I replace 15 - 20 tips per week. As long as I prime the tip and the ferrule with thin CA before I apply the Loctite Ultra Gel Control, I have excellent results. Surface preparation has been the key for me. No pop offs in months. Every cue maker that I currently associate with on a regular basis uses this. I've tried 401, 411, & 454. Those glues work well, but in my opinion, the cost to effectiveness is no better than the Ultra Gel Control. I perform a pop off test to every tip that leaves my shop by laterally hitting the tip about 50 times against the floor. Not hard enough to break the ferrule or wood, but fairly hard. Rarely does the tip pop off with this test. (PM me for how I keep from losing the tip in case it does pop off.) I will also add that adequate clamping pressure is also very important, as well as the age of the glue once it has been opened. If the bottle has been opened over 30 days, it goes in the trash. Finally the glue must not be allowed to get cold or excessively warm for it to maintain it's effectiveness.
This topic has been discussed before, and I'm basically just sharing my summary of what I've learned from this forum. Nothing new here. :smile:
