Iron Set Geometry

Why the whole set, and not just the seven iron

Almost every fitting you can book elsewhere resolves lie angle from one club and then applies a blanket adjustment to the rest. That works if the set progresses cleanly, and sets rarely do. Shaft length changes by half an inch per club, which changes how upright you stand; head mass changes; offset changes; and in blended sets the long clubs may come from an entirely different chassis than the short ones. The result is a bag where the pitching wedge is dead straight and the five iron leaks right, or the reverse.

We tape and strike every iron in the set. It takes longer and it is the reason this session runs two hours instead of one. What comes out is a per-club lie spec rather than a single number, and typically it is not flat across the set — there is usually a half degree of progression somewhere.

Reading sole tape honestly

A sole tape mark tells you where the club met the ground, not where the club was pointed. Those are different questions and confusing them is how players end up bent the wrong direction. A toe-side mark on a shot struck fat, for instance, is a strike quality artefact, not a lie problem. We throw out the fat ones, throw out the thin ones, and read what is left.

Six clean strikes per club is the minimum before we call a number. On a bad ball-striking day that can mean twelve or fifteen swings on some irons, and we would rather run over on time than bend a set off three data points.

Length before lie, always

Lie angle and length are coupled: lengthen a club and the effective lie goes more upright, shorten it and the toe drops. Fitting lie first and then changing length undoes the work. So we settle length against your wrist-to-floor measurement and your address posture, extend or shorten if needed, and only then read the board.

This ordering matters most for players outside the middle of the height distribution, which in practice means most juniors, most women fitted from a stock set, and a lot of taller men who were sold standard length because it was on the shelf.

Bending happens here

The loft and lie machine is in the back of the shop, not at a regional service centre. Forged heads bend readily; cast heads bend within a narrower window and we will tell you honestly if yours is at its limit. Either way you are not waiting three weeks for clubs to come back from somewhere else.
