I need to purchase a router that I can mount on a table that has a power stock feeder running about 20’ per minute. It will be used to cut a ½” wide ¼” deep channel in 5” wide 10’ long boards. After setting the correct height for the router bit the router will remain untouched until a new bit is needed. The router will need to have an accurate height adjustment and remain solidly in place. Which router and brand should I buy? I’m putting my Porter-Cable 890 routers in the garbage.
