The Eliminator is very easy to use. You can insert the tenon into a handle and begin cutting immediately. On smaller items without much reach it can be used without a handle.
It is easier to use with a draw (pulling cut) but can be used pushing or pulling without fear of the deadly catches. Generally, I start with a drilled center hole (3/8") to gauge the total depth of the vessel, but it is not required. Just start in the middle of the vessel with the tool on center line, put the flat of the tool on the tool rest and sweep the cutter head toward the rim keeping a light pressure downward on the tool rest.
Keeping the flat of the tool on the tool rest gives you an automatic 45 deg. slant for the cutter and allows you to make smooth sweeping cuts. This is not a scraper, it cuts very clean shavings, not sawdust.
The tool is designed with two flats on the barrel that lay on the tool rest. When you are running your lathe in the forward direction use the flat that tilts the tool to the left for a pull or pull cut . If running in reverse just reverse the procedure by using the other flat.
The Eliminator works quite well on the exterior also. The mini eliminator is great for detailing and for coves and beads. I recently watched Dale Larson turn a 3" ball and a 6" bowl using only the Eliminator tool for both forms.
After several hours of cutting you may need to loosen the insert screw and rotate the cutter slightly. Be sure you tighten the screw firmly. The cutter should not revolve.
