Thin strips should be cut on a table saw with the wide board against the fence and the fence moved in for each cut, however it is difficult to accurately adjust the fence for each strip to be the same thickness. This gauge allows you to simply slide the fence over until the stock hits the guide. Because there are so many different types of table saws I have not given any measurements for the lengths of the parts, this should be obvious when the strip is in the miter slot.
Cut a stip that fits snugly in the miter slot of the table, with a 5/8″ spade bit drill a pocket for the bolt head about 1/8″ deep, then drill 1/4″ hole for bolt. Cut a slot in a piece 1″ wide hardwood that is long enough to extend to line up with the saw blade, round the outer end. Fasten the two pieces together with a 1/4″ carriage bolt, washer and thumb screw.
Mark the width of the strip to be cut on the material, set fence, then place gauge in miter slot and adjust guide to touch material. Remove gauge, make the cut, insert gauge, with material against fence, slide fence over until material touches gauge, remove gauge, cut, continue in this manner.
