I took an approach similar to Mike Gamble's, except I just did it with a 1 foot
long drill bit. It is easily flexible enough to make it possible to drill at
right angles to the W18's at any height you want. You could easily drill all
the way down flush with the bottom surface if you needed to. It works great
because it is flexible enough to do the job, and rigid enough to not wobble.
