So let me start with saying I am NEW as in "neva been done befoh" so I hope I am doing things correctly. I have 2 empty hives and I am picking up my packages on April 2nd, so I'm just over 4 weeks away from being a beek!
I went to home depot today with a pencil and a measuring tape. First I came up with the 2 pipes and the T with 10" nipples and the black pipes are 48" long. I'm planning to drive those at least 24"into the ground and also secure them to a vertical board in the garden.
Next I needed the ladder type frame. I made a bunch of measurements and ended up buying 2 pressure treated 2X4s and had the home depot guy cut a 3rd into 5 pieces 17" long. I came home and screwed it all together and I think it is going to work well. The ladder is 20" wide and 96" long. I think I could have 4 hives if I really wanted to, so 2 will fit just fine.
Here is a photo. I laid the pipe & crossbar on the ladder frame so you can see how it will fit when driven into the ground and ladder set on top:
