EASY Thumbnail SHRINKING Dies - DIY Power Hammer TOOL! Step By Step GRIND WELD POLISH 

Over the past year this has developed into my favourite channel!

Hey Karl, that kink in the hose leading into the air hammer could be limiting your air volume and therefore power.

It's always interesting to see shop made tool videos

The hammer jammer is a awesome name for that tool

When I first started to watch your channel a few years back, I didn't accept that you built a shop on low budget. BUT. Karl thank you for bringing us along. My shop is so improved and so is my work, because it is actually nice to be in the shop😂. Look forward to you 2 vid a week aim, good luck, Joe

The tools are great. With a little bit of time you have shown us you can make tool that most people can't afford to have . Thank you so much.

I love your thought process that it doesn't have to be perfect to work. 99% of the people that will use this machine will do a few projects with it, be really proud of the results, and not use it everyday for the rest of there lives. Thanks again for the content. On a side note a better /expensive air chisel would probably make a big difference, I have cheap ones and one snap-on and there is no comparison to how hard it hits!

My welder is where I first spent my money. The high setting would make that a molten pile, lol. So that I'm good on.

I love the tools. I love the cars too. Just can't lose.

All this needs to make that die work is a decent air hammer instead of that cheap little princess auto unit. I have been following for a while now, made a shrinker yesterday but I used 1/8" bedframe angle, as that is a medium-ish carbon steel. It works, makes smaller tucks but I'm very happy with it. I made the stretcher tool a few weeks ago to fit my "chief" air hammer, very very nice! I want to make a version of this tool soon as well.

Excellent video Karl...its amazing what having some welding skills and a bit of thought can produce...not just in an entrepreneurial sense but also in an educational sense. Never fail to learn something new watching Make It Kustom

Your approach is so neat and demonstrates how great results can be achieved for little money and your own time !

Hey Karl, I had been wondering about the hardness of dies. Glad to hear that cold roll can be used. That really is a handy little machine. I have plenty of 1/4 inch steel, so there may be one in my future. Thanks for sharing with us. Take Care

Fantastic-I thought it might do it for the hobbiest that is an absolute bargain. Karl You are the Man!🎉 As we say in Aus - she's a bloody ripper!

Karl if you think the tool could use a harder hitting air tool, try a needle scaler. I haven’t tried one, a friend bought a planishing hammer that uses a needle scaler and it hits a lot harder that his planishing hammer that has a air hammer. Really enjoy your videos whether it is car or tool content.

The thumbnail die does work in that hammer! thinking maybe a larger version of that hammer would be nice. the versatility of that machine is going to be great...

Hey karl First thanks for the good vidieo. And you maybe take hold of Brent and help him with hes tik welting for as he say him sefl he it strugling with it😊 . Greedings from Denmark

That little tool is awesome! I'm here mostly for the cars, but the metal shaping instructional videos are great too.

You could also use high tensile filler rod and face harden it like you would a excavator or dozer bucket

Love your videos and you're such a cool guy!

oh man, very keen to catch a class here in Australia

Cool video… I am loving your continued effort with the hammer. I like that it’s ability continues to be expanded and deepened. Keep up the great work

Cool, I really like working with the tool

What about welding with hard facing wire or electrodes to create some hardness

Is there nothing you can't do Karl. I'm going to have to make one of these tools myself just think it would be quite expensive to buy the kit and have it sent to me in Ireland. You are a genius Karl and I just love your videos thanks for sharing all this with us.

hey Karl, thanks for all the knowledge you share, I love how you break down your thought process. to give back I got a tip for you, when it comes to hardening steal with water, it's true that it will harden it, but it makes micro cracks thru out the piece. it's best to use oil I've been told to use use motor oil because of the carbon content.

24 seconds in and its already a thumbs up from me.

Hammer down Charlie…. Winning….😎👍 Every time you test these machines you are saving my time. Awesome vid Karl.

Sorry I can’t make it to your show/class. However, I love your RU-vid channel!! ❤ Can’t live without it. Thanks

nice very great job thanks for sharing us

Excellent information and tutorial....

Your air supply hose is kinked at the handle. The dies are designed for a half inch shrunk edge . You can push deeper but the sheet may get overworked and will become brittle. Larger dies with a longer curved lead in to the flat area which you want larger will build more bowl faster. Your machine is a fast swage with so many BPM. It's good though what you called the thumb or thumbnail is actually tiny, you must agree? A few minutes with your head in a die making book will give you the idea better than I will. Also a sharp corner where the die pushes "into" but is not actually pushing on the sheet (the relief) is better allowing the sheetmetal to bunch up in the void on the outside of the curves. Being polished is excellent as the sheet can slip as it must while forming. Thanks for encouraging all those who are keen, to have a crack at it.

With 110v welders, you get more penetration when using flux core. Weld outside or with a good fan because it will be more smoke.

I'll definitely be interested in doing a metal class with you in Perth. Or even better would be at Bennett's Customs in Dunsbrough. Keep us posted with Dates please. Cheers

Thanks for sharing -Spanky was here

18 guage . Definitely a win . Cool little hammer . So simple it could be made to hammer many different ways . Even using just a hammer . Well done .

I look every day for my kit, can’t wait.

You can always case harden dies etc with something like Kasenit.

If you were to grind in bevels on the plates before welding, you would get much deeper penatration. The more solid the anvils, the more work actually goes into the piece being worked. Work energy is being lost in the small gaps. Otherwise, I'm loving the concept of your little machine. Keep the great ideas coming.

Thanks for trying that Karl,they'd be awesome on aluminium .man,what a shine too.cheers,trigger,london

That is a cool tool! Take care

Hammer Jammer or Hammer Mammer are cool names.

Awesome video thanks for sharing

Awesome tool. To harden the dies, you'd likely have to case harden them, as most typical mild steel plate doesn't have enough carbon in it to harden when quenched. Case hardening diffuses extra carbon into the surface, making the outer skin hardenable. An easier method would be to profile them from a steel plate which does have enough carbon in it, but not so much that it is not weldable without cracking. Something like Hardox wear plate (used for excavator buckets, etc) may be a possibility. Also, after heating until cherry red / non magnetic, and quenching, you'd need to temper them too. As quenched, the steel will be too hard and too brittle. Tempering will reduce the hardness / brittleness, with how much depending on the tempering temperature. Another option which may work well is to use a more normal low carbon steel plate, but do all the welding using a hard facing filler rod. These are typically used to build up worn wear parts (such as excavator bucket teeth). The resulting weld fillet is already hard. I imagine it would work well for these dies, as the surface of the higher stressed parts end up effectively being 'made from weld' anyway. Grinding and polishing them to shape would be hard work though. The bigger mass of the tools will be 'absorbing' some of the air chisels energy relative to the profiling tools. The heavier the tooling, the more energy will be used up accelerating and decelerating the tool, leaving less energy to work the sheet metal.

Really interesting watching this tool go from idea to multifunctional shop workhorse! Well done and thanks for taking us along through your thinking and process! Go Japhands, keep moving forward!

I am keen as faaark for a metal shaping class at Bennetts Customs. I am gutted i missed the meet and greet last time you were here. It would be awesome if you did the same thing here where we build that tool on day 1 and day 2 (and hopefully day 3) we do a bunch of metal shaping. Anyway, love the videos and cant wait to see more work on the cars

Love the car videos love the tool videos keep it up!!

Cool tool!

Play with the setting on the air hammer, maybe a different frequency of whack-whack-whack would surprise you, try the whack-whack setting, or just the whack setting!

Yes please do a metal class while your over in Perth, was awesome to meet you last time so would be keen to learn some more from you 🤙

he's a man ahead of his time , like the great mayans

The dies will work harden with time and with rewelding, polishing, etc. a better hammer or a needle gun can be an upgrade for later. But this is great for people starting out to see if it's something they like. Love the content! Looking forward to seeing more on the caddy and all the rest!

💚🇬🇧🌱 Keep it coming Karl👊 great work dude👌

Rather than dunking mild steel in water or oil to try to harden it ( it won't), try case hardening it to add carbon to the outer surface. Lots of inexpensive was to case harden on RU-vid and other media.

Awesome!

Use pickling vinegar to get rid of your mill scale. Let your metal soak in it for 24 hours removes it beautifully.

Awesome stuff Karl. Thanks again for sharing your skills with us.

Gidday Karl , can i suggest putting a spring or two on the swing arm to hold it up so it can hit properly and you don't have a heavy drag as when you were doing the bowl , ? . cheers

One of the drawbacks with using MIG for sheet metal is the weldment is so hard. You can use that hardness to your advantage though while fabricating tooling like these thumbnails.

Notice your air hose is kinked a bit on the little power hammer. Is that possibly 😢restricting the airflow a bit?

Pure genius! Fantastic idea!

Great video as usual. I spend my week waiting for your video’s. Just wondering if you will be offering any local classes for us BC boys.

Hi Karl, loving the power hammer. In regards that you are worried about the impact gun not preforming on 18 gauge sheet you can get more powerful impact gun. What you have is what you looks like a 4x gun. You can get 5x and a 9x guns. Just a note the impact fitting (snaps) change in diameter according to the size of the gun. In the aircraft industry is where you’d probably find bigger impact guns. Hopefully this info might help. Cheers from down under.

Awesome vid bro, 👍

felicitaciones, excelente herramienta

Użyj dwóch sprężyn Jedna na górze druga na dole ✌️

As you make all these fancy dies and tools you need to number and catalog them in your note book with documentation so 50 years from now well you know what i mean

Excellent video thanks Karl.

Awesome ! Mad skills brother. Thanks for sharing ! I definately want the kit.

Hop u open RU-vid channel for that kind of video's we use to see u working in the cars an we enjoy it but now its like diy channel ! Hop u understand my point thx so much

Love the channel and the tools! A question about the profile hammer: what is the purpose of the swing arm that the hammer impacts? Why not have the die mount to the hammer directly? If you find the swing arm cracking, what about making it from DOM tubing and notching to fit the frame and die holder?

I think the top die just needs to be lighter. Maybe just one less plate thickness would do the trick. The weight is eating up all the power of the air hammer. Or just send 200psi through that poor air hammer!

All purpose tool to be sure

You may have to go with a Mac air hammer they are a beast and they have a long shaft I’m gonna buy one of those kit from you I was thinking of building one a few weeks ago but you beat me to it lol … Doug

That is the Hamba Jamba

A little better power hammer mite be the ticket

Damnit Karl! Shut up, and take my money! I was hoping you were going to build these thumbnail dies for the machine I have ordered. I have a small heat treat oven. I'll let you know how it goes.

"Die transfer is real" tshirt 😂

Got a thumbs up from me and only 8 minutes in to the video. 👍

Hammer Jammer is a great name! I vote yes

I keep wondering if striking force is being lost between the many mechanical joints between the hammer and the die. Would it perform better if the die had a bit inserted directly into the hammer. The current striking arm could be designed to function as a guide for the die and also prevent rotation of the die. Another great project and video.

Great little tool I have enjoyed the videos. Will you still offer the files to make the toll as you mentioned in the first video.

Watch that hose. It swells up way to much. Might explode. 🤘🏼try adjusting the air pressure knob on the Gun.

Increase the air pressure????

A longer barrel hammer would give more power

Would you ever plan to hold metal shaping classes at your shop in BC?

👍💪

It's "The Hammer Jammer", man. Don't fight it!

so a little more powerful hammer you think will work better

Do you sell the cad files for your cool power hammer ?

real quick question, are you going to get back to building cars anytime soon. Thanks, enjoyin' the channel

Would using an air hammer that has a longer stroke work? It would be slow....but they hit a bit harder.

Prueba con hammer demolición , electric , mucho pawer

Nice Job! just wanted to ask can you confirm the dates you will be in Perth? did you mean March 24- 25th? will you be back at the Hare and Forbes display? I met you last year in Melbourne, it would be great to catch up again. thanks

Do you offer dxf files for the thumbnail dies?

them things are snow hard

Вы меня заразили, спасибо.

How many people are you limiting the class to?

so do you do classes in any other state other then navada and commiefornia????

👏👍😎🇦🇺🐈‍⬛
