I know your idea will work, but I'd like to point out that you have basically created a cam or screw inside the tube. The torque on the axle is now being directed outward along the axis of the axle, pushing out towards your wheel on one side and drive on the other. If the centre weld fails from torque, and the sleeve walls hold, the axle will try to grow longer. The best way with a solid axle is to bevel both sides down to a point, or almost, and then make several passes to fill the void. Then sleeve if necessary / desired. If you have a hollow shaft, bevel as much as you can, sleeve it on the inside and outside. All of that being said... you don't always need the best solution, and this idea will work fine in many applications.
@@DegenerateFabricators Yes, the welds should stop that 👍 My point was that when you cut an angle on the end of the axle it is a compromise. You are gaining a mechanical lock based on the geometry, but you also creating a cam, screw or helix effect that otherwise would not exist. You need to be aware of these forces when you do your welding as this screw effect can greatly multiply the load on the delded area.
@@JoelArseneaultCZcams it also would take massive amounts of torque to screw them apart in that manner your more likely to break the cv in another part
I'm not sure why more people haven't taken an interest in leaving a comment but bloody hell that is seriously ingenious man I'm impressed with that for an emergency something out the bush whatever that is just brilliant

Thanks for the Information... I just took my Solid Half Shafts to the Pro Guy... To be Shortened... He Resptfully declined to take on the Job. So it On Me
I am installing a 170,0 cm wide Tesla rear drive unit in place of a 151,4 cm wide 1978 Rolls Royce Silver Shadow II rear axle. So I have to shorten the drive axles 9,3 cm. Maybe a bit less to make the wheels fill the opening a bit better. Your method looks very good. But the Tesla has 400 kW power. I'll get a professional welder to do this.
I have had better luck with no sleeve. Keep a constant cross section so that the whole thing twists evenly and there aren't any stress risers and they will live a long life.
Hello: I have been enjoying watching your build process. I am currently build two buggies, one with a 40 horsepower snowmobile engine and the other with a 95 horsepower snowmobile engine. I am struggling with getting the correct axle situation with my 40 horsepower buggy. Let me ask you, how has the welded CV axle held up? Can it take some serious power? I agonized over splicing my axles but many comments I have read state that welded CV axles only hold up in lower power applications. I am using RZR transmissions in both my buggies so that won't be a problem. My 95 horsepower buggy will be using all stock RZR suspension parts so there won't be a durability issue with that buggy. I'm debating on custom splining a CV axle so I can have an inboard RZR CV joint and an Arctic Cat ATV outer CV joint to go with my ATV suspension on the 40 horsepower buggy. Welding the halfshafts would be easier, but I am concerned that the first time I try to pull a wheely or floor the accelerator, my welded axle may snap. Your thoughts? Thank you.

I can agree however the welds one each end of the tube and the rosett welds should stop that,

Super ingenious your video deserves far more views. Thanks and subbed!

D Walrus thanks
I have actually done this and never broken one.
Degenerate Fabricators hey could you please message me !! I have just a few questions to ask you !

Thanks I appreciate it !!!

Most shops won’t however this is likely the best bet, no guarantee it’ll hit a ton of torque but it works good on other things.
Great idea, I’m building a cross kart using a Subaru rear CV, will be doing this
Hell yea do it!
That makes a ton of sense, I wonder if you drill 3/8' holes about 1' apart in the sleeve and weld there too willl it add strength?
Levi Schittlord yes roset weld
Good stuff sir
makes so much sense!! physics babby!!!

It’ll hold

Awesome! In my case I’m looking for a way to extend them, which I think is going to be more complex lol.
Same concept use a long sleeve that covers both splices with a long bar between the splice
Good idea
Can you do one for my car

Your thoughts?
Thank you.
When they say high hp they are talking 300+ the low torque num thx you’ll be dealing with I’d be confident with it.
Is it possible to use that same method on a rear end axle without the sleeve?????
No the sleeve is what keeps the ends from separating
Does having the added weight of the sleeve create any vibration?
It can but these are not ment for high seed over long distances
Degenerate Fabricators. So would I be able to notice it going 60-70 mph on the highway.
You may notice it but I’d think it’d be fine
How much Horsepower can you put to one of these?
Idk I’ve never seen one break.
Good to know! Doing an LS swap. I think you just saved me some dough.
My to short
