Practical work: making a cradle-swing (belanchak) and its technological map
A belanchak is an item in which a small child is laid and rocked. The wood must have no knots, cracks or other flaws, so the material is chosen carefully. A technological map is a table showing in what order, with which tools, measuring instruments and equipment an item is made; it also gives a sketch for each stage. The main parts of the belanchak are cylindrical and are shaped on a wood lathe. The usual sequence is: choose the material, measure and mark from the drawing, plane and saw to size, turn on the lathe, assemble the parts, sand and finish (staining, varnishing). Work on a machine is done only under the teacher’s supervision, with safety goggles and an apron, hair tied back and sleeves buttoned (no gloves near a rotating machine): fix the workpiece firmly, never touch it while the machine runs, hold the cutting tool with both hands and never leave a running machine unattended.
In groups draw in your notebooks a four-row technological map for a small item (for example, a bookshelf): work sequence, tools, equipment. Use no tools; only plan on paper.
