Haley Smith – Surface Finishing
A group of nine CMW members attended a hands-on class with Harley Smith Sunday August 21, 2011. The attendees were as follows: Paul Andrews, Charles Harris, Norm Lentz, Dick Miller, Dennis Piper, John Stroud, Tom Zumbach, Marti Royo and Kevin Brown. The class featured several areas of wood finishing techniques, bleaching, scorching and painting using the wood as the canvas.
The bleaching process was demonstrated using many different types of wood and Klean Strip two part wood bleaching product, which is available at Woodcraft Stores. This wood bleaching process was performed over a six hour period. In some cases the results were dramatic. Examples of this were Mahogany, Purple Heart, and walnut. Safety was of primary importance to Haley, she had the students wear nytril gloves and face shields during the actual application of the bleaching product to the wood. After completion of each step all the brushes were neutralize with two parts water and one part of white vinegar. At the end of this demonstration all the woods and brushes were neutralized.
The scorching process was performed with Bernzomatic type torches. These torches are available at Home Depot for approximately $25.00 and at Harbor Freight for $10.00 both of these torches worked well. A dried piece of Ash (8” X 2”) was used for this finishing process (piece must be raw). Course grained woods work better for this type surface finishing. The piece was trued and sanded to a 220 finish. The face shields were used by all students during all the turning. After the truing was completed the wood was wire brushed with a file cleaning brush at an angle of 45 degrees beginning at the center and completing at the rim of the piece. The piece was then scorched with the torches and allowed to cool. When the piece was cooled two coats of Krylon Matt 1311 was applied with a wait of two minutes between coats, this was done because the oil process was much too long for this class. The normal process was to use clear Danish Oil and allow to dry 24-48 hours depending upon the climate. The scorched area of the pieces was lightly cut using a parting tool. Many different designs were displayed by the students during this phase of the process. Some were geometric and others were figurative.
The equipment used during the design phase was Dremel Tools, WeCheer, and Foredam. One tool was pneumatic. Burrs concave and convex of many different sizes were used. Acrylic Paints were also used for the designs. The burrs were purchased at Rio Grande. The paints were acrylic by Liquitex.
