The lad who built this?

Yes but it needs to be done right on a lathe to ensure accuracy. The last thing you want is drive wobble when pelting around a track at ludicrous speed. The ones we got made up had an interference fit dowel inserted into the two halves before it all got welded up just to be safe.

SCCH made me spacers to added in when the shaft is cut and extended with them spacers. He told me he made spacers for that vtec corrado too.

Murray told me of a place in park west that will do the welding on them. They will actuall do all custom work on shafts too. I dont know his username on here though.

I never thought of dowels being inserted i was thinking welding alone wouldnt be enuf
I need to get existing drives made approx 80mm longer so was hoping i can get complete shaft made and maybe 2 spares,
its for rallycar which i hope will put out 250bhp ish so want good drives for it,
i will prob extend the shafts i have to test clearance etc then get new shafts made to new length

I made a set of shortened shafts for a hill climb car some years ago. It had somewhere around 275 or so BHP. The process is simple but great care is needed in the welding as the shaft will bend with heat. They are still in the car 20 years later.

Machine shaft where the cut is to be made
Cut shaft
Drill to take interference fit dowel
Chamfer shaft ends
Machine up a sleeve which will fit over the welded area
Fit sleeve over one piece of shaft
Press in dowel to one piece and press the two shaft pieces together
Tack weld the two pieces together.
Weld along the shaft on one side
Weld along the shaft on opposite side
Check
Weld along the shaft on one side 90 degrees from last weld
Weld along the shaft on opposite side
Check and repeat this till the welding is complete.
Use rods suitable for high tensile steel
Machine shaft and slide sleeve over weld
Weld sleeve to shaft

If you have a slight bend in the shaft it will break something. Any decent engineering shop should be able to do it!
