If you know what you are doing it is an easy task. I have done thousands so it may seem easy to me but it really is not hard. It is well worth doing yourself.Some things are better left to the pro's who have the equipment and expertise to perform the task. I've considered getting a shaft lathe and learning how to do this myself but as often as I need a new tip, I'd be wasting materials (glue) and it would take around 3-5 years for the setup to pay for itself and I have no interest in doing tips for others. I wouldn't attempt this without a lathe. IMO, too much can go wrong. For this reason, I decided to continue to use a local cue maker for my tip replacements. Is there not someone close to you that does tips?
I have put on tips and changed them the next day because I didn't like them. You can't be doing that with a tip repair guy, especially at like $30. a pop. Or continuing to use a tip you really don't like. Besides, it's fun working on your cues.
There must be a lot of guys doing it, Chris has made a good living the last 30 or more years. I actually encourage guys to learn to do their own tip work.
