I’ve been practicing bending my first ukulele sides on my Fox type side bender that I built. I am using a sandwich of ,stainless spring steel slat - white paper , wood. White paper - stainless slat , and the heating blanket on top. The mahogany is spayed with water , I am running the temperature up to 350 deg. F. (186c). Bending and determined set points along the way then holding for 6 minutes, then reduceing the temperatures to
250 f. (122c) and holding for 15 min. to remove any moisture in the wood. I have been successful in bending the sides but I am getting a dark discoloration transferring to the wood. I am allowing the wood to cool & remain in the sandwich overnight
My previous attempts were with non stainless spring steel that had a blue coating on it and the results were the same though more pronounced. I tried to remove as much of the bluing that I could but still had the transfer of color although to a lesser extent, thus the reason for trying the Stainless Spring Steel. . I resorted to wrapping the wet wood in aluminum foil and used the non stainless steel slat and was able to eliminate the discoloration transfer but left wrinkle marks from the foil imprinted on the wood.
Im baffled , what am I missing? Any suggestions would be greatly appreciated.
