I just started working on a new technique for making vessels that seal.
Turning threads in vessels is certainly a skill as well as an art form, but sometimes the movement of wood prevents good seals due to poor thread engagement.
I wanted to make a humidor so I started modeling ways of using PVC fittings for the closures.
This prototype use a staved design, made of pine. Its threads come from a 5 inch pvc threaded pipe coupling. The top has a lens from an old big screen TV. The inside will be veneered with Spanish cedar. Maybe some chip carving as well ......
Below are pictures of my progress. I will keep this site updated.
The workspace where the components were modeled.
The assembly notice the PVC threads and the lens in the top.
