Florida Chapter Meeting - Spring 2018

On Saturday/Sunday March 17th and 18th the Florida chapter held it’s Spring 2018 meeting at Joe Kunzman’s shop in Lake Helen, FL; just north of Orlando. Each spring the chapter invites a guest speaker from the woodworking community to conduct a hands-on seminar. Tod Herrli conducted a 2-day seminar on the construction of side escapement wood hand planes. Each participant selected the profile of the plane (hollows, rounds, round-overs, thumbnails, etc.) that they were to build.

The blank plane irons were cut from OI ground flat steel stock 1/8” thick. With the blank inserted into the plane body, the profile on the sole is scribed onto the blank iron. Then the profile is cut into the blank on a series of grinding wheels equipped with flat and rounded profile stones. The iron profile is refined until it exactly matches the sole by repeated comparisons with the sole and additional grinding. Any adjustments to the mortise cut in the plane body are made at this time with a plane float.

 The plane iron was then heat treated using two map gas torches commonly used for household plumbing. The red-hot iron is quenched in common cooking oil found in the kitchen. Lastly it is annealed in an oven for one hour at 450-degrees.
