That's more or less how I've always done it. I just have a full-sized drill press and an adjustable jig. Nice cheap alternative to not having the equipment, though.

The problem with this method is that you need a drill press and a vise. I only have some clamps and a cordless drill.

I'm getting the vibe that you'd rather use perfboard...

Regardless if there are other ways to do it, this is one way that works if you have a drill press.. Perhaps you could use perf board but want your holes spaced differently....
