"Points" Constriction, depth, sharp vs. cnc

[nossi]

Hi there!

I was always asking myself about the construction of points in cues. Maybe you guys can be so kind and answer my questions.

1. How deep goes the point into the foream when it starts at the wrap and, particularly how deep does it go into the foream at the sharp end?

2. Whats the main difference between building a cue that has sharp points in comperison the one that`ll have the typical "round" "cnc" points. Is there really so mutch more work to do to built sharp points?

3. One maybe curious sounding detailed question: When the cue is in the status where it doesnt run conical (after you`ve putten together the foream, handle etc) and you put the taper on the cue; do the points go lower (getting shorter) by doing so?


We`ll i always asked myself these questions and had a discusstion about question 3. with a friend lately. We both were clueless... so maybe you can help me out .

Thanks in advance!

well i will try to answer some questions as best i can.
point depth is subjective and unique to each cuemaker. some feel the deeper the points the weaker the cue. some feel the deeper the point the stronger bc of the glue. i like my points to almost touch at the base.

v groove points are cut in at an angle. cnc point are cut in like an inlay. v gorrve points will shrink as the cue is turned down. cnc points will not. i dont nor will i ever do cnc points.

if you built a cue and it has a wobble the points will be off when tapered. i taper my forearm seperate from my handle and buttlseeve. then i put them together at the finished size ready for sanding. this helps the point to stay perfect.

hope this helps...

Almost anyone can do "sharp" V points. It's not difficult, and requires pretty basic machinery that is relatively inexpensive.
Sharp CNC points take a bit more thought and require some advanced computer skills, and relatively expensive equipment. Sadly, many of the people using CNCs for cues rarely get beyond fairly basic designs and methods. Most CNC inlays are around 1/8" deep. V points will be up to almost 1/2" deep at the big end and taper to 0" at the tips. They DO move when turned down, since they are angled in 3 directions.
