Required Personal Protective Equipment (PPE)

All PPE must be worn at ALL times when operating the lathe:

  • Full Face Shield: ANSI-approved face shield required—safety glasses alone are NOT sufficient. Wood chunks and chips can fly at high velocity and strike your face.
  • Dust Mask or Respirator: Minimum N95 rating. OSHA links wood dust exposure to respiratory issues and other health problems.
  • Hearing Protection: Earplugs or earmuffs with minimum NRR 32 dB protection for extended use.
  • Closed-Toe Shoes: Steel-toe safety footwear recommended.

Critical Safety Rules

Failure to follow these rules can result in serious injury or death:

  1. NO loose clothing, jewelry, or gloves. Remove neckties, bracelets, watches, rings, and secure or remove any dangling items. Loose items can be caught by rotating parts and pull you into the machine.
  2. Tie back long hair. Hair can be caught by the rotating workpiece with devastating consequences.
  3. Never leave the lathe running unattended. Always turn off the lathe before walking away, even briefly.
  4. Stand to the SIDE when starting the lathe. Never stand directly in front of or behind the workpiece—this is the “red zone” or “firing zone” where pieces are most likely to fly if they come loose.
  5. Always rotate the workpiece by hand BEFORE turning on power. This confirms clearance from the tool rest and bed.
  6. DO NOT operate with any guard disabled, damaged, or removed.
  7. Inspect wood carefully before mounting. Never use wood with checks, splits, cracks, loose knots, or foreign objects embedded.
  8. Ensure the workpiece is securely mounted before turning on the lathe.

Speed Selection: Critical Safety Considerations

⚠️ Selecting the wrong speed can cause the workpiece to fail catastrophically, resulting in serious injury.

Golden Rules for Speed Selection

  • ALWAYS check the speed setting BEFORE turning on the lathe. The previous user may have left it at high speed.
  • Larger diameter = SLOWER speed. Big workpieces must turn at low RPM to stay safe.
  • Always START at the lowest speed for any new or rough workpiece until it is balanced.
  • If the lathe vibrates or shakes, STOP immediately and reduce speed or check your workpiece mounting.
  • Gradually increase speed only after the piece is running smoothly and balanced.

Recommended Speed Guidelines by Workpiece Diameter

Workpiece DiameterRoughing SpeedFinishing Speed
Under 2″1,000 – 1,500 RPM2,500 – 3,550 RPM
2″ – 4″800 – 1,200 RPM1,800 – 2,500 RPM
4″ – 6″600 – 1,000 RPM1,200 – 1,800 RPM
6″ – 8″400 – 800 RPM800 – 1,200 RPM
8″ – 10″300 – 600 RPM600 – 900 RPM
10″ – 14″250 – 400 RPM400 – 600 RPM

Note: These are general guidelines. Factors like wood species (hardwood vs. softwood), workpiece balance, and the presence of defects may require even slower speeds.

How to Change Speed

  1. Turn off the lathe completely before making significant speed adjustments.
  2. Use the electronic variable speed control dial to adjust RPM—the digital readout will display the current speed setting.
  3. For rough, unbalanced, or large workpieces, always start at the minimum speed (250 RPM).
  4. Stand to the side and turn on the lathe briefly to check for vibration.
  5. If stable, gradually increase speed while monitoring for wobble or vibration.
  6. If any vibration occurs, immediately reduce speed and investigate the cause.

Changing Tool Heads (Drive Center, Live Center, and Faceplate)

⚠️ Never attempt to change tool heads while the lathe is running. Always unplug the lathe when installing or removing centers and faceplates.

Installing/Removing the Spur Center (Drive Center)

The spur center mounts in the headstock spindle and drives the workpiece with its pointed center and spurs that grip into the wood.

  1. Ensure the lathe is OFF and UNPLUGGED.
  2. To Install: Align the Morse taper (#2) of the spur center with the spindle bore. Insert and push firmly—give a light tap with a wooden mallet if needed to seat securely.
  3. To Remove: Use the provided knockout rod. Insert it through the hollow headstock spindle from the outboard side and tap to release the center.
  4. Verify secure seating before operating—a loose center can cause dangerous workpiece ejection.

Installing/Removing the Live Center (Tailstock)

The live center supports the opposite end of spindle workpieces and rotates freely with the work.

  1. Ensure the lathe is OFF and UNPLUGGED.
  2. Retract the tailstock quill using the handwheel.
  3. To Install: Insert the Morse taper into the tailstock quill bore and push to seat.
  4. To Remove: Fully retract the quill—this action automatically ejects the center via the internal knockout mechanism.
  5. Check alignment: The spur center and live center should meet exactly on center for proper spindle turning.

Installing/Removing the Faceplate

The faceplate is used for bowl turning and face work where the tailstock cannot support the piece.

  1. Ensure the lathe is OFF and UNPLUGGED.
  2. To Install: Thread the faceplate onto the spindle (1″ x 8 TPI). Hand-tighten securely.
  3. To Remove: Use the spindle lock (if equipped) or hold the spindle while unscrewing counter-clockwise. Be aware that during use, the faceplate naturally tightens from rotation.
  4. Mount workpiece to faceplate using appropriate screws before attaching to the lathe—never attach an empty faceplate and then try to mount wood.

Basic Operating Procedure

Pre-Operation Checklist

  • ☐ Wearing full face shield, dust mask, hearing protection
  • ☐ No loose clothing, jewelry, or dangling items
  • ☐ Long hair tied back securely
  • ☐ Workpiece inspected—no cracks, knots, splits, or defects
  • ☐ Workpiece securely mounted
  • ☐ Tool rest positioned close to workpiece (approximately ⅛” gap)
  • ☐ Tool rest locked securely
  • ☐ Workpiece rotated by hand—clears tool rest and bed
  • ☐ Speed set appropriately for workpiece size (start LOW)
  • ☐ Work area clear of debris and other people

Operating Steps

  1. Mount your workpiece between centers (spindle work) or on the faceplate (bowl work).
  2. Adjust the tool rest parallel to the workpiece and as close as possible without touching—about ⅛” gap. Lock it in position.
  3. Rotate the workpiece by hand one full revolution to verify clearance.
  4. Set the speed to the lowest appropriate RPM using the variable speed dial.
  5. Stand to the side (not in line with the workpiece) and turn on the lathe.
  6. Observe for vibration or wobble. If present, stop immediately and troubleshoot.
  7. Rest your turning tool on the tool rest first, then slowly advance it into the spinning wood.
  8. Use controlled, smooth motions. Let the cutting edge do the work—never force the tool.
  9. Periodically stop to reposition the tool rest as material is removed.
  10. Remove the tool rest before sanding. Hold sandpaper against the lower portion of the spinning workpiece.
  11. Turn off the lathe when finished and wait for complete stop before leaving.

Common Wood Turning Tools

  • Roughing Gouge: Used first to knock corners off square stock and create a cylinder.
  • Spindle Gouge: For creating coves, beads, and details on spindle work.
  • Bowl Gouge: Deeper flute for hollowing bowls and working on facework.
  • Skew Chisel: For smoothing and creating precise cuts (advanced tool).
  • Parting Tool: Thin tool for cutting workpieces free and creating tenons.
  • Scraper: For final smoothing and detail work.

Important: Keep all tools sharp. Dull tools are more dangerous than sharp ones—they require more force and are more likely to catch.

Maintenance

  • Before each use: Clean the lathe bed and ways of dust and debris. Check all locking mechanisms.
  • After each use: Clean wood chips and shavings from all surfaces. Sweep surrounding area (wood chips are a fire hazard).
  • Regularly: Apply light lubricant (WD-40 or machine oil) to the lathe bed ways for smooth tailstock and tool rest movement.
  • Periodically: Check belt tension and condition. Inspect drive centers for wear. Verify alignment of headstock and tailstock.

Makerspace Etiquette

  • Clean up thoroughly after use—leave the lathe cleaner than you found it.
  • Report any issues immediately to board@reforge.io or post in the Slack channel.
  • Do not adjust settings or make repairs without authorization.
  • Store turning tools in the holders located on either end of the lathe. Return all tools to these designated holders after use—do not leave tools on the lathe bed, bench, or elsewhere.
  • Connect dust collection when available to keep the workspace clean.
