The Anatomy of a Shoulder Plane
A shoulder plane is a versatile tool that assembles some parts to act as one. First is the flat sole. The bottom of the tool is called the sole which is mainly made of cast iron or steel. The front of the sole is called the toe and the rear of it is called the heel. The opening where the cutting blade comes out is called the mouth or throat of the tool. Up above the body of the plane, there is a lever cap with a pivoting knob and a lever cap wheel. There is also a depth adjustment knob, toe adjustment screws, and set screws for better flexibility.
Take Proper Care of Your Shoulder Plane
For better workability and a longer lifespan, you should take proper care of your tool. After each use, wipe out the planes with oil. This will resist rusting on the plane. You can store the oil rag in a secure place and the oil on it be saturated so that you can use this rag for cleaning without adding oil again. This tactic will help you to use your purchased oil economically.
In case the planes become rusty, you can use Sandflex block to remove this deadly enemy of metal. For long-term usage, the shiny antique parts may become matt. Use sunshine polishing claws to bring back the shine.
