I am looking for advice with regards to collared ferrules vs non-collared ferrules. My belief is that if a club hosel is machined to accept a collared ferrule, any reshaft job should be done using a collared ferrule, only. It is my opinion that merely filling the space between the machined part of the hosel and the shaft with epoxy and using a non-collared ferrule will not provide the same level of shaft support intended by the club engineers. I have heard some folks say that using epoxy and a non- collared ferrule is just as good. Please advise.
I would say using a collared ferrule on an iron that was made to except a collared ferrule wold be preferable, but not necessary. If properly done, with the right amount and type of epoxy, a non-collared ferrule can be used and in my opinion you are not loosing any shaft support. Collared ferrules are much easier to deal with in a production environment and tend to be fit really close the outside diameter of the hosel they were designed for, requiring less finishing.
