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.
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
Donn I Love your C&C Plasma Torch. And your Welding is Awesome. Something that I have never gotten a chance to Learn or Do. Not counting your Metal Lathe. And your one Hell of a Fabricator. And what You do for what You have is Amazing.
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!!
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

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.
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
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.
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.
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.
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
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 like how you think out side the box dude, I'm building a trailer that's triple axelbut one axek will be on a hydraulic cylinder if needed. I'm also making a hydraulicly operated gantry crane to lift logs on to it or whatever.it's basically a dumping car trailer with a gantry on it.i designed a steel box which can also be hoisted on to the trailer by means of the arms as well and locked in place to act as a hauler dumper for garbagefrom my demolition jobs or just for hauling what ever. I like the Bmw drive system you designed . Keep up the genious Don! Peace and freedom to you and yours brother!
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
@@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
This dude can build a space ship from scratch and yet people commenting he should do this and should do that lolz I like the fact he doesn't even respond to any if it breaks he's the one to fix it simple pimple

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...
Truly a work of art! Excellent design and fabrication!! Your workmanship and methods are very good - clearly you were trained well and then you have added to that with years of practice and thinking!! Liked !! Subbed long ago!
To reduce work in making the second chain box if it's not already cut in individual pieces, cut as one or more long pieces with cut lines to bend at, as you have done on bracketry in the past. This would simplify construction significantly, you already have a sheet metal bender you made a few years ago, and while not intended for plate, the actual effort to bend the almost fully cut plate is not great. Great work as always Love the commonsense approach with eg using the diff head attachment points for mounting the diff to your mounting plate.
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
Love the idea. The end support bearings are still going to put a load on the diff it wasn’t designed for, it’s going to grenade. You’d be better off with a solid axle and narrowing it, also rather than tight telescopic square outer use rectangle with delrin plastic on the bottom side which pretty much eliminates need for grease although a skim coat on the plastic works even better. I slide 15 ton machines around on old poly water tanks I cut into sheets.
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
Looks like things are coming along. You may want to put a washer or two in place on that front diff mount so there is a gap later on, with such a tight fit later on when you break it down and weld then paint everything you will have a tough time getting the differential back into place. Anyway things take time to get done for sure. Currently replacing a roof on a house pretty much by myself and trying to find days that are decent to work has been a pain this year though I have one side almost completed. At the same time I am insulating the house, running electrical since the old system still had knob and tube wiring, installing datacomm, among other things while also living in the house. Sometimes it's a slow process but if you have to deal with something you do it a little at a time.

You should weld some 1/4" strips around the ends of your sliding tubes to keep them from flaring open easily.

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?

The pivoting between the tires halves the effective size of the bumps but without springs the frame is still going to take a beating.

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
That is awesome trailer, movable axle is really great idea 😎
