Router Mortising Machine

You’ll be creating precision mortises with ease using your router’s motor and this shop-built machine. The secret to its smooth operation is ordinary metal drawer slides.

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.

What you get:

  • 15 pages of step-by-step instructions
  • More than 60 full-color photos, illustrations and exploded views
  • Includes tips for setting up and cutting perfect mortises
  • Cutting diagram. Materials list. Project sources

Overall project dimensions:
26"W x 23 1/2"H x 21 3/8"D

This Woodsmith Plan is a downloadable PDF file that you save to your computer after you complete your order.
