The front standard rise and fall will be incorporated into slots in the front rather than the vertical arms This will also allow tilt.
Like this: horseman.jpg Although that does have longer stays, but I can easily make some like that to try out.
Putting the rise and fall into the front is a cunning plan to reduce the length of the vertical arms. I have been studying the Wista Field and Tachihara cameras and noticed that they differ in where the hinge is located and because of that, the position of the base plate when folded.
The Wista puts the side stays to the front which means that when the camera is folded up, the base plate is pushed all the way to the back and the front is tilted forward to horizontal.
With the Tachihara it's the other way round. When it is folded, the front is moved as far forward as possible and the front folded back to horizontal. The front rotates in the opposite direction so that in the folded state, it is upside down between the arms.
In both cases the front needs to be moved so it is centred for folding. This requires the front to be dropped down. However, in the Tachihara style of mechanism, as the front is reversed for folding, this is actually rise when the camera is in its working position meaning that I don't have to allow for an excessive amount of fall as I would if using the Wista system.
The nice thing about having the use of a CNC router is that I can easily make both versions and try them out!
I actually quite like the look of this black fibre glass material. It looks a bit like carbon fibre (looks much better in real life than the pictures). I might be tempted to keep it like this. It does cost about £70 for a 12" x 18" sheet though. I'm using offcuts at work at the moment.
