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.

From the Forums: How are you liking TaylorMade’s Qi10 fairway woods?
In our forums, our members have been discussing TaylorMade’s new Qi10 fairway woods. WRXer ‘ace036’ plans on testing them in the next few weeks, saying: “from how they look from address and frame the ball is much more appealing to my eye versus my current Paradym fairway woods.” And our members have been sharing their positive feedback in our forum.
Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.
- Edwardsr: “I got fit into the Qi10 core model with Ventus TR Black 8X and it’s absolutely amazing for me.During the fitting with my 12-15 swings with it, it was the most efficient combo I’ve ever tested, tons of 1.48 smash and 3 or 4 1.49 smash (which I don’t think I’ve ever gotten on 3 wood on a launch monitor).”
- MiloMalt: “No complaints and so far only high praise for my Qi10 Tour 3 and 5 wood. I’m getting great numbers and a nice penetrating ball flight with great height whereas with my old TSi2 4 wood it was spinny and ballooning and short because of that.”
- courcy75: “The Qi10 Tour 3 wood I just put in play has been outstanding for me. Finally found something I like as much as the 07 burner tp.”

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.
