I've always used triangle tips, have a lathe, have never had a problem putting them on, never had one fall off on me.
I recently bought some ultraskins to give them a try. Don't know if there's a different method of installing but I'm not having the success I always have with the triangles.
Here's my current process.
I rough the tip on sand paper to flatten it, score the flattened area with a razor. Also score the cleaned up surface on the shaft. Put gel super glue on the tip, rub it around on the shaft surface so I have complete coverage, position it and hold it tightly in place for a count of 30 or so. Then I let it sit for a 5 minutes or so before trimming.
Do the same with the ultraskin and it tends to fall off either when letting off the pressure or when trimming.
Anybody see anything I'm doing wrong for a layered tip?
Thanks for any advice.
