Just some thoughts on the legs of the "A" frame getting stuck at the critical moment. I have always envised the legs of the "A" frame being placed in a sort of a timber trough (Greased) so that as the rope burns through the legs slide away freely. To work properly the "A" frame must be perfectly plumb, then the whole thing collapses out of the way.
