The Trim Saw Vise and Cross Feed is designed to slab small work samples. The vise jaws hold up to a 3-1/2" rock and will grip the work piece without blocks or shims. The cross feed adjusts 3-1/2" before stone must be repositioned in the vise. The end of the cross arm shaft has a "no bind" roller bearing and hook which ensures a smooth feed and prevents rocks from "riding up" the blade. This kit comes complete with a vise assembly, cross arm shaft, cross feed, knob, and weight feed cord. *Please note that this kit does not fit on #TSK186 and it doesn't come with a scale.
