Coping Sled

[morsa]

Thanks, PJs. You are right; a coping sled is a jig for end-grain cutting at the router table.

And yes, I use it for frame and panel doors. The coping sled would be used to cut the profile in both ends of the rails; the sacrificial wood behind the workpiece helps to avoid tearing at the end of the cut. The edge-grain cuts, on both the styles and rails, are made without this jig, supporting the workpiece against the fence, with the help of featherboards and push stick. Here you can find the procedure: Frame and Panel Door - Popular Woodworking Magazine

Of course, there are many profiles for these frame doors: MLCS Rail and Stile Carbide Tipped Router Bits 1

The technique for coping crown moldings or baseboards with a coping saw is somewhat different. See this link: Coping Crown Molding on Inside Corners
