Tip issue

Hello, I’m working on a customers Pechauer rogue shaft and have had 2 of Samsara tips pop off within weeks. I used Loctite on one and epoxy on the other. Any thoughts as to why they won’t stay on? Side note I’m using a Porper lathe that I’ve been using for 26 years so it’s not my first time I just haven’t had an issue like this in a long time and I don’t want to keep throwing tips at it.

Added: a picture of it. To me it looks like the glue isn't adhering to the tip...

With your extensive experience I can only imagine the adhesive is the problem. I hope others can chime in with how they solved this dilemma. Good luck.
 
Machine the face flat and smooth. I use 220 grit to sand the back of the tip flat. Check it against the face of the ferrule or pad. I use loctite gel super glue. Trim and shape as you normally do. Me personally I cut the tip down a bit, like a layer or two. That way if the person breaking is a bit squirrely there is less tip there that can be forced sideways if that makes sense. Less chance of it being sheared off is best I can describe it.

Thanks, that's basically exactly what I do.
 
I recently had the same problem, make sure everything is flat. That was my issue. The third time I put a tip on I made a jig to hold the tip in my lathe and faced it flat. I primed it with superglue and faced it again without moving the cross slide. Stayed on after that. Unfortunately I’m human and make mistakes 😳

Get rid of that fiber pad they use. They suck. Add an impact pad.
