Hello,
I am in the midst of building an 11x14 camera (god knows who planted this crazy idea into my brain). I've got some basic parts done, among them a base board and a slider plate as a lens carrier.
My first idea was to use rails from a drawer as a sliding mechanism when moving the plate back and forth while focusing. However, they don't seem rigid / stable enough at 400mm extension.
A simple option that comes to mind is are beams with a groove mounted left / right and a tongue on the base board (like Pali did on his 11x14).
On ebay I found rather cheap linear bearings (for building e.g. 3D printers or CNC machines) like this.
Has someone tried some of those for the above purpose or in general and can report about stability / durability?
Any other ideas ?
Many thanks,
Lars
