Router Mortising Machine

Complexity is the big obstacle to most shop-built mortising machine plans. This design has a “keep-it-simple” philosophy. It’s mostly built from plywood parts that are glued and screwed together. The moving components — the router carriage and sliding table — operate with heavy-duty, full-extension drawer slides. A no-nonsense stop system and a commercial toggle clamp make cutting identical mortises a snap. Common T-nuts and studded knobs round out the hardware list. This mortising machine uses a medium-sized router motor as the power source. I find that a variable speed router gives you more versatility. But even with a single-speed router, this machine will make creating accurate mortises a quick and easy process.
