Diamondwood checking problems

I just finished the 4" utility knife I`m making and I had some trouble with the Diamondwood Cocobolo I used for the grips. Every time I drill a hole through it the wood checks a little on one or sometimes both sides. I managed to sand most of it out but a little remains to bug the heck out of me. Any suggestions as to how I can avoid this? I really like the way it came out otherwise. I`ll post pics as soon as I can hook up with my buddy that has a scanner. Marcus
 
MArcus, when you say "check" do you mean a
crack or splintering as the drill bit makes
contact with the top of the material and exits the bottom of material. If the latter, you might try afixing a piece of tape perhaps two or three layers thick on the bottom of the material to avoid "blowing out" the material. The same goes for the top of the material also, although you would obviously have to cut out a hole so you can see where to drill. Just an idea.

I don't know if this would work, but it could be tried out by anyone drilling wood soon. Instead of cutting a hole and trying to align it with the drilled area, as long as you're going to drill through some tape anyway why not try this?

1. Decide and mark exactly where you want to drill. Small mark is more accurate, obviously.
2. take a piece of tape and impale it with a sharp pin. A sewing pin would work; a sharp dart or stiff wire would also do it.
3. Now just put the point of the pin firmly on the mark for the center of the hole-to-be. Even push it in a little if that seems workable. Then slide the tape straight down the pin and adhere it to the wood without moving the pin.

Remove the pin and voila! Now the handle is covered in tape and you have a tiny, perfectly aligned hole to guide your drill precisely. Will this work? Is it worth the trouble?
