I have a set of Hogan IPT’s with rusted and damaged shafts. Since I intend on playing them, I don’t mind changing to a modern steel shaft but do not know the correct tip sizes, straight or tapered, etc. I want to set them up with R or A flex.

I have a lot of work ahead of me to extract the old shafts so getting the materials pre-ordered will help. Do you have shaft  tip and length spec’s for these old clubs or point me to a resource? Ralph’s book only goes back to 1970.

(I am new to club making and this is my first effort so I haven’t asked the right questions, any help is appreciated!)

Thank you!
