HOW TO USE HOW TO USE HOW TO USE THE GRR-RIPPER he GRR-RIPPER 3D Pushblock System T is designed to glide along the rip fence of a table saw, so the rip fence must be parallel to the saw blade in order to maintain the parallel feed. he saw blade should be raised just T enough in height to clear the gullets from the top surface of wood pieces; normally about 1/4” to 3/8”. Pay extra caution on workpieces that are not equal in thickness such as tapered stock. The tunnel has a clearance of 15/16” in height.
HOW TO USE HOW TO USE WARNING! Always visually check the Saw Blade Tunnel has enough clearance for the saw blade to pass through safely before turning on the saw. IRREGULARLY SHAPED STOCK Ri p USING THE 1/4” LEG USING THE 1/2” LEG BALANCE SUPPORT SPACER Figure 16 Skew Handle (1) to exert “auto” pressure against the fence when pushed.
HOW TO USE HOW TO USE Resawing: You can resaw narrow stock in one pass without a bandsaw, planer or flat-bed sander. CAUTION! Stock must be square before resawing. Resaw to 1/4” (Inside Cut) or thicker in one pass as shown in Figure 18. Note Handle (1) location. Figure 18 Resawing stock thinner than 1/4”, or resawing wider stock, can be achieved in two passes by setting the saw blade slightly higher than one half of the width of the stock in the first pass.
