kjk: Hey Ya'll, Just signed up to the formum. About 5 years into tumbling, have 1 - 3# & 1 - 15# rotatary and 1 TV-5. Been using voltage regulators to control speeds which has improved end results. Nov 6, 2024 21:46:04 GMT -5

kjk: My first try on Fluorite was about 5 years ago. Pre-shaped rough with dremel then used a 3 # rotary start to finish 90-220-500-TXP polish,all with ceramic fill. Nov 6, 2024 22:06:16 GMT -5

kjk: Second attempt with fluorite, 3# rotary for stages 1 thru 3 with 90-220-700 all with ceramic. Stage 4 TV-5 with 1000 and ceramic. Stage 4 TV-5 with 1200 and corn cob. Looks Gem quality and ready for final polish. Nov 6, 2024 22:11:20 GMT -5

kjk: looking for suggestions on final polish for Fluorite. Been sitting on these gems for a while because I don't want to bust them up like my first try. Have been leaning towards TV-5 with #61 Rapid Polish, ceramic, 1/2 cup water, TV-5 approx 60v (1/2 speed) Nov 6, 2024 22:21:39 GMT -5
