Steve: Thank you for your input. You are correct in stating that the current stock fasteners are Dzus in style. However, they are, in true Morgan fashion, flimsy in structure, and totally unsuited for their intended use.
I will be installing Camlock 1/4 turn aerospace fasteners as provided by Skybolt Co. They are much more robust in the receptacle and shaft dimensions, as well as in their retaining springs.
I have used these in the construction of experimental aerobatic biplanes; they are also used for production engine cowlings and other aircraft applications. Special tooling is required for installation of the components, but I think that the extra effort is worth it.
I am unable to post photographs, but suffice it to say that I have full confidence in the Skybolt fasteners when entering the aerobatic competition airspace at Vne. (Velocity never exceed).
Planenut: Thank you for your suggestion. I will also follow.
Best regards,
Tom
