Smart people would actually have the countertop notch down 4" for a standard miter saw such that the material lays flush on the table. Normal people would have full runners to make a continuous track elevated for the material. Lazy people find scrap to make a quick shim when they’re cutting something a bit too long. That was me. Until today!
Behold my makeshift fastened shim system. 4" 2x4 atop 8" 2x4 atop 12" 1x6, making for 4" height overall. The edge of the highest point is set 24" away from the blade. Well that sort of helps but what if the piece is even too long for that? FEAR NOT.
You see? They pivot! Open them up 180 degrees and you’ve got support up 43-1/4" away from the blade.
“Sooo...this is better than a continuous track... how?”
It isn’t!
“Oh.”
