Step 5 Cutting grove for steel cable

Tools:
Pencil
Tape Measure
Drill
Bar Clamps
Table Saw

Materials:
1"x6"x6' Pine (with or without knots, up to you, or any other wood for that matter)
Scrap pieces of 1"x4" wood
1" Drywall Screws
1 1/4" Drywall Screws

I used a table saw, but again you might be able to figure out a different way since this project allows for a fair amount of slop.

Since this wasn't a through cut, and was standing the board on end, and after talking with my brother (who is a professional cabinet maker), we came up with this.  I took some 1"x4" board and made a pusher out of it.  I had about 6" of it to the right of the blade, and the rest (maybe 3 feet) to the left.  I attached this to the miter gauge with the 1" screws.  Then I attached a smaller 1"x4" blocker piece to the pusher piece so it would allow me to push my 1"x6" piece against it to make my cuts at 1/2" (or the center of the hole.

I raised my blade up 15/16" and then cut the four holes on the end of the board.  Then I removed the small blocker piece so I could do the center holes.  Then I used the fence with a scrap board pushed up against it that I could remove after clamping down the 1"x6" shelf board.  This way the shelf board would move freely and there was no risk of binding.
