Instructions for the Lot O Tumbler Detailed Instructions for the Lot-O-Tumbler & Lot-O-Twin Tumbler Step 1: Roughing. In the roughing cut the goal is to remove the undesirable outer portion of the agate. This usually takes the longest time and is not as critical as some of the other steps. With the Lot-O-Tumbler, use of a medium grit such as 180-220 (we use 120-220 grit) will do the fastest job of removing this outer material.

(The use of a coarser grit such as 60-90 silicon carbide does not improve the performance. Heroes Of Newerth. ) The grit has to cling to the agate as it rotates in the barrel. Coarser grit tends to fall off the agate as it rolls and delays the roughing action. In order to grind away the rock, the grit must be in between the agates when they come together. If two rocks merely tumble together, there will be a buffing action but the outer portion will not be removed.

Anything which keeps the agate from coming together on the silicon carbide grit will reduce the action of removing the undesirable rock. The best action is achieved by wetting the rock just enough for the silicon carbide grit to cling to the agate as it tumbles. This is achieved by putting just enough water in the unit to insure that the agate is wet. If too much water is used, it will cushion the vibration and increase the roughing time. For a full barrel of agate in a variety of sizes, start with only the agate wet.

If the agate cannot be rinsed in 12 hours add 1 capful (red tumbler cap) of water. The Lot-O-Tumbler breaks down the 180-200 grit rather rapidly. Therefore, on the first two days of tumbling, there should be a fair amount of grit placed in the unit. The usual amount is about two tablespoons of silicon carbide. When the agates are washed daily mud and grit will be observed coming out.

There should be a small amount of the original grit remaining to insure that the unit is grinding over the full period of time. On the last day of the 180-220 grit, it is best to use a light charge of silicon carbide so that all the grit will break down and the agate will start to polish.
