This was a fun project. I have restored many planes before. This is the first corrugated plane that I have. It was given to me by a colleagure of mine, who got it from his grandfather. The plane was fine, just dirty. All the parts were there and they were in good shape. I replaced the blade with a Hock O2 blade. I ended up flattening the sole so that I can take a shaving of a thou of an inch. I recalled that some of my other planes do not produce a shaving that thin. Now, the challenge is on.
