Here's what I did. First, I chose how many standard cylinders I wanted to mount. Personally, I decided on 5.
Then I marked where I wanted the locks to be. You can see the pattern in the following pics.
Then I drilled the holes, using the drill bit that was closest to the lock diameter. It turned out to be slightly larger, but it doesn't really matter.
I decided to make one hole larger to accomodate a deadbolt or doorknob.
Then I marked two holes where I wanted my smaller tubular locks and my DOM Cabinet lock to go. Then I drilled these holes.
I made a base for the board, and glued and screwed it on, making sure to countersink the holes so that the screws would sit flush and not protude and cause the base to wobble.
I sanded everything down, and it was done!!
Because the holes are slightly larger than the locks, a push pin down the side of the lock between the lock and the wood will pressure fit them in.
For the Tubular locks, wrapping them in paper and then pushing them in will keep the nice and snug.

Personall, I'm very pleased with it, I especially like the layout, none of the locks get in each others way.
Feel free to post any questions here.
