Holding devices, cutting and pairing tools

Woodworking holding devices are the tools used to hold the work piece on the workbench. Woodworkers work on workbenches.  It is on these benches that various woodwork constructions are carried out. The centre of the bench is usually lower than its two sides.  This area is called a ‘well’ and its function is to accommodate the tools brought from the tool cupboard to the bench top during operations. The tools cannot fall or roll on to the floor or on anyone’s feet because this part is lower than other area of the bench.

The fittings are:

Bench vice: It is also called fitter’s vice. It is used to clamp or to hold jobs when the following operations are to be carried out on the bench, filling, bending, tapping, cutting, assembling parts, etc.

DEVICE

The Care of the Vice

(i) Always keep the vice clean.

(ii) The thread or the screw inside the vice should be oiled regularly.

(iii) Do not use the vice as an anvil for hammering a job

(iv) Always use hand force only to tighten the vice for holding the work piece.

  1. Bench Stop: There are many types of bench stops. Some are made of wood while some are made of metals.  It is a small strip of wood fixed on top of the bench. It is used to prevent wood from slipping off the bench top during planning.
  2. Bench Hook: This is used for holding jobs during cutting and chiseling on the bench. At the same time, it protects the bench top.
  3. The Clamps

(a) G-Clamp: This is a metal clamp used for clamping small jobs together. It is called a G-Clamp because of its shape which is in the form of letter ‘G’.  The clamp is ideal for holding small pieces of wood together

(b) F-Clamp: This is used like the G-Clamp. The clamp is in the form of letter ‘F’

cd

(c) Sash-Clamp: It is a larger clamp used for holding and drawing woods tightly together when assembling or gluing work.

Cutting and Paring Tools

Saws and Planes are used in cutting and smoothing wood in the workshop respectively. Saws are tools used for cutting wood. There are two main groups of saws: bench saw and curve cutting saws.

Curve cutting saws are:

  1. Coping Saw: This is used for cutting curve marked lines of wood. The blades can be adjusted to cut in any direction.

2. Fret Saw: This is used to cut curves in thin wood of 8mm thick or less. It is used to cut plywood

3. Bow Saw: Used to cut along curve marked lines but the wood has to be 50mm thick
