Club Building 101: Shaft tip diameters; sanding .370″ to taper
Every club head has a certain tip diameter designed for a specific shaft. As a club builder, it’s my job to know which shafts work in which heads, and also when to use certain tools — like a shim or a reamer — to get the optimum shaft into the club head to create the best fit for the player.
This video explains those processes, along with both hard and soft stepping. I also give you the definitive answer for sanding a graphite shaft to taper.

Putters that never made it: Check out some of the best tour builds that didn’t make the cut
Arguably, the best perk of being a professional golfer on the PGA Tour is the ability to request or even just be handed pretty much any club you could think of. It happens more often than you think, usually with putters around the practice green from one event to the next. Come Wednesday, the Tour bags lining the edge of the putting surface become resting places for fallen flatsticks that never made the cut.
So let’s take a look at some of the best we’ve seen out on Tour this year that never made it to the competition. (You may notice none of Hideki Matsuyama’s custom Scotty Cameron putters made this list. There are too many.)
Let’s start with this custom Damascus Milled Odyssey Rossie made for Ryo Hisatsune. Featuring a single line and the short-slant hossel, we’ve seen plenty of Number 7 and jailbird heads featuring the Damascus Milled insert, but this is the first and only one we’ve spotted in a Rossie. Hisatsune primarily putts with an Odyssey Black Series iX #9, but we have seen him recently with a TaylorMade TP Collection SOTO, so there could be potential that the Damascus Milled Rossie could end up in the bag.
Everyone wants to be Cameron Young right now. We’ve had Justin Thomas and Tom Hoge both game the Scotty Cameron 9.5R prototype. Well, for the PGA Championship, Brooks Koepka nearly joined that list after requesting the same style of putter, with the full-length alignment line. But the Scotty Cameron reps took the request a step further and made one specially for Koepka with a Teryllium insert, similar to one in his previous Newport 2 gamers. The reason why this one didn’t go into play, though? Because it was too heavy.
Harry Hall was the third-best putter on Tour last year, so when Bettinardi made him a custom proto, you know it was going to be good. The custom BB28 blade features VDF face milling, a custom-welded single-bend shaft, and the owner’s initials – HH – on the sole of the putter. Hall, who usually games an Odyssey O-Works #7 W, has dabbled with a TaylorMade Spider Tour X already this year. Maybe there’s a chance this Bettinardi might make his bag.
Honestly, this one doesn’t need a description. It’s Kieth Mitchell’s custom Scotty Cameron Napa. One Scotty Cameron face stamp, two Scotty Dogs, two Scotty Cameron 7-Point Crowns and one Circle T. That is all. Oh, except for the Cashmere Cameron headcover.
Finally, and just for fun, how about we pour one out for this TaylorMade Spider Tour X made for Scottie Scheffler in its new torched finish. It’s unlikely we’ll see a putter change anytime soon from the best golfer in the world. In fact, he hit just two putts with it on the Harbour Town practice before going back to his trusty gamer.

In our forums, our members have been discussing their favorite major winning irons used by Tiger Woods. WRXer ‘golferdude54’ kicks off the thread saying:
“Mizuno MP 14/29. Titleist 681T. Nike Forged Blades. TaylorMade P7TW.
Among these irons that helped Tiger win 15 majors, which is your favorite in terms of looks?”
And our members have been naming their favorites and why in response.
Here are a couple of posts from the thread, but make sure to check out the entire discussion and have your say at the link below.
- SwingBlade: “I prefer the early blades he played and the more recent TM TW’s especially because after Tiger had his major behavioral setbacks, part of Nikes support payback was making Tiger play a Nike putter and cease using his beloved uniquely customized Scotty putter.”
- ProjectX: “This (Nike Forged Blades) and there’s not even a close second.”

Or,,,, you can bore out your Irons to 370, much easier and the fit will be better. This guy is a Master Club Maker? Advocating this sanding stuff is BS. It ain”t easy to get it correct, and Taper tips are each make for a number. The design of the shaft is totally different.

To bore out the hosel of a taper tip iron head requires precision drill press , a couple of different size drill bits and reamer for accuracy and consistency throughout a set and even then, chances are some fits will be loose , very loose and others tight. A taper fit is always the same, if the tapers are accurately machined.

Correct Tony Dyck – the difference between parallel and taper is merely 0.015 of an inch. Anyone attempting this would logically use a good caliper gauge to the appropriate diameter and depth of the receiving hosel.

Shanking this video. Doesn’t explain enough and it leaves a lot of people still confused. You need more diagrams and actual footage of the parts you are describing and the work it takes to make, say, that 370 fit into the 355. And say that yes, it “fits” but it’ll never play the same or feel the same as a real taper tip that has a long taper section at the bottom 3 inches than the same 370 thickness of that parallel shaft.

Likely should have proofed this episode before airing it. I get it that it’s not easy, but the one that stands out is that you are only sanding off .015″ of the tip diameter and not .15″ (and only .0075″ off the radius).

Thank you for addressing issues that are not often discussed.
Suggest that the advantage of taper tip iron shafts is that properly machined tapered tip shafts inserted in tapered bore clubheads, are much more precise and consistent through a set of irons than parallel tip shafts inserted into clubheads machined for parallel tip shafts.This is basic knowledge in the machining business.
It is much more expensive as you point out to machine, sort and match taper tip shafts to clubheads; however if machined properly the taper fit will always ensure the shaft is perfectly centered within the hosel, close to “interference fit” throughout the set and there will not be looseness found in parallel tip irons.
IMO it is one of the main reasons golfers say that they notice a difference between forged clubs compared to cast iron heads. The difference in feel IMO, is due to more precise fit of shaft and clubhead with taper tip shafts in taper tip heads, which is common with more expensive forged irons. Cheaper cast iron heads more commonly will have parallel tip shafts in parallel heads. Its cheaper for the manufacturer.
So although mfg may say it is ok to grind or sand parallel tip graphite shafts to suit tapered tip iron heads, I suggest the precision inherent with irons with taper tip shafts precisely machined in the factory, may be lost when taper is done ad hoc for each shaft. If the irons are expensive forged, IMO dont compromise the feel for relatively small shaft cost savings.
