Lightening Holes
I've been asked how I'm cutting such nice neat lightening holes. I use a set of forstner bits, they don't chew up the wood like a large diameter drill bit...



Used with a drill-press they produce a nice clean hole (a hand drill will work too). Be sure to place a piece of scrap wood underneath what you're cutting. That greatly reduces splintering when the bit exits the other side of the wood...
