The complexity and the required accuracy of this project is a labor intensive process. Nowadays I understand quit well why these mechanisms where seldom seen compared to the barrels which opened to the side(
http://i40.tinypic.com/ilggtd.jpg) . Quote “Rebuilding these kind of systems require an enormous concentration and experience. When the systems opens to the side, as seen in the picture, the block is perpendicular to the gab in the barrel, this makes it easier to get a tight seal than in the system I am building (the block opens with a circular motion and requires a roundish opening in the barrel).” The mechanism in the picture is a lot easier to build. The project I am making together with Marcus (the client) is much more demanding. This project has given me the chance to relive and understand the atmosphere, the reality and the stress of the original builders and their work. Marcus does live far away from my workplace, but I am convinced that his Dutch heart will understand the work that I do.
For those who are not familiar with this work, I will add examples of the 16th century atmosphere to make you understand this project for the full 100%.
