I bought a set of Wayne's plans when they first came out, and based my first half dozen Hawken rifles on them. I even filed out a breech and tang, a lock, and triggers using them, and they worked very well. They are made with a draftsman's eye, with radii and mutitudinous dimensions. My set shows a lot of water under the bridge. Followed carefully, they'll give you a very nice S. Hawken rifle.
