So originally I was planning on using the harsh environment plastic piano hinges from Mcmaster Carr for both the hatch and my door. However, I'm now wondering what others have done. What about simple gate hinges? Could they work for both? I've seen pond liners used to seal the gap on the hatch, what else would work or has been done?
I can't say I have any great reasons for not ordering the plastic hinge, I just want to see the other methods I guess.
