Has anyone out there had any experience with a loose aft canopy hinge on a Discus B? I am working with the owner of his Discus and the aft hinge is noticeably loose as it sits in the frame.

Details from Schempp Hirth are a bit vague with respect to the replacement hinge which the owner has purchased.

Specifically, I require details on how to excavate the cavity around the hinge and then what weight of carbon fibre cloth is used to overlay the hinge on the outside of the frame.

cheers
