I've used Bruce's method of v-blocks and a drill press. I also drill two holes; I tighten the nut and determine where I'd like the first hole to be, then I mark for a hole that is not exposed by the slots. That allows for two different positions. Before I drill, I grind away a little of the thread with a Dremel, so I have a flat surface to start with.
