- In this video I show you the construction of a motorcycle frame, the original was so badly damaged that this had to be completely rebuilt.
Also in this video I use mainly standard tools that should be found in most metal workshops.
The frame is built from chromo steel ( 25CrMo4 )
This is not a complete motorcycle project, but I show you the interesting fabrication steps.
Have fun watching.

No crappy music, No annoying banter, just absolute artistry
The square tube collet is so simple yet so effective, I am in awe of your craftsmanship!
Sorry I just cannot find any possible way to praise the work like this. So I simply liked and left a meaningless comment here to show my respect.
Exactly!
Thanks
This guy is probably a surgeon making frames in his spare time :-D
👍
well said
No. It's Boris Becker moonlighting.
Damn, you're good. But you already know that. Thank you for sharing your genius. I'm a retired aero engineer, and I learned new things here.
Thank you, I am glad to hear that my videos are also educational.
Thanks for watching
10:19 😅 I know that feeling. Fantastic work BTW 👏 👍 👌
Shear precision, craftsmanship at it’s finest. Thanks.
Aerospace level precision. It was so satisfying to see the way the pieces fit together.
Thanks
Having that spindle n chuck on the indexing table makes it popular as a go to!
Nice workmanship with the tube notching, makes a big difference in the build quality. This man is a patient and thorough skilled tradesman.
this design is absolutely beautiful, your compound angle tube notching skills are unparalleled!
Never get tired of watching the videos, your craftmenship and engineering sense, never cease to amaze me.
Every cut fits so perfect that tacking is super easy and smooth.my respect
I've watched several builders make frames for motorcycles but never like this one. Awesome job 👍
Thank you
Been working on a design for a bike for awhile now but didn't know how I would tackle the frame.... this is super helpful. Excellent video!
This video is helping me on my way to build a fully custom bike just gathering knowledge at the moment and this helped a lot
Your precision is truly outstanding. I use your videos to relieve stress. Amazing work, a true master.
I just came across this site and immediately subscribed. Combined with the 46works channel you get a complete view of the art of motorcycle design and construction. Excellent stuff!
There's not much that's more satisfying than a really precise tubing fit up
Ok you've taken what used to be simple cut and weld to fit and turned it into precision craftsmanship. Im not sure its a good thing, but your definitely an artist.
Just look at the welds on the jig even... I was laughing to myself because I was thinking this fits that stereotype of German engineering precision then looked up the channel information. Well surprise surprise. haha. You do beautiful work. It's always a joy being able to watch a true craftsman.
Eine wunderschöne Arbeit und wirklich interessante Detailarbeiten. Sehr angenehmes Video, solch kunstvoller Arbeit zuschauen zu dürfen entspannt und beruhigt. Ich freue mich schon auf Part 2.
Danke dir.
An absolute pleasure to watch a master craftsman , finally someone who works to zero tolerance 👏🙌👌👍
Thank you for watching
@@KRTframework what is the size of the tubes ? And thickness
This is not just metal fabrication anymore, this is fucking art! This is no doubt my new favorite fab channel on YT (and I follow a couple lol).
Thank you very much ;)
Just beautiful to watch someone that is so good at what they do! Mesmerising!
This video is oddly satisfying and oddly kinda creepy at the same time. Love the craftsmanship and machine work is incredible.
Thanks
This is fast becoming one of my favourite channels, pure class , love it🙂

Thank you
The jig in its own right is a masterpiece!! Amazing work
Thank you
No words found to praise his skills... Love from the State of Tamil Nadu, Indian Union.
Thanks
Ein Künstler der seine Kunst beherrscht, große Achtung ⚠️
You have a gift sir! A great workshop too, but your gift is greater! You have my admiration.
Thank you very much
Lovely to watch mate, looking forward to this series 👍🏻🇦🇺
WoW. What a fantastic workshop being controlled by a Master Craftsman. I'm subscribing so I can watch more of your fantastic skills!
Thank you for watching
I love the fact that you are meticulous about deburring even the edges that will never be seen. Excellent craftsmanship.
I See the edges, but it is better for welding ;)
@@KRTframework I've worked with welders that won't deburr the inside of the tubing. Won't clean off the table. Drives me crazy.
Yes
There's artistry, and then there's this guy. TIG welding: the gentleman's approach to welding....
Clean, Lean and Elegant. Pleasure to see this kind of work.
I long waited for a quality production in both film and build. Here it is.
Keep it up sirs!
Thanks
Supreme craftsmanship. Looking forward to more 👍
Was ich absolut klasse finde, ist die Tatsache, dass Deine Rahmenlehre handwerklich um Längen besser ist, als das, was manch Andere als fertige Arbeit abgeben...👍
Der Sinn ist klar, schlecht positioniert bedeutet beschissen geschweisst.
Aber selbst da sitzt jede Naht wie gemalt. Respekt!
Gerade bei sowas finde ich, kann man üben um sich stetig zu verbessern, Klar könnte man die Rahmenlehre auch mit MAG schweißen, aber das macht mir zum einen in der Werkstatt zuviel Dreck, und ich bekomme so wieder etwas mehr Übung beim WIG Schweißen dickerer Sachen.
Lovely to watch mate, looking forward to
Absolute stunning and clean work! Curious on the end result and the bike fully build!
Keep on going love your videos
That’s ART really awesome 👏 and waiting for next parts .amazing workpiece 👍
I want your machine shop. It seems like heaven.
First i found born co chanel they were awesome than i came across 46 works he is genius but this guy is master
15:48 as if the video was not awesome already, he comes out with a height Gage he got from King Kong 🤣 I've been fabricating for 35+ years and this is some aerospace stuff going on right here, nice work my man 👍 liked and sub`d
Not only the skill to do such work but the tools....man you must be very proud of your shop. I feel the machines you have to do this type of work are just as impressive...your knowledge to use them to execute your designs....outstanding
Yeah. Top quality stuff. Production tube bender? Wow
Thank you very much, it also took some time to learn it and get the machines
An excellent specialist for a top quality work. Not sure however than a similar frame in carbon fiber would cost more with a good gain in weight and rigidity.
excellent craftsmanship
5:36 that bending mechanism is freaking creative
Very nice full with art,precise, patients remind me with my uncle hobby.👍👍👍
😱😱😱, such precision, true craftsmanship, much respect, you earn yourself a subscriber, 👏👏👏
Thank you
Such skilled craftsmanship wow
Excellent work, very interesting use of the fly cutter to get the angle against the neck tube!
unfortunately i didn't have a cutter with the right diameter, but if need be i can use a flycutter, not so nice, but it works
@@KRTframework Oh I wasn't criticising at all, I thought it was an interesting solution and it worked nicely
Absolute class craftsmanship
this type of motorcycle frame its 1980, looking EGLI,MOKO,RAU,i drive this bike many years and its beautiful,greatings from a swissbiker
Thank you, yes the frame is built after Egli model, because I have a destroyed frame here.
Greetings from Germany
I'm just about to start a bicycle aluminum frame. I read is okay to tack the frame on a jig but is not a good idea to weld it on the jig to allow expansion and contraction. Any advice please.
Präzise Arbeit, freu mich auf den 2.Teil
great job it's a pleasure to see your work
Awesome Video! This goes to show that you do not need a bunch of voiceover or music throughout a video to make it thoroughly entertaining. One question though, What is the point in drilling the holes where the tubes meet the main backbone and head tube?
I drill the holes so that I can get shielding gas into the frame during welding. you can also see this in the Part. 2, which is now online.
i wanna leave where i live and come work and learn what u r doing here sir...... seriously i wanna learn how to build bikes sooooooo bad. thanks for the education.
Can I ask what the frame was going to house and are there any pictures of the complete bike? Fantastic work
Sehr schöne Arbeit, ein Genuss zuzuschauen.
Danke sehr
That was fun to watch, I’d guess it was even more fun to do! Subscribed looking forward to the rest of the series.
Cheers
Thank you
Perfect work, colleague!
Lovely work. Do you make a new frame fixture for each frame you build? I notice this one has a fixed headstock angle...
You are an Artisan, your work is supreme and beautiful to watch your art take shape. Stunning work you are doing. Thanks for sharing your incredible skill and talent.
Thank you
Thanks for sharing love your videos and your craftsmanship and the simplicity of your frame jig impressive
Thanks
Damn dude, you’re not Fing around as they say.
Cool 😎
10:20 nothing more frustrating than getting something in position, just to realize you’ve left your marker behind
5 times a day, minimum 😂
@@KRTframework any advice for a newbie that wants to learn how to build his own motorcycle frame i follow you 💯 from 🇨🇦 #YSW
Sir, hat's off to your skills 🎩🙅♂️
That is a thing of total beauty ,,,
what sort of tube is it , it seems to cut well.
Its 25CrMo4
Parabéns pela execução do projeto e parabéns pela oficina, invejável.
Im assuming that’s ChroMoly tubing by the way it appears ( I know I’m watching from my phone) to be tough to cut with machine tooling, strong rigid and durable.
Our guy is surgical with that holesaw.
It’s like watching a pastry chef build and decorate a cake, without running to the pantry!
всё супер, ровно, правильно, точно, красиво и впечатляет, только два вопроса, рама из нержавеющей стали? используете много инструмента, но не используете лазер или плазму для деталей из листового металла, почему?
Excellent work. Keep it up.
Brilliant fabrication
Buen Trabajo !!!!!!! Saludos desde Argentina 🇦🇷
Danke dir.
Un vero carpentiere al lavoro,ottimo.
BEAUTIFUL WORK
is it cold rolled steel or hot rolled steel used in making frame?
watching this I feel I am obliged to say something. but all in my head is just WOW!
I hope the final result, shines...as the preparation has...👍👍
How do you work out those bevels for those tricky angle cuts with the hole cutters and endmills, is it by eye/feel or is there some secret metalworkers math course i need to discover and learn?
Can you show us how you made the jig would absolutely love it great work
Unfortunately, I have not made a video of how I built the welding jig, but I'm building a Ducati, which gets its own frame, swingarm, etc.. Since I filmed how I built the welding jig.
@@KRTframework awesome are you uploading soon?
It will take some time as I just finished the welding jig and am now starting the project. I think the first videos will come in 4-6 weeks.
Глаз радуется.. Мастер.
You are one very talented young man.
Thanks
Superbly done...thank you very much for sharing
love the bg music? may i know the link? Hats off your skills are sick
What was behind the choice of TIG welding over bronze fillet joints?
Красота в мелочах!
Insane work! Keep it coming!
I love your work buddy.
i'm new subscribe for your channel, i'm from Indonesia
Wish you would talk some about material, material size and what your doing.
Extremely satisfying 👌🏼
Herrlich. Ich freue mich immer, wenn du ein neues Video postest. Danke 🙏
Ich Danke fürs zuschauen :)
What kind of metal is all of the tubing?
Where did you get that steering head tube blank from?
Ça ressemble à un cadre de moto Martin 👍
La poutre aussi est en 24cd4s? Je ne savais pas que ce tube existait en si gros diamètre.
Beau travail 👍
yes, the top tube was not easy to get.
the frame is an Egli replica, ( have one here that is unfortunately destroyed )
Woow amazing thank you for sharing
