I find one of my most versatile tools is my oscillating drill press. It is a Craftsman, but they don't make this model anymore. However, Grizzly makes an identical model that matches my Craftsman exactly. With it I can drill my pin holes accurately and with the sanding drums I can sand my rough cut scales to my drawn outline. Also, using the drums and these plans you can sand your scales to the proper thickness. Very handy
