Sorry about changing the rules on you

This may be a better dealie . . .

I just took a club and held it against the door. Opened and closed the door 2 feet back 2 feet through . . . This would certainly qualify as Horizontal Hinging no? There ain't a whole lot of action going on with that clubface. It is closing without question. BUT the toe ain't slammin' shut like a screen door in a trailer park during a tornado.

At least for me that was an education . . . My version of Horizontal Hinging was FOR SURE Swivel and add a Turned Left Hand to the mix . . . I'm deeeeeeep in the woods where the elephants go to die.

Bucket ,the door is reflecting the hinge action -but not on an inclined plane
But the closing only motion is the same.It's got to close from "on plane" at the start of release,to square at separation -so depending how late you release,it may have to close 90* in -say-4 feet. 22.5* per foot!
