In this instructable I show how I designed and built a climbing wall in my garage for relatively cheap. To view this project and some other pretty cool ones I haven't had time to transcribe over to instructables visit my site mechanicallyinclined.net
Of course every garage varies so my design probably couldn't be copied exactly but hopefully showing how I did will show all the basic concepts behind building a wall and give you a good idea on how to go about this large undertaking should you choose to do so. The total cost of the project was under $400 (that includes holds so if you made your own holds it would be ~220$) and is well worth the investment. An added bonus is the wall has a door that can be opened so it doubles as extra storage space. (or if you dont need storage space but have kids (or you're a kid yourself) you could use the inside as a pretty awesome fort). It really is up to your imagination. But without further adieu we will delve into the finer details of climbing wall design & construction.
