nice agates you have there dave
i have a lortone as well ,not cheap but verry good ,i run a different barrel for each grit ,far less chance of cross contaminating the grits
if you are finding it hard to clean them dave i have another barrel that i use soap in it to clean the stones before i start polishing them, i leave them in the barrel for 1 day i have found that the lux washing powder works the best, a level teaspoon full to a 3lb barrel,
they come out clean and smell pretty to :lol:
