Thanks for the reply I will see if I can do the thread since they are working panographs I May just turn them off.

Make a little loop of (black) thread between the top and bottom of the pantograph to restrain it at a safe (and more realistic) height.

You can also increase the bridge clearance about a half-inch by removing one truss piece over the bridge entrance farthest from the pivot, but this alone is not enough for the GG1.
