But- oh, what happened! First this- and then this! (apologies to H.A. Rey and Curious George)

For some time, two legs of the high stand were tipping inwards.  I had tried to re-enforce them, but it seemed to be getting worse.

I had real concern that as the weight of the hives increased over the next few months as the bees stored honey that the stand might collapse.  This, of course, would not be a good thing.  I decided that I had to take the hives off the stand and do a proper repair.
First step: get the hives off the stand.  I took the table that had held Olea's hive and placed it in front.  The ground was uneven so I used rocks to try to level and stead the table.
Next step:  lift the hives off the stand and onto the table.  I had (cleverly) measured the table beforehand and knew that the hive had to hang over the side about a half-inch.  I smoked the bees, removed the super and top box, lifted the bottom board and box onto the table and then reassembled the hive.  This went pretty smoothly.

Then it was time to fix the stand.  I had envisioned the process and gone to the hardware store to pick up the angle irons.  Naturally I had not examined the structure first.

As you can see, there is no way this brace would go on the stand leg.  So I removed the old braces and straightened those that were bent.  I unscrewed the legs and chiseled off the old glue.  I then reassembled it , but put the legs on the outside instead so that I would not be putting the screws into the old holes.
When I tried to put the stand on the bricks, it did not fit.  I realized I had moved the legs further apart and so and to replace the bricks on which they rested. 

The bricks in their original position

I figured I should also reorient the stand a bit so I would have more room behind it.  I had to leave one brick where it was, so using it as a pivot point I moved the other three bricks angling the stand away from the fence.  I lowered and adjusted all the screens (that guard the oil cans) and placed the stand.

Now I had to put the hives back onto the stand.  But- oh....
I took the super off of #2 and noted that the table tilted a bit.  I looked at the legs and it looked like there was enough support. Then I took off the top box and...
The table tilted and #1 tilted and fell off onto its side.  Just what this whole process had meant to prevent!
Angry bees everywhere!  Good thing I had my veil on.  What to do?  I thought I should get the hive assembled on the stand as quickly as possible.  I hustled over, put the bottom board onto the frame and then the brood boxes and the super.  There were a lot of bees on the ground in the dry creek bed and on the table.  I looked and looked for the queen.  Was she still in the hive or not?  I looked and looked again and again.  I never did see her on the ground so I assume she stayed in the hive.
Now I wanted to make it easier for the bees to get back into the hive, so I placed some boards for ramps.

Note the clumps of bees in the dry creek bed

I still had not put #2 back together.  So I took care of that, looked again for the queen and rearranged the boards.

I took this picture from a distance without protection

When it was all done I went to take off the bee jacket.  There still 3-4 soldier bees attacking me even when I was back at the shed.  I swatted them.  I may have gotten one superficial sting on the inside of my left arm; pretty good protection, I'd say.
In retrospect, I should have handled things a bit differently.  (After the hive had fallen, that is.  Obviously I should have been more careful about the unstable table.)  My main concern was that the queen may have been ejected from the hive.  It probably would have been better to just let the boxes lie there for a while.  Any bees on the ground would crawl back in, the queen as well.  I will know better what to do the next time a hive falls over.
