Steve might be able to answer this or other Ping freaks but doesn't Ping still use the rubber mallet to adjust for lie? Do they use a L/L machine or adjust via mallet and measure on L/L gauges?
See at 6:00 mins with mallet and at the end measure with Green machine. Seems Ping does not use L/L machines as we think of them today. Shock the metal and it will retain lie/loft better than bending cast Karsten always said.
When a clubmaker orders from Wishon/Diamond Intl all measurements are done on a Green Machine after adjustments are made.
