Created a set of build instructions for the "Material Awareness exercise"
Built the "Material Awareness structure"
- Observations:
  - Material is much bigger and heavier than you would think from the sketchup model
  - Assembly works best if nothing is tightened down until entire structure is assembled
Disassembled structure
Did inventory of 1" bolts and nuts.
Did inventory of hydraulic hoses

Search "Brake valves to control hydraulic motors with over-running loads"

Information on Overcenter Valves:

Interactive video on how hydraulic brake valves work

We need either a drum brake system or a hydraulic brake valve.

Options for drum brake:

Does not fit, but demonstrates that there may less costly options: http://www.surpluscenter.com/item.asp?item=28-1324&catname=

Options for hydraulic brake valve:

Still need to determine price and circuit : http://www.hydrotech-bg.com/common/d_images/src/file/PDF/E4-ACCESSORIES.pdf - See Overcenter valves with brake control
