Minibike BUILD Ep.2 - Frame Fabrication

Fat tire minibike build from scratch. In this video: minibike tube frame bending and fabrication. This TB-1000 tube bender has proven itself as a great helper. Before having this I was constricted to using already existing bent tubes but now I have a complete creative freedom when it comes to tube frame fabrication. With this minibike tube frame I've gotten some practice in and feel quite comfortable with bending tubes. This series will follow. I hope you enjoy!

whats the tire size ? and brand ?

[@DonnDIY]

22x11-8" ATV trailer wheels. Don't recall the brand at the moment.

[@michaelakins6369]

I'm just a paralyzed guy from Southwest Arkansas in the town of 1300 people and let me tell you how awesome it would be if you did a build on a off-road wheelchair. That would be so awesome! And I feel like it would get you a lot of views

Way cool, Donn. One of your best . . . Mr Chop✓ Tube bender✓ CRC cutter✓ and that rounding bit✓ . . . way, way cool.

[@DanKoning777]

During the bandsaw build [approx 5yrs ago] is when I first thought "Donn isn't your average DIYer." Fact is, he's of the same caliber or exceeds many who do this for a living. You've come a *loong way* in 5yrs-looking forward to the next 5. *Question:* it's clear the engine is set to the left [24:42]-is this to facilitate a ''jack shaft?'' God bless.

[@DonnDIY]

🙏🙏🙏

[@Mikefestiva]

It’s coming along nicely Donn! Fantastic skills 😊 There’s something really fun about mini bikes, they have a way of bringing you back to being a kid, the simplicity of an engine and two wheels 😊👍

[@DonnDIY]

Cheers, Mike! I've watched your video where you and your brother buy and ride minibikes several times now. I hope to do the same with my brother but on homemade minibikes. I'm planning to build three of these fat tire bikes (two of them off the air) so our father can also join us.😄 We're all small kids in our hearts.

[@Mikefestiva]

@@DonnDIY Right on! You guys are going to have a blast (Fun Times) on those mini bikes 😊👍

[@kenwood8665]

Your fabrication skills are off the chart.

[@nathanscott7910]

It'll be interesting to see how you address the gas tank fill cap issue. Unless you just let it go like it is. However, it looked from the video like it would be a pain to fill with gas.

[@DonnDIY]

No worries there's plenty of room to fill it using a proper nozzle.👍

[@CamberKitesurfing]

major workshop envy, that man cave is stacked out with all the awesome tools! If anyone needs lazer cut wheel hubs, engine mount plates and general weld on tabs etc we got a load produced that could make your fat bike build more acheivable if you don't have access to lazer cutters and mills etc.

[@olddawgdreaming5715]

Moving right along on the FAT TIRE MINI BIKE build. Looking great !! Thanks for sharing Donn. Lil Man will enjoy that rig around there. Stay safe, Fred.

[@DonnDIY]

A bit too big rig for the little fella still. So I'm gonna use it until he's of age.🤣

[@Crewsy]

@8:40 I think that’s the step many people forget when they’re trying to bend parallel bends. I’ve seen many put the angle finder on the pipe but not confirm the level of the bender. 👍🏻👍🏻👍🏻

[@coburnlowman]

This is one awesome build. Like your attention to detail is amazing. I'm just wandering why you didn't add any suspension, like a rear swingarm? As a kid I've ridden the fat tire bikes. They'll go about anywhere , but really bouncy. Back then it didn't bother me , but now older , and several back surgeries it would be Ruff , Ruff. But given a chance to have this bike I sure wouldn't complain. I grew up around a small engine shop. Dad also had a fab shop. I , a long with neighborhood kids built "deathtrap" bikes from scrap. At that time none of us had the skill level you have. What we put together, we would work on for a couple days to ride until something broke , and then weld more crap on to it. Finally, they looked like Mad Max vehicles 😂. But it kept us from listening to jazz music , and turning into Riff Raff 😁😂😆🤣

[@DonnDIY]

I've always wondered about tires only no suspension type minibikes, now I'm trying one out myself. After building it.👍

[@ohcrapwhatsnext]

Better be only one, cus you can't compete with Chyna. lol Your so creative that i see 2mil subs by next year...Brilliant.

[@enzobrambilla3692]

[@dakotamax2]

You always have something interesting on the bench. Thanks for keeping us entertained! Love to see a follow-up video of your past projects and how they are holding up. That ATV build is definitely one for the highlight reel!

[@valdis7663]

What an interesting project you started, now I will look forward to the continuation of the construction of a cool swamp motorcycle.

[@matthewmoilanen787]

That bender sounds like I do when I wake up. Anyway, very nicely thought out and the use of your simple jig has made your assembly work come out awesome! Excellent craftsmanship as usual Donn and I look forward to seeing this project completed and ripping around the yard!!!

[@DonnDIY]

Yup, I sound like that too😛

Какой интересный проект ты начал, теперь буду с нетерпением ждать продолжение постройки крутого болотного мотоцикла.

[@Pats-Shed]

Great job so far , you never fail to amaze me with your skill and ingenuity. I particularly love the use of the mill to create the "birds mouth" on the tubes with the correct angle , orientation and distance relative to each other 👏👍. Bravo , keep up the good work.

[@DonnDIY]

Using a mill is a bit of an overkill though. A simple notcher would do the job.👍

[@BarnStangz]

This thing is looking awesome! I can't wait to watch you rip this thing! And man, that jig is so nice, you might as well go into business building these things! Donn-DIY Monster Mini Bike!

[@DonnDIY]

Monster Mini sounds great 👍😄

[@AW-Services]

Wow, Donn. What an impressive build. I would have never guessed that the steel frame was actually a very intricate fixture jig. Great video, and keep up the great work

[@mr.ilshat670]

Круто, 2 часть прибыла.

[@DonnDIY]

👍

[@daos3300]

nice build - can see a couple of issues though (all of which i'll be happy to be wrong about): - the head tube bearings won't last long, standard roller bearings are not designed for axial loads. - suspect your triple trees will bend although those tyres may compensate. - the lack of a frame member between engine/rear wheel is also a weak point. the tubes are beefy but the frame may flex - could be a benefit depending on how much.

[@nommy8599]

I noticed the 1st 2 things too - was looking before asking about bearings. Maybe he could use a thrust bearing instead or as well (planned?) or add some metal to take axial (upwards) load (metal on metal)? I thought the tires might be used quite flat to serve as suspension and keep that front plate from bending at the 1st good bump but they don't look it now. Probably easy enough to reinforce the plate. Cool build though. Perhaps in soft ground it's fine too.

[@daos3300]

@@nommy8599 easiest would be to replace them with tapered roller bearings, would need some re-working to get them to fit.

Definently not right bearings for front fork, but you know that. Could improve this adding right lenght spacer betveen upper and lower bearing inner race. Piece of tube or something.

[@DonnDIY]

Yup, those linear ball bearingsin the steering column are for mockup👍 The tube between the bearing inner races is already there.👍

[@jameslyons1978]

[@DonnDIY]

🤣

[@barthanes1]

Nice head-tube jig design. You set it up with it resting against the frame jig so you could just drop it down and everything would be in place when you were done with it. It was not obvious what you were doing when you started.

[@samasama5]

Nice build 👍 I have dreamed something similar. Same tires 125cc atv engine 3+R semiautomatic gearbox. Long gargo basket in the rear and option for track and ski for winter.

[@paulmartin3340]

Great work as always Donn. Attention to detail is always on point. Just a question? At 22.11 the door behind you opened !!! A cat? A draft ? Or something else???? Whoooo !!! Cheers from Sydney Australia.

[@DonnDIY]

Good question eagle eye! The door comes open when there's wind from east and someone comes in from the front door (grandfather goes for a smoke etc). Since my workshop doors are held closed by friction - rubber hose screwed in since there was no door latches for a thick door as this is - sometimes the air pressure from the corridor pushes the door open. Especially when it's cold and dry air like right now and the door shrinks as well. I hope that answers your question.😛

[@caseybinion806]

Looking good bud

[@franksmodels29]

Looking good great build 👍🏻👍🏻👍🏻

[@tacticalrabbit308]

Donn , I would use a solid bar in the front with bolts that screw in to the ends of the bar and the hub mounted on bearings on that bar , you can either have a flange on one side or nuts on both sides just a suggestion.

[@DonnDIY]

Good thinking👍

[@mrMacGoover]

Those look like the same tires off a Honda Big Red three wheeler. That bike will be idea in the snow.

[@DonnDIY]

These are probably the chinese knockoffs. Those are sold as TV trailer tires 22x11-8"

[@saidbachar2246]

Creative as usual

[@theantichrist4267]

And just think if we only gad a personal shop area with $ 10,00O in used equipment laying around . And enough disposable money ,so we could buy metal ,and all the other stuff to finish off the build process like this . Then we could build stuff 👍

[@itarry4]

How long I wonder before you get annoyed with the lack of power of that engine and we watch you doing a motor swap? 😅 Mate your work is always quality and it's brilliant both watching as you completely tear down and restore old things that's need some love and attention as well as watching you build stuff from scratch you've designed yourself to help you with something that you need to do or do often. I just really wish you'd take as good care of your big tools and machines like your lathe, mill, etc. Especially the lathe really really needs a good clean and possibly a bit of restoration it'd then be a good idea to get some covers for the ways, like on your mill, to ensure they don't get scratched up or damaged beyond what's useful. Probably make a really interesting video or 3 for you to film as, well. Keep up the great work and content thx.

Hey Donn, at one point it sounded like Mr. Chop had dull teeth. Is there anyone relatively close by who can sharpen that size blade? Oh, something else. Lathing thin wall bores, setting the tool rake negative can help on the chatter.
