Hello. I want to show all the new case I built for my W5. It is made with a combination of stained walnut and sycamore wood . For its design and construction has been used lutheria own techniques. It is designed in the same maner as a luthier build a stringed instrument. It consists of 4mm laminated and curved wood side frames and front and rear racks with spigots. This construction results in a very strong while light box. In dyeing and varnish process, are also violin maker materials and techniques used. Dyes and coating mixtures are based on natural oils and their application is based on very thin layers with wrist varnishing cotton cloth and one week minimal dryin time between coats. The hinges and latches are own designs, machined from brass and then gold plated. As for aesthetics ( shape and color) , it is a matter of personal preference . In this particular issue , I left a little advice as I recognize that I have more mechanical than artistic talent . drawer for the winding key.
