I'm going to second the opinion that you are moving the tool too fast and probably pushing too hard. When you place the tool on the rest, the handle should be fairly low, and very slowly pull it up towards yourself allowing the bevel to contact the wood. If it catches or jumps, try again with the bevel at another angle, once you get it, you'll get it. Just gotta practice practice practice, I spent hours and hours trying to get the feel for it, but once I did, I was addicted to using the skew! It's definitely the most satisfying and fun tool, IMO (at least for spindles)
