Thanks Tflan for this reply

borethrough is a little smaller diameter than .335". That's so the slit
tip shaft can be captured without shimming. The plug in the shaft tip is
a piece of plastic. The ferrule is a "lipped" O ring. You can use a
rubber O ring for appearance if you don't have a plastic one, or you
could carefully slice the original O ring loose and reuse it.
Scrape the paint from the tip and shove it through for fit. Once you
have it set, slip the ferrule on, add the epoxy and shove the tip
through completely. Remember you have to get the tip far enough through
the head so that the entire tip is showing. I like to use a piece of
fish line to shim the assembly in place tightly. Then, on your belt
sander, grind the tip nearly flush with the sole. Epoxy a piece of
plastic plug and tap it into the shaft tip. Snip off the protruding bit
of plastic and on your 3M finishing wheel, finish the assembly flush.
Then wipe the whole thing with acetone and set the club aside. If you're
adding a plug to the butt end do it now, or later.
If you've never done one of these no sweat. Just take your time.

I have done Berthas before(I had to do a bore through for my PCS
Certification Exam 8 years ago )but can,t remember the stepped hosel
I don't really like just using an O ring as it leaves a little bit of
the shaft unsupported in a critical place
(golfworks Canada is 10 minutes up the road from my office the guys
there are very helpful but not very experienced or PCS Certified
---they just glue an O ring on for cosmetic purposes)
Callaway presumably changed to this special ferrule to provide a liitle
more protection for the shaft at the top of a very short hosel
I think I have an answer to the ferrule problem if it works I will post
it for everyone.
Thanks to everone concerned about me being" flamed out "but dont worry
I'm a Brit living in Canada in my younger days I spent some time
seriving with 3 Para in Suez Cypruss Jordan and Lebanon "Snipers "
there were a bit more of a problem.
