Zero Point Shelf

Step 5 Drill Holes in Shelves

After cutting the boards to length I used an adjustable hole saw and drilled out the holes in the shelves for the pipe to pass through. I eyeballed the size needed, the pipe just fits through the hole which is what I wanted.

I clamped the shelves together and marked where I wanted the holes on the top shelf. Leaving the shelves clamped together and using a standard bit (1/4" I think) I drilled a hole through all the shelves. I then un-clamped the shelves and used the smaller hole as a guide for the hole saw, so the holes ended up in the same place on all three shelves.

Using the hole placement on the shelves as a guide I marked where the flanges needed to be on the header and footer.
