It would be an older Meucci that still has a tip I installed over 25 years ago firmly attached.
I recognized that you have done cue repairs for almost 20 years. I've been using Tweeten's for over 40.
In any case, this thread is not about what glue a cue mechanic should use -- it's about what a do-it-yourselfer should use. Presumably the guy has no lathe and is going to make a mess his first few times out and for that I still believe he's best off using Tweeten's, which he can effectively clean up afterwards.
BTW, this morning I recalled that I had some Elmer's rubber cement in the house and I looked at a dab of rubber cement next to a dab of Tweeten's. They are totally different in viscosity, color, and smell and I seriously doubt you could use the rubber cement for a tip install.
Also this morning, I sent an email to Tweeten up in Chicago and mentioned your claims about their product's similarity to a rubber cement formulation, its adhesion properties, and viable applications vis a vis various ferrule materials. I'll let you know when/if they respond.
