I got a carvewright machine a few years ago. I haven't played with it in over a year, but I did do a 3d scan of some 1911 grips and successfully carved a set out of walnut. At the time I toyed with the idea of making grips, but it never took off. The biggest issue is that I would need a set of grips for each model of pistol to scan and then replicate. Maybe I'll get of my ass and start a buisness.
