Mark’s shop was having a low humidity crisis that was slowing down work on the top and back of the instrument until it could be resolved. Despite extensive humidification he was only only able to raise the humidity to 35%. The problem was that his pellet stove heater was drawing combustion air from inside the shop and exhausts it outside. It’s was sucking all the humidity out of the room. Today, Mark added a pipe to bring in some combustion air from outside. It resulted in bringing the shop % RH above 40% so once the wood equilibrates, he can continue to work on the guitar.
In the interim, Mark inlayed a Green Abalone “B” into the Brazilian Rosewood headstock veneer today.
