Lesson 1Measuring and calculating metal strip length: formulas, allowances, and verification checksDevelop reliable methods fuh calculate ring blank length using ring size charts, circumference formulas, an metal thickness allowances, den verify wid mandrel checks an test bands fuh minimize waste an ensure accurate sizing.
Reading ring size charts correctlyUsing circumference and pi formulasAdjusting for gauge and hardnessAllowances for solder seam filingVerifying length on mandrelLesson 2Post-solder cleaning: pickle handling, rinsing, neutralizing, and visual inspectionClean di ring safely afta soldering by using pickle correctly, handling tongs an containers, rinsing an neutralizing acids, an performing visual inspections fuh confirm all oxides, flux, an residues dey fully removed.
Safe pickle setup and labelingUsing copper or plastic tongsRinsing and baking soda neutralizingRemoving stubborn flux residuesInspecting seams and porosityLesson 3Surface refinement and texture options: plan for flat, hammered, or engraved finishes and sequence for eachPlan an execute surface refinement by leveling tool marks, den applying textures such as flat, hammered, or engraved finishes een one logical sequence dat preserves edges, protects dimensions, an supports lata polishing steps.
Removing deep scratches and pitsCreating uniform flat finishesHammered texture tools and patternsBasic line and dot engraving passesSequencing texture before polishingLesson 4Rounding and truing: filing sequence, sanding progression (grits) and mandrel techniques to restore roundRefine di ring’s geometry afta soldering by truing on di mandrel, using controlled filing an sanding sequences, an correcting flat spots or flares so di ring become evenly round, consistent een width, an structurally sound.
