Knock-Down Cutting Support Grid

Instructions

1. 1. Cut the Rail Parts

   • You can start by making the Lower Rails, as shown in the cutting diagram. We used #1 pine, but lesser grades will work, too. Just make sure the boards you choose are straight and free from twist. Even though the Lower Rails are 8' long, and the boards you’ll buy are 8' long.
   • Check them. Sometimes the boards are slightly long, so you’ll want to cut them to length.
   • Then, following the cutting diagram, cut four Upper End Rails, Four Outer Rail Fillers, and two Center Rail Fillers to length. If you’re using a circular saw for your cuts, check out the how-to video for tips on getting square cuts. We also cut four Riser Blocks to elevate the rail assemblies to the correct height in our Mobile Project Center and Track Horse.

2. 2. Assemble the Rails

   • Now you can assemble the parts to create the completed rails. We only used glue—no screws or nails. That way, when you’re cutting on the grid, you won’t have to worry about your saw blade hitting a nail or screw.
   • Lay the parts out on your work surface, or on the floor, and make sure you have them all oriented correctly.
   • Then glue each piece to the Lower Rails, using scraps of 2x2 as spacers to ensure proper spacing—but make sure you don’t accidentally glue the spacers in. You can clamp the pieces or wrap them with masking tape while the glue dries

3. 3. Cut the Cross Bar Parts

   Now you can cut the parts for the cross bars, as shown in the cutting diagram. You’ll need four Upper Cross Bars, four Lower Cross Bars, and eight Cross Bar Fillers. You can also cut two 2x4 Cross Bars. They’ll fit in the tracks on top of either the Kreg Mobile Project Center or Track Horse. If you’re cutting with a miter saw instead of a circular saw, check out the how-to video for information on using stops to more-easily cut multiple parts to the same size.

4. 4. Assemble the Cross Bars

   Now, using the same methods you used to assemble the rails, you can assemble the cross bars. Once again, use scrap 2x2s as spacers.
