How's this for ideas of how to fabricate the sled. Take a suitable length of 2x4. Determine the slope Cut the slope across the broad side, then cut in half Now you have the sleds for the slope and only need to shim the bottoms for suitable elevation along the length. Or you could make a platform from plywood. I use this for bass bridges. Cut a center section out for the bit to extend through. In mounting blocks that are glued to the underside are screws which act as adjustable feet. Adjust the height at each end above the bridge surface. Make several passes with the router, double checking bridge height from the board and refine platform height as needed. -- Regards, Jon Page
