Shortened driveshafts

Due to a miscalculation on my part I need to shorten some standard Renault 25 turbo driveshafts. I intend to chop them, sleeve and weld. Somewhere, can't remember where I read it was best to have the sleeve ends at 45 degrees presumably to maximiise the weld length

Do you think it's likely that the SVA would have a problem with home welded drive shafts?

If you've done a good job I don't see why it should be an issue. Some manufacturers sleeve them so should be fine.

I can't find any distinction in the SVA manual with respect to home made vs professional made vs massive manufacturer made. Every component is taken on it's merits.

Having said that they do have the power to fail anything they consider dangerous (either to you, a passenger or another road user)

Unless you are putting monster torque through the driveshaft it should be fine. If your really want to guarantee a first time pass get some made up by GB Engineering (this is also a good backup plan if you fail on your modified ones).

If you do make them, take pictures so they can see what you've done.

I'd be tempted to file a square (or probably round so as not to get a stress raiser) and put a small bar in the middle as well to help transfer the power.

Bear in mind i'm no engineer - this just seems a good idea to me.

They made my driveshafts - excellent quality at a reasonable price
