Fluidmotion Wheel Dresser Operating Instructions The only tool required for setting is a micrometer. To obtain a convex radius: 1. Obtain micrometer reading over diamond as in photo "A" Assume it to be 2.531 2. ADD desired convex radius. Assume it to be +.069 Sum of reading + radius = 2.600 3. Loosen gib and set total reading over lower "mike" pins photo "B" (use Micrometer). 4. Tighten gib and you’re ready for action photo "C". To obtain a concave radius: 1. Obtain a micrometer reading over diamond as in photo "A" Assume it to be 2.900 2. Subtract desired concave radius. Assume it to be 2.142 Sum of reading - radius = .758 3. Loosen gib and set difference over lower "mike" pins photo "B" (use micrometer). 4. Tighten gib and you’re ready for action photo "C". To obtain zero radius or dead center: 1. Obtain micrometer reading over diamond as in photo "A" Assume it to be 2.000 2. Loosen gib and set same reading over lower "mike" pins photo "B' 2.000 3. Tighten gib and you’re ready for action photo "C". This will be dead center or zero radius. To obtain one angle: 1. Loosen knurled knob at rear of swivel base. 2. Grip the two ring pins and set desired angle by reading vernier at rear of swivel base. 3. Tighten knurled knob to lock pins at desired and you’re ready for action. To obtain two angles: 1. Loosen knurled knob at rear of swivel base. 2. Grip the two ring pins and move together until desired vernier reading for lower pins is obtained. 3. Swivel dresser upright in opposite direction until desired vernier reading for upper pin is obtained. 4. Tighten knurled knob to lock pins in preset position for two angles and you’re ready for action. 5. When setting for two angles set lower ring first. It is prelocked and will maintain set position. To dress two angles tangent to a convex radius in one continuous motion: Complete the desired angle settings (from To obtain two Angles) previous steps 1 thru 5. The ring pins will now be locked in desired positions and they become the tangent points where the angle joins the radius. Swing the upright against one stop and activate the angle dressing handle in the direction the diamond is to go and then return to center position. Swing around the radius to the other stop and activate the angle dressing handle for the other angle. Repeat until full form is dressed with the diamond, then spark out and form has been completed. The dressers are designed for repetitive accuracy as long as the diamond comes into contact with the full form each time the wheel is dressed.       A. Measure over diamond point to back of micrometer plate B. Add required convex radius or subtract required concave radius. C. Tighten gib. Dresser ready for action.
