I have an old Craftsman table saw that was made when Craftsman still made respectable machines. I am planning on extending the table to allow 24" ripping capability. The cast iron table is already drilled to accept an extension, and I plan on welding my own extension and bolting it to the existing table. The fence on said saw has a rack and gear setup to finely adjust the fence. I would really like to make a longer rack to coincide with the table extension. I haven't made any measurements on the teeth on the rack, but they are pretty fine. Does anyone have any suggestions on making a longer rack? I have a Grizzly M/D at my disposal, but can't figure a way to do it. Maybe some sort of ttapered endmill? I've never seen such a creature, but that don't mean it don't exist!
Thanks in advance.
