Turning Boxes...
Hello George,
I use a traditional approach to turning boxes that has proven itself over the long run in terms of dimensional stability with very close/suction fit lids remaining true.
Briefly, I rough turn the boxes from green timber and partially hollow the interior of the top and bottom. The roughed out pieces are then removed from the lathe and taped together at the dovetails with the interior hollow exposed. The date and species is noted on the tape.
The taped roughout is wrapped in a grocery bag (1 -2 wraps depending on the species and moisture content when turned) and allowed to air dry on open wire racks for 1 - 2 years. Most of the boxes I finish turn these days have been drying for about five years before they are completed.
When I'm ready to finish turn the piece, I remove any warp and true the piece up. Once that is done, the piece rests for 24 hours before final turning. There is one additional 24 hour resting phase in the fitting of the top lid as well before it can be completed.
This protocol has been the most reliable for me through the years when working with exotics, so I stick to it. My inlaid boxes can go for several thousand dollars, so I must be very careful to insure my drying and turning protocols do not result in future warranty claims. Take care and all the best to you and yours!
