Need some help here. Let me start by saying I keep my tips in a humidor until installation. I use a Mid Size Cuesmith lathe. Only use new Lenox Bi Metal blades for each install. Lately, my layered tips powder (for lack of a better term) when I shape them. Have any of you more experienced installers had this happen? If so, how did you try to correct this. Thanks for any help or insight you can provide. I won’t mention any manufacturer because I’ve had it happen with more than one tip provider.
