Today I was finishing up getting the barn ready and set up for my new rabbits. One of the things I decided to do was to put my cages (three high stackers, mostly 30x36's, one stack of 30x30's) on wheels. I did this because I have "indoor" and "outdoor" space for the rabbits, and I want to be able to easily move the cages in and out. The outdoor space is a covered porch (barn porch) with field fencing (2x4 I think) on the walls, floor to ceiling) and an extra wide door (so I can carry pans out) that is constructed from wood and is covered with the same fencing. Anyway... as I was figuring out how to attach the wheels, I remember someone asking about how to put wheels on cages recently, so I thought I would detail here how I did it. This was done by me by myself, so it really isn't difficult. Thinking it through was the hard part; doing it was actually really easy :)
Supplies:
Pressure treated 2x2's
Pressure treated 2x4's
Bolts to fit through the holes on your cage legs (bolt length to suite yourself)
Nuts and washers to fit the bolts
Four wheels for each cage (swivel wheels on metal brackets, I used 2-1/2 inch Swivel Casters from Lowe's. Locking casters for the front and non-locking on the back)
Wood Screws to mount the casters (I used Flat Phillips-Zinc 12x1/M5.5x25.4 from Lowe's. These screws have heads that are large enough that you don't have to use washers with them)
Tools:
Drill
Saw
Tape measure
Pencil
Hammer
For a 30x36 cage:
First, cut the 2x2 to fit from leg to leg as in picture. Mine measured 30-1/4 inches. Next, attach the 2x2 to the legs by first drilling a hole in the 2x2, then inserting a bolt through the hole, adding washer and nut to secure. In the picture, you will see that I used two bolts; this is because I drilled an additional hole into my legs, thinking that two bolts would be better. On the other cages I added wheels to, I just used one bolt. (Queen of Overkill! lol) If your bolts have (as mine do) a square beneath the head, you might need to hammer the bolt head into the wood until the head sits flush on the wood). Repeat on other leg. Next, attach 2x2 the same way to the other side of the cage/other two legs. (I neglected to place the washer in my picture below...you can do better
So....next, cut your 2x4 to length, so that it fits, as shown, from 2x2 to 2x2. If you mounted your 2x2 just right, you'll be able to extend your 2x4 a little bit beyond the cage leg, adding to the strength of things. If you're like me, and did not mount your 2x2 just so, you will have to make your 2x4 fit between the legs, as mine does in the picture. Either way, I really think it will be FINE. I am the queen of over-kill lol, liking to make things as secure as possible. But, as my Dad so often points out to me, "It doesn't have to fly"...so either way should be fine;)
Next, place your cage right side up, and slide the 2x4 into place. From the top, (no pictures for this), using two 2-1/2 wood screws per corner, attach the 2x4 to the 2x2. Do this by screwing from the top, through the 2x2, into the 2x4.
Then, flip it upside-down again and attach the wheels/casters. This is where you will use the Flat Phillips 12x1 wood screws with the heads that are larger than the holes in the metal bracket of the wheels. 4 per wheel....git'er done!
Finished product!:) Ready for you to stack one or two more cages (with legs and pan slides) on top!
These roll really well. I was concerned about them being perfectly level, did nothing to insure that they were perfectly level, but they somehow do sit just right;) So...give it a try:) If you have any suggestions to improve the idea or questions, I'd love to hear both/either:):):)
