So i’m relatively new to club making, and am learning as i’m going. some things are pretty straight forward.. some not so much :)
what i’m struggling to figure out is I currently play Taylormade R7 TP irons and my 7 iron is set at D1 with a FST 115 shaft and Golfpride 2G midsize grip, I built a new 7 iron Maltby Forged TS-1 to see if I would like it. I built the new one using the same shaft/grip set up and shaft length. why is the swing weight off by so much (the new one comes in at D5+, almost D6)? based on the swing chart it looks like I would have to add 16-20g to the butt to make it a D1, but would you say that change is a “material change” to the overall static weight of the club, or is that normal to have to add that much.
Not sure what could cause that much difference, other than the TM head weight is significantly lighter. The TS-1 head weights are pretty standard to what we have always done. I know TM and other OEM’s have crept up club lengths over the years on some models, and when they do that they have to make the heads lighter. If the shaft is the same and the grip is the same and the length is the same, there should not be a 4 to 5 swing weight difference. Before counterbalancing to get it to D1, double check the lengths. I know you stated they were the same lengths, but just to be sure and to eliminate length as the culprit, I would double check. Beyond that, assuming the grip and shaft weigh the same as the components in the TM, the only thing it could be is head weight.
