Tricks for truing lumber without a jointer
To rip a straight edge on boards
Build this sled and use it as a secure platform. To make a T-slot, use a Forstner bit to drill 3/8"-deep starting holes where shown; then run your router against a straightedge clamped to the sled base and plow the channel between the two holes with a 3/8" straight router bit. Without moving the straightedge, install a T-slot cutter bit and rout the channel.
To use the sled, let the rough edge of the workpiece overhang the sled and secure the workpiece with hold-down clamps (#35283, 800-279-4441, rockler.com). Butt the opposite edge of the sled against your fence and rip the crooked edge away, as shown previous slide, top.
