Help: Pallet Woody

I'm planning on buding a training wall but I'm low on resources as my location leaves me a bit restricted. I have several pallets and will be getting more. Anyone out there have some good design plans for a basic woody made of pallets?

Pallets are often made with low quality wood and are held together with little more than staples. I'm not sure you will have much luck with this endeavor, since I don't think the wood nor the wood fasteners can handle the load of someone hanging from them.

The wood is by far the cheapest part of the wall. Filling out with holds of where you'll spend most of the money.

Some pallets are made out of oak.

ScottR: it's understood that the nails used wouldn't hold my weight. That's why it will be re-enforced with wood screws (2ea at minimum) at every attachment point. After that, I think the wood will hold.

Really cool idea! Let us know how it works out - but I think it's a good point that the wood is the cheap part
