The Logbook
Notes from the bench — plain explanations of the measurements that actually shape how a club feels and performs, written by the people running the scale.
The Rotational Fulcrum Golf Clubs Actually Swing Around
Why the point a club balances on and the point it actually rotates around during a swing are two different places entirely.
Read entry →Matching a Junior Set by Rotational Resistance
Junior sets get resized by length constantly and rebalanced almost never — here's what that gap costs a developing swing.
Read entry →Putter Inertia and a Quieter Take-Away
How head inertia changes stroke tempo on longer putts, and why lag distance control often traces back to the scale rather than the stroke.
Read entry →How a MOI Matching Scale Actually Works
Inside the counterbalanced fixture we use to read rotational resistance, and why it needs checking against a certified weight every week.
Read entry →Driver Forgiveness Is an Inertia Number
"Forgiving" is a marketing word for a measurable property — here's the number hiding behind it and how we test for it.
Read entry →Why Mixed-Brand Iron Sets Drift in Feel
Combining heads from two manufacturers is common and usually fine — except for the one variable most players never think to check.
Read entry →Put This on Your Own Set
Reading about rotational resistance is a start — seeing your own set's spread on the bench scale is where it actually clicks.
