SOLAS Sheet Metalworking study plan

Set up a personal drawing kit (scale rule, dividers, set square, protractor) and lay out a title block to a recognised standard

Practise third-angle orthographic projection by drawing three views of a simple folded bracket on A3 paper

Convert a dimensioned drawing between millimetres and inches and record five worked conversions with the method shown

Identify and name the standard line types (visible, hidden, centre, cutting-plane, dimension) on two sample drawings you draw yourself

Produce a full-size development (flat pattern) of a simple 90-degree bend using bend allowance calculated from a stated K-factor

Calculate bend allowance and bend deduction for three different material thicknesses and radii, showing the formula and units

Measure five workshop items with a steel rule, vernier caliper and micrometer, and compare readings to assess repeatability

Interpret a tolerance block and state whether three given measured dimensions pass or fail

Demonstrate correct marking-out from a datum edge using a scriber, odd-leg caliper and dividers on a practice sheet

Cut straight and curved profiles in 0.8 mm mild steel using hand snips, maintaining a cut line within 1 mm of the marked line

Set out and cut a corner notch and a flanged corner, then describe why the notch size depends on flange height

Select and justify the correct snip type (straight, aviation left/right, double-cut) for three given cut geometries

Form a 90-degree bend in a fly press or hand bender and check squareness with a set square, recording the deviation

Explain springback and state how overbending compensates for it on a given material

Roll a simple cylindrical form and check diameter and roundness against the drawing

Identify the main parts and safe operating checks of a box-and-pan folder and a bending machine

Produce a riveted lap joint and a riveted butt joint with a strap, spacing rivets to a stated pitch and edge distance

Select rivet diameter and length for a given sheet thickness and explain the calculation

Compare soldered, riveted and mechanically fastened joints for a given service condition and justify a choice

Assemble a small fabricated box or tray from developed patterns and check overall dimensions

Plan and sequence an installation task: mark fixing positions, set out levels and datums, and fix a fabricated item to a frame

Describe how to allow for expansion, thermal movement and clearance when installing sheet metal cladding or ductwork

List the hazards of the fabrication and installation tasks you have performed and match each to a control measure

Demonstrate correct selection and pre-use inspection of portable power tools and abrasive wheels

Carry out a workshop risk assessment for a sheet metal bay and record likelihood, severity and residual risk

State the legal duties of employer and employee under health and safety legislation in your jurisdiction and how they apply to you

Demonstrate safe handling and storage of sheet material, including edge protection and manual handling limits

Identify fire precautions and emergency actions relevant to hot work, sparks and solvent use in a metalworking shop

Complete a timed 60-question mixed mock covering all four domains and score it by domain

Re-work every mock question answered incorrectly and write the correct reasoning for each

Recite from memory the key formulas (bend allowance, rivet length, pitch and edge distance rules) and the main safety duties

Review weak areas identified by the mock and produce a one-page revision sheet per weak domain
