4x4 PTO Driven Timber Trailer BUILD Ep.9 - Tandem Axle Completed
HTML-код
- Опубликовано: 1 окт 2024
- Turning rusty hexagonal steel bar into adapter bolts in the old trusty 1k62 lathe for the BMW E39 differential back plate since I cut off the original diff mounts in a previous episode. Cutting outer threads and drilling the bolts in the lathe but hand threading the inner threads. The original BMW bolts fit the adapters that make it possible to install the diff to a flat axle back plate I cut out on the homemade CNC plasma table (made by me and my friend @blackloopcnc9415 ). At the workshop I'm using FreeCAD drawing software, it is free and easy to use if you've had previous experience in other CAD programs. SheetCAM is my go-to program for converting CAD files into G-code that then gets used to cut out all the parts on the DIY CNC plasma. While making the BMW diff back plate I mess up the hole pattern and revisit the plasma cutter's hand torch and modify the freshly cut plate. The result is as expected - rough and ugly. I'm mocking up the axle so I can take measurements for the side plates for the bearing blocks. I have my reservations when it comes to these bearings - I guess these will be the first parts to fail and have to be replaced with something more reliable in the future. After the side plates are cut and tack welded I'm making a tubular frame from rusty rectangular tubing that gets cut to size on the cold cut circular saw / wet saw. After getting the tube frame done and the front of the diff mounted the axle is ready to slide front to back for load balancing purposes and for reducing tongue weight of the trailer. The tandem axle position will be adjustable with hydraulic cylinder mounted in between the frame rails. But all of that in the future videos. Stay tuned for the next episode & thanks for watching!

You should weld some 1/4" strips around the ends of your sliding tubes to keep them from flaring open easily.
I think your shafts should be riding on TWO bearing on each side. You're putting a lot of weight on the internal bearings of the diff and I'm not sure if it will handle it-- since it's not really made for it to have that much radial leverage against it. Maybe I'm wrong and those bearings inside that diff are quite large.
Can i work with you ??
The idea is good and the embodiment is good, but how many tons of lumber do you want to transport 5 or more at a time?

I think I might have been tempted to have made the axle shaft hole in those bearing mounting plates bigger so if you ever need to get the differential out you'd have the option to pull the chain boxes off, remove the bearings, and get to the grub screws on the axle shaft locking rings. It's always handy to engineer in several ways to dismantle machinery. That way your life doesn't get made annoyingly interesting by one inaccessible rounded off bolt.
I thought the same thing. Looks pretty tight to get to the bolts that attach the outer axles to the axle stubs that go into the diff. You could probably drill an access hole through the side plate to access those bolts - IF you can still rotate the axles to line the bolts up with the holes.
I would have been tempted to delete the bottom of the side flange so you could just drop the whole transmission assembly to work on it away from the trailer

The more this build comes together, the more I realize how awesome this thing will be when its finished.
How heavy...
Молодец

для лохов да )) деды в тайге что-то такое строили из вилиса ) металлы подвели как и этого умельца ))) сыроиятины нарубил ( вася в тайге и вертолёт строили металы не дали летать )))))))
Estou ancioso para ver esse equipamento em funcionamento. Saudações do Brazil.🇧🇷🇧🇷🇧🇷
As heavy duty this whole frame and especially the chain housings are, I fear the differential will be a weak point in this axle. The housing of the diffential was never designed to deal with any outside loads and now it looks like you're going to use it like a solid axle, I'm not sure it will hold.
Theses bmw differentials can take a lot of abuse, but yeah I think the bearings will worn out fast

I agree, now the differential have to handle all the weight. But let's see!
The load on the trailer will be transmitted to the ground via the tires which in turn will create a moment arm quite substantial due to the leverage and the opposing moment arm is going to originate in the bearings of that differential. Every differential I’ve ever seen has one function and that’s to impart rotational movement; never to to take those kinds of loads…..
Thats what I said last video
However it is a small trailer getting pulled my a utv that's really just for fire wood
It's not going to see 1000miles of highway use every week
Itll certainly wear out but how far into its life is to be seen
It think the cir clips holding the axles it are just going to pull out as soon as he makes a sharp turn loaded
Anyone that's changed a cv knows those circlips arnt structural, you can just get a medium pry bar in there and pop the axles out without any trouble
If I may add one improvement from walking beam axle experience
Weld some chains or some sort of stop to limit the travel of the chain cases
As it stands there's nothing stopping the cases spinning a full 360 around the diff
Not usually a problem but when you get into soft ground or even get bogged the front wheel can get pushed down and as you drive forward it simply rotates down rather than lift up
It can be a real pain to get the front wheel to come up rather than end up going right under and becoming the back wheel
Been there before when trying to pull a trailer and i ended up with the front tyre completely under ground and the back tyre up in the air
Of course If you reverse the same thing happens just backwards
You can tack weld one of the round cut out blanks (8:32) from your plasma table over your access hole (8:48). Than use the plasma cutter by hand using the blank as a guide to keep the hole nice and round.
Then hole will be half the plasma torch tip bigger radius than the blank, that is diameter will increase by width of cutting tip because using blank as a guide is guide line and not the cutting line
Box rotation must be limited, with chains in example. If wheel gets stuck on both sides all the torque will chose chain box to rotate, it can push stuck wheel into more stuck state. I can't fully imagine this kinematics, but limits are required and chains can be simply bolted and adjusted on the go, as needed

The gears inside the diff cause very large radial and axial loads that the bearings inside the diff have to handle.
@@celeron55 Yeah.. but now you have all of those forces PLUS the entire weight of a fully loaded down trailer slamming over rocks and logs, and also pressing down on that shaft and putting all that weight on those bearings, even when it's just parked and not moving. Maybe it's fine, but I would have put a second bearing on the inside of those shafts.
Wondering same thing
Bearings could also be added at the outside of the chain housings.
I can see that the second bearing got to be supported also to create an axel if not all the forces will be between this green on and the one in differential this is a bmw diff at normal operating nothing is hanging on it I don't know how it react when you aplly forces on housing. Supporting the outside bearing will fix everything unless you thought about it earlier and I'm just panicking. I thing that's impressive build I'm excited to see the progres
He need a second pair of big bearings
@@NaturalBBler he already has a two bearings per side so it's OK. It's just a matter of connection the outside bearing to frame somehow like it's done on horizontal mill

we do similar setup in race car suspension when going from a 4 link to a 3 link.
we just sandwich the plate between the differential and the cover. giving us something to weld on
Espectacular
Man, this FreeCAD seems to be such a great tool! I think I'm going to start practicing with it.
The cuts coming off that table are pretty clean! Wow.!!! That’s sweet!! Must be a powerful plasma cutter setup
it's looking great, can't wait to see it in used.
This is going to be impressive when finished.
I still think that Mr. Chop should have red coolant and say "Yum Yum,"
Tjrs un plaisir de vous suivre ❤️🙏💪👍🙏🙏🙏
I'm so hooked on this build can't wait to see it finished awesome workmanship thanks for bringing us along
Impresionante como siempre doonday waoo que exelente proyecto en verdad eres el mejor salu2 desde Puerto Rico
Инструмент у тебя хороший
Kỷ thuật công nghệ cao để sản xuất ra một ý tưởng mới 👍
I’m sure you’re already 8 steps ahead but that differential looks like it might be trapped in there.
I’m probably missing the one obvious point but it certainly doesn’t seem easy to access the axle flange bolts to separate the stub axles and drop the differential.
I look forward to seeing the answer to my concerns.
I really enjoy your projects and I'm hoping with the amount of followers you have, you can build a building to store your steel in. It's sad to see it stored out in the rain and snow.
Nice work 👍.
If I had your skills bud I'd piss on mine and walk away. Awesome to watch all of your builds
Excellent work 👍👍👍 . Thank you for sharing. Be safe 🇨🇦
Nereli olduğumuzu bilmiyorum ama iyi bir tornacı ve ustasınız ben tornacıyım iyi çalışmalar
I have been following this build and have enjoyed it. I don't mean to be critical but you need to clean up your lathe. I have been a machinist for over 30 years and was taught early on to keep a clean work space and machine. And no your work is not ugly. In my opinion it is exceptional. I have seen a LOT of fabrication in my 36 year career and your's in top notch...
Donn, All of your previous builds were next Level... This Build is Insanity !!! Your a Master to the power of 10.. Good Stuff !!!
loving the progress you're making. 👍
Мне о таком только мечтать только приходится
I can weld My Dad is an old school tool and die guy but I’m lost when it comes to solid works and things I taught myself cad for construction but this stuff is way above my pay grade!,
Awesome skills dude. Kudos!!
Perfection. Hey when I was a Fitter/Machinist, Toolmaker, Welder & many others, when I was trying to spot holes to cut I was taught long ago that if you mount a bent piece of cardboard into a V as you are fitting a backing plate to it you put a dab of thick paint on the tip of the V so that when put the plate up against the irregular sized object it will mark where you need to cut out with your magdrill or holesaw. You could have done that with all of the bolt holes & the PTO hole. CAD with paint, Cardboard Aided Drawing with paint. Keep that in mind for future use.
It's coming along great Donn. It's going to be awesome when you get it finished. Looking forward to your next video, always enjoy watching what's next. Stay safe and keep up the great work. Fred.
I'm jealous Donn this is the best machine ever in my book. Appreciate all the work and time you do to share the craftsmanship.
Looks great! However, should you need to take the diff out, how are you planning to be able to do that?
I was trying to determine that as well.
Looks to me It'll drop straight out bottom once unbolted. The axle shafts have flanges on them that unbolt in previous video that he made.
When that diff breaks you will have lovely time with it
Can't wait to see it all working 🙌 👍🏻👍🏻👍🏻👍🏻👍🏻
O motor e potente o suficiente pra suprir várias rodas ao mesmo tempo
You might consider; Drain plugs on the drive boxes for moisture and solvent drainage after chain maintenance. also flooding the boxes with Co2 would reduce corrosion. I understand they're not air tight.
just a thought when you move the trailer axle unit .. UTV might have to be in neutral so that the axle will slide and the wheels will turn ?? great build so far .. keep up the great work ..
I'm sorry but nothing about your work is "ugly". The "ugly" plate, with its offset holes, was about as good as most of us can do. Along with the UTV this is a brilliant design. Congratulations!
Thank you for the video
Love your work looking very nice
The pivoting between the tires halves the effective size of the bumps but without springs the frame is still going to take a beating.
Nice to know "thingamabob" is a world wide term! 😎
Thingamajig n thingamabob are defo world used🤣
That is going to be one sick trailer, love it...
Just a suggestion, if you have a scribe feature on the plasma, scribe your difficult pieces where you can check your dimensions.
Good jop! 💪
That is awesome trailer, movable axle is really great idea 😎
Can't wait finish..........................
That thing is going to weigh more than my truck.
Terrific project! Great entertainment.
I wish I had a farm so I could build nice useful things like Donn does :) Keep up the good work and ur welds are greatly improving since my last comment....
I'm calling the trailer the "Trunionator". I love it!
Great work Donn. Can't imagine having to do all this without the CNC Plasma. Could be done but what a PITA. Thanks very much for sharing.
Радует
Когда уже в лес поедем на этой чудо технике?
Couldn't you use a solid axle for your walking beam instead. I think it would be a fair amount stronger. You just need to find an axle with the same gear ratio as the BMW IRS differentials.
love this build
А по-русски умеешь разговаривать
Outstanding! I love every one of these videos and all of the Patreon content, too. Keep up the great work!
I’m amazed at all the thought you have to put into this thinking three steps ahead sometimes it’s two steps forward and one step back but it’s turning out to be very amazing
Maybe you can use Anti Friction coating for the sliding axle mounting rails. Molykote or something else.
We use it on aircraft landing gears.
You can buy it in spray cans.
Probably not needed, the problem is that the wheels of the trailer and the UTV are directly conected, when he want to adjust the tounge weight the wheels need to be indipendet, means he need some sort of clutch or disconect the driveshaft.
He probably does neither of that and just uses pure force to push the trailer axle back, would probably work well when he drives slowly while doing so.
Than he needs a pretty strong hydraulic zylinder anyway, grease is not important for that, he will most likly only adjust it a few time per year wear isnt a problem.
@@jonasstahl9826 I think he will use a telescopic driveshaft.
It looks to me like a driveshaft between a tractor and a farming machine.
They are telescopic.
I’m curious,is there going to be enough clearance for you to get that trailer out of the barn with the log loader on it?
I can already imagine a whole video "4x4 PTO Driven Timber Trailer BUILD Ep.XX - Demolishing barn to get the trailer out"
Donn, the amount of work you do cleaning surface rust off box section, chanel and plate, eg @11:40 especially from your used/stock pile, it would be worth the effort to set up an angle grinder with adjustable guides/rollers/bearings and a long angled broomstick style handle to enable you to do the entire length in one clean sweep using wire brush head or head of your choice . Minimal effort to set up, frame attaches to 3 handle positions on grinder head, and would save you hugely in time and effort, cheers
Keep up the good work
สุดยอดอีกเเล้ว เครื่องมือตัดเหล็กราคาเท่าไหร่ครับ
The moving axle should have a wear plate on underside then you won't wear down the box section wall on the slider just replace the wear plate👍
Travaille très impressionnant
You are so talented in the angle grinder, we love to see you use it and create things from nothing. You make it look so easy! Great project!

I would suggest using a dry graphite paint my favorite here where I am in Texas is EZ-SLIDE I use it so I don't have dirt sticking to the parts I'm trying to keep free mostly i use it on my fithwheel hitch and on my ratcheting chain binders
Hope this helps
Hey Donn, looking great, can't wait to see it in action. Stay safe.
You need to have a contest for how much the total weight will be.
Feck'n heavy!
Great job, but weight don't be a problem? I know it have power wheels but still it isn't going to sink in a mud, specially loaded with wet wood? it's only peugeot partner engine and it's gonna lose some efficiency over the transmison shafts, diferencials, chains etc.?
Привет👍👍👍
, я себе такой же сделаю. Ток не ведущий 😁😁😁
Looks good man, getting very interesting :-)
So in other words your halfway done, dont get anxious bigger mistakes will happen beside a couple holes off location.....
Sistema de tração tipo bumerangue fabricado pela ENGESA do Brasil nos anos de 1980.
Looking pretty bada$$. Can't wait to see it in operation. You are one heck of a fabricator.
Not saying it won't work, but I think the way you've set this up the differential will be subject to quite high bending moments that the case and bearings wasn't designed for. I'd be a little worried for the longevity of the diff?
All I want to know is how the box section you used to trim the edge ended up with a round pipe shaped end....... 🤔🤔
I thought the exact same thing. Looks like an old wheelbarrow handle.
I love your use of the English language. "Thingabob" 😂🤣, and "Play ball!"
Donna your one of the best engineers in ever seen, keep it up.
amazing and brutal job Bro!!! congrats!!!
Bro gud job .
FM Donny you building this to last hey! Wow as usual beautiful engineering
Thank you for sharing this video, you do a really nice job fabricating. I don't know what language you speak but if you do speak English I would really like to hear you talk about what your building and while you're doing it it would make the video much more interesting. Please understand, this is not to say that it is not interesting as it is. If you are not English-speaking then turn on the translation Matrix. This would (to me) make your project more interesting and I suspect to yourself as well. From what I have seen on the many RUclips videos that I've watched if you just talk to the camera like it's a person that's sitting in the room with you and you're explaining to them what you are doing really works well, it would greatly enhance this very well made video. This comment is only a suggestion, please do not be offended. Thanks, Bob, Virginia USA
