It's probably worth a phone call first to ask the cue maker. The person in our area who does ferrules and tips does not mind if you bring tips with you as that saves his stock. I have found out that bringing a large mountain dew, $ 10.00 for each install and a little larger amount offered instead of his asking price usually gets him to respond quickly. I usually take more than one shaft with me as if he does only one tip for a person, he asks for $ 15.00 and then of course, if he sells the tip, it's more. He displays the cost of install with different brands of tips very clearly when you walk in his place. Of course, and I do agree with him, if he sells you the tip and does the install and the tip comes off, he does not charge anything to replace it or re do the work. If you bring in a different type of tip and more importantly, ferrules that are of certain types, he will do the work, check the tip out that it's secure when you leave, but, if it falls off, you will pay for another trip since he did not sell you the tip. I think that's fair. I know once at a pool tournament years ago, the person who was doing repair and tip work tried 7 different elk master tips before putting some other tip on. All the elk master tips he had were so spongy, poor guy had a nightmare. Just to say, I would probably check the prices and his thoughts before I would just walk in and lay certain tips down as depending upon the tip and the ferrule material, he may on rare occasions want nothing to do with it. Twenty Five years ago, I found out that a simple triangle tip on a Meucci Ferrule would not stick unless I used a apoxy mix glue. Standard tweeten glue would not hold. A real Pain in the butt, glad someone took up the hobby !!!
