Update for September 25
From the September 23 update - what I think I learned:
1. Using one bolt to connect an open square tube to a joint does not work well
2. It takes time to gather tools and parts to test bolted joints
3. My shed may not look very sturdy, but it will likely do OK for testing up to 500 foot-lbs of torque on bolted joints .. perhaps more ..
For our next test joint ...
The 1.75 inch long 3/4 inch tube that makes up part of the joint will have a hole drilled in each end close to the end. The 9/16 head of the 3/8 bolt should jam against the edge, so the hole should be just under 5/8 from the edge. This should assist with assembly.
The 1.75 inch long 1 inch tube will have similar holes drilled.

These 2 tubes each 1.75 inch long will be bolted to a new 60 inch piece of aluminum tube. The original 'second' 60 inch tube will be bolted to create a joint that looks like the original test joint, but should withstand much more pressure .. I hope.
The new joint will be bolted to 2 new 2 x 4 pieces. These pieces will be lag bolted to the shed at a height of 15 inches, like the September 23 update.
It's raining and it's dark (I got home late ..) so the testing will have to wait until the weekend.
I know this was not much progress .. but smaller chunks should be better than the last marathon update, right?
