I've got a 57 retractable that I need to replace the dizzy on. I've been reading some of the threads on here about different distributors and have decided to give the windsor dizzy a try.

I bought one today $100 and as mentioned on other threads the shaft needs to be lengthened.

If I'm correct, the new shaft needs to be 90mm long, but I noticed that the new gear on the windsor dizzy is on a seperate shaft that has a tongue which fits into a grove on the shaft from the dizzy, also, the windsor gear has a long sleeve which acts as a collar over the tongue and grove coupling.

What I would like to know is do you really have to weld a new shaft on to it, or, can the new shaft simply be slotted into the existing grove on the windsor shaft, as long as i include a similar collar over the coupling???

Any ideas would be appreciated. Cheers ken.
