Techniques to consider for installing the threaded insert are: Use a 5/16" bolt and double nuts on a drill press. After the pilot hole is drilled in the stock, clamp your stock with a handscrew or a drill press vise and by hand turn the drill press chuck to own the insert into the stock. The drill press will keep the insert square to the stock as it is threaded in.
