2 things that work without a lathe:
1) Nothing. Glue it on and use. All you micro diameter guys, DTBYC.
2) Super glue. I use Loctite Ultra Gel Control. Black/Blue squeezer. That specific because this glue is not prone to cracking like standard glues or gels.
Glue tip on - CENTERED. Press tip vertically into the floor for 20 seconds or so.
Now coat top and sides with the same glue. Wipe and burnish in with folded paper towel (careful with the fingers) . A few seconds of this will dry the glue.
Have at the shaping. If you get fraying, coat with more glue.

Its not crack prone because it’s flexible, but it’s better bonding and shear strength is also reduced because of that. This is a non industrial product, they made it that way because home hobby and diy people often don’t have the equipment to ensure proper and even bond gaping (consistent pressure and truly flat surfaces…inconsistency in either of these is what makes the adhesive “crack” as you mentioned and tips fly off but what’s happening is uneven pressure causing side shear loads….
It’s at Walmart and lowes so I’ll be Frank and tell you it’s mostly marketable junk. It is by no means their most durable or best adhesive of its type.
If you want a gel with high bond, high shear and designed to bond to pain in the ass materials to bond…. Locktite 454.
If you want non gel then get the 401
For what it’s worth they don’t even have it listed or searchable on their locktite site that’s really just a Gallery of their big box store lines of products…..and none of that crap will you find in a commercial or industrial workshop besides thread locker.
if you are fraying the tip then it should either be live tooled cut, your left hand bit is dull as shit or not high enough speed or both or too fast feed or all three.
When you fluff it you’ve pulled it’s density and compactness back out. Once they are fluffed and it expands out some and also lengthens the fibers are now torn and pressing it or playing on it is never going to get it to one day be suddenly back like if should have been…when this occurs thd fix is throw away the tip it…it died on the operating table.
That’s why many many of us cuebuilders/repair
men recommend and practice press tips prior to install so they become more consistent in install and playability right out the gate in the first place
