Glass and Aluminum Fabrication Lesson Plan

What a good one includes

• A dedicated personal protective equipment and material handling module focusing on heavy glass transport, suction cup safety, and aluminum cutting hazards.
• A section on reading architectural blueprints, calculating precise deduction formulas for glass sizing, and checking shop drawings.
• Step-by-step instructions for operating critical machinery, including drop saws, punch tooling, routers, and glass cutters.
• Detailed fabrication procedures for commercial storefront systems, curtain walls, and residential window framing.
• Hands-on guides for assembling corners, installing gaskets, preparing hardware preps, and mounting hinges or pivots.
• Field installation procedures, including setting blocks placement, wet or dry glazing techniques, and perimeter caulking.
• A practical assessment checklist with acceptable tolerance limits to verify apprentice competency before they work unsupervised.

Common mistakes to avoid

• Glossing over the physical mechanics of carrying glass, which leads to workplace injuries or costly breakage during the learning phase.
• Failing to define exact tolerance margins for cutting and fabrication, resulting in frames that do not fit properly on-site.
• Overloading the plan with classroom theory while neglecting structured, supervised hands-on practice with actual scrap aluminum and glass.
• Omitting the critical techniques of joint preparation and sealant application, which are the primary causes of post-installation water leaks.
