Tip issue

S

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.
 
Flat surfaces, scuff with 320. Flat being the key. If you sand the tip, do it very carefully, it's easy to fail here.
Magic eraser with denatured alcohol to clean the ferrule. DO NOT TOUCH WITH FINGERS
Prime the tip with thin superglue, immediately wipe excess. See above
Very light spray of accelerator on ferrule
Superglue gel on tip placed gently. Make sure it covers the entire surface of tip and ferrule. Move it around as little as possible.
Light pressure from tailstock
