youre gonna get 800 different answers. here all you need to know. climate control and proper storage. if you leave a cue leaning against a wall for a year it wont stay straight. hanging is the best way. nothing is more true then gravity. laying flat would be my second guess. also maybe a vaccum sealed case like its george or fellini keeps the moisture out.
Das ezacly right.
As long as you keep it in your case and don't bake it, freeze it, or drown it, you are good to go. Also, keeping it clean will help in more ways than one.
If you have a locker at the pool hall, that is the ideal place.
Also, there was something about temperature change. That is the primary enemy, especially with ivory. Natural materials shrink and swell according to it's climate.
If you have it in your car in the winter time, and your cue is frozen, make sure you thaw it out. It could be bad if you don't. Also if you have it in your car in the summer time, it can loosen up the glues that are in the cue.
Moisture escaping from wood is done in a controlled manner. If moisture escapes too fast, the wood will be unhappy and frown on you. Also, there are materials in a cue that are natural and un-natural and they act differently to one another. Actually, phenolic rings are used to hold a cue together and keep it from splitting which is a rarity.
Ivory is your biggest concern when it comes to dealing with hot / cold. It likes to be kept in a normal atmosphere where it doesn't get too dry. It can get brittle and crack. Wood is more resilient. There are some woods that are less stable than others. Burled wood and snake wood are two prime examples. They must be cored out if used for a front.
If you store it properly under room temperature, you cue will last longer than you will live, real the question is, how will your children treat it?
Hope you got the answer you were looking for.......
