No miter gauge on the market can offer you the margin of safety provided by this “sled”. The versatile hold-down clamp included with every Dubby will give you an extremely safe way to cut small pieces, and will easily pivot out of the way when you don’t need it. With 35 lbs. of hold-down pressure, the clamp will hold small pieces as you cut them with your fingers out of harms way. A. Depth of table saw top: This measurement must be at least 27″. If this dimension is less than 27″, the table saw top will be too small to safely support the Dubby platform. Under some circumstances, adding a rear support table to the saw top may solve this problem, but you should contact us to verify it would allow you to install the Dubby on your saw. B. Distance from the saw blade to the edge of the extension: This measurement should be at least 19″. You must insure that the Dubby platform will not overhang the outside edge of the extension. C. Width and depth of miter groove: The miter grooves on the saw should be 3/4″ wide and 3/8″ deep. The grooves may be slightly undersize or oversize, as our adjustable/self-adjusting bar will accommodate these variations. D. Distance from the left miter groove to the blade: For “standard” Dubby orders this measurement should be between 4″ and 5 3/4″. If this measurement is not between these measurements, the dubby will not fit
