pick something simple then. A small router, dremel, various different hand and stand up sanders, scrapers, bits, sanding pads, inletting black and then the joy of finishing it. That doesn't count the tooling to do the recoil pad, set the sling swivels, forened, or esteucheon caps. Have you thought about the wood finish or checkering. If it sounds like a lot of work that is because it is.
