Induction Required

This equipment requires an induction prior to use. For your own safety and to avoid damage to the equipment do not attempt to use it until you have been inducted.

The lathe belongs to Anton, is in G10, and is free for hackspace members to use. You can requests inductions on the Google Group.

This is a Clarke CWL20RV Lathe (manual).

The headstock has 1“ x 8 tpi thread for a chuck. Both headstock and tailstock are MT 2.

Please follow sensible safety rules:

  • wear eye protection
  • don't wear long dangly things (clothes, hair, jewellery)
  • make sure workpiece is secure and can rotate freely before switching on
  • if you use hands on the rotating workpiece (sanding or polishing), do so on the opposite side of the work, away from the toolrest, to avoid getting fingers trapped.

Unique Quirks

  1. The lathe must be started and stopped on its lowest speed. You can only change the speed while it is running so it is important to stop it in its lowest speed otherwise you won't be able to start it on its lowest speed. Starting on the lowest speed puts less strain on the capacitor which starts the motor and reduces the chances of it stalling. The capacitor has died once and was replaced with one with half the capacitance. If it does stall, a quick spin of the head and it should start moving!
  2. The only other thing that makes this lathe different from most is the ability to rotate the headstock to allow you to turn larger blanks. The head rotates which allows to spin huge pieces. If you do this you will need to remove and re-locate the tool arm and rest on the small rail located to the left of the headstock and attach the extension arm (big bit of metal with pins on - located on lathe shelf) to allow you swing the rest into the correct position.
  3. Rarely the speed selector seems to malfunction and lathe does not increase/decrease in speed. This is due to the variable adjusting pulleys inside which can get clogged with dust and grime - luckily this is a very simple fix and takes about 10 minutes.
    1. isolate the power
    2. remove the cover on the back of the headstock (3 screws)
    3. remove c-clip, washer and spring on pulley.
    4. apply WD-40 and gently remove the 2 part pulley from shaft (DO NOT be tempted to hit the pulley with anything - it is cast iron and will shatter - you can see someone has taken a chunk out of it already)
    5. clean pulley teeth and de-burr if required
    6. clean motor shaft and replace pulley, spring, washer and c-clip
    7. replace motor cover

Accessories

Drive Centre

A drive center, also known as a grip center, is used in the driving end of a machine (headstock). It is often used in woodworking or where softer materials are machined.

Live Centre

A revolving center, also known as a live center, allows higher turning speeds while avoiding burning and also produces greater clamping pressures

Face Plate

A lathe faceplate is a basic workholding accessory for a wood turning lathe. It is a circular metal (usually cast iron) plate which fixes to the end of the lathe spindle. The workpiece is then clamped to the faceplate, typically using t-nuts in slots in the faceplate, or less commonly threaded holes in the faceplate itself.

Tool Rest Extension Arm

The Extension Arm is a very useful accessory and enables the user the turn larger diameter pieces - especially when you rotate the headstock 45 - 90°

Maintenance

25/10/2018 - Fixed Speed Control - Ryan Hale - Kinetic friction cones had seized on the Motor shaft. Cleaned and lubricated and now moving freely and fully working again.

NOTE I Did notice that both the motor cones and the shaft cones have chunks taken out of them. I don't see this as a safety concern as the cones and pulley are shielded by a heavy metal plate/cover. The only detrimental affect may be that the pulley belt may wear out and ultimately snap prematurely or it may have chance to jump off and will need putting back on. - That said I will look into prices for replacement cones

24/01/2019 - Fixed Speed Control - Ryan Hale - Kinetic friction cones had seized on the Motor shaft. Cleaned and lubricated and now moving freely and fully working again.
