wobble?

[jayman]

If you turn a dowell on a high quality lathe, and make any number of cuts and angles gouges tapers etc.., even till it looks like furniture or a bob renis cue, whith any number of tapers,fancy curves you put on this dowell, will it not? (barring warpage or damage), still roll without a wobble on a perfectly flat surface

Thanks, Jayman.

If it did, ALL shafts would wobble. LOL
Shafts have at least 3 tapers unless you have a conical shaft from tip to joint.
The distance from center axis should be equal on two sides on all parts of the shaft unless hand sanded or cut too fast.
Of course unless the wood moved, shrunk or expanded.

Joey you saved me from a heart attack!

I was going nuts having to listen to ol' "its just taper roll" line for selling warped or less than perfect cues. and after explaining it, ( not so well as as you did I admit) It still drew vehement argument???? at least some one on this earth gets it!

Thanks Jayman.

I have owned Qs that roll as straight as the eye can decern....BUT on certain days they will seem to develope a very slight wobble. A day or two (or weather change), latter & back to straight again. I still can't figure it out...JER

Same here.
On very dry days here in SoCal wood moves a ton.
When the humidity settles, the good ones go back to being straight.

Is it "taper roll" ?

No, it's wood moving.
Mostly following it's grain.
I have a theory that wood always has a stiffer side and a weaker side.
The stiffer side would push the weaker side when the humidity gets really dry.
Wood shinks too on dry days, and I think the weaker side shinks just a little more.
In fact if you have a shaft with a real high grain count, you will notice that oftentimes it will warp toward the side of the shaft where the rings aren't as tight ( the weaker side ) before it really finally settles ( and it can still move on dry days ). So in a perfect world, I would love all shafts to have the same ring count on both sides of the center.
just my theory worth 1 cent

What's really crucial, IMO is that the front of the shaft and ferrule stay on the table at all times when a shaft/ cue is rolled. A very slight amount of taper variance (under approximately 1/16" ) or "wobble" is within normal limits of a pool cue shaft made of hard maple.

Wobble

Rolaine, a source of shaft wood has an statement about wood moving, stressing the importance of the straight grain in the shaft. They claim is has to do with the fact that different parts of the tree handle moisture differently. If you have a straight grain running the entire length of the shaft, then that comes from the same part of that tree and should expand and contract the same. Don't know, but seems to make sense. Not sure what some people call taper roll, but think about this. A shaft has a spline, IE, it will bend more in one direction than another. Usually across the grain or with the grain. Now if the taper of your cue pushes the tip of the shaft into the table when you roll it,(true on just about every cue. If you extend the taper of the butt, it doesn't met at the tip.) it may look like the shaft is acting differently when you roll it. Has to be pretty good spline to do this. Try rolling the cue with tip on the rail, the elevated joint should run true. I've also seen shafts where the cuemaker couldn't completely turn down a wobble and the shaft wasn't round,(has a low side) in the middle of the shaft. That will give the appearance of a wobble when you roll the cue. As the low side of the shaft shows more light under it than the high side.
Just my two cents.

This thread reminds me of the book Shepherd of the Hills in which there was an old handmade chair at the Post Office which the locals used to forecast the weather, depending on what shape it contorted itself into on a particular day.

Smorg, wake up that horse

OK, one more time

pleazzzzzzzzzzeeeeeeeee stop rolling cues on tables.
it does not tell you if they are straight

Sight down the cue like a rifle
if you can't see a problem, there is no problem

Thank you Dale. My father taught me to do this when I was very young (just look at my avatar), and I am still surprised when people don't do this when they want to check out whether a cue is straight. It got to a point where I thought I was being looked at funny when I would do this rather than roll it.
