The Straightness Checker Rollers are not a reliable way to test for straightness, in my opinion.

I just wanted to say that the Straightness Checker rollers, that you get from Amazon, for example, are not a reliable way to test for straightness, for a few reasons.

I believe that they must be perfectly aligned (in a perfectly straight line), when doing the straightness test, which is very hard to do, I think.

Also, each roller must be perfectly straight, if that makes sense.

And, the wider part of the roller is for the thick butt end, and the part that is not wide is for the thinner part, up near the joint. Some people might do that part backwards, lol.

Anyways, I am back to the feeling that rolling a cue on a pool table is the best way to test for straightness, other then an actual cue makers lathe, or other type of professional lathe, to put pool cue butts, and shafts on.

The only reason that I like the rollers though, is so that I do not have to take the cue all the way to the pool hall, which is very far away. I just believe that it is a little more complex then people think, to set up the straightness test.

I wish there were a high quality set of rollers that came with a perfectly aligned thing that they were attached to, under it, so that the test would work good, and right every time. I just do not fully trust the Rollers test anymore.

And, I believe the one from Amazon is just very cheap, and maybe there are better ones out there.

Edit: I see that a lot more companies or brands have them these days, but they are all probably very cheap, and might not offer a reliable test, unless set up perfectly.

Thanks for any thoughts.

They show wobble better than anything else.

Once you put the cue on them, they will align and be straight.
The ability to move their position can suggest where the issue is like the a-joint or the shaft joint or something else.
There is no better tool to test straightness.
You can test just the butt, just the shaft and the whole cue.
Rolling the cue on the table can’t tell you much as there might be a taper to the butt that will make you think that there is a wobble that is not really there.
Textured wrap like lizard skin may cause the cue to wobble as well when rolling on a surface.
Not needing to go to the pool hall is a big big plus

Okay, I understand. The rollers make a hair of a warp, look really bad though. If a cue only shows less then the thickness of a credit card of movement, up near the joint, when rolling it on the pool table, then that might look far worse with the rollers, and that really bugs me. Also, a cue can look pretty straight, overall, when rolling it on a pool table, both together and apart, but when you roll that same cue on the rollers, it might look far worse. A cue really must be dead straight, to really look perfectly straight, when spinning the parts on the rollers.

Why is it that when I spin the full cue on the rollers, it looks very warped, but when I roll the cue on a pool table, it appears to be pretty straight, overall? I already know the answer, lol. It is because the slightest bit of so called warp, in the cue, makes the entire cue appear to be extremely warped, when spun on those rollers.

And, this is due to a credit card (or less) thickness lift, up near the joint, on the pool cue butt.

I am just so angry. This ebay buyer is telling me that I sent him a cue with a really bad wobble, which is completely untrue. When I showed a video of how the cue rolls on a pool table, which is pretty straight, overall, without any wobble, and very slight movement in the shaft, which the video showed. I also explained the very slight movement in my description.

You need to know how to judge it and decide for yourself if it’s acceptable or not.
Additional rolling on a table is fine to get a final verdict but if you want to test absolute straightness, then this rollers are the best.

And again, I have a cue that rolls funny on the table but it’s dead straight on the rollers due to a bump in the lizard wrap

If you can separate the pieces and they roll straight on the checker, then it's possibly a joint facing or pin alignment issue. I'd have to find it, but if it's the joint face, there's a way to mate a shaft to a particular butt that minimizes that.

Try spinning the stick with both spinners on the butt end.
