I am doing these later this week. I have done it before using a 3/8" Cobalt drill bit on slow RPM with cutting oil and I am doing these with a Golfworks .370 hosel fluted reamer bit. It is easy - just be careful about not deepening the hosel. I marked my bit with a sharpie at the stopping point. The fluted reamer is not an issue - it is flat-tipped and stops at the bottom of the hosel. L & L Golf in GA (Ron Oneal) just refurbished these for me. $13/head. You can find him on eBay 👍

Of Note: Vintage PING purists will say I have killed the value of these, but they are for me to collect and play.

Release Love hose Zings.

I might reshaft mine later this year.

I'l post pics when these are done. You won't like what I'm putting in them, but you know me and loud colors.........
😄

      Additionally, I plan to use a 3/8" tap to cut some very shallow threads in the hosel - my theory is this will help with bonding. I have seen threads in Mizuno iron heads.

        It must be great to have some time on hands.

        I'm so busy, don't even have time to golf. May also try to find a part time job for moonlight. 42 grant for one year of tuition plus room and board for out of State graduate program, and I have one other in undergrad.
        I might say good bye to golf for a long long time.

            Release

            I have time because all our kids are out of college, married, working and providing grandchildren to us (their ultimate destiny), 8 so far......and I'm retired. At 64 years old, I seem to be ahead of some guys.......I'm truly blessed and thankful!

                Ream, ream, ream, ream. Do not drill. With a good reamer, reaming can be done by hand. No need for a drill press.

                I am a bit late for the party but here is a pic of some wooden clamps I use for reaming on my drill press. Just cut some "V"s out of some blocks. Poke the hosel up through the hole in the drill press table and clamp the blocks onto the hosel. I use "C" clamps but you could run bolts through the blocks with wing nuts. Do not lock the table down or clamp the blocks to the table. Just hold onto the blocks and allow it to flloat. That will allow the bit to remain self centering.

                    Look nice, Steve, but how much did you tip these? I would normally expect to see even 1/2 inch progression of the graphics. Yours appear to be 'grouped'.

                      Thanks! - I tipped them to achieve a constant C9 swingweight. That's how they came out.
