Yes, the flat hinges work fine, properly installed. And as I said, if that works for you and others, great. If you re-read my first post, I didn't say "Don't use them", I said, "I won't use them". All I am trying to do is help those who want to use the pinned hinges do it properly, based on my past successes (and failures). Granted, my method is very complicated, tedious, and takes a lot of patience. Not to mention the few hours it has taken me to explain it lol......
I think I've covered the system well enough. If anyone is interested in more detail, just PM me. No need to hammer it further here.
It's up to Jerry to decide. I am not trying to influence him, only help him.
