So this is the Scalefour Society lever frame, in its 'stored' position it just about fits without protruding beyond the backscene at the outer end - the reason thats important is so that the baseboard can be laid on the backscene if reqired. The intent is that there will be a spar that crosses the back, more or less where the ruler is in this photo. Obviously there is no room for fingers to get behind the lever to operate them with the frame in this position.
Here the frame is in the operational position. it only has to move about an inch.
This is whats going on underneath, the two photos show the stored and operational positions. The final conections between rods and levers have not yet been made, they will probably happen a bit lower down, but its better to have too much and trim back again, than cut them too short!
I would really like to operate my new layout with a proper leverframe like this although it may be difficult to arrange all the interlocks for points and signals on different boards.
How are you getting on now with the point actuators and cables now? Does Scalefour Society sell its frames to the profane?
