While your looking for a blank and rounding up tools you'll need a template for the butt and grip. A commercial metal grip cap from Brownells or MidWay will work for the grip, but, you'll need to make one for the butt. I use 1/8" thick flat steel. A tracing of a butt end of a stock you like will do. Transfer it to the steel and cut and file it out. It's nice if your screw holes in the template are placed properly for the pad you'll use.
