You know, I have seen a lot of these type spinners lately. Some are home made devices, and this one appears to be a professional tool. I just don't get it. All these little spinners appear to do is to install new tips onto shafts. Why in the world would someone buy a machine like this? If you are a casual player, it is much more economical just to fork out twenty bucks and have a pro install a new tip. If, on the other hand, you want to make a few bucks installing tips, why not just go ahead and buy a little lathe that can actually do come other work besides spin a cue shaft? Heck guys, when you get down to it, you don't really have to have a lathe to install a tip. There are all kinds of shapers that you can turn manually to get a reasonably good job. So,...am I missing something here? What is the deal with these things? Why would anybody buy one?
