Introduction to Safety Precautions
Workshop rules and regulations: safety precautions to personnel, tools and equipment.
(a) Marking-Out, Measuring, and Testing Tools
(b) Cutting Tools
(c) Holding and Supporting Tools
(d) Percussion (Driving) and Impelling (Striking) Tools
(e) Boring Tools
(f) Abrading Tools
Theory of Common Woodwork Joints, Classification and Construction
Free-hand sketches of joints: scaled and dimensioned drawings with details of different joints. Halving joints (tee, dorner, mitred), simple mortise and tenon joints, e.g. stopped, through; housing (stopped through, dovetailed), dovetail joints (excluding secret mitre), pin or finger joints, edge treatment, and joints for manjufactured boards; framing joints, door construction and fitting, securing table tops, simple design problems and factors affecting design of joints.
Adhesives, Fastenings, Fittings and Finishes
(a) Adhesives: various types of glues to include: PVA animal, synthetic, contact and other common glues readily available. Application of glues in teh construction of pieces of furniture or other structures; and conditions for proper adhesion of surfaces to be joined.
(b) Fastenings and Fittings: Free-hand sketches of hardware; correct selection and application of hardware, e.g. nails, screws, hinges, locks, catches, handles, latches.
(c) Finishes: Comparative study of finishes and their application; selection of appropriate type of finish, e.g. stains, polishes, varnishes and paints.
(a) East African and Exotic Common Trees and Timbers: The growth and structure of a tree, e.g. podo, musizi, mahogany, elgon olive, muvule.
(b) Conversion and Seasoning: Methods of conversion and seasoning timber, behavior of timber during seasoning; simple moisture content testing and formula for the determination of moisture content percentage; causes of defects during seasoning; simple strength testing of wood (mechanically); marketable sizes of timber.
(c) Diseases and Defects: Pests, worms and fungi.
(d) Preservation and Storage: Preservation; comparative preservation methods, impregnation, applied pressure, tank dipping, painting and spraying.
(e) Timber Manufactured Boards: Manufacturing processes of manufactured boards, their characteristics and uses; advantages and disadvantages of manufactured boards, e.g. battenboard, laminboard, and blockboard (softboard).
(f) Manufacturing Processes of Veneers and Plastic Laminates: Cores, cross or counter band, back and face, glues used in veneering; cutting techniques and applications of various types of laminations and veneers and ordering.
(a) Dress Press and Electric Hand Drill: Structures and principles of operations. General safety rules for each. Boring operations including spindle speed and safety rules.
(b) Wood Lathes: Structure, accessories and principles of operation. General safety rules for the lathe. Face plate turning and turning between centers and their safety precautions. Fixing on job, cutting speed selection, boring techniques and polishing job on the lathe.
(c) Shapers: Circular saw machine; Planing machines. Structures and the uses. General safety rules for each.
Design and Drawing
(a) Basic Elements of Design: This should include line, planes, mass and color; creativity as well as principles of composition, proportion, rhythm, contrast and symmetry and all the activities that are necessary to develop a product.
(b) Problem Solving: The candidates should tackle various problems which call for identification of needs in given circumstances or observations, therefore resulting into design brief. Various materials should be used to build models that will help to visualize the problems before the final products are put into use. Generally, this leads towards a "a creative approach" and "problem solving".
(c) Working Drawings:
(i) Working drawings with the exact dimensions and the details necessary for the construction of the project.
(ii) A pictorial drawing with the exact dimensions and the details in three-dimensional form.
(iii) Reduced scale models showing three dimensions in the same proportions as on the finished full-scale project.
(iv) Listing all the necessary materials while paying attention to sizes and quantities required so as to determine the total cost of the whole project.
