I am brand spanking new to Faceting, My UltraTec has yet to ship. But I am excitedly getting prepared. Am I wrong or correct in thinking we need a separate lap for each type stone? I mean, multiple 600’s. Or such. And when you say TIN lap, do you just mean Aluminum or a brand? And how many Masters do I need? I so wish there were a club near me, Morgantown MS.
