I am fixing some Ping Eye2+ irons. Someone reshafted them with late model Ping CFS steel shafts, and the heads are loose. I pulled one for inspection and cleaned it up. The fit is super loose, more so than a typical Ping. It is still tapered, it has not been reamed out to parallel. But I think maybe the person who did it was too aggressive with cleaning out the hosels and enlarged them. To illustrate, I cannot tap or hammer the shaft so it stays inside the hosel. The hosel is too big for that.
I'm looking for advice, particularly a method of shimming. There is no ferrule, keep that in mind. NOTE: Down at the tip, there does NOT seem to be any wiggle room. Therefore a typical brass shim is not going to fit, I don't think. Maybe I'm wrong about that. Solutions? Would it help to dimple the shaft? It probably would help it stay in place for the assembling, but I'm not sure if it would help beef up the mechanical joint in any significant way. -Don M
