G Core shaft

Anyone have any trouble putting a tip on a g core shaft? I’ve had 2 pop off. After the first one popped I switched glue(to loctite proffessional) and replaced the .030 fiber tip pad . Got a text today and it came off again. Been doing this more than 20 years and I can only remember 1 other tip coming off.
 
We've got 3 of them. Have put various Ultraskins on them and never had one come off. I don't play with them much anymore though. I use Loctite also. While not a professional cue guy, I do have a cue lathe and have probably put 75 or so tips on, mostly Ultraskins, or lately some Triangles, and have only one come off. Turned out the ferrule was loose and I didn't catch it.
Maybe they are miscuing a lot or possibly not taking care of the cue and it is falling down on a concrete floor. Our Monday night league with 48 players and concrete floors, I hear cues fall and slap the floor 2 or 3 times every night. My teammate knocked mine down one night and took a bit to get the embedded grit out of the shaft. I don't stand mine next to hers anymore.
 
wait 2 days before shaping or use

Hope that's not for Triangles, or Ultraskins for that matter. I'm down on my table shooting a few shots with them in an hr or so. I don't do draw or break shots till the next day though. May have to change my ways.
 
It’s an Ultraskin ivory…. I’ll check the ferrule closely when I get it back tonight, maybe it’s loose.
 
The one I had come off because of a loose ferrule, was an older inexpensive cue with a non capped ferrule. If I remember, my Gcores are basically a capped version, I think, but it's been awhile.
 
The first failure was between the tip and the pad. I replaced the pad thinking it may have been the problem and was getting thin anyway. I’ll get the shaft tonight to see where it failed this time.
 
I've done a lot of tips on G-cores and never had one pop off.

I have gotten a bad batch of tips though, where the base layer kind of disinigrated after installation and would neatly peel off after 3-4 days of playing.

I've also had it where I've gotten lazy with my facing of the ferrule, didn't lock down my carriage or had my toolpost loose and made a slight convex shape in the ferrule, and got bad glue ups.

If I have a problem that persists like this, I generally take it back to square one. Fresh tip, fresh glue, fresh ferrule if the old one is at all in question. Face the ferrule, do not sand it, do not score it, it's never needed. Then sand your tip, don't be lazy and use the workbench, use a known flat surface. I use my machinist vice, it's good enough. I like to pre-soak the tip with thin CA at this point, wipe off excess, blow dry. Then grab your medium or thick CA, small glob on the tip, mate it to the ferrule and smear it around once, then press that bitch on tight and wipe off the excess glue.

Now, this point is where I do a something a little different and noticed good results. Take a can of aerosol CA activator and spray the tip / ferrule liberally. You want it to soak in a bit and really set the glue. I started doing this after I had a tip pop off once while I was shaving it, and the glue in the very center was still somewhat wet, and I could tell the crust from the flash had broken, probably from when I turned it in the lathe after gluing. So, the activator just makes damn sure that glue is cured before you hit it with any tools or sandpaper. I've noticed no problems, been doing it for about 12 tips now on different peoples cues.
