2 - 2X4 - 11"
2 - 1X4 - 11-3/8"
Couple of wood screws and glue.
Cut your 2x4 and 1x4 to length. This may differ depending on the number of blades you have. Mine is designed to hold 10 ten inch blades. On the 2x4's cut 1" deep slots on the flat side. Measure out your slots to be 3/4" apart. For mine I just ran my widest blade through twice creating a 1/4" cut. Do this on both 2x4's. Cut your 1x4 to 11-3/8". You are now done cutting. Assemble the wood with the 1x4's on top of the 2x4's. I use glue and screws to strength. Screw your pieces together and when you are done, your final dimensions should be 12-1/2" high and 11-3/8's wide. As I said earlier, if you have more blades, increase your dimension to fit the number you have. You can leave it raw wood, paint or stain it. Install your blades, find a suitable location and you are done. Hope this helps. Thanks for looking and check out my other submissions.
