How To Rout MortisesBesides your everyday routing tasks, there's one other job where this table shines — routing mortises. It turns a simple router table into a mortising machine. The key to mortising accurately lies in inserting the palm router horizontally on the back of the table, as shown in the photo at right and the drawings below. All it takes to do this is to switch the positions of the router plate and filler plate. Make the Hold-down. Before getting into the steps to mortising, it's a good idea to make the hold-down shown below as well. Not only does this keep the workpiece firmly against the table, it also acts as a guide to rout the mortises. The Setup. The drawings below show you the simple, three-step Perfect Mortises. An ordinary straight bit and a simple hold-down is all it takes to rout mortises using the multi-tool. process for making each mortise. But there are some additional things I want to highlight. First, when routing, you'll move the workpiece from left to right. (This is the reverse of how you would typically use the router table.) And second, it's best to rout the mortises in multiple passes. This does several things: it allows the chips to clear easier so you get a cleaner cut, you'll prevent burning, and it prolongs the life of both the palm router and the bit. ▲ Setting up the Bit. Use a workpiece as a set-up gauge to locate the router bit to cut in the center of the workpiece. k Position Hold-Down. Set the hold-down on the workpiece and align the notch with the edge of the bit. Then lock the hold-down in place. ▲ Rout Mortise. Use layout lines and the guide notch on the hold-down to rout the mortise. Take shallow cuts for best results. ROUTER PLATE FILLER PLATE workpiece HOLD-DOWN HOLD-DOWN FACE (2 x 12 - Vi Ply.)
