THE WORK BENCH
A very vital tool in the wood workshop upon which operations such as sawing, drilling, planning, chiseling and boring are all carried out.
Work bench fittings are:
- Bench Stop is a provision made to prevent the work piece from slipping off the top surface of the work bench during planning.
- Bench Hook is a device used to hold the job (or work piece) down during sawing or chiseling.
- Bench Vice is a device that has a torsion bar for opening the jaws to allow a work piece to be held firmly between them. Usually more than one of this is fixed on the bench.
- The Well is an important longitudinal hollow feature at the center of the work bench which serves as storage area for keeping bench tools during the process of work.
