tip radius of professionals

radius of curvature

Okay, how about calling it radius of curvature or anything else you wanna call it. You know what I am talking about. Buzz Killington hahahah.:smile:
Anyhoo, I appreciate the schooling but it fails to address the question asked in this thread. I am curious about the trends of pros and their tip shapes or if there are any? I can't seem to find much info on it. Thanx for all your responses.:)
 
Interesting about JA. Wonder how you could do that consistently. As far as precise shaping goes, it seems like like it would be important given the fact that if one side of the tip is different than the other, then your Cue stick center aim point would be different when trying to using english depending on how you hold the cue. Snooker players would certainly experience this less(due to the flat butt) but any twisting motion should certainly bring about a similar unknown change in needed aim.(unless theres no cb deflecion). this makin' any sense?
 
I've known quite a few players (and heard that some pros do this--maybe Jim Rempe?) that put a small dot on the edge of the tip or on the ferule itself to ensure they use the exact same spot on the tip every time.

He told me when doing a clinic down here that he likes it flat on the tip and then flat again at the edge for better contact on cueing the side of the ball. Instead of a round edge striking the round edge of the cue ball you have a flat edge hitting the rounded edge of the cue ball. Made perfect sense to me. Like so:

Wow...never seen that before...I guess you could do this by using a dime bevel and finishing with a nickel bevel to flatten the face of the tip. Probably lots of ways to do it, but routine chalking and play would quickly knock this out of wack. Must be a bear to keep up with.

I am sure it is easy for someone who ownes a lathe. Touch a spinning tip with sandpaper and it changes shape real fast.

I am actually going to try it on one of my 234569 shafts, but I freehand it.

Lathe, or use a tip tapper perhaps, after you radius shape it.

I prefer a penny on my thinner shafts (12.25). For 12.75 or 13 or more, I prefer a nickel.
 
Just an fyi, I was wondering what the name of the 3-dimensional spherical analogue to the 2-dimensional circular 'arc' is. It's a 'spherical cap'. From wikipedia:

I don't know about the pros, but the fact is that the smaller the radius of the tip's spherical cap surface, the further out on the cue ball you can go without miscuing.

JA's variable radius strategy, while difficult to create and maintain, would seem to be a valid approach. I'm a little skeptical that it's geometrically accurate, however.

Hittin a pool ball it isnt a hydraulic system, l think the margin for error is more akin to deck-building. Close is good enough.

I doubt the levelled tip really provides any measureable (and non-mental) performance differenc, but I am sureassheeat gonna try it!
 
This is incorrect information. There is no significant difference in applied spin between a nickel or dime shaped tip. The size of the contact patch, between CB and tip does not change, regardless of tip size or shape. It is purely personal preference.

; a dime can't juice the CB like a nickel. I was told years ago that a nickel bevel was ideal for the curvature of a CB, a dime is too much and loses energy as it swipes/slips past the contact point. A nickel bevel directs more force into the contact point.

spherical cap shape

Interesting discussion so far. I was under the impression that juicing the CB is easier with dime. Possibly because it focuses more core energy from the cue? Also, with a 3d dime spherical cap shape :) you don't have to move the Cue stick center as much of off the CB center to apply english. This may just be "mentally easier" for some.
