The Speedy Lathe Gage is used to set lathe tools on the spindle axis for optimum cutting conditions. To use this gage first contact the mouth of the gage against a piece of round stock and set the contact face on the gage on the cutting edge of the tool. Then adjust the tool until the bubble is centered in the level. This procedure ensures the cutter is accurately placed on a plane that intersects the rotational axis of the spindle. (Note: it is necessary for the lathe to be leveled for the Speedy Lathe Gage to work properly)
