Lesson 1Measuring and calculating metal strip length: formulas, allowances, and verification checksDevelop sure ways to calculate ring blank length using size charts, roundness formulas, metal thickness extra, verify wid mandrel check and test bands to cut waste and sure correct size.
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 ring safe after solder by use pickle right, handle tongs and pots, rinse and neutral acids, do visual check to confirm all oxides, flux, residues gone full.
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 and do surface fine by level tool marks, den add textures like flat, hammered, or engraved in good order wey keep edges, protect size, support later polish.
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 roundFine ring shape after solder by true on mandrel, use control file and sand order, correct flat or flare spots so ring even round, steady width, strong.
Inspecting for flat spots and twistsUsing rawhide mallet to true shapeFiling high spots and seam flushSanding grits for sidewalls and edgesMaintaining consistent band widthLesson 5Marking, sawing, and initial filing: blade selection, kerf allowance, safe practices, and inspection pointsBuild clean, true ring blanks by mark lines, count saw kerf, pick right blade, safe saw and first file wey keep edges square, flat, ready for tight solder joints.
Marking layout with scribe or penChoosing saw frame and blade sizeSupporting metal and body postureManaging kerf and cut accuracySquaring ends with flat fileLesson 6Bezel making and setting (if applicable): forming bezel strip, sizing to stone, soldering bezel, setting, and burnishingIf design get stone, learn form and size bezel strip, solder strong to ring, den seat, set, burnish stone wid proper hold, avoid rock, gaps, damage to fine edges and faces.
Choosing bezel height and thicknessForming and sizing bezel to stoneSoldering bezel to ring basePreparing seat and testing fitSetting and burnishing the stoneLesson 7Soldering technique: torch control, temperature stages, solder placement, and quench/pickle sequenceMaster torch hold for ring solder by control flame size, angle, distance, read colour and flow stages, place solder good, manage quench and pickle to avoid warp, cracks, dirt.
Setting up safe soldering stationNeutral vs reducing flame controlHeating sequence around the bandSolder chip placement strategiesQuench, pickle, and safety timingLesson 8Forming on mandrel: progressive shaping, annealing schedule, and checking roundnessShape cut strip to ring using mandrel and mallet, follow step forming order, mix annealing right stages, check roundness and size often to avoid hard work and twist.
Choosing mandrel and mallet typesPre-bending strip into a curveProgressive forming up the mandrelAnnealing schedule during formingChecking roundness and ring sizeLesson 9Final finishing and polishing: compound sequence, polishing wheel selection, steam/ultrasonic cleaning checklistBring ring to pro finish by plan abrasive and polish compound order, pick wheels and brushes, manage heat, use steam or ultrasonic clean to show crisp, even last surface.
Planning abrasive progression stepsChoosing buffs, brushes, and mopsUsing tripoli and rouge effectivelyControlling heat during polishingSteam and ultrasonic cleaning checksLesson 10Preparing solder joint: joint geometry, fit-up, flux application, and pre-heating checksLearn prepare tight, clean ring joints by know joint shape, get exact fit, apply right flux type and amount, do pre-heat checks wey stop gaps, overheat, solder lack.
