This is a copper top hall table that I made in a class with David Marks at the Mark Adams School of Woodworking. I know there were a couple other LJs in the class and I am curious to see how their tops turned out..so if your out there post pictures so we can see. The table frame, stretchers and legs are walnut. The “feet” are wenge. What I went to learn about was David’s patination process for the top. The top is a copper sheet that was epoxied to a 1/2” piece of plwood which we spent a fair amount of time precisely fitting to the walnut framed of the top. Once the plywood was fitted, then we roughed up the back of the copper sheet with a coarse grinder disk, applied epoxy and put it in a vacuum press for clamping. After it had cured in the press then we trimmed the majority of the excess copper overhanging the plywood off on the bandsaw and the rest was trimmed up with a flush cutting bit in a router table. The patination process was incredibly interesting and consisted of applying resist materials of all sorts (only your imagination was the limit), then spraying the panel with David’s chemical cocktail, follwed by fuming in an outdoor tent to accelerate the chemical reactions overnight. I simply used sand as the resist on my panel and it was interesting to see the result evolve as I removed the sand. After cleanup the panel was protected with a coat of Renaissance wax. We got our tables almost finished during the week of the class, but not quite. I brought mine home and applied a coat of General Finishes Seal-aCell clear followed by serveral coats of General Finishes Oil/Urethane gloss and then one coat of General Finishes Oil/Urethance Semi-Gloss.
