Hi, I have an OB Classic Pro shaft (11.75) with the stock Everest tip. I want to shape the tip but I'm not really sure how to go about it. My friend has this silver hourglass looking thing with one side marked scuff, the other shape, and there's a bunch of needles when you screw it apart. Can I use that?, and how do I use it (spare no detail). I watched one guy put it on the floor and turn his cue over while holding the shaper between his feet. Also since I have an 11.75 mm tip, do I need to find a nickel radius or dime radius shaper.
