Hi looking for someone who has access to a lathe to turn down some drive shafts or to do the necessary to cut and join shafts and sleeve.
Maybe someone on here can help who has maybe done there own, willing to travel and pay beer money.
I'm in Coventry West Midlands but willing to travel to the right person, this will probs be in the next couple of months but trying to plan ahead, thanks in advance.

I could do this, not machined any before though
I assume it's just a case of turning down to a specific diameter?
If you can get them to me I'll do it

Hi thanks Ivan, can I ask where your located.

Oh and yes the thicker shaft just needs turning down to the same thickness of the mini shaft but there's not a lot to take off the doner shaft to match mini shaft thickness, then just need sleeving.

No worries

That's not how I'm planning to do mine.
I plan to turn one end with a hole and a press fit pin on the other. When pressed together there will be a V at the join. Then weld it up an then check it for true. Turn down the weld and slide a sleeve over and weld that.

Hope that all makes sense!

Yep that makes perfect sense, I'm going to try some engineering places but if that fails I will be begging everywhere.

It might be worth trying brand mechanic engineering in Bham. They specialise in custom drive shafts, but they would certainly be able to help turning yours down to size.

Hope you don't mind me asking this on your thread.
Does anyone know anything about hardening shafts after machining new splines? This is another option I am considering.

[matty...]

It all depends on what the material is to what process is used. Something like EN24 EN30 EN36 is easy enough to get hardened through heat treatment or chemical hardening. As above speak to brand mechanical engineering, they made my gearbox shafts for my custom box, and very reasonably priced.

The usual method is to turn down one or both shafts to fit a sleeve, weld it up (or force fit or even glue) and just use it as a dimensional check. Cones removed, operate suspension and steering over full travel, plus shift engine on its mounts, to check that inner sliding joints (pots on Mini, tripod on many donors) neither bottom nor get near to disengagement.

Then the shaft goes off as a model to your chosen manufacturer, to be replicated in the proper grade of steel, with hardened splines.

Sorry for the site jump but Aband is back on the scene after 2 years away give him a pm he'll be able to help you. ps some of his shafts are on the second and 3rd engine's!
