As AustinWood explained the spherical end of the carden shaft has to be a good sliding fit in the pot and I've not seen one like that for decades, most aren't spherical and can be thrown in from 100 paces. So I chopped the spherical end off and I used the splined end of a Hardy Spicer shaft, off a Triumph herald, the same size as a Seven. Both shafts were machined to the same diameter and a steel sleeve about 4" long machined to suit which was shrunk on the ends. The sleeve needs to be at least 1/2" wall thickness or it may slip as my mark 1 version did. And make sure you get the length correct.
