Kerfing Plane Kit for Stanley No 50 Light Plough Plane

After much testing and redesign to improve functionality and reduce cost, the Loon Lake Tool Works Kerfing Plane Kit for the Stanley No 50 Light Plough Plane is ready! The three components in the kit will convert nearly any Stanley No 50 into a kerfing plane used to prepare lumber for resawing with a rip handsaw. A shallow kerf cut into all four sides of the board will encourage the saw to follow the cut without the need to constantly check on the whereabouts of the saw blade, drastically improving the quality of the cut, while reducing sawing time and effort.

The kit has been checked for fitment on most of the versions made after 1900. It will work on any model that has nickel plating. It will NOT work on the Type 1 model, which can be identified by the black Japanned finish. This model has a shorter fence that will not properly guide the kerfing blade. Stanley did revert to a wartime Japanned finish for a short period in the early 1940s. The kit will work fine on this one too.

Absolutely no permanent modifications are required to attach the components to the plane. On later models equipped with the cutter adjustment lever, the lever, screw, and nut must be removed so that the blade sits flat against the body of the plane. Each kit comes with complete instructions to install and adjust the components on your plane.

The progressively-toothed rip saw blade slides over the fence rods and is held straight by a stainless steel backing plate. Both pieces are sandwiched between the body of the plane and the sliding section, which uses the original wing nut to hold everything secure. The original fence is used to set the location of the cut on the edge of the board. The new depth stop with a longer rod is used to set the total depth of cut.

Note: this purchase is for the three components in the kit only. A plane is not included. You must supply that.

Note: Thanks to an astute customer, I recently learned that the depth stop may not work on some Stanley No 50 planes that has 'Made in England' on the casting. So far, I have not been able to replicate this issue. I purchased an example of this plane and the kit fit fine. If you should have trouble with fitment on your plane, please contact me with more information on the plane and when it was made.
