I was wondering the difference between the basic and actual vertical center of gravity. Does the VCOG adjustment come from a combination of other measurements? Or a specific design feature of an iron head? Looking at some of the irons measurements side by side, I’m not able to see a specific correlation between a measurement or combination of measurements that seem to effect the actual VCOG; I would hope that if there was one, I would be able to spot it. :\ Thanks in advance.
Also, congrats on getting the new website up and working. It looks great.
The basic vertical center of gravity is the vertical distance from the ground line to the balance point on the face. the Actual vcog is is loctated somewhwere on the same plane. The same plane means that if we extended a 90 deg. line through the balance point on the face it would intersect the actual vcog. This is described in Ralph’s MPF book. Pages 34 thru 37 of that book explain the calculation. I could try to copy, or paraphrase all the info here, but I think the illustrations and formulas would help greatly in the understanding of the numbers, so I would suggest you take a look there. If you do not have the book, I will try and get PDF’s of those pages posted so you can review.
