Decided I need to get my finger out if I'm to have a new camera for Pinhole Day, so made a start this evening. The plan is a 5x4 made from wood, with a pinhole to image plane distance of around 100mm.
Some bits of wood...
It's all 12mm thick oak, from a couple of offcuts. The sides, top and bottom are cut from a bit 95mm wide, and the front from a bit 145mm wide. The rebates are all 6x6mm, apart from the front which is 12mm wide and 4mm deep. The plain edges that can be seen on the bits here will butt against the rebated surface on the front - the idea is to try and get the front panel a bit further from the film plane. There are two tripod bushes, made using tee nuts with the correct thread. The visible one is in the left-hand side panel, and there's another in the base. There will be internal covers over these to prevent light leaking in.
The bits loosely put together to get an idea of how it will look...
More 6x6mm rebates on the top, bottom and left-hand edges to make light traps around the film holder, with the right-hand side cut flush. The little ridge on the film holder lands inboard of this part, so the thin strip will be used to extend the flush surface inwards, and a groove cut for the ridge to light-trap the fourth edge.
The front has 'left' written on it to ensure it's oriented correctly when glued up because the centre of the image is slightly offset (6mm to the right). The centre has been marked, but no drilling yet for the pinhole.
