CV axles.
I have a question on them. Can they be cut down and welded together to make them shorter?
(maybe this should go in Open Discussion. I dunno)

stub axles....
You could do it but aware that if they aren't put back together totally strait and somewhat balanced you risk messing up everything in your rear end (pinion gears, all carrier mount points, etc.,). Even if each axle is just a 'little off' you probable wouldn't notice the destruction of your rear end right away. I'm voting NO to the idea.
Your mileage may differ..... . Cheers! Chris |

If you're still posting then I guess you're not banned then... joke custom user title?
I did think you were likely to be one of the last people here to be banned. As for the axles I guess they are forged. They seemed that way to me anyway if I remember correctly. I guess a weld would probably not be strong enough - or you'd need some chap who welds gas pipes for a living to do it for you.

Anything is possible given the right methods and procedures, but the axles would be out of balance and unless put in a jig, not straight either.
Are you trying to save a few dollars? What is the missing story here? If this is for something that wont be driven ever, then SURE.

Ok, Speeds will only be 4-5M/h less then a mile so it's doubtful anything oddball would happen. The story is. I diddnt get to build my mercedes Train. So I'm building (eventually) a Mercedes Railbus using bits and pieces from mercedes to make it go. Delibas coming out this way made it important to have somethign small for individual rides or small groups not to drag an entire train out.

You didn't explain why you wanted to do this? If they are the correct axels for your car they will not need to be cut.
That said - if you need room for the flux capaciter - maybe find a piece of steel that has an inside diameter similar to the outside diameter of the shaft and sleve it. This will hold it streight. |

See the last post I made. I explained WHY I wanted to do this....

You slide each end of the Shaft so that they met at the Mid Point inside of the Tube. After That you weld around the Tube ends to Weld the Tube to the Axle. ARC Welding might not be the best method to weld it.

I cut and welded a trans input shaft, worked decently all said and done. People do this stuff all the time for farm machinery and such, Im sure it will work out well.
You can also just disassemble and cut the axle, put the pieces in a lath, flatten the ends, drill and tap a hole down the center, champher then ends and thread them back together with a piece of threaded rod, then weld it up. Then it should be perfectly straight and even without too much difficulty. Would not be as strong as diesel's method, but both ways would probably work If you did that, I doubt you would have to bother with balancing, especially at that speed of rotation

I think the large end pops off with a lot of force, you could pop it off, take it to a spline shop and have them cut and respline it, but for just a train at 5mph... balancing is not going to be an issue. the thing I'm worried about is I think it's cast iron... at least it's high nickle content STRONG stuff. not sure if it can be welded or not.
I don't think it's forged... I think it's cast, and lathe turned to size. there is a weld of some sort where the boots rest, and another in the center... woldn't hurt to ask a welder their opinion. I'm a gas pipe welder, and I'd not tackle it. all ya gots to worry about with gas pipe is leaks!

I should have guessed this was a train related question.
You might find that process automation components - the sort of things used in factories - will suit your needs. I've seen length adjustable shafts (on splines) with universal joints at both ends before... There must be many more people who do this sort of stuff but here's one hit I got from google:- http://www.beldenuniversaljoints.com/?gclid=CJinvfOThakCFUOFDgodTnfHkQ

@Army, I'll look into that too. as for the train thing.... I'm using mercedes parts....so why not ask mercedes experts? I think an amusing Joke would be to put the whole thing (completed project) Taking it down to my indy and tell him to go over it. he wont but It'd be amusing.

Not saying this to be argumentive but I doubt if it is Cast Iron. It is too thin and Cast Iron tends to be brittle. Not the type of thing that is ideal for twidting and flexing loads. When you see an Axle like might be on a Truck that appears to have been Cast the Hub Flange is part of the Casting and the Shaft between the Bearing and Spined area is Tapered. There is such a thing as Cast Steel that does not have the disadvantages of Cast Iron but looking at the Axle it just appears that they used and Machined some sort of Steel Bar.
