Luego used to shorten them for the IRS Locost , they did mine but I think if I were to build another with shortened drive shafts I would get new ones made . Think it was NSDev who posted a link for driveshaft manufacturers. May be worth a search?

Cheers guys for the replies

MK Engineering do them as well.

If the only option is shortening standard ones yourself then make sure you sleeve them.

I have never done this but it should work.

The problem with drive shaftsis welding is not really advised due to the steel involved.

Therefore you can sleeve the outside and use 638 Loctite high strength retainer. If you get enough surface area it should hold.

The other option is silver solder. It will wick in and hold.

Anybody brave enough to try it?

Obviously surface finish and prep is vitally important, as is making sure they are straight.

If anybody is seriously interested I will explain how I would do this.

All Stuart Taylors use shortened, sleeved and welded shafts, in fact i happen to have a pair for sale if your interested.... they are splined for lobros both ends.

Trust me - driveshafts can certainly be welded, I welded mine myself & I've broken a couple of bits in the drivetrain but not those, (see my thread under bec - bike engines have no torque ???!!!).
If they are solid steel. cut them get some interference fit sleeves, join at required length & a quick bead of weld at max power, Bob's your uncle, Fannys your aunt & away you go laughing
