Vaughn.....two things......Your skew must be sharp, sharp, sharp. I hone mine with a fine diamond hone after sharpening. Then you ride the bevel. If the bevel is too long it can be a booger to control. The length of the bevel should be approximately 1.5 times the thickness of the steel of the skew. Any longer and it get's difficult to control because a slight change in the rear hand and handle causes it to bite into the material
2nd.....light cuts....and if necessary.....use it as a scraper. The thing I like about acrylics, the skew presented almost flat makes a wonderful scraper and I'll often use it that way to refine the round shape as in the rose b/s. I use the skew as a skew to make fine detail cuts and to remove bulk materials. I can use it to refine shape but in this case when I'm just make really, really fine changes in form to make the b/s more round, I'll use it in the scraping mode and make really, really fine, gentle scraping motions.
I am really beginning to like my skew. I've got new brand new Lacer skews that I got 3 weeks ago that I haven't sharpened or used yet. I had these acrylics that are so quick and easy I wanted to get them done and then tear down the lathe and finish the shop. In a couple of months, God and my wife willing I hope to be installing a new lathe, Oneida DC and a Steel City B/S.
