Ray,
Notice the rings that loop around the end grabs and operating lever. Lift the rings and the weight of the load will open the doors.
I see the rings. What puzzles me is the hinge or bracket that holds the bar in place, at each end of the car. It looks to me like it wraps completely around the bar, preventing movement. Or does it only go half way around, acting as a catch?
Ray,
The end steel bracket is held in place with rivets and the bar pivots in the hole at the bottom. The bar is actually a lever. There are "stops" in the middle of the bar under the door that hold the doors shut. When the rings are lifted, it releases the bar and said bar pivots in the hole. It rorates and allows those two stops to rotate along with the bar (they are affixed to it), thus releasing the door. I think you are trying to make it more complex than it really is.
Cheers,
Tom
Incidently, these car kits are now on sale until the run is gone.
