I don't. I was more motivated to get it done. Stopping for photos is for people who have more patience than me.
The instructions are pretty good and really it is removing the screw bolts that hold the rails, dropping the rails to the floor which is a two person job and replacing the trolleys with the slot trolleys. The instructions do show how to set up the chains. Then it is remounting the rails on the wall. Another two person job. The drive shaft has a set screw that locks it in place. That is loosened and the shaft slid in so that it can be removed from the opposite wall rails (I think. I am going by memory here). Then it is a repeat on the other side rails. You just have to make sure that you pay close attention to the chain guides and which way the come off. That is explained in the paperwork. I did not on the first one and when I got it up on the wall and checked the travel, it was going one way on one side and the opposite direction on the other. I had to take it down and redo it. There is not enough space between the bottom of the rails and floor of the garage to leave the rails on the wall to work on them.
One item that was not covered anywhere, and it took some thought to solve, was that the slot bracket that replaces the one that is on the rail and holding the bunk to the trolley pops out of the slots in the trolley when you lift the bunk to unlatch and drop it. Nowhere was there an explanation on how to prevent that because otherwise the entire bunk can come out and drop to the floor or on someone. There is a hole just above the slot in the trolley, where the bunk support arm is inserted. I had several screw bolts left over from where the rail attaches to the bottom of the bunk. I used one of those bolts in each of the holes on each trolley and it locked the bunk to the rails. I told the people at HappiJack about this and got an "oh, yeah, that's what we do." It is not mentioned anywhere in the instructions.
Oh, and the other two person job is that the top bunk has to come off to get the rails off of the wall. My wife is little but she is strong
