oops! I left some words out here. Sorry. The less the cue ball squirts the more power being used to spin the ball. This is what I meant to say. The force or power is absorbed three ways. So much goes to squirt, so much goes to the cue ball going straight, and so much goes to spin. The less force...

Flexible. The more flexible to a point, the less squirt. Once you reduce the max squirt by making a shaft flexible then you start to loose power in the cue.

Look at it this way. If a train was going ten miles an hour and hit a guy on a motorcycle it would knock the motorcycle over and probably propel it a few feet. On the other hand if the train was going 80 miles an hour it would propel that motorcycle a long way. When the shaft is coming at the...

a more flexible shaft bends out of the way allowing the cue ball to go straighter in the forward position. A stiffer shaft does not bend out of the way allowing the sideways force to squirt the ball. This is one shaft characteristic example that makes a huge difference. The less the cue ball...

There are a lot of other variables that are missing here. And there important because it can go both ways kind of. You are not more accurate with where you are trying to contact the cue ball with the small tip in the since that the smaller tip will hit more to the out side of center. Hitting...

Well I truly value your input. But what your asking will take a ton of my time that I don't have. I will not get paid for this time and I'm loosing money in the shop. Further more I have customers with cues on order that want to see progress on their cues. I can't spend all this time typing and...

Various speed in robot tests I have read some of the posts here and I want to clear something up. We have had the robot for nearly a year. Before the robot we had other testing jigs but I must admit the other testing equipment was no where as sophisticated or as accurate as this machine. The...

Some test result info! Ok I can see that I am going to have to list some results so they can be commented on or discussed. So I need some specific questions or tests that you want the results for. As I stated earlier we spent hundreds of hours testing what seem like everything. From different...

Question #1 Answer: I have not posted all the results yet. The results are actually pages and pages for different senerios. Meaning a European taper with a soft tip and a nickle radius shape vs. a European taper with a hard tip and a nickle shape, and a European taper with a hard tip and a dime...

Ya but don't forget to factor in a soft tip vs. a hard tip into the equation. When a soft tip with a nickel radius makes contact with the cue ball it compresses and forms to the cue ball thus stays in contact with the cue ball longer with increased friction which also carries the cub ball...

Well, I have the results now. So I guess as for when I would say now. I would like this to be a good resourceful thread to help others and used as a reference. I have set this thread up just to do that. I am going to try to spend quite a bit of time working on this thread with great hopes that...

First cues ever built From the research I have done I learned that the first cues ever built had little thought in the design and had little engineering to say the least. They did not do any high speed photography, robotic testing, trial and error in performance and so forth. They seemed to...

Chalk and friction We need to take a look at chalk and friction between the cue tip and ball and what effects this has on the outcome.

Tip hardness and shape We will also need to take a look at tip hardness and the shape or radius and what effects it produces. Some believe a nickle radius is better than a dime and vise versa. One thing I want to mention is the difference in contact points with the different radius and also...

Pics of shaft styles Here are a few pics. It is difficult for the actual shaft taper to photograph. Also here are just a few different methods for changing shaft stiffness and at different locations. This was also used to experiment with different pivot points. Other methods were also used and...

Various shafts I want to discuss the various shaft styles and tapers and some myths that go along with them. Some believe that a stiffer shaft has less cue-ball deflection and some believe that they produce more. First you have to determine what is causing the shaft to be stiff. Is it the...

Testing and Study Complete! First let me start by apologizing for not being here to answer all the questions and posts. I need the help of all you AZers out there. A lot of you have great perspectives and questions. I would like to talk to some of you on the phone. I just spent 12 to 16 hours...

As some of you know, we are getting close to completion on our study and experiments regarding Low Deflection Shafts. Countless hours of robotic testing and trial and error have shed new light on the subject. Some myths that have puzzled us all for years have now been resolved and can be proven...

Cue has been sold!!! Cue SOLD today 6/22/2012 for $1200 plus shipping! Thanks to all who inquired. I knew this cue was going to sell fast. The new buyer does not have to wait a year and a half now to get a Barioni Cue.

Pics of cue Here are some pics of the cue. There is a lot of fancy ring work that is made up but not yet installed on the cue. Cue has already been SOLD!!
