I figured I could make it by myself. We already had many old used tires, so all I needed was the hardware to attach the tires. "This will be easy" or so I thought. I talked to my husband about my plan & he was not so keen on helping me in the task of building the wall - I guess it is a pain to drill through tires & so on. But I was not about to give up on the idea.
After some thinking & rummaging I figured out a way to make the tire climbing wall all by myself & it is not permanent, so if at any time I do decide to add on to the swing set & need to remove the tires I can ;)
Here is my little monkey man climbing up the wall - I'd say it is a success and took me about 15 minutes to accomplish!
