JC Wood Technology study guide
JC Wood Technology · Work through your exam, one topic at a time.
JC Wood Technology is a school- or college-level qualification in the design, making and understanding of timber products. It suits pre-vocational students, apprentices beginning joinery or cabinetmaking, and general-technical learners who need a materials grounding before specialising. The JC Wood Technology study guide has 9 sections and about 2,757 words.
01Wood science: timber structure, growth, seasoning and moisture behaviour
This domain asks you to connect tree growth and cell-wall structure to the way timber behaves in service: shrinkage, movement, drying defects and equilibrium moisture content (EMC). Expect calculations of moisture content (MC) and questions on why flat-sawn boards cup and shrink more in width than thickness.
345 words, about 2 min02Timber identification, classification, defects and material selection
Identification from visible features, correct use of classification systems (strength, durability, treatability), recognition of defects and defensible selection of material for a service environment. Botanical softwood/hardwood is not the same as trade softwood/hardwood.
304 words, about 2 min03Hand tools: selection, safe use, sharpening and maintenance
Correct choice of hand tool, safe technique, and the sharpening and maintenance routines that keep edges accurate. A plane iron is honed at about 25° with a 30° microbevel; the back must be flattened first.
313 words, about 2 min04Portable power tools and woodworking machinery: set-up and safe operation
Pre-use checks, correct set-up, guarding, feed direction, extraction and safe operating position for portable and static machines. Guards, riving knives and anti-kickback devices stay fitted.
335 words, about 2 min05Joints and construction: carcass, frame, dowel, mortise-and-tenon and sheet-material work
Choosing a joint that suits the material, load and appearance, and setting it out so it assembles square and strong. Carcass joints: butt (weak, needs fixings), rebate, housing/dado, dovetail, dowel, biscuit and cam/confirmat.
302 words, about 2 min06Adhesives, abrasives, finishes and wood preservation
Matching adhesive, abrasive and finish to the substrate and service conditions, and applying preservation correctly. PVA: interior, D3 for humid interior, D4 for exterior non-structural; not for continuous loading or structural use unless specified.
306 words, about 2 min07Technical drawing, design process and working to specification
Reading and producing working drawings, interpreting dimensions and tolerances, and following a design process from brief to evaluation. Orthographic views: first-angle projection places the view from the left on the right; third-angle places it on the same side.
282 words, about 1 min08Health, safety and workshop organisation, including dust and chemical hazards
Risk assessment, control hierarchy, machine and dust safety, chemical safety (COSHH/SDS), electrical safety, housekeeping and emergency arrangements. Follow the hierarchy of control: eliminate, substitute, engineer controls (guards, LEV), administrative controls, then PPE.
292 words, about 1 min09Sustainability, sourcing and environmental impact of timber and manufactured boards
Responsible sourcing, chain of custody, environmental comparison of timber and boards, and design choices that reduce impact. Legal timber is not automatically sustainable.
