This is the Sketchup view of my Large Sled, hopefully will start it this weekend. I do most crosscut on the radial arm saw up to about 14”, so I need a large sled for sizes beyond that. It will take a panel up to 24” wide. MDF base, high impact acrylic guard (thanks MickeyD), the rest is 3/4” birch ply. Runners will be aluminum bar backed with MDF.
