I like to use this scraper to cut uniform coves (left).Just turn up the lathe to approximately 1,200 rpm and gently ease the cutting edge in to the proper depth. Open up the width of the cut as you go deeper to prevent the blade of the chisel from binding.Turn off the lathe to inspect the quality of the cuts often (right). ing tool to accent the candlestick pedestal by first cutting three identical slots straight into the workpiece (previous page). Then turn the slots into three beads. A bead is simply a bump. The fifth versatile lathe chisel is the 1/2"-wide roundnose scraper. Scrapers can be used to do just about every cut imaginable. In fact, if you have trouble with the shearing techniques, just use the scraper to get the profile close then add details with the parting tool. One final tip is for advanced turning. The lathe skew is primarily used by experienced turners to form perfectly smooth cylindrical shapes. This spindle turning Skew (turning between centers only) technique is tricky to master, but follow the tips in the photo caption below to turn a perfectly smooth cylinder to finish the candle stand. These tips should allow you to enjoy the successes of turning your own masterpieces in only a short while. And remember what my father taught me years ago: Never tell anyone what you're turning until it's done, that way no one will be the wiser if things change shape along the way! Have fun! PW Look closely at the height of the locked tool rest in the photo above.The tool rest must be positioned so the bevel and cutting edge of the skew is approximately halfway between the center-line (the imaginary line connecting the point of the drive spur and the point of the live ball-bearing center) and the top of the work piece. Rub the bevel first then raise the handle slowly until the bevel and the cutting edge engage the work piece at the same time.The bevel must be rubbing the wood for this shearing technique to work properly. The shaving should come off of the skew's edge about 'A" away from the heel of the skew (the back part of the skew opposite the toe) and not quite to the center of the cutting edge. TURN LIKE SCOTT Don't think you have to spend a fortune to enjoy turning.The lathe in the turning photos is the new Delta Midi-Lathe with the bed extension.The Midi-Lathe (model 46-250) retails for around $380 (including the extension bed) and offers a ^2 hp motor, 37" between centers (again with the extension bed; yes,you should buy the extension bed) and operates at six speeds ranging from 500 to 3,700 rpm. It's a great tool that's reasonably priced and with lots of utility. And now that I've told you to start turning with five specific turning tools, it wouldn't be fair not to tell you how to get them.We've made arrangements with Woodcraft (which sponsors my show) to offer the five tools I recommend as two specially priced packages, one from Sorby (pictured on the opening pages of this article) and one from Crown, at special PopWood prices.
