Used to cut curves in wood. Tenon saw A type of back saw with a stiff deep blade used to produce straight cuts / joints in wood. Homework 2 Learn the name, correct spelling and use of the tools shown in the table.
Homework 3: Risk Assessment Most workshop processes or activities are assessed for potential hazards and measures to minimize or control the hazard identified. Companies are required by law to carry out regular risk assessments of the equipment / processes they use. A Risk Assessment for the Pillar drill. Hazard Swarf (metal particles) or sawdust going into eyes Work spinning on the machine table Hair or lose clothing getting caught in rotating parts Drilling hand / fingers Getting a friend to help you The chuck key flying out of the chuck Leaving the Pillar drill switched on Control Measure Use the guard on the pillar drill and wear safety goggles Clamp the work to the machine table or use a machine vice (clamped to the machine table) Tie up long hair, remove lose clothing and wear an apron Clamp work or use a machine vice and avoid distractions Only have one person operating the pillar drill Never leave the chuck key in the chuck Remember to switch the pillar drill off once you have finished using it Homework 3 Learn the hazards and control measures that must be used when using the pillar drill. Identify the hazards and associated control measures when using the disc sander?
Homework 4: Glues and Adhesives Adhesives are used to bond materials together to form a permanent joint. There are a wide variety of adhesives available and it is important to select the correct one for the task and to use if safely. Name Material Drying / Cure Time Description / Use PVA Polyvinyl acetate Wood 4-24 hours Can be used straight from the bottle or brushed on to provide a strong joint. Parts need to be dry and clamped together while the Contact adhesive E.G. Evostick Hot glue stick Cyanocrylate (super glue) Liquid Solvent Cement (Tensol) Wood, metal and plastic Wood, metal and plastic Wood, metal and plastic Instant On cooling Instant Thermoplastics 10 minutes glue cures. A medium strength waterproof joint. Comes in liquid form and is applied using a spreader A waterproof adhesive but is relatively weak. Only suitable for modelling or temporary fixings. The glue stick is heated in a special glue gun. A waterproof, medium strength adhesive. Available, ready to use, in liquid form. Only suitable for small surface areas. A waterproof, medium strength joint. Comes in liquid form and is applied using a brush. Joints need to be held together while glue cures. Health and Safety: It is very important that adhesives are used safely. Read the instructions supplied with the product and follow them carefully. Remember also that materials need preparing before the adhesive is used. Homework 4 Learn the information on the different adhesives. What adhesive will you need to use to make the storage box?
Homework 5: Manufactured Boards Manufactured boards are made by converting logs into strips, veneers, chips or tiny particles, depending on the type of board being manufactured and then gluing them together to form sheet materials. Manufactured boards are stronger, more stable and more uniform than wide boards of either hardwood or softwood. Plywood Blockboard Manufacturing process Veneers glued together with each layer having the grain direction at rightangles to the previous one Strips of softwood glued side by side and then covered with a veneer on both sides Properties Flat, stable boards with uniform strength and thickness. Interior and exterior grades available A very strong and stable board Uses Furniture, boat building. Furniture Chipboard Medium Density Fibreboard MDF Thousands of tiny woodchips are mixed with glue and then compressed into sheets Tiny particles of wood are glued together and compressed with an adhesive to produce large, dense solid boards A low cost board. Difficult to join together, easily damaged by moisture A solid and stable board. Easily damaged by moisture Kitchen worktops when covered with a protective surface, flooring. Furniture, kitchen units, flooring. Hardboard Pulped wood treated to form fluffy brown fibres, mixed with glue and then compressed to form sheets A very low cost board, uniform strength in all directions. Cupboard backs, drawer bases. Homework 5 Learn the information on manufactured boards. Which manufactured board will be suitable to make the lid of the storage box?
