About Shars 8 Inch 3 Jaw Self Centering Scroll Lathe
To achieve the .0005" radial runout and repeatability, it's required to use the 4 micro adjustment set screws to true the designated ground bar stock, not the chuck body. Do not attempt to put the indicator on the outside diameter of the chuck body to dial it to zero first as this would create more runout on the bar stock. The adjustable chuck is intended to give high repeatability clamping on a particular bar stock size after the set screw adjustment. After the adjustment is made on a particular bar stock rod, for example 1/2", it's required to true the bar stock again when clamping a different size diameter, for example 1".
