As I understand it, the brass splint is internal, inside the hollow cantilever, like a Kuntscher intramedullary nail passed through a femoral shaft fracture.
Use of a splint when changing cantilever and stylus
There’s a thread on another forum claiming that a well-known cartridge repair person sometimes uses an internal brass splint to join a new cantilever to the stub of the old one. Participants are horrified by this as it is said to ruin the sound of the cartridge. On the other hand, this repair person has an excellent reputation, and I have been delighted with work done. I don’t think there is any benefit in naming names and casting aspersions, so I shall not.
Is this a common method of attaching a new cantilever, and if so is there a better splint material to use?
