I have only used the Lortone Grits. I bought the basic 4 Step Kit ( 60/90, 120/220, AO Pre, AO polish which I use in my home tumbling, but at work
I start with 46/70 then 12/-220 then 600.... I was looking at the Lortone site and see they sell a 3F that appears to be 320/400. They also sell
Alpha Alumina Polish which I believe to be "finer" than the regular AO.
Does anyone use the 3F or the Alpha Alumina? Just curious, what products you use.

In my 12 lb Rotary 3/4 full of Agate and Jasper
I go with 60/90 for a few weeks until my rocks are well rounded.
Then I will tumble with 120/220 for 2 weeks.
After that I will cleanse with Borax overnight.
For Polish, I like AO polish for another couple of weeks
Then burnish with a little bit of soap to cleanse the residue off.

My standard is 60/90 until smooth with no cracks/pits
Stage 2 (220 + 1 tbsp borax) for 3 days in Vibe
Stage 3 (600 + 1 tbsp borax) for 2 days in Vibe
Stage 4 (AO Polish + 1 tbsp borax) for 2 days in Vibe

Rotary recipe:
60/90 until I'm happy (average 4 to 8 weeks with recharge every 2 weeks)
120/220 for 2 weeks
500 for 2 weeks (with pellets)
Tripoli (pre polish) for 2 weeks with pellets
AO or Tin Oxide for 2 weeks with pellets (sometimes I run the AO out to 3 or 4 weeks)
Borax and pellets for a 24 hour burnish

This is my 1st tumble so this might not count for anything, but my method is as follows:
80 grit
220 grit
500 grit
Borax
500 A0 w/borax
1000 AO w/borax
AO polish w/borax
Borax
If there is something wrong with that let me know now as I am still in step 1.
I also have 60/90 for larger harder rocks or when I use my 10 lbs barrels.
