Working on a Solderite board, decide on placement of a 2mm jump ring, three 1.8mm dots, and a 4mm bezel cup. When pleased with the placement, remove the jump ring. Place a small dab of medium paste solder where the jump ring will be placed. Press the jump ring into the solder. Remove the dots. Place small bits of medium paste solder in those spots and press the dots into it. Butter the back of the bezel cup with medium paste solder and press into place. Heat until the solder flows.
