Hey Mike and Sue Danehy, got some help for you on silver scratches.
When I have to tighten stones AFTER polishing, such as on Platinum,
I USE A SOFT COPPER PUSHER, do all the necessary tightening, THEN I
USE A PINK PUMICE WHEEL. why? it has a grit number of only 1000, It
really cleans as it polishes! I even do some intricate pink wheel
polishing before the ring polisher tackles my work. It gives him an
overall help where he can’t get to certain areas with his big "chunky"
wheels. So I suggest you both try this new soft abrasive wheel, its in
the Rio Grande Tool Book page 348, catalogue year 2000,(second last,
from the bottom) #332-669 or # 332-657. wheel your work, then just
steam it after. NO POLISHING AT ALL !!! trust me! Gerry, the
cyber-setter, who lives in Toronto, Canada,eh?..:>) rain & cold!
