Binnacle
Several offcuts of 15mm copper water pipe were cut to size to form the body of the binnacle. The compass disk was turned from brass and pivots on a needle. The needle is fixed in a holder, also turned from brass. The holder pivots in a brass gimbal ring on two 1mm dia brass pivots. The gimbal ring is pivoted to the outer body using two similar pivots. Two tiny magnets, 2mm dia and 3mm long fit into holes in the underside of the compass disk. I found that the magnets were attracted to the needle pivot, which prevented the disk from turning. Replacing the needle with the shaft from a map pin solved this problem. I guess the map pin is a non-magnetic stainless steel.
The oil lamp housing was built up from pieces of brass sheet, soldered together. A compass dial was printed and glued to the compass disk. The disk is 9mm in diameter.
I didn't have any large enough brass rod to make the binnacle plinth, but I did have a brass nut from a plumbing fitting. The end of the nut was turned down and parted off to provide the plinth.
The angled photo shows the gimbal in use.
A window was turned from acrylic rod to fit in a brass bezel. Both faces of the acrylic were smoothed with 1200 grit wet and dry and then 'fire polished' to make the window transparent.
The last two photos are to give an idea of the scale. In the last photo, the oil lamp is lit 😉.
