I have decided to do my first reshaft on an R7 425 head I have sitting in the basement. I have a .350 driver shaft and the head, from what I have seen, is .350 as well. However when I insert the shaft (prepped, no epoxy yet) into the hosel there seems to be a lot of play. I have tried the same with an old Reax shaft out of an R7 and the fit seems much more snug. The question I have is how much play is too much? Do I need some sort of an adapter? Thanks guys and any help would be much appreciated
