Taper Roll???

What is the best way to get rid of taper roll? It seems to me that about 60% of the shaft we are playing with today has a taper roll. How would you cure it?


Thank you!
 
Why would you need to? If it's a mental thing, don't ever roll them on the table and you won't know it's there. Rolling them on the table isn't going to tell you much about straightness anyway unless the shaft is shaped like a banana.

true,you need to look down them like you are sighting a rifle to test for straightness or spin them in a lathe.
 
Banana Shafts????

I check them on my lathe also..;)

I'm with Jer on this one because to my mind, there is no such thing although some might find it a convenient buzz-word to describe what's happening when they can't otherwise explain why a cue rolls funny.
 
runout and total runout

From ANSI standards Y14.5 GD & T (Geometric Dimension and Tolerancing)

refer to: http://www.efunda.com/DesignStandards/gdt/cylindricalspecs.cfm

Runout refers to the result of placing a shaft on a spindle such as a lathe, and rotating the shaft about its central axis while measuring with a dial indicator its surface deviation from perfect roundness. With circular runout, the dial indicator is not moved along the direction of the axis of the part. Circular runout is therefore applied independently at each station along the length of the part as the part is rotated through 360 degrees.

Total runout involves moving the dial indicator along the length of the shaft while the part is rotated, so that it controls the cumulative variations of circularity, cylindricity, straightness, coaxiality, angularity, taper, and profile.

could be a table that isn't completely level or a wrap issue or?
Blaming the wrap is the same as "taper roll". If it's warped it warped, meaning both are myths...

Hi Paul; You're not telling us anything we don't already know. The question is about a phrase I've never heard of. WHAT IS "TAPER ROLL"?...JER
 
My guess

I could be wrong but I think that taper roll is a description or term used to sell a cue that has a shaft or shafts that are not straight. Most buyers won't buy a cue that have shafts that wobble or flop when rolled on a pool table. Thus the seller will describe the shafts as having a "taper roll".

Shafts and/or butts............
I believe I remember this phrase surfacing around a certain type of non conical taper used on the butt. Some of the explanations were actually kind of humorous.
ie...."turns perfect between centers but has a slight taper roll when rolled on a table"?

So if it doesn't turn perfect between centers?........OH,....that's just a little taper roll left over from when I rolled on the table!

I don't know........to me... they either roll straight or crooked....if it's not straight, you can call it what ever you want....BUT IT"S STILL NOT STRAIGHT!

Every cuemaker dead or alive that has ever built a cue has or will experience this at some point of their building them. It's just the nature of trying to keep some long, thin wood straight.

Hi Jer. I sent you a PM. I'm aware that you guys know GD & T. My assumption about "TAPER ROLL" is that they were trying to describe total runout.

Exactly Right!
You play using the outside diameter of the cue not the center line.
Ideally, they are the same but in the real world that is not always the case.
When you roll a cue you are rolling it on the outside diameter.
The real roll test is to place a cue on the pool table with the but on the felt and just behind the joint on the rail.
If you find one that does not have SOME tip run out using this method then you have an exceptionally straight cue and NO excuse why you missed that shot :eek:

If you sight down a cue like a rifle and it looks bent, it is.
If it dont look bent, it is straight enough it wont effect your play.
 
Hmmmm

Have other cuemakers or retail store use a specially designed cue spinning device checks each and every cue for true straightness? That is use by Mike at Discount pool cues.

Scroll to near bottom of page to see picture and explain why he use the cue spinning device.

Scratching my head wondering why someone would want to spin a finished cue 2500 rpm put together. :eek: :confused: If it's off a hair it is gonna flex and wobble like a sonnabatch.
