What is SST PUREing? Tour club builder Scott E.G. explains
As far as club builders go, there are few as knowledgeable or experienced as Scott Garrison—or as he is better known by his nickname Scott E.G.
Scott owns and operates his own independent tour equipment support trailer on the PGA Tour, which not only houses equipment for players including club components, but he is also the only tour trailer that has an SST Pure machine.
For those not familiar with the SST PURE process here is a quick explanation from the company:
“The SST PURE Shaft Alignment System analyzes the structure of any golf shaft and identifies its most stable bending plane or Neutral-Axis. When assembled in the clubhead in this SST PUREd orientation, the result is improved consistency from club to club within your set and set to set within your brand.”
To help explain the SST PUREing further and the benefits, we reached out to Scott to talk about how he uses his machine and what goes into the process.
GolfWRX: For the people who are not familiar, walk us through the PUREing process.
SEG: Golf shafts aren’t perfectly straight or perfectly round. The SST PURE machine analyzes the structure of the shaft by applying force at the tip and rotates to find the “stiffest” and “weakest” points of orientation. It then uses that information to find the axis at which the shaft bends and returns on the most stable plane.
The machine identifies this by marking the shaft so I, as the builder, know where 12 o’clock is and can build accordingly. The hard spot faces the target, 3 o’clock for right-handed golfers.
GolfWRX: How long have you been on tour doing it and has the volume increased over the years?
SEG: This is the start of my 18th season on the PGA Tour, and I have been PUREing shafts for 15 years. The amount of players utilizing this technology has absolutely increased. I’m one of the busiest trucks out there week to week because of it.
GolfWRX: What performance examples can you give us where a player PURE-ed his shafts and saw tremendous improvement?
SEG: It was about seven years ago when I just finished re-gripping Ben Martin’s putter with a SuperStroke grip. As he was leaving, I asked him if he had ever had his clubs PUREd. He said, “No, but I had heard about it and was curious.” I showed him a set I was in the middle of PUREing and he was sold. It was Monday morning, the week of the RBC Heritage and it was pouring. He said to PURE his entire set. That’s what I did Monday afternoon. I ripped his gamers apart and PUREd the shafts and put them back together (a retro-PURE). He was leading the tournament, he shot a career-low round and finished third. He told me later how much better his mis-hits were.
GolfWRX: What percentage of your work is PUREing golf shafts?
SEG: A very large percentage! I would say I spend the majority of my time in front of the PUREing machine.
GolfWRX: Being the SST representative on tour, how does your process differ from any competitors you may have—basically, people who “spine” shafts.
SEG: This is the most precise way to align the spine of a shaft, which is why so many utilize it. Any other process that is done by hand or “feel” can only be so precise. The SST PURE machine doesn’t guess.
GolfWRX: In your experience, what are the obvious benefits to PURE-ing your shafts? What should any player experience?
SEG: In my opinion, the obvious benefit to PURE-ing is decreasing mis-hits and tighter shot dispersion. If you hit a toe shot, you can still end up on the green. Shots seem to fly truer.
GolfWRX: A huge number of players on tour utilize the SST PURE system, do you think it’s more of a mental check for them or is it a vital ingredient to getting the clubs just right? In simpler terms, would a player notice if it wasn’t done?
SEG: Yes, most players would definitely know if a club wasn’t PURE-ed. These are the best in the world, and they have the ability to feel the difference. They know when a club head is half a degree flat or upright, they know.
GolfWRX: For players that are PUREing their shafts, are they doing it with just one club like the driver or is it every club in the bag?
SEG: If a tour player always has his shafts PUREed, it would be every club in the bag.
GolfWRX: Does the boom in shaft technology and quality make the PURE-ing process better or does it even matter?
SEG: They still need it. It’s the most precise and effective means to create the result.
GolfWRX: Do you think PUREing is something every golfer should do and why?
SEG: Yes. Golf is an expensive game and a large investment for every golfer in terms of money and time. It is more fun when you hit longer, straighter shots.
I’m going to gush in this intro paragraph, to get the emo stuff done early. I’ve not pulled harder for a professional to win, than Cameron Young. I coach golf in New York state, and each spring, my best golfers head to a state championship in Poughkeepsie. I first saw Cameron there as a 9th grade student. I saw him three more times after that. I reconnecected with Coach Haas from Wake Forest, an old interview subject from my days on the Old Gold and Black, the Wake newspaper. He was there to watch Cameron. After four years at Wake Forest, Young won on the Korn Ferry Tour, made it to the big tour, almost won two majors, almost won five other events, and finally got the chalice about 25 minutes from the Wake campus. Congratulations, Cameron. You truly are a glass of the finest. #MotherSoDear
OK, let’s move on to the Tour Rundown. The major championship season closed this week in Wales, with the Women’s Open championship. The PGA Tour bounced through Greensboror, N.C., while the PGA Tour Americas hit TO (aka, Toronto) for a long-winded event. The Korn Ferry lads made a stop in Utah, one of just two events for that tour in August. The many-events, golf season is winding down, as we ease from summer toward fall in the northern hemisphere. Let’s bask in the glory of an August sunrise, and run down a quartet of events from the first weekend of the eighth month.
LET/LPGA @ Women’s Open: Miyu bends, but she doesn’t break
Royal Porthcawl was not a known commodity in the major tournament community. The Welsh links had served as host to men’s senior opens, men’s amateurs, and Curtis and Walker Cups in prior years, but never an Open championship for the women or the men. The last-kept secret in UK golf was revealed once again to the world this week, as the best female golfers took to the sandy stage.
Mao Saigo, Grace Kim, Maja Stark, and Minjee Lee hoped to add a second major title to previous wins this season, but only Lee was able to finish inside the top ten. The 2025 playing of the Women’s Open gave us a new-faces gallery from day one. The Kordas and Thitikulls were nowhere to be found, and it was the Mayashitas, Katsus, and Lim Kims that secured the Cymru spotlight. The first round lead was held at 67 by two golfers. One of them battled to the end, while the other posted 81 on day two, and missed the cut. Sitting one shot behind was Miyu Yamashita.
On day two, Yamashita posted the round of the tournament. Her 65 moved her to the front of the aisle, in just her fourth turn around a women’s Open championship. With the pre-event favorites drifting off pace, followers narrowed into two camps: those on the side of an underdog, and others hoping for a weekend charge from back in the pack. In the end, we had a bit of both.
On Saturday, Yamashita bent with 74 on Saturday, offering rays of hope to her pursuing pack. England’s Charley Hull made a run on Sunday closing within one shot before tailing off to a T2 finish with Minami Katsu. Katsu posted the other 65 of the week, on Saturday, but could not overtake her countrywoman, Yamashita. wunderkind Lottie Woad needed one round in the 60s to find her pace, but could only must close-to’s, ending on 284 and a tie with Minjee for eighth.
On Sunday, Yamashita put away the thoughts of Saturday’s struggles, with three-under 33 on the outward half. She closed in plus-one 37, but still won by two, for a first Major and LPGA title.
PGA Tour @ Wyndham: Young gathers first title near home
Cameron Young grew up along the Hudson river, above metro New York, but he also calls Winston-Salem home. He spent four years as a student and athlete at Wake Forest University, then embarked on tour. This week in Greensboro, after a bit of a break, Young opened with 63-62, and revved the engine of Is this the week once more. Runner-up finishes at the Open, the PGA, and a handful of PGA Tour events had followers wonder when the day would come.
On Saturday, Young continued his torrid pace with 65, giving him a five-shot advantage over his closest pursuer. Sunday saw the Scarborough native open with bogey, then reel off five consecutive birdies to remind folks that his time had, at last, arrived. Pars to the 16th, before two harmless bogeys coming home, made Young the 1000th winner of an official PGA Tour event (dating back to before there was a PGA Tour) throughout history. What’s next? I have a suspicion, but I’m not letting on. Mac Meissner closed with 66 to finish solo 2nd, while Mark Hubbard and Alex Noren tied for third.
Korn Ferry Tour @ Utah Championship: Are you Suri it’s Julian?
Who knows exactly when the flower will bloom? Julian Suri played a solid careet at Duke University, then paid his dues on the world’s minor tours for three years. He won twice on two tours in Europe, in 2017. Since then, the grind has continued for the journeyman from New York city. At age 34, Suri broke through in Beehive state, outlasting another grinder (Spencer Levin) and four others, by two shots.
Taylor Montgomery began the week with 62, then posted 64, then 68, and finally, 70. That final round was his undoing. He finished in that second-place tie, two back of the leader. Trace Crowe, Barend Botha, and Kensei Hirata made up the last of the almost quintet. As for Suri, his Sunday play was sublime. His nines were 32 and 31, with his only radar blip a bogey at ten. He closed in style with one final birdie, to double his winning margin. Hogan bloomed late…might Suri?
PGA Tour Americas @ Osprey Valley Open presented by Votorantim Cimentos – CBM Aggregates
Some tournament names run longer than others. This week in Toronto, at the Heathlands course at TPC Toronto, we might have seen the longest tournament title in recorded history. The OVOPBVCCBMA was a splendid affair. It saw three rounds of 62 on Thursday, but of those early risers, only Drew Goodman would stick around until the end. 64 was the low tally on day two, and two of those legionnaires managed to finish inside the top three at week’s end. Saturday brought a 63 from Patrick Newcomb, and he would follow with 64 on Sunday, to finish solo fourth.
Who, then, ended up winning the acronym of the year? It turns out that Carson Bacha had the right stuff in TeeOhhh. Bacha and Jay Card III posted 63 and 64, respectively, on day four, to tie for medalist honors at 23-under 261. Nathan Franks was one shot adrift, despite also closing with 63. If you didn’t go low on Sunday, it was about the check, not the championship.
Bacha and JC3 returned to the 18th hole twice in overtime. Card nearly chipped in from the thick stuff for birdie, while Bacha peeked and shoved a ten-feet attempt at the win. On the second go-round, Card was long with his approach, into the native grasses once more. He was unable to escape, and a routine par from the fairway was enough to earn the former Auburn golfers a first KFT title.
Card III and Bacha both miss their birdie tries on the first playoff hole.

Gotta give props to maintaining a 15-year scam. Shafts have not had a spine for over a decade. Plus, the manufacturing variability from shaft to shaft is FAR greater than the error in concentricity in a single shaft. Even if you “pure” all your shafts, they are still going to be different from each other. Where is the data that shows measurable gains in a pure set vs. a standard set? Right…. doesn’t exist…
That said, if you believe it’s better, it probably is.

If a $300 shaft needs to be pured, its not worth buying and cheap $10 shafts that come from “off the shelf” sets arent worth the extra cost.
Better to buy a shaft thats made properly without a seam. eg Nunchuk

If it’s really that important how come every pros shafts I see in action on tour have all their shaft logos straight along the underneath of the club as if they’re in the standard installation position?
It also makes no sense if you adjust your club and spin the shaft to change the loft. Then what?
Lastly. Your goin to install a high end $300+ driver shaft and a simple rotation of the shaft to “pure it” canst be done by the manufacturers? Why to they make off a line on the bit of the shaft be fore it’s logo is painted then? Why because they do this for you. puring shafts post production is the biggest scam going right now. Heard about it and witnessed it 20 years ago and it’s still not a must for all top players for a reason. Skip it and go practice more.

Pureing may have been beneficial when graphite shafts made 20 years ago as the manufacturing back then wasn’t as consistent but totally unnecessary now. It’s not gonna hurt your game if you get your clubs Pured, but won’t help either.
