Routing raised panel edges in one pass produces tear-out and it's risky. Spacers taped to a router-table fence let you rout gradually without constant adjustments. First mount a panel-raising bit onto a table-mounted router set to its lowest speed. Test-cut scrap the thickness of the panels to set the final profile. Then make eight spacers from 18 " or 316 " plywood, and double-faced tape four on each side of the router-table fence. Rout all four edges of each panel, starting with the ends; then use a putty knife to pry off a spacer from each side, as shown above. Repeat for each panel, removing pairs of spacers until the panel rides against the fence on the final pass.
