What exactly is "taper roll" ???

I have heard and seen this term used so many times. It doesn't really make sense to me.

Seems to me, regardless of the taper of a shaft or butt, it either is straight or it is not.

If it rolls off or has taper roll, it is NOT straight.

Please educate me!!!

:smile:
 
I could be straight as an arrow, but slightly out of true round, and will wobble when rolled. Two round components joined slightly off center will create a singular unit that's not a combined true round, but more of a cam, and will wobble when rolled. Either of these are taper roll. My interpretation of taper roll in the beginning was a shaft or butt that was straight as far as each end being on the same center, but could vary slightly through the taper. Could happen with sanding shafts, or cutting them with a dull bit. One side of the shaft may be harder or softer than the other side, which causes slightly more material removal on one side, which causes out of round egg shape, which looks like a wobble when rolled. Nowadays, however, taper roll is the term sellers use to describe a slight warp.
 
Well, I got a cue in for repair. It looks a nice cue,with even looking points etc. Then when I set it up and rotated it, the cue is not round. The maker has hand worked the area where the points are, to shorten the longer ones. In places the amount missing is about 0.8mm about a 32nd of an inch.
So when it is rolled, although the assembly is straight, you see light between the surface and the forearm area.
This cues origin is from the Philippines, is basically hand made. I wounder how many are made this way to even up the aesthetics and hence the term a taper roll.
There does not appear to be any warp in this handle at all . All the deviations from round appear to have been done for evening up the tapered point work.

Taper roll is a term sellers use when they want to convince you that the stick being crooked does not matter. Honestly, I'm not sure it does matter, but it sure is a mental distraction to shoot with a stick you know isn't at least reasonably straight.

Wrong again - taper roll is an effect one may observe when rolling
a cue that is straight but doesn't roll like your grandma's rolling pin.

There are several ways to determine if a cue is straight - rolling
it on a pool table is not one of them.

Tap,tap,tap I agree with you and if I roll the shaft separately from the butt and it doesn't roll straight then its warped.To what degree is determined by the player if its going to effect his shooting.To sell a cue no matter how little the taper-roll, is still a warp.Putting a cue together and rolling it, is another story,if not properly aligned at the joint the cue could appear to be a banana but really is not, but if its just the shaft its warped.

Rolling on a pool table is fine if the cloth is clean and you avoid rolling the cue over the slate seam.Besides that the table should be the perfect way to roll a cue besides a lathe.

Rolling on top of the rail is better.
The wrap section might not be even.
Roll the cue about 3 inches below the joint slowly and look at the ferrule to see if it wobbles.

This my prefered method as well. Rolling on a table can be deceptive. :thumbup:
 
I been around a while and know how to check a cue for straightness.

I also understand tha ta cue may be straight through the center and material may have been taken off more on one side than the other. That would be the result of poor workmanship or bad tooling to me.

I personally don't mind is a butt or shaft rolls off a hair. Its wood and can move.

I just don't like to see the term used to try to explain why a cue rolls off.

Thanks for the info guys!!
 
here is a video of the run out difference between two lathes and the same shaft.

http://www.youtube.com/watch?v=EY0efdxSq7g

In the first lathe, you can see significant run out, the meter is moving 30 units (0.3mm). In the second lathe, you dont see much run out at all. If shafts are retapered, or sanded down, on a lathe like the first one, those run outs will show up on a shaft as a taper roll. Thats what I think of when I hear the term taper roll.
 
All I could see from the 1st video is a collet set that was not working properly.
The only other thing I noticed was a dial indicator getting a work over and an attempt to bend the needle and damage the indicators inner workings.
The second video showed that when it was set up correctly, the ferrule was fairly round and the dial indicator had not failed from its previous encounter with the ferrule.

Sorry, rolling can result in a 'false positive' for several reasons.

Try the search function - most of the details have been explained to death.

All cue issues aside. You can roll the same shaft on 5 different tables and get 5 different results. If the slates on a table aren't perfect you will see a false roll out.

Even half of the rail isn't accurate. Could just be a facing issue and you will get movement in the middle.

If I have to roll a cue on a table I use about 5 different methods combined then make me assessment.
