RE: CA Hinges in gassers - Hinge failures
RFW1953,
Are the hinge sheets that you refer to and need cutting to shape the smooth plastic Mylar hinge type?
If yes I understand that the surface of this smooth material is best roughened first with glass paper or a file then smeared with epoxy and mated to the hinge slots forming a secure base about the surrounding wood. CA is then eased across the hinge surface to wick around the epoxy to form a secure housing. When set the hinges are drilled and pinned with cocktail sticks.
The newer furry or hairy type hinge material has a pre-roughened surface similar to hairs and are positioned onto both surfaces then simultaneously CA'd which wicks through the hairs to form a very secure fitting. I would be interested to find out if these latter CA hinges are also failing as some modellers appear to believe that they are without fault.
I'm no expert but I would like to clarify this grey area before fitting these CA hairy type hinges to my latest Spitfire.
Thanks!
