I found the plans here:
and altered them slightly for my own means.
Total cost is around $20.
Step 1: Measure It Out
I copied and blew up the dimensions template, printed it out, and traced it onto the board to make the first piece that would act as the template for the rest of them. You could also just measure it out by hand on the board as well.
Step 2: Drill the Holes and Cut Them Out
In total, I measured and cut out 12 of these holders and cut them out with my jigsaw, sanding each down to a 120 grit finish (doesn't have to be perfectly smooth, just sans splinters with no sharp edges).
Step 3: Measure Out the Placements and Pilot Drill
I used 1-1/4" wood screws to attach the holders to the board, so I drilled 3/16" pilot holes (1/8" works too), spaced symmetrically 1-1/2" apart on each line of the zig-zag. To be on the safe side, I counter-bored the holes on the back of the board (1/4" bit, 1/4" deep), so that there wouldn't be any chance of the wood cracking.
I then clamped each holder individually on top of one of the lines, with a dab of wood glue in the middle, and drilled the pilot holes through the back of the board about 1/2" into the holder. After the pilot holes, I screwed the wood screws into the two holes.
I then did the same thing to the rest of the holders, starting from one end to the other.
Step 4: Route the Hanging Holes
The way to make the hanging holes, is first drilling a hole slightly bigger than the hanging bolt/screw head, about half way through the board. Then use a specific router bit that cuts an upside-down T slot that allows a screw head to fit into the slot.
I made two of these spaced about 2 feet apart (symmetrically again).
If you have any better ways to make these hanging holes, please share.
Step 5: Everything Put Together
The bottle spacing looks a little tight, but the angle offset looks pretty good. I even pushed down on each bottle, and the wood showed no signs of give.
First I primed it with generic primer (two coats) and then painted it (two coats again). (all from Home Depot, each can around $4)
Note: painting this by hand would be a pain, so I was advised to use primer and paint from aerosol cans, which leave a more even level of paint/primer without all the brush marks.
Step 7: Mounted and Hung
For installing plastic anchors into the wall, drill a hole slightly smaller than the anchors base diameter, hammer the anchor into the wall, and screw the screw into the anchor up till the anchor hole's depth.
For this project, I definitely recommend oak, anything weaker bears the chance of cracking or breaking, and you don't want wine bottles falling all over the place. This wine rack has been hanging for about 10 months, and it hasn't broken yet.
A last optional step is to apply an enamel to make the wine rack shiny (some paints even come with the enamel in them).
