    scott the only thing that worries me is the resin can slowly wear and not remain flat. remeber the stone is MUCH harder than the resin and cuttings can wear out the resin. when polishing using same the same can happen. even with the tin and other polishing laps this can happen. i quizzed them maker of the batt lap, a better than 90 persent tin and an alloy to harden it up so surface resists surface change, and it has 2 sides to use. other than cabbing i dont use loose diamond grit or compounds. for faceting hand charged diamond lap are very pass’a/ancient. diamond pressed in can come back out and contaminate very easy. i don’t recommend hand charged nor compound charges lap for polishing. as for polishing the very fine diamond powders are usually not a contaminating problem rather a polishing thing. used 50,000 diamond on tin is extremely fast polishing. i’ve seen facets done all the way with resin and sooner or later you can see rounded and/or out of flat facets
