Driver Bench
Head mass, raw shaft length and where the balance point sits once the grip goes on. We chase a repeatable strike pattern before we chase a number on the screen.
- Bench time110 min
- Heads pulled10 to 16
- Shafts on hand190 plus
Kinnickinnic Avenue, Bay View
A Milwaukee bench where the paperwork leaves with the club
Tour Spec Lab is a fitting room bolted to a build room. You hit, we measure, and then we actually assemble the thing on site: cut, plug, epoxy, swing balance, loft and lie. The sheet in your bag pocket lists what the club is, not what the catalogue claimed it would be.
- Bench hours this week
- Mon to Sat, one golfer at a time
- Typical turnaround
- Six to nine working days

Six benches, six different questions
Book one or work through the bagIron Bench
The set is treated as one object, not eight separate purchases. Length progression, swing balance progression and frequency slope all get written down before anything is glued.
- Bench time135 min
- Test heads22 models
- Slope target4 to 5 cpm
Fairway Wood Bench
Off the deck first, off a tee second. Sole camber and leading edge height decide as much here as loft does, and both are easy to feel and hard to guess.
- Bench time85 min
- Turf mats3 densities
- Lofts stocked13 to 21 deg
Hybrid Bench
The most mis-sold club in Wisconsin. We size it against the club above and the club below so it stops overlapping something you already carry.
- Bench time75 min
- Compared againstYour 5i and 5w
- Length stepsQuarter inch
Wedge Bench
Bounce and grind chosen against the turf you actually play, not against a chart. Bermuda sand is rare here. Wet clay and thick bluegrass are not.
- Bench time90 min
- Grinds on hand11
- Loft gapping4 to 6 deg
Putter Bench
Head mass against green speed, then lie and length against where your eyes sit. The stroke arc is recorded before we touch the neck or the shaft.
- Bench time70 min
- Head mass range320 to 400 g
- Roll surface11 ft stimp

The tolerance window we build to
Printed on every as-built sheet| Specification | Our build window | Common factory spread | Why it matters to you |
|---|---|---|---|
| Playing length | Plus or minus 1/32 in | Plus or minus 1/8 in | Length drives both lie at impact and the balance number you feel. |
| Swing balance | Half a point | Two to three points | Two irons in the same set that feel unrelated is almost always this. |
| Total mass | Plus or minus 2 g | Plus or minus 6 g | Tempo suffers long before the launch monitor shows anything. |
| Loft | Plus or minus 0.5 deg | Plus or minus 1.5 deg | A degree and a half is roughly four yards in the middle irons. |
| Lie | Plus or minus 0.5 deg | Plus or minus 1 deg | Start direction on short irons is mostly a lie problem. |
| Frequency | Plus or minus 2 cpm | Unpublished | Keeps the set feeling like one family from 4 iron to pitching wedge. |

A shop that runs on two calendars
Golf in southeastern Wisconsin gets roughly twenty-six usable weeks. That short season shapes how this shop is scheduled. From late April through October the bays are booked with fitting sessions and the build room runs behind them. From November through March the bays go quiet and the bench takes over: full rebuilds, set re-shafts, loft and lie corrections on clubs that have been bent by three seasons of range mats and frozen ground.
There is a practical reason to care about which calendar you land on. A November booking gets a longer, slower session and a build slot with no queue in front of it. A June booking gets you playing sooner but the bench is stacked, so turnaround stretches. Neither is better. They are just different trades, and we would rather you pick with your eyes open than find out from a voicemail in week three.
The other thing the climate changes is the numbers themselves. A ball tested at forty-two degrees on a windy Tuesday in April does not behave like the same ball in August. We record the ambient temperature on every session sheet for exactly that reason, and we say plainly which of your numbers are seasonal and which are structural.

What the as-built sheet actually says
Most golfers have never seen the real specification of a club they own. The sticker on the shaft is a marketing label. The number stamped on the sole is a nominal loft. Neither is a measurement. Our sheet is a measurement, taken from the finished club, on our bench, after cure.
It lists eleven fields per club. Six of them are things you can act on immediately: playing length, lie, loft, total mass, swing balance and grip build-up. The other five are for whoever works on the club next, including us in three years when you bring it back.

Marek Dziedzic
Owner, primary builder
Opened the shop in 2009 after eleven years in a club repair back room on the north side. Does the frequency and balance work himself on every set that leaves.
Renata Osei-Bonsu
Fitting lead, irons and wedges
Ran short-game clinics for a public course south of the city for six seasons. Handles the wedge bench and every set gapping session.
Tobin Vargas
Bench technician
Regripping, re-shafting, loft and lie corrections, and the tolerance audit that every finished club passes before it is bagged.
I brought in a set I had played for four years assuming they were fine. Three of them were more than a degree flat and my 7 iron was eight grams heavier than my 8. Nobody had ever put a gauge on them.

Dispersion tightened 6 yards
What sold me was that they told me not to buy a driver. I needed a shorter shaft in the one I owned and a grip that did not fight my left hand. That was ninety dollars, not six hundred.
Annika RestrepoWauwatosa, WI. Driver bench, June.
Centre strike rate up 21 percent
The sheet is the part I did not expect. I keep it in the bag. When a club got bent in a cart accident last summer I handed them the sheet and they put it back exactly where it started.
