A Knockdown Router Table
This interlocking design needs no fasteners and stores flat.
Synopsis: When Massachusetts carpenter Joe Lanza changed his job-site tool setup from a heavy contractor saw on a rolling cabinet to a portable tablesaw, he discovered that he liked having less weight to push around but that he missed having a router-table extension wing. That led him to design and build a knockdown router table. Joe cut the pieces for the router table from a single 5×5 sheet of Baltic-birch plywood, and topped the table with a piece of 3/4-in.-thick medium density fiberboard.

I used to have a contractor saw with a router-table extension wing set up on a rolling cabinet. After a few years, I was tired of pushing a 250-lb. beast by myself, so I bought a smaller portable tablesaw with its own folding stand. The new saw was great, but I really missed the integral router table. For a while, I made do with a laminate-topped plywood box set on folding sawhorses that doubled as an outfeed table. This system worked, but it tended to slide around a bit. I scrapped that and built a more permanent table that’s too big to be easily mobile, but I needed something for on-site work.
None of the commercially available portable tables seemed good enough to justify the expense, so I thought about how to build a lightweight table that would set up and knock down easily, and be stable enough to serve as an outfeed table. I had seen a few plywood-table ideas that seemed to meet the first two criteria, but they didn’t look as if they would support sheet goods coming off a tablesaw. The best designs I have seen all have a self-locking feature, like the wedged through-tenon on a traditional…
