Driver loft as a number the ball actually sees
A 10.5 stamp is a nickname. Into a Lehigh breeze a delivered 9.2 launches like a different club, and a delivered 12.1 balloons like a moral failure. We clamp the head, write both numbers, and only then talk about opening or strengthening the face.
What we measure on a driver
Face loft, not the crown decal
Adjustable sleeves add a third liar. The sleeve click is a relative move; it is not an absolute loft. We seat the head in the jaws at the click you actually play, read delivered loft, then decide whether to click, bend, or leave it. Bending an adjustable hosel is a last resort — most of the time the sleeve already owns the window.
Players from Emmaus often arrive with a “set to 9.5” that still delivers eleven because the head was born weak. The mill ticket catches that before anyone buys a heavier weight.
Typical driver mill ticket
- Stamp and sleeve setting, copied exactly
- Delivered loft at that setting
- Whether a click would get you there without metal
- Launch window after the change
Spin talk is allowed after the loft is honest. A head that is two degrees weak of stamp will spin like a weak head no matter which shaft story you tell on the ride over from Whitehall. We would rather restore the window than sell a new stick that repeats the same paint lie.
Ticket: usually a Single Jaw Bend. A Stamp Audit is enough if you only want the delta on paper. Saturday can hold a driver. It cannot hold a driver plus irons.
