Lesson 1Tools and equipment: cutting tools (utility knives, rotary cutters, hot knives), heat tools (heat guns, thermoplastic molds), sanding tools, Dremel/rotary toolsGo over vital cutting, shaping, and finishing tools for EVA foam. Compare knives, rotary cutters, and hot knives, then discuss heat guns, shaping forms, sanding blocks, and rotary tools, including advice on safe handling, maintenance, and achieving neat finishes.
Utility knives, blades, and safe cutting habitsRotary cutters and cutting mats for clean edgesHot knives and heated blades for dense foamHeat guns, shaping forms, and controlled heatingHand sanding blocks, files, and sanding spongesDremel and rotary bits for carving and bevelsLesson 2Safety gear and workshop setup: ventilation, respirators vs. dust masks, gloves, eye protection, fire safety, safe storage of flammablesDiscover how to create a safer workspace for EVA foam work. Topics cover ventilation for fumes and dust, respirators compared to masks, gloves and eye protection, fire precautions with heat tools, and proper storage of flammable coatings, solvents, and glues.
