Carpet (amount depends on size of condo)
Cardboard Masonry Tube
Radial Arm Saw (a Table Saw or Circular Saw will work just fine)
Step 1: Cutting and Marking
The cardboard tube that we used was 12 inches wide, so we decided to make the base 20 inches square. We measured it off and marked it with the black marker. We then used the radial arm saw to cut the square. We also marked off the top part of the cat condo, ours was 18 inches by 13 inches. You can make the top part the same as the base if you want, we were using left over wood, and needed to adjust the size a little bit, to make it fit.
Once you have the base and top cut, you need to center your cardboard tube on each of them, and trace around it with the black marker. You can then use the drill, and drill a hole inside of the circle you just traced on both pieces of wood. This will give you a place to start the jigsaw, so that you can cut the circles out, remember to cut the holes a little bit bigger than the tube, because you will have the added thickness of the carpet to go inside of the holes also. The amount of extra you need to cut, will all depend on the thickness of your carpet.
Step 2: Carpeting
Now you are ready to cover the outside of the tube with paste. Lay out a big piece of carpet, enough to cover the tube. Now lay the tube on top of it, and make sure one of the edges of the carpet is straight. You can take the paint brush, and cover the entire tube with the flooring adhesive. Next, start rolling the carpet with the edge of the carpet lined up with the edge of the tube. Once you have the carpet rolled around the tube, put it somewhere to dry for a few hours, or even overnight for best results. Once the adhesive has dried, you can cut the extra carpet away from the tube. Once the tube is covered with carpet, it is time to attach the base.
Step 3: Coming Together
Step 4: More Carpeting
Now you can cover the base and the top with the carpet. You can use the adhesive on these, but you do not have to. Staples will work just as well. Just line the pieces up and tack the edges on the inside and outside, with the staple gun. Next, pull the carpet over the edges of the wood, and tack the carpet to the edges of the wood with staples. Make sure to cut the corners out of the carpet, so you do not have extra on the corners. Now, attach the carpet to the other side of the top piece of wood. This should leave you with all sides covered on the top piece of wood, except for the edges inside the circular hole, and the carpet inside the tube should cover these. This should also leave you with just the top and outside edges of the base covered as well. Do not cover the bottom of the base, because it will sit on the floor.
You can also attach the top peice of wood to the top of the tube, using the same method we used for the base earlier.
You should now have what looks like a giant scratching post.
Step 5: Holes and More Holes
Now that the holes are marked, we are ready to cut them out. Basically, we just used a really sharp utility knife, and kept scoring the carpet on the lines, until it cuts through the carpet and part of the cardboard, and we just kept cutting along those lines, until it was cut all the way through the top layer of carpet and the cardboard, and then we used scissors to cut away the rest of the inside layer of carpet. We did this for all three of the openings we made.
Step 6: Attaching the Shelves
The next thing we did was cut the shelves. This was easy enough, because ours were all 7 inch squares. We used the radial arm saw to cut them. Once they were cut, we cut carpet for them also. We left enough extra carpet that it can cover the outside edges of the wood, just as we did on the base, but on one outside edge, we left enough carpet to cover the bottom of the shelf as well. So we attached the carpet to all sides of the shelf, except for the bottom. Next, we placed the shelf on top of the L brackets that were sticking out of the hole. We pushed the shelf about an inch inside of the hole, to make it a little sturdier. We then drilled holes in the bottom of the shelf, for the brackets, and we attached the brackets to the bottom of the shelf with small screws. Then we took the extra carpet, and pulled it tight against one edge of the shelf and tube, and then in the middle, and then the other edge, and made marks, so that we could cut it in a semi-circular shape. Then we used the staples to attach it to the bottom of the shelf. We repeated these steps for all three shelves.
Step 7: Making It Fun
Step 8: I Think She Likes It, Maybe a Little Too Much!
To add the extra support, it is really simple. We found a small block of wood, and cut to the length we needed to reach from the base to the bottom of the shelf. We covered it with carpet on three sides, by using the staple gun to attach it to the wood. Then we pushed it into place, directly under the shelf, and we put a screw into it from the bottom, through the base. We also put two more screws into it, from the inside of the tube, into the un-carpeted side that is against the tube. The screws bury themselves into the carpet and are not noticeable, so we may actually do this for all of the shelves.
