New hive stands

I was not satisfied with my old hive stands for two reasons.  Firstly, I was uncertain about their weight bearing capacity.  Secondly, in order to keep the ants out, the legs were in cans holding motor oil.  Bees would get into the oil, when it rained the water/oil mix was disgusting, oil would leak or spill into the soil and also soak into and up the hive stand legs. 
At the UC Davis apiary, the hive stand legs were metal pipes and they kept the ants out with Tanglefoot  protected from dust and bees by upside down cans.  I decided to replace my old stands with ones similar to those at Davis.
I decided to use 2x4's and some sort of pipe for legs.  Initially I planned on bolting the legs to the wood, but then realized it would be better and more aesthetic to bore holes in the frame for the legs.
I found some inexpensive electrical conduit pipe at Home Depot.

Pipes and wood before cutting

I found pvc end caps for the ends of the pipe, lag screws to hold the wood together and old tomato cans to protect the tangle foot.

Parts ready for assembly (not all wood or cans shown)

I had to be careful to line up the pilot holes for the lag screws and had only one small error.

An assembled stand, sans cans

I put the cans onto the legs using duct tape to hold the loose ones in place.  Then I painted them with spray on enamel.

A finished hive stand

Today, with the good help of Mihir, after putting Tanglefoot onto the pipe, the old double hive stand was replaced.

Clean up the old hive

I have finished the dismantling and clean-up of the defunct hive #3.  With the use of the escape board, I took off box I had combined with #2. I took 4 frames of newish drawn comb from that box and replaced 4 frames with old wax in the top brood box. 
I then spent a couple of days of scraping propolis and burr comb from all the frames and scraping the old wax off the foundation.  I cleaned and repaired the boxes,
Now my shed is full of deep and medium boxes, plastic garbage bags with drawn comb and lots of empty frames. 
I have started building the new hive stands.  My drill press is inadequate for making the necessary holes in the pipes, so today I went by the Cabrillo College tool shop.  The manager there said he would drill the holes for me next week after finals there are done.  Pictures will be forthcoming.
