The walnut bowls shown here were all cut green, dried naturally 2 to 5 days maximum and finished in one day. I’d like to share my experience with this experiment. The large logs I received were so wet that each log weighed at least 150 lbs or more. Stems sticking out the side were green and bent rather than snapped. I began turning the wood within a week. Water oozed out of each cut and covered my face shield during the process. All bowls were mounted once using a 4 screw faceplate. I turned each bowl outside and inside in one night. The process included cutting, scraping, sanding (80 thru 320) and detailing with a Dremel and more sanding, and finally buffing with tripoli and white diamond compound. I used a parting tool at the foot but only made a starting cut. The walnut vessel was cut free-hand using a skill saw.
Each bowl was set aside with faceplate attached, stored in a shaded room in my home for 2 to 5 days max. I remounted the bowl, sanded a second time (120 to 320). I re-cut the rim on one of the bowls. The next morning I applied a sacraficial lacquer coat as needed to remove any visible scratches and parted the bowl at the foot followed by belt and hand sanding and buffing of the bottom. I left the bowls overnight to allow the bottom surface to dry. I then applied two coats of lacquer, sanding each coat with wet 600 grit between coats. This finishing occured over a 1 1/2 hour period. I then applied Formby’s Tung Oil over the lacquer surface, wiped off the excess and immediately buffed out with light pressure using the white diamond buffing wheel. I then did a final buffing using the carnauba wax wheel, again, using very light pressure. The Formby’s finish seemed to act as a lubricant under the white diamond wheel and the lacquer took on a very even finish.
The bowls shown are 11 to 13 inches in diameter. The vessel is 7 1/4×7 1/4 inches.
I then set the bowls aside and observed some minor elongation on the detailed rolled rim bowl and minor surface rippling on the natural edge bowls. The finish has remained as originally applied. The process was experimental but I am amazed at the results and see no evidence of cracking or excessive warping that would make the bowls unpleasing to the eye. It should be kept in mind that I am a fan of rustic design, inherent when you’ve only got 15 months turning under your belt. I realize that the density and type of wood grain impacts ones ability to turn and finish in this manner. I have enough walnut left to turn 5 more medium to large size bowls and see no reason to wait for the wood to age.
