JUST A LITTLE LONGER...
I cut 2 Plastic Strips to fit over the 2 Frame Braces, next to them.
Here they are in place. I did this to strengthen the frame before I cut it in half!
I cut the frame at these 4 points because I am going to slide a, 1 inch and 1/8 long, piece of aluminum of tubing over each cut. This will make the frame about 3/4 inch longer!
Here are the aluminum tubes glued in place!
