MachineWOOD TURNING LATHE

Suitable materials and processes:

Suitable for use only with wood.There are two distinct methods of turning wood: spindle turning and faceplate turning. In spindle turning, the wood is fixed between 2 points. The spur centre digs in to the wood and is powered by a motor. The other, a hard centre or a live centre may be a point or set of points in the tailstock. In faceplate turning, the wood is secured with screws to a faceplate or in a chuck or jig. The tailstock and a centre may also be used for added support on large pieces with a faceplate. Most bowls, platters and many vessels are faceplate turned, while, Pens, furniture legs, spindles, and some vessels are spindle turned. The method used may differ depending on the shape of the blank and the technique of the turner, and both methods may be used on the same piece.

BS4163 Main points:

Hazards- Work pieces can fly off if not correctly mounted to a face plate, chuck or between centres- Hands and clothing can become entangled in moving parts of the lathe- Hand held woodturning tools can become trapped between the rest and the work piece.- Timber particles can ban fly off poorly selected or prepared woodLack of space around the machine can lead to the operator being pushed by passers-by- Slippery floor surfaces or loose items around the machine can cause slips that result in contact with moving parts.- Inadvertent starting of the machine can present a hazard- Wood dust can be inhaledIt is essential the machine is provided with:- A means of electrical isolation using a fixed switch-disconnector on or adjacent to the machine and that it is controlled by a starter incorporating overload protection and no-volt release- A conveniently positioned, mushroom headed stop button or other suitable control device that can quickly stop the machine in an emergency- Fixed guards (removable only with the use of a tool) or interlocked guards that enclose the drive mechanismsOnly one person at a time should operate the machineTimber should be inspected carefully to ensure it is free from defectCare should be taken to ensure the work piece id securely mountedOnly one side of the machine should be set-up for work

CLEAPSS Main Points:Trapping - Hand-held turning tools can become trapped between the rest and the workpiece.Flying Objects - Workpieces can be thrown violently if not clamped (for mortising) or if not mounted securely on a faceplate, in a chuck or between centres on the lathe. Tools can also be projected. Faceplates may also fly off if a brake is applied too fiercely.User Injury - Human contact with moving parts

Common Problems:- Electrical isolation has not been switched to off and the starter button accidently starting the machine- The Safety Guard is not applied- Clothing or hair is caught in the machine- Work piece is not held firmly to the worktable and spins around- Work piece fragments fly into unprotected eyes- Too many persons around the machine may
