How-To Build a Metal Shaping POWER HAMMER From Scrap Metal / Pull max/Nibbler

[@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!

[@chazmodius1024]

You could connect a foot pedal to the clutch.

[@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)

[@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 🤣

[@DanHancock-e7o]

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

[@elo1031]

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

[@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.

[@DesertGeezers]

I couldn't agree more. Innate skills...book smarts....use what you have to build a better mousetrap.

[@tkskagen]

When it comes to Fabricating my own Tools and Garden Tractor Attatchments, I have always tried to sketch at least 4 variations (thumbnails) so I am able to follow our beloved "K.I.S.S." method in order to try different styles and techniques. Plus, when it is drawn, you always have an eraser to change anything before making that first cut of material! When it comes to "larger projects" such as your Recipicating Hammer, I visit my local Big Box Store or Grocery Store, and ask for a few "Pallet Slips" (cardboard peices that help protect the palletised goods) early in the morning after they stock shelves. You can NEVER have too many of these, as they also work splendidly for C.A.F.E. (Cardboard Aided Fabricating & Engineering) that we all know of. As I am only 14:53 into this video (so far), Zerk fittings will be your Best Friend to keep everything from seizing... Especially if you grind in a few (4-8) groves into the Vertical "hammer arm" without having to worry about Seals about ½" above the Zerk Fitting at "absolute bottom" of the throw.

[@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.

[@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

[@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!!! 🔥

[@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

[@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 👍

[@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.

[@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.

[@jej_]

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

[@jorgemercatali9319]

Agree 100 % !!

[@williamwhitman6874]

On my Craftsman table saw, the motor hangs off the back so when it pivots down, it tensions the belt automatically. So whynot do that here. Weld the bracket that came with the motor so when it pivots back, the weight of the motor tensions the belt

[@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

[@denniscliff2071]

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

[@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!

[@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!

[@GreggFesto]

Fantastic Job Karl - Thanks for sharing

[@artknowles2707]

BEAUTIFUL !!!!! PAINT IT !!!!!!! GO TO WORK !!!!!!

[@jvmiller1995]

You can buy cheap brass bushings to go into those joints. They are all over the net but even some tractor supplies. have them for a few bucks each. That would make it all run smoother and last longer, anyway I am only 22 min in. First time on the channel and liking it. I am so much a like.

[@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

[@monk8235]

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

[@Kan3dainterceptor]

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

[@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

[@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. 🙂👍

[@andrel3]

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

[@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.

[@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

[@ameurezarzori4243]

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

[@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 😂

[@alleyoop1234]

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

[@blainekoch5018]

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

[@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!

[@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.

[@fredfleming261]

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

[@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!

[@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 !

[@ddoherty5956]

I love that big drill bit, awesome 😂

[@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!

[@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!

[@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!

[@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.

[@slawnski]

Thank you thank you thank you!!

[@homemadetools]

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

[@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.

[@donbell8187]

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

[@shotsrodder]

Your enthusiasm is contagious 😂😂 nice job Karl 😎

[@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.

[@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!

[@keithmason9342]

Hey Karl, what an amazing build! Your skills never disappoint. In your hands, even the simplest tools become precision instruments. You took junk and built a very useful power hammer. What next? Possibly a silk purse out of a sow's ear. Nothing surprises me at this point. Thanks and we'll see you next time.

[@MakeItKustom]

Hahahahah ! Thanks kieth. It’s a lotta fun

[@scottsprague9974]

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

[@russtuff]

Somehow this channel continues one up itself every week 🤘

[@DustyMacsGarage]

@13:35 this is frikkin 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. 😇

[@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 👊👊👊

[@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.

[@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

[@retroclassicsgarage]

Your gas cutter skills are sick bro!!!

[@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👍

[@jorgecardona4901]

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

[@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”!!

[@steveveness3829]

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

[@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.

[@jimgordon3274]

Thanks!

[@MakeItKustom]

And thank you Jim 😉

[@Enter-a-name55]

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.

[@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 😂😂😂😂

[@billarroo1]

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

[@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

[@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!

[@stumpymeadows5217]

You are so positive. I love it.

[@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.

[@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.

[@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!!

[@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.

[@albertpierce6263]

When I saw the motor I thought you were going to start doing fabric upholstery. That is a 1/2 horse industrial sewing machine motor. I am working on a 48 Chrysler Imperial Royal 3 window and have the need for this machine. Thank you for the inspiration, I will most likely use the lathe and mill, only because it is in my arsenal. But this is great for the garage builds and keeping an art alive that isn't seen much anymore. Great job keep teaching on your channel it's a great thing. How bout that he'.

[@donaldlawton7384]
