Allright----I need someone to educate me a little. On a purchased "peep mirror", there is a flange that wraps around the door edge or rain gutter edge, with a set screw or 2 set screws in it to clamp on the door edge or rain gutter edge. Can somebody let me know how that "flange" attaches to the arm of the mirror? I spoke to Davyj at Niagara Falls yesterday and he said that he has a peep mirror on which that "flange" is attached to the peep mirror arm with a countersunk (flathead) screw. If this is so, I should be able to buy a set of peep mirors, unscrew the "flange" section, and make my own rectangular adapter plate that screws onto the end of the peep mirror arm in its place. Then I could drill through the ends of this rectangular adapter plate and end up with something very cloae to my solid model, which could then be screwed to the outside of my window posts.----I thought that "flange" was cast right into the metal which the peep mirror arm was made. I don't want to use "swan neck" mirrors for this application, as they don't have the correct profile for use as a "peep" mirror.
