In hopes that you can learn from my failures...

... or at least get a good laugh... let's look at that first.
I marked the first block after spending over an hour laying it out, then tossing the first overly complicated layout and then going with a simple 1/2" block out.
(Turns out the 1/2" blocks were TOO close, as we'll soon see.

I spent the next HOUR drilling the dang block, cursing the first 1/4" forstner bit for it's failures.. and using a standard 1/4" bit which wandered and danced.

I found out the 1/2" spacing didn't work when the closely spaced holes caused the material between the holes to fly up into the air, laughing as it flew off into space, crying Free, free...

Miss Tina, loyal as she is... said, "It's just a tool rack... use it anyway."
Ah.... the holes didn't work as they seemed to SHRINK..
Nothing wanted to go right.
So, I came in and sat down to rest... WAY too much time in the shop this morning. I had lunch and watched an old movie.
Then, because I can't STAND to lose...
Tried again.
This time I cheated. I copied the layout of the top of the existing rack. Doubled the size, and used IT as my pattern.
Sigh... the start didn't bode well. The cedar piece was warped. No matter, I found a nice DRY piece of oak, and cut that but refined the design. I used the same design as the plastic rack, just enlarged it.

(Ah, cheating again.)
Taped the two pieces, top and bottom together and CAREFULLY taped the pattern in place.

I punched the center of each hole, cut the pattern away but left the two pieces taped, and DRILLED.
After sanding away any roughness, I glued the sides in place, clamped the assembly and left it to dry overnight.
THIS might just work.

In the morning? More sanding, final cleaning up of the edges, apply finish and done.
After all, it's just a tool rack.
