Chocolate Halfshafts?

[AndreK]

Would anyone with suitable boffin credentials be able to confirm, for the Ital axle;

1. The exact material spec' that they are made of;

2. The approximate length of the shaft

3. The rigidity modulus of the material if possible

 

Many Thanks

And if you are still having problems you could always buy my Ital axle which is still available in the 'For Sale' section

Sorry about that blatant hijack but need the room in the garage and couldn't miss the opportunity 😬

In the Marina days they used to made from "EN8" which is a medium carbon steel possibly in an R condition. The current equivalent is 080M20.

 

I think the final production series when they were manufactrued at Canley used EN43 but if you want to improve strength and have shafts made you could try EN24T.

 

The "Young's Modulus" (E) of all carbon steels is nominally 207GPa. You can't significantly change modulus by heat treatment either so the twist in the shaft will always be identical for a given torque, if you don't change length or diameter, regardless of the composition of steel that is used.

 

Obviously the strength can be changed but EN24T is probably as far as you want to go without reducing the ductility of the steel too much.

 

Don't recall the length.

Chris...Many thanks, just what I needed

Damn.

Thought this was a thread for a new Christmas tree decoration!
