Welding steering shafts?
I know this has been talked about before but I cant find the post....
Thought I might as well check.
Is it acceptable to get several steering shafts and chop and weld them together to make one decent shaft that fits the car?
My plan was to chamfer the ends of the shafts to be joined, weld them, grind it back and then weld a sleeve over the top...would that be ok?
My SVA tester mentioned that he didnt like to see weld on UJs, so provided I leave an inch of shaft between the welded section and the UJ I should be
ok?
Chears.

Welding and sleeving should be most acceptable as long as your welding has good penetration.
Just make sure you let it cool in its own good time and its straight.

Keeping it straight is going to be the biggest problem...
I dont want a banna shaped steering shaft!
What is the best way to prevent distortion when I weld it?

I've cut, sleeved & joined several - no bananas as yet
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

Isn't this standard MK practice on Sierra shafts for the Indy - mine was cut and welded by them as an echange anyway.
It wasn't sanded or cleaned before welding, but it was sleaved. It's been playing on my mind for two years since watching them do it and
I'll be taking it out, grinding it down and getting someone to re-weld it before I take it for SVA!

Mine is tube, with the correct joints turned down to fit into the tube , leaving about 3mm clearance for weld to pentrate into.
As long as the wall thickness is strong enough then no bending.

At my work we manufacture steering extension shafts and do indeed weld the tubes to the yokes, however this is after the yoke has been pressed onto
the tube with a minimum 5Kn and before the bearings and rubber seals are inserted. Target insertion force is 15Kn, 5Kn lower, 25Kn upper limit.
If you want weld close to the yoke put it into a bucket of water to cover the bearings.

i make a press(ish) fit tubular sleeve, then cut the ends at 30-40 degrees, press the shafts in each end and weld the remaining angled fillet.
spreads the shear plane along the edge of the heat affected zone, as well as lengthening it
