The new rac os irons have an inner hosel sleeve made of steel similar to a shim that protrudes above the top of the hosel about a 1/4" and makes ferrule mating a bitch on a reshaft.
I've done these and the secret is to save the old ferrule. See instructions for making a tool to save ferrules in this forum. It will cost less than $5.
If you got bold and cut off the ferrule the secret to fitting a new one is to heat the sleeve and with a new ferrule on a shaft and the shaft dry fitted into the hosel, press the new ferrule down on the heated sleeve while rotating the ferrule. The new ferrule will melt into position. Do them one at a time and mark the ferrules for the club that it was fitted to since easch ferrule is "custom fitted".
