Hooke Jjoint Driveshaft - why?

[vincereynard]

It's a mystery to me!

This is a serious question and not an attempt to rattle any chains. I simply do not understand why anyone would
choose to fit hooke joint shaft, with the unavoidable addition of nasty sliding splnes, when a proper CV joint driveshaft is available for much the same price.

The CV joint was developed, as far as I know, to correct the horrors that hooke joints cause on FWD cars. They may be OK (ish) in situation where the angles involved are small and not particularly variable - such as a Pro. shaft. The deflection of Elan driveshafts are not small.

What am I missing? Why does anyone bother with them when an far superior alternative is available?

P.S. Sorry about the typo in the heading, I'm stuck with only using my left for a while! (Which is far trickier than one
would imagine unless experienced!)

They are required if you are running a FIA compliant 26R clone type racing series. Beyond that I agree CV's are a superior modern solution to Donut problems but some people just like something more original and from the period.

What Rohan says, and my brother in law did some research recently and found (in the UK) that having a two UJ plus sliding joint drive shaft made up by a prop shaft specialist near Heathrow was significantly cheaper than a two CV shaft. Money talks!
