Re: Left Tilt or Right Tilt?

>The L-N #140s are very flexible, mult-purpose tools. Not everyone who has one (or two), makes full use of all it's capabilities. Thus some of the confusing, contradictory recommendations. The use that makes handedness important is fitting tenon cheeks. (It is better to use a shoulder plane for fitting tenon shoulders.) For this function, if you are left handed, you need the original #140 with the removable plate on the right side. Even a Stanley without a fence or nicker will work. Using a pair of bench hooks, push the board back and down against them with the right hand, with the tenon pointing to your left, and push the plane with the left hand. if you are right handed, you need the special L-N #140 (a Stanley or MF will NOT work) with the removable plate on the left side. Hold the board against the bench hooks with the left hand, with the tenon pointing to the right, and push the plane with the right hand. Obviously, pulling a #140 that is wrong-handed is inappropriate in this application. Note that when you are doing this, your shoulder plane, which is holding the stile to which you are fitting the rail, is well out of your way at the other end of the bench, but still convenient.
