Hi Mcgolf,I’m reshafting a set of jack nicklaus irons,from about the 1970’s.I can’t remove 2 shafts.They are completely solid.one has the shaft complete and the other is broken at the hosel.I have tried drilling but it doesn’t seem to work.I used to chip them out with a obo nail,but took ages.How would you get them out,do you have any tricks.Thankyou in advance
