Lesson 1Tools and equipment: cutting tools (utility knives, rotary cutters, hot knives), heat tools (heat guns, thermoplastic molds), sanding tools, Dremel/rotary toolsReview essential cutting, shaping, and finishing tools for EVA foam. Compare knives, rotary cutters, and hot knives, then move to heat guns, shaping forms, sanding blocks, and rotary tools, with tips for safe use, upkeep, and clean results.
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 flammablesLearn how to set up a safer EVA foam workspace. Topics include ventilation for fumes and dust, respirators versus masks, gloves and eye protection, fire safety around heat tools, and correct storage of flammable coatings, solvents, and glues.

You will compare craft foam, foam board, PVC and balsa armatures, aluminum wire, filler foams, and structural cores, with guidance on bonding them securely to EVA surfaces.

Learn pigment choices, thinning ratios, layering methods, and UV-safe topcoats that resist cracking while preserving surface detail and flexibility.
