschaffer4123]

Loved this video! Thanks for staying off the mill & lathe! Junk Yard Wars baby!!!

[@jdwisdom9433]

This has been an inspirational offering on how to turn previous mistakes into triumph!! Thanks, JD

[@marca5883]

One of my favorite of your videos so far💚🇬🇧🌱 love how you've kept it simple for us poor folk who don't have lathes & CNC... It's great seeing you work it out as you go, Genius at work! Thanks Karl👍

[@timr.3108]

Wow, I'm blown away! From the title of the video, I thought you were just going to assemble a kit. Probably one of your best videos. Love your tool making. You're also pretty dam good with the gas torch. Keep up with the great content.

[@MakeItKustom]

Thanks Tim it was fun to make!

[@atonefew]

Great work love that you did it using simple tools too !

[@larryreece1403]

DUDE! You are an inspiration! After taking the class with you and Christian, I was feeling like "how can I justify buying a Pullmax?" (I loved that machine) I now have my answer. Challenge accepted! I'm going to build one! But I will use my lathe!

[@MakeItKustom]

Awesome Larry!!!! I know yours will turn out amazing

[@Steve-pk4qk]

I've been working with metal all of my life as a welder and eventually a Maintenance Manager with an Associate Degree in Welding Technology. Worked In Steel Manufacturing for thirty years. Probably seen and done everything he's done in some form or another. I'm always entertained and learn a new way approach to metal working projects I take on now at Seventy. You can teach an old dog new tricks!

[@ToolPros_BillGullatt]

You’ve done it again. I want to build one of these hammers. I am amazed how simple the mechanism is. Cranium Engineering at its best. Think it, build it!

[@MakeItKustom]

So much fun making stuff man lol

[@denniscliff2071]

You already are an engineer and a designer. Excellent work.

[@minnesotatomcat]

I bought an old farm site about 5 years ago and I’ve been steady picking through all the old wood and metal and everything else that people have piled up around here over the last 100 years and using it to build things and furniture and an ice fishing house and lots of other stuff. It’s fun to just let your imagination loose and challenge yourself to build whatever it is you need out of whatever you got laying around 👍 tell Brenda I says hi!

[@jacobsnider4549]

Carl, this is awesome. I’m a mechanical engineering student about to graduate with my degree next month, you did a great job designing and building this machine. Can’t wait to give it a go for myself and see how it turns out!

[@billgeorge7804]

I never tire of Karl's videos and I've been an engineer for fifty years. A master of keep it simple stupid that works beautifully. You can tell the quality of the craftsman by how tidy their work area is too.

[@richardsdennis]

Bill George I'm impressed that you with your fifty years as a engineer didn't try to impress people with your knowledge. You simply complimented Karl on his work and tidy work environment.

[@billgeorge7804]

Thank you. The truth is, I admire Karl's expertise in these videos and because he's still loving his work. Even with all of those years I take great pleasure in watching a rounded craftsman creating useful equipment from odds and ends. It brings back memories of being in the middle of nowhere, all you have is a welder-generator, a gas axe and a grinder with a pile of scrap to make something usable. What impresses me with Karl is his ability to do the same thing, employing basic tools yet still produce a polished product. Hopefully he'll start to get the recognition he deserves by reaching a million subscribers.

[@andrel3]

Karl, I have been waiting for you to make this video. I’ve been wanting to make one of these for years.

[@Kan3dainterceptor]

It's so inspiring to see how Karl is happy and excited by his work)

[@hickeyskustomresto]

Thanks Carl, I've been building one in my head for awhile, I think you've answered any concerns as to whether it would work. Cool build. I will build one over the summer. Cheers

[@kenstevens5675]

Nice project, I like that you didn’t make it too tall, it’s easier to control the metal that way. Thanks for sharing.

[@gizmodietsch3922]

Great video!! And even better idea to call out other great fab folks!! Recycle, repurpose, reuse! Make tools!! Again, great stuff here. Hey Brent, jump in on this too!

[@bruceperron3796]

I have that exact same motor with pedal,I've now got a plan after watching your video,thanks a ton. Great tutorial as usual.

[@DuckyHunter812]

"It's a little sloppy, it'll work fine" Channeling your inner Dan from DD Speed Shop 🤣🤣🤣 Joking aside, this was a very inspiring build. Thank you!

[@billarroo1]

Very smart man, your idea worked very well. I was smiling the whole way through this video !! "Keep on keeping on" THANKS

[@chuckster6513]

Hey Karl, Really great video ! The darn thing actually does what it was built to do. Some of the vibration may be eliminated by grease in all the moving and sliding parts as well as some heavy gussets within the C frame. If you decide to add the gussets, do not just weld them in the center of the tubes as they will cause the area you weld them to to flex and crack. You can add thick pads that cover a large area to affix the gussets to or weld them to the outer sides. Great job man.

[@alleyoop1234]

The best and easiest way to gusset that would be to use the same 4x6 tube

[@richardsdennis]

I believe he knows all that 😂😂😂😂

[@blainekoch5018]

Keep it up Karl! I’ve been watching from the beginning. Never disappoints.

[@ameurezarzori4243]

I am from Algeria, I work as a mechanic, and I learned a lot from you. Thank you. Nice content. Keep going

[@jorgecardona4901]

That thing turned out a real winner! Love it …thanks

[@fredhoffman1017]

Thanks for making this video. You have inspired me to make a power hammer like the one you made. I greatly appreciate and admire your ingenuity and resourcefulness. Thank you.

[@joeybobbie1]

That really turned out Great. You really Hammered the Engineering.😁. I was wondering how you were going to get the Up and Down Motion for the Hammer. Like you said, you don’t need the Hammer to go very far in it’s movement. Plus you added the adjustment on the bottom. This is a Great Project for the do it yourself type Person. I think I will get some Metal together and make one. I have already made a nice 2” Belt Sander almost just like yours. Thanks for all the Work you do making these Videos. 👍👍

[@russtuff]

Somehow this channel continues one up itself every week 🤘

[@alleyoop1234]

Hey, thanks very much for all you do Karl! Hope to meet you at a car show this year

[@scottsprague9974]

Thanks now I know what next weekends project is. Every cool.

[@homemadetools]

Great work. We shared this video on our homemade tools forum this week 😎

[@jessehenry9152]

My favorite place to find parts for projects like this is farm supply stores. They have all kinds of bushings, sleeve, pins, and bearings made to slip together in the three point tractor hitch section. Love videos of making stuff from junk because I definitely don't need any suggestions or help spending too much money!

[@MakeItKustom]

Yes! That’s our “princess auto”

[@jessehenry9152]

I actually clicked on this video looking for ideas to use a clutch motor from an industrial sewing machine. I was stoked when I saw the motor on the table. So two tubs up for using your time and money to provide me with a proof of concept!

[@shotsrodder]

Your enthusiasm is contagious 😂😂 nice job Karl 😎

[@kyronwagner9015]

Watching this video just gave me a great idea for a project on the farm. Thanks Karl

[@grantdesigns350]

Fair play, I made a planishing hammer with a air chisel after watching yours, but I'm loving this, can't wait to make one. Love a challenge.

[@ddoherty5956]

I love that big drill bit, awesome 😂

[@vandalsgarage]

Proper job! Great video. Simple build, inexpensive parts, literally anyone who has the skills to use one of these sould have the skills to duplicate the build. Also, nicely done on the shoutout to Sosa Metalworks. Your vids are _always_ clear and concise. I don't have the time or patience to sit through a long-winded, multi-part series on how to make a bushing, which is why I stopped watching several other channels that I won't mention by name. 😇

[@janettehill8544]

I can empathize with your machine building excitement. I have been working on a 20" disc sander. More for wood working then metal working. It's machine building none the less. This is mostly made out stuff I have on hand as well. Your hammer is awesome. I have seen pictures of the pull max and Yoder hammers, but haven't fully explored the mechanisms that make them work. Great stuff!!

[@JSBriggs]

Thanks for sharing the passion. Its contagious.

[@That70sChannel]

Love the Macgyver Pullmax! "I'm not an engineer. . ." Actually, you are. Engineering predates university degrees.

[@MakeItKustom]

Haha I guess that makes sense

[@elo1031]

🔥 Underrated comment!!! 🔥

[@santocominos3252]

thank you so much, I finally understand completely how a pullmax works including the adjustable stroke

[@MakeItKustom]

You’re welcome!!

[@slashsplat]

Very well done. You are an inspiration. Thank you.

[@philipashmore]

As for the pulley ratio, the PI's cancel out so 8/2 = 4/1 mechanical advantage. You've given me some ideas! Thanks man.

[@-Mike-69]

And this is the exact reason we keep all those little bits of scrap steel. Very interesting build Karl. Probably not something I would make, however. You could easily take that mechanical movement and use it for ??? That's what's nice about being able to look at a mechanical object and see how it works.

[@monk8235]

1:01 - after being down in "the States" - wait, what? Always a pleasant surprise to land on good CDN metal fab content!

[@charlesmcdowell2801]

Love your enthusiasm and creativity

[@donaldlawton7384]

That's flipping amazing👌👍👍👍👍!love it! Thank you soo much!!!

[@Mudlobsta]

Maaaaan, great video!!! I love the “dreamer” fabrication techniques!! You may not have a piece of paper that says you’re an engineer, but, you actually are!

[@Tat2TankT]

Thanks for all your time n help bro just bought a Lincoln mig tig n stick combo welder n a disc grinder n a sander going to start working on my 85gmc short bed do my own dam work you n Halfass garage n gene Winfield r my effin hero’s thanks for sharing your knowledge and love with all of us bro 😎

[@rdspeedfab]

Dude… excellent. I’m currently building one myself. I bought the plans for a guy out of Arizona. Desert Hybrids. He’s got some good tools as well. Thanks for sharing.

[@davidmotoman4956]

Well there ya go, a Little bit of scrap some good Knowledge, Look at what you can create. Brilliant Job Karl, works like a Bought One!

[@CalicoRiot]

Cool video! I went out to the garage to see what I had, found a 240v 5hp compressor motor that spins at 3450rpm! Yeah, I think we can build a trash hammer with that. Just gotta figure out pulley sizes and what would or would not be overkill for this. Thanks for the inspiration buddy ❤

[@CheapThrills66chevy]

Great build Karl! You might consider adding a brace between the housings that contain the cam and the linkage to eliminate any flex and make the most of the up and down hammer movement. Can't wait to see the next installment.

[@MakeItKustom]

Ya it could be stiffer for sure

[@stevezwemer1262]

Love this kind of creativity and resourcefulness

[@aeromech8563]

Awesome stuff man. Love watching your work. Been an engineer for more years than i care to count and find myself on the opposite side of the world having emigrated needing to start over with a new workshop. Keep up the good work 🤟

[@fonhollohan2908]

" Google engineering degree.." That cracked me up! Karl thanks I needed that laugh!!! I believe the half horsepower should work fine for that purpose. Shouldn't need anything any bigger than that. Ya made yourself a descent little metal stretcher there bud..looks pretty cool. That tool will definitely come in handy for sure.

[@jamespriebe6408]

I built a copy of this little guy with a couple tweaks, added a 10.5 driven sheave from an air compressor which gives it a little more power and I ran flange bearings on the frame to reduce friction and make it run smoothly. I had previously billed too much larger power hammer of my own design with a 48 inch throat and a four horse DC permanent magnet motor, but there are some things this little short style machine does better than my other stroke machine.

[@rorypower544]

Amazing Karl Thrift looking forward to the dies being made! k

[@SR-gt350]

Man, you are so humble and awesome 👌 really enjoy your shows. So effective and efficient.

[@steveveness3829]

G'day from West Australia,😉 Amazing simple and efective build !!! The best kind me thinketh!!!!!!!

[@the4thj]

That's cool! I thought I'd have to buy some substandard thing from Northern Tool or Hazard Fraud and also have to run my compressor forever but this is so simple. Thank you for showing us all!

[@blkacid]

Nice clamps (welds piece to table)! I'll have to remember that one.

[@fredfleming261]

Cool I made a 2 x72 belt sander out of 95 % scrap and and old treadmill motor good stuff 👍

[@stumpymeadows5217]

You are so positive. I love it.

[@edricoddot]

Nice job Karl, this is a great tool. Thanks for your videos, I watch all the time.

[@ddoherty5956]

@Make It Kustom Hi Karl, just a thought with your chop-saw. If you set your first cut up, you can set your combination square up as a depth gauge to the side of the vice for any more cuts the same length to save holding the cut off against the stock. Hope all's going well for you. Dave👍🇬🇧

[@MakeItKustom]

Thanks Dave!

[@poolmotorrepairguyFL]

Jay the Florida pool pump motor repair guy. When Service Calls Longwood approved ! that was good info 2 see & know👨‍🔧good job !! Make It Kustom ,

[@rockingtm40]

Well done Sir, caught my interest right away and I very much enjoyed this project. I too love making things that work out of something else, odd ball material can be what you want it to be, and it’s so rewarding. Subscribed !!! Keep up the good work and be Safe. “If you can do something safe, once….you can do it safe every time”!!

[@johnjewell219]

Well done Karl love your self control.I would be diving for my lathe and mill at the first opportunity lol. I should have plenty of bits in my 60 odd years of accumulated odds and ends to make one. Greetings from east coast Australia. John

[@BoxcarsGarage]

Kudos brother for sharing that with us!!!

[@John_D75]

Hey Karl, thanks for showing us that we can make a power hammer with scrap! This is really impressive! Great job

[@MakeItKustom]

Most welcome John 👊👊👊

[@slicedbread9003]

Toggle mechanisms multiply force as you have deduced. This is why they are used on machines that require high forces. The one that I am familiar with is a hydraulic molding machine that uses the toggle mechanism to apply force to keep the mold closed as the plastic is being injected into it. Also good use of a commercial sewing machine motor. These motor and clutches are pretty sophisticated. Great job on the build.

[@adman6380]

Brent built a wild one years ago with a car differential, lots of ideas out there

[@Studebomber]

Wow Karl, this kicks ass. I would not have thought to use the industrial sewing machine motor or that the small stroke would work so well. This video also helps me to think through improvements I need on my el cheapo English wheel! Looking forward to making the mods and eventually building a hammer.

[@MakeItKustom]

Right on brian!

[@donbell8187]

Karl, you know how to sharpen a drill! Nice work! And not "should have been a mill wright", you are one.

[@paulhedman7387]

This is so cool. I have no use for something like this but might have to make one anyway. I had the thought that if you used a 1 hp or larger motor you could double the offset in the cam. That would give two strokes per rev as the drive would go past center lifting the hammer and striking again on the return. It looks right in my head anyway. Mechanical advantage on both push and pull. Maybe double would be too much, I'd have to draw it out and build a little proof model. Anyway, thanks I love this sort of thing and don't do as much as I would like.

[@michaelsudak6559]

I love that you took time to love on your pup! I’d get so much more done if it wasn’t for needing to spend dog time with my buddies.

[@davidellison6571]

Awesome! Gives me hope! Who doesn't need more tools!

[@charlesloyd1970]

I use scrap when I can. I've made a ton of projects from left overs and they look just as good. Cleaning it up is what takes all the time.

[@1SweetPete]

That's awesome, I been thinking about making machines lately, so this is definitely encouraging

[@mikerichards6311]

Well I’m glad I listen to Dan from DD speed shop, like what you do like your work👍👏🏻
