So, here we are trying to end the yard framing with a flexible piece of plywood hanging out in mid air.
What I did was to place a strong piece of wood under the benchwork for the branch line and clamp it in place. I then hung a piece of 2x4 that I ripped in half from that piece with a clamp/ Then I clamped the flexible plywood to the vertical piece.
You can see this in the first two pictures.
It gives you a good idea of how everything was hanging out in space. Needless to say, we had a few hickups with this Rube Goldberg contraption.
The last series of shots show how the bench work came out.
One last point that I should make. The rear of the framing had a long span to cover as it crossed over the lower yard throat. In order to broidge this, i ripped two 1X4' s from a piece of furniture grade plywood. Then I screwed and glued them togeteher, essentially creating a 1.5 X4 piece of wood that was pretty strong. You can see it in the last two shots on the left side of the framing of the upper yard.
