Your thoughts on taper roll?

[ElCorazonFrio]

I think you are purposely taking this to levels of ridiculousness to try to prove me wrong.

I did not for it mean to come across that way at all. What makes this difficult is trying to explain from a keyboard. I can take a piece of tubing and put it in my lathe. The hole up the center can be dead straight but when I take an O.D. surface cut the bit may not remove material from the entire surface on the outside. Even though the I.D. and O.D. are not perfectly concentric with each other I would hesitate saying it is not straight.

No offense taken. Let's go down a different path:

You have this tube that you have removed material from in a small portion of the circumference in one part.

Now, let's imagine that you are going to attache one end of that tube to a cylinder and you are going to run the pipe through a device that will adjust to hold the tube on the circumference. Now, this device is fixed and the adjustment that it makes will always be about a single point that never moves...basically it is an expanding and contracting device which will always have the center of whatever geometry it needs to conform to in the same place.

Now the piston pushes the back of the tube straight toward the center of the holding device. Is the other end of the tube going to travel in a straight line?

I really hope the answer is obvious to you, but in case it isn't, the answer is 'No'.

Thus, I submit that the tube is not straight in the way we are using it.

Shafts are not precision machined items though (past a certain point), we're not trying to measure how straight things are that need total precision. For example I would not want my car cylinder to be as "straight" as that candlestick LOL. But that candle stick is still "straight" if you asked if it was bent or straight.

If the tip or joint do not wobble around, that would be a straight shaft, changes in diameter does not make it less straight as a shaft. If I was making a straight part that I wanted to be parallel to a laser for a mile distance then we'd have a different definition of what "straight" is. For a shaft, not so much.

Alright this has been a fun exercise in semantics. Thanks for the replies.

When I am selling the shaft has a taper roll.

When I am buying the shaft is warped.

That reminds me of an old saying about the grade of a collectible coin. When selling, it is AU-50. When buying, it is VF-30.

I just recently received a new sneaky pete from Schmelke. I got them to fit an OB pro+ to it. I am very happy with my purchase and the cue shoots great.

I have noticed that if I roll the cue on the table, a sliver of light comes through below the shaft every half roll. The tip does not leave the table surface. When you view the cue rolling from above, it doesn't appear to have that kind of 'oscillating' roll you notice when cues are out of whack.

Do any of you pay any attention to this? Do you try and find a way to correct this now or do you wait for a turning point where it does start to bother you? I have never really let it bother me, and have certainly had it on previous cues. Just not sure where taper roll turns into "your cue is not straight bud"....

i do pay attention and notice taper roll when examining a cue, but it's a non issue to me.

In all actuality, shafts are waaaaaaay to precise for the job they do...from an engineering/manufacturing perspective.

By-the-by, I missed your ridiculous candlestick photos earlier...I would in no way, shape or form claim that either of those candlestick holders are straight. Look it up in a dictionary, I think you are confused as to what straight means.

Ken_4fun said is best..........could very well be the very same shaft but different descriptions when you are selling vs. buying.........any cue-makers out there wanna chime in?

Here you go http://dictionary.reference.com/browse/straight?s=t

At least a handful definitions having to do with objects would describe a shaft or a candlestick. If you can have a "straight path" which is easily not as even as a shaft along the edges, you can have a straight shaft without a perfectly even circumference.

Just to see what others though, I did a web search on "straight stick", this is one of the top hits

If that's "straight" then a shaft that does not wobble at the tip or joint must be straight.

I'll ask my 9 yr old at home to see what she thinks straight is, we'll get it sorted out I'm sure sooner or later.

Here are some "straight leg" jeans, but they are bumpy, how can they be called "straight"???

Do we need more examples of what something straight is?

As I said, being even and smooth does not make an object "straight" nor is being bumpy make an object NOT straight.

Okay, trolly. You win. Every bumpy, crooked, bent object in the world is straight if you deem it so.

 

[Rain-Man]

Just fix the taper roll. It'll take all of 2 minutes..

 

[gunzby]

Here's what I do to prevent taper roll. I never roll a cue on the table. This way every cue I use is absolutely perfectly straight. I don't even roll cues I pull off the wall. It's my one pool superstition

NOT bent, then it would not be straight. I think you did not read what I wrote very well. And a guy with 14 posts is calling someone with a few 1,000 a troll? You asked if I knew what straight was and to look it up, I did. Showed you the results of my research which you guided me to do.

I've read AZB for years, since about the time you started on here. Your replies here are trolling because you deliberately took things out of context to try to make a guy 'with 14 posts' look like a guy with no knowledge.

I've read a lot of your posts...enough to know to skip most of them. I seldom see you give good information, mostly you want to be contrary for the sake of being contrary.

best, D.
