I am back from another productive trip to Marc Adams School of Woodworking. Thank you to everyone for making my stay pleasant, and comfortable, as usual. On this trip, I had the opportunity to make some new friends, and become reacquainted with many old ones. My only regret is that we couldn’t spend more time together. These trips are always so hectic!
As I mentioned previously, I spent a week with Patrick Edwards learning French marquetry technique. We focused on the Boulle process, also known as tarsia a incastro. In it, the various colored veneers are bound together in a packet and cut according to the design. The packet is opened, and the picture assembled by placing the veneer pieces of one species into another. Any voids between pieces are filled with a wood dust and hide glue mastic, nearly imperceptible to the casual observer. This fundamental technique offers the marquetry craftsman the ability to generate multiple copies of a design rapidly.
Cutting takes place using the chevalet de marqueterie, or marquetry “easel”. This uniquely French tool allows the operator to hold the veneer packet vertically at eye-level while guiding a saw along a steel rod adjusted perfectly perpendicular to it. The accuracy is such that a piece taken from the front of the packet fits within the corresponding “hole” in the veneer on the back of the packet. The manually operated saw also offers a greater degree of control than a typical powered scroll saw. Small delicate pieces can be produced which might otherwise be lost in the machine’s vibration.
Once I’ve gotten back on schedule, one of the higher priorities on my to do list will be to tune up my mini-chevalet. My experience this week gives me a better idea of how it should work!
