10.0Operating controls

See Figures 33 and 34.

(H)Vacuum on/off switch with gauge.

(I)On/Off (headstock): Push in to stop lathe; pull out to start.

(J)Forward/reverse

When turning with face plate or vacuum chuck, make sure both set screws on the plate/chuck are tight before reversing spindle. Failure to comply may allow face plate/chuck to spin loose from spindle.

(K)Speed control dial: Always start lathe at lowest speed, with dial rotated all the way counterclockwise.

NOTE: Do not attempt to alter settings of the Variable Frequency Drive (A.C. Inverter). Use only the controls on the front of the headstock. See section 8.3 for more information.

(L)On/off (remote switch): Lift paddle on switch box to start. Push in to stop. The safety key (L1) can be removed to prevent starting. Safety key must be reinstalled for lathe to start.

The remote switch box has a magnetic backing and can be attached to any metallic surface of the lathe.

NOTE: If a power outage occurs while operating lathe, the lathe will not automatically restart once power is restored. Cycle the on/off switch in order to restart the machine.

11.0Operation

The information which follows is general in nature and not intended to be a complete course in woodturning. Nothing can replace the knowledge gained by talking with experienced woodturners or consulting books or trade magazines. Above all, simple trial and error will aid in developing proficiency in the craft.

11.1Inspection

Before operating the lathe, check that everything is in proper working order:

1.Level your machine; use the leveling feet to help reduce vibration.

2.Check bearings; adjust only if endplay exists.

3.Check belt; it should be snug but not overly tight.

4.Bed ways; keep clean, use steel wool to remove any rust spots, and apply paste wax to prevent buildup of rust and finishes.

5.Tool support; use a mill file to remove nicks and dings.

6.Spindle tapers; should be clean and free of dust and chips for proper seating of tapers.

7.Tailstock; clean and lubricate quill and locking device.

8.Lighting; proper lighting is essential to eliminate shadows and reduce eye strain.

11.2Turning Tools

If possible, select only quality, high-speed steel turning tools. High-speed steel tools hold an edge and last longer than ordinary carbon steel. As one becomes proficient in turning, a variety of specialty tools for specific applications can be acquired. The following tools provide the basics for most woodturning projects (see Figure 35):

Skews – 1-1/2" and 1" or 1-1/4", used to make finishing cuts and details.

Large Roughing Gouge – 1" to 1-1/4", used to eliminate waste wood.

Spindle Gouges – 1/4", 3/8", 1/2", used to turn beads, 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 to create square shoulders.

Large Round Nose (Domed) Scraper – 1-1/2", used to reduce ridges on interior of bowls, round edges of bowls, etc.
