When you make a plane you become fully informed on the how's and
why's of plane design and performance.
Photos in this post are of a little coffin smoother I made
several years ago. Since I made the subject plane I have made at
least a dozen more and with each one I have learned from
I suggest for your first plane buy or borrow a wooden plane and
simply copy it in detail.
The little smoother was born after a
woodworker friend of mine had a fire in his shop which destroyed
many old tools and charred a bunch more. He gave me the scorched
plane from which this one was copied.
It was craftsman made with mismatched iron and cap iron. The
iron and cap iron came from the original donor plane.
Fortunately the fire did not get hot enough to anneal the steel.
