You've done a good job of connecting these parts. You may run into a small issue when you get your wood and are inletting the trigger plate. Often these plates do not have the same bend as the precarved stock will have, and will either need to be bent to conform to the wood, or the wood needs to be carved exactly like the curve of the plate. Don't attach your back machine screw until you have the stock in hand, and the plate4 inlet. Inlet the plate without the guard in place, without the triggers and springs in place as well. My tutorial goes over this aspect of the build. You should have no difficulty inletting the plate exactly down the centre line of the stock, if you have already drawn that onto the wood.
