Roll 2-4 times (max) before annealing again (this depends on how stressed the metal becomes!) If you do get splintering, file it before you roll again. Always turn the T-bar in 1/3 - 1/2 turns to avoid over tightening and deforming metal. Never go straight to silver (practice on inexpensive metals in the same gauge).
