Low deflection properties of schmelke sks kielwood shaft?

[Bavafongoul]

It’d been awhile but it was because my friend returned the Schmelke Kielwood shaft for replacing the short ferrule
that is standard with a 1” Juma ferrule. He wants all of his pool cues shafts to be alike & have the same sight picture.

While this was being performed, he ordered a 2nd Kielwood shaft, flat faced version, and told David to ship both shafts
at the same time. He is experimenting with different tips than he has on his other cues & may change these some point.

Attached are photos of the two Schmelke Kielwood shafts he received earlier this week. The shafts are 30” long, 13 mm and weigh 4.6 ozs and 4.1 ozs.; threads are 5/16x14 and 3/8x10. Appearance wise, the shafts look really great.

Included is a photo of 3 shafts (my Barnhart RMS and his Schmelke Kielwood). The shaft in the middle is my Barnhart.
I hit with one his cues today and acoustically it sounded terrific. It was the on a Joss Color of Money cue butt (N7).

I liked the Schmelke Kielwood shaft. The finish was outstanding, it looked great, it hit like my Barnhart except for the
fact I have Kamui Black Clear with a soft tip and he plays with a medium tip. David delivered 2 perfectly straight shafts.

Since I am not able to persuade Cory to use a different approach and build me a big pin RMS shaft, I’m really inclined
to contact David Schmelke and order a Kielwood shaft. The quality seemed top notch and he’s much more affordable.

My closest friend has two Kielwood shafts from Schmelke. One is a 5/26x14 and the other is a 3/8x10, 30” length,
1”Juma ferrules, 13mm, Kamui Black Clear medium tips, and the lightest shaft is the 3/8x10 weighing just under
4 ozs. at 3.9. The piloted shaft was in the low 4 ozs. weight range. The shafts look great and I played with the big
pin shaft on one of my cues today. The fit was fine at the collars and my cues have a .840 diameter joint. I think the
Schmelke shafts look as good as any other Kielwood or Roasted Maple Shafts I’ve seen and the price is great too.

Unless Schmelke is drilling a hole in the front of the shaft, it won’t be low deflection.

An 11mm tip will be LD even without a hole drilled in the front.

Besides maintaining an annual membership at Fresno’s newest pool room, Sierra Pool & Bar, I am fortunate to also play regularly at Club Leland, my dearest friend. The sound system and music selection is incredible. Aside from streaming, he must have well over 600 CD’s and LPs to choose from and his man cave set up has speakers mounted everywhere.
Besides great ambience and friendship, his home setup plays tough with relatively tight Olhausen pockets (4 1/4” CP).
The 3 cues in the photo now include an extra shaft, i.e., Kielwood. FYI, I’m also ordering a Schmelke Kielwood shaft.

An 11mm tip will be LD even without a hole drilled in the front.

It'll be lower deflection compared with the 12mm shaft (assuming similar wood densities). I don't believe the tip width where "low deflection" begins is commonly agreed.

To compare the deflection of solid with drilled tips we need to compare cross sectional areas (mass) - how big a hole in the center = 1mm of removed outer diameter? For instance, reducing a 12mm tip to 11mm removes the same amount of material as drilling a center hole 4.8mm wide (leaving walls 3.6mm thick) - here's a scale drawing of the comparison.
