Re-tipped cartridges

A retip is actually the substitution of the existing cantilever/stylus combo with some other combo. The manufacturer produce them as a complete unit. They are than put in the tube behind the cantilever and glued.
This seems to be more easy to do then to glue the stylus
alone in the existing cantilever. In the aluminum cantilever the stylus can be 'pressure fitted' which means that the use of glue can be avoided and a better connection
between the cantilever and the stylus achieved. By the so called 'exotic cantilevers' (boron, ruby or sapphire,etc) the stylus can be only fitted with glue. As Syntax already pointed out the quality of the styli is very important.
That is to say not only the stylus shape but even more important the quality of the diamond and its manufacturing (polishing,etc.).
Raul has the most experience with retipping so I hope he will contribute to this thread.

The 'retip' in the past consisted in replacing the stylus only. The quality was dependant of the 'quality' of the master or his craftmanship. Since the manufacturers produce the cantilevers with styli already fitted the 'retip' become the substitution of the old cantilever/ stylus combo with the new one. This work is more easy to do and is consequently cheaper. The real question is this: how much glue is used in both alternatives? Or, to put this question otherwise, is the stylus better fitted by
the manufacturer or the cart repair service? Then the added question is which repair service can or will do this job and at what cost.
Dover's story imply that by the so called 'exotic' cantilevers the retipper need to use small diamonds and more glue in order to prevent 'fracturing' of the cantilever. But between this diamond and the cantilever there is glue and hardly direct contact between them.
As J. Carr explained in this thread the advantage of aluminum cantilever is exactly 'there'. The stylus can be pressure fitted without any glue.
