Just for interests sake general perusal.
Got this unusual job out of the blue last week.
Client needed an timber ring to house an electronic musical instrument that responds to changing weather conditions to make it's music.
Outside diameter had to be 1880mm, inside dia 1720mm and the thickness had to be at least 100mm.
As I have made a few round windows before using segmented construction, figured that I may as well do the same here.
First step is to make a template for the segments. It must me made as accurately as possible......
DSCF4981.jpg This segment template is for 8 segments per row and the finished item will have 3 rows. So that's 24 segments at 34mm thick. Timber store in town had Tas oak dressed framing 165x35mm so just had to thickness a mm of it.
Bought 2 thin sheets of craftwood and fixed them together on the floor (as I dont have a workbench wide enough) and marked out the inside and outside diameters with a set of trammels. Then started the building up....
DSCF4956.jpgSkew nailed the first segment to the craft wood and then used pinch dogs to clamp the segments end to end and continued skew nailing as I went.
DSCF4957.jpgPut strips of newspaper under the joins to stop the ring sticking to the craftwood. Once the first layer is done it's time to biuld up the second one.
DSCF4958.jpgEach segment on the second row is glued and screwed to the first row with the joints overlapping (a bit like round brick work). Then the 3rd row...
DSCF4960.jpg Once the 3rd row is done it's all over, job done.
DSCF4979.jpg The guys who made the electronic musical instrument that goes in the ring made it in London and dropped in today to make sure everything would fit together (thankfully all was good). The whole assembly is going into the wilderness somewhere for a short time to make it's music for a beer commercial of all things. Then it's off to the Melbourne cup to be in the corporate area of the beer company.
