Known in the climbing community as a "woody", a (usually indoor) climbing wall constructed with plywood and bolted on holds, isn't too difficult to make. We made one in a basement for about seventy dollars and change (which we raised by selling other peoples' things on craigslist).
Things you'll need:
- Some 3/4" plywood
- Some 2x4s (or 2x6 or 2x8) for framing and such
- 2" (or so) wood/drywall screws
- 3/8" t-nuts
- 3/8" hex cap bolts
- Drill, hammer
- Something soft to work as a crash-pad
- Beer
The first step is to choose a location. For us, the perfect location also was so cluttered with things, that you couldn't see the floor. So, for two days (and many beers) we cleaned. We carted away junk, created a pile of things to sell, and reorganized things that needed to be kept. In the process, we found many cool treasures.
Besides, indirectly he has a point--most home walls are set back at -15-90 degrees (overhanging.) This one would get boring, fast. But that was his choice--maybe the builder has kids, etc.?
Also, it's a shame the shelf framework was already built. The frame is such an important part of building a home wall, it's as if half the instructable were left out...
Still, he's getting my "They Like It" vote--anyone who includes a 'crack machine' (even a short one) in a home wall rocks (pun intended)...
