Hi Conrad,
                Have you checked the dag screws, and rear key frame
bedding. I had a SF10 with a similar problem, the rear of the frame was
binding on the treble dag. it turned out that some one had tightened the
glide bolts, forcing the rear of the action upwards when the cheek blocks
were tightened.
Regards Roger
