Flattening Boards with a Router Sled

September 24, 2014

If you don’t have a jointer or a planer or you need to flatten something large or difficult to flatten, a building a simple sled for your router is a great solution.

    Why are the sides of the sled so tall?

    • The sides provide the beam strength. You don’t want the sled to sag under the weight of the router or due to any downward pressure you apply to the router as you are moving it back and forth.

    Hi Matt,

    Looks good. One question though; do you need a level floor or underground for the jig to rest on? I want to flatten a slab that’s 120″ x 55″. Do I need to place the jig with the slab on it on a level floor or underground like a sheet of ply?

    Kind Regards,

    Arnold Koster (The Netherlands).

    • Yes, the flattness of the finished slab will be correlated to the flatness of the foundation. Bowing or curvature of the floor might not be too impactful but check your setup for any twist. Thanks!
