I'm with Steve on this, pulling shafts on Pings isn't hard, I do 3 at a time, use a propane torch and heat one up, move to the next, then on to the next, back to the first one and do that 3 times total, it lets the heat sink in to the metal more and that generally gets the bond to come loose nicely with no browning. I do the three at a time method because I'm impatient and WAITING for heat soak is too much for me to handle, keep busy with others and it's fine. Takes about the same time as any other club if you do it this way. I typically will something similar on graphite pulls, but I pre load into the puller, put it under a little pressure, heat a little, let it sit, little more pressure, heat if it's not loose, and so on, I hate burnt hosels so I go slow.
