Explanation

Wood- and metalworking in the school workshop builds students’ work skills, work culture and interest in careers. From wood one can make boards, boxes, shelves, handles, frames, bird houses and chairs, and from metal shovels, boxes, screwdrivers, hooks, chains and other items. Tools fall into two groups: measuring and marking tools (metal ruler, square, folding rule, vernier calliper) and working tools (saw, plane, chisel, file, cold chisel, hacksaw, hammer); machines and machine tools speed up work and raise quality. The main processes are cutting, sawing, drilling, smoothing and joining. Each student has a separate workplace: tools used with the left hand are on the left, those used with the right hand on the right, and materials and exhibits are within reach. In the workshop an apron is worn, safety goggles are used for sawing, filing and drilling, and machines are switched on only with the teacher’s permission and supervision. In production, materials must be used without waste, tools sharpened on time and put back in place after work.

Worked examples
Making a box: measure and mark the boards with a rule and square, saw, plane, join with joints or nails, sand — each of these is a separate process.
In a metal box, smoothing the corners with a file is needed so that the edges are not left sharp: then hands do not get cut.
Class activity

Workplace audit: with the teacher look at one workplace in the school workshop and tick in a table whether the tools are placed correctly, order is kept and safety rules are observed. Tools are touched only with permission.
