1411.2 Turning ToolsIf possible, select only quality, high-speed steelturning tools. High-speed steel tools hold an edgeand last longer than ordinary carbon steel. As onebecomes proficient in turning, a variety of specialtytools for specific applications can be acquired. Thefollowing tools provide the basics for mostwoodturning projects (see Figure 18):Figure 18Basic Turning ToolsSkews – 1-1/2" and 1" or 1-1/4", used to makefinishing cuts and details.Large Roughing Gouge – 1" to 1-1/4", used toeliminate waste wood.Spindle Gouges – 1/4", 3/8", 1/2", used to turnbeads, coves and other details.Deep Fluted Bowl Gouge – 1/4", 3/8" and 1/2",used for turning bowls & plates.Square Scraper (Bedan) – 3/8” or 1/2", used tocreate square shoulders.Large Round Nose (Domed) Scraper – 1-1/2",used to reduce ridges on interior of bowls, roundedges of bowls, etc.Parting Tool - 1/8", used for scraping, making acut-off, or to set diameters for sizing.For safety and best performance, keep tools sharp.If a tool stops cutting or requires excessivepressure to make a cut, it needs to be sharpened.A number of brand name sharpening jigs andfixtures are available; however, a woodturnershould learn to sharpen tools freehand.For best results, use a slow speed grinder (1800rpm) fitted with a 60-grit aluminum oxide wheel (forshaping) and a 100-grit alum. oxide wheel (for finalsharpening and touchup). The grinder should belocated near your lathe and at a comfortableheight. A diamond dresser will keep the wheelstrue and eliminate glazing.Never allow the tool to rest in one place on thewheel, keep it moving and use a light touch.Carbon steel tools can overheat easily and shouldbe cooled frequently. If the edge turns blue, it haslost its temper and should be ground past the bluearea. High-speed steel tools are not as likely tooverheat, but can be damaged if allowed to get redhot. High-speed steel tools should not bequenched for cooling. Honing with a diamond lapor slipstone will save trips to the grinder and keepthe edge fresh.11.3 Spindle TurningSpindle turning takes place between the centers ofthe lathe. It requires a spur or drive center in theheadstock, and a live or dead center in thetailstock. A cup center rather than a cone center inthe tailstock will often reduce the risk of splitting thestock.Figure 19 shows the basic profile shapes in spindleturning.Figure 1911.3.1 Stock SelectionStock for spindles should be straight grained andfree of checks, cracks, knots and other defects. Itshould be cut 1/8" to 1/4" larger than the finisheddiameter and may require additional length so theends can be removed later. Larger stock shouldhave the corners removed to produce an octagonmaking the piece easier to rough down to acylinder.1. With a combination square, or plastic centerfinder for round stock, locate and mark centeron each end of the workpiece. Accuracy is notcritical on full rounds but extremely importanton stock where square sections are to remain.
