I am on a seesaw and I weigh 250 lbs, the person on the other end of the seesaw
weighs 100 lbs. in order for the seesaw to have even balance, our goal, we have to add 150 lbs to the 100 lb end
I have a shaft on a fulcrum, the tip end of the shaft with the head is heavier than the butt end, the goal is equal balance, so I have to add something to the butt end to bring it into balance. The scale I am using right or wrong, says the club is e4 and I want it to read D4. So I put a banana on the butt end, but, I still need more, problem is the bananas are not all the same. So I decide to use a dime. I add one dime down on the butt end and the scale reads e3. It will take 10 dimes to get to D4.
now, whether D4 has been implanted by an alien creature or not, the fact remains that the weight of the dime changed the reading. It changed the reading....the guy on the seesaw moved to equal........there is nothing relative here except the scale itself
the dime changed the reading. The dime is actual and not theoretical. I will assume you have never used a swing weight scale and given it the dime test. Just so you know, whether the dime is heads or tails doesn't matter.
Again, total weight is always more important............. good nite Brian

If you put the dime on the "grip end", it will "weigh" only about 1/3 of what it would "weigh" on the Clubhead side (using a Driver). Again, the Fulcrum is at 14". (For simplicity's sake, L X W = moment.)
Read Archimedes Law of the Lever. ( Archimedes' Law of the Lever)
Which is why a Telephone Pole can have the EXACT same Swingweight, as a Taylormade Driver.
I'm not a fan of Dave Tutelman, but he does a good job of explaining exactly what a Swingweight Scale measures and why: Design Notes - Heft: swingweight and MOI p1
FYI, this is also the theory behind "counter-weighted" putter grips or counter-balanced putters. By placing weight directly under the top of the grip, you can "fool" the Swingweight scale. CounterCore Putter Weights |
