=Design Contract=



Agreement: This document states the agreement between Larry Dobson, designer, and Marcin Jakubowski, recipient. Dobson will provide detailed plans for a heating system with the following features:
 * A residential-size hot water heater fueled with wood pellets, wood chips and other biomass fuels, able to operate on natural convection flow or fan.
 * Size will heat an insulated building of about 3000sq.ft.
 * Configuration will include gasifier fuel hopper with combustion chamber and heat-exchanger modules integrated into one unit.
 * Gasifier will include manual grate adjustment and rotation for ash-separation at coal-bed, ash-collection with manual removal, and manual air-intake dampers for gasifier and combustor.
 * Atmospheric hot water heater will be of spiral design of sufficient efficiency to allow condensation of moisture from flue gases on low settings and high efficiency.

Special Considerations :


 * Complete set of plans to be completed within two months and made available as an open-source document on http://opensourceecology.org. Dobson will provide:
 * 3D Cad files in a professional CAD package
 * 2D fabrication drawings readable by a custom fabricator
 * Exploded part diagrams and other views to show all parts
 * Notes on fabrication procedure
 * Bill of Materials
 * Sourcing information on parts.

=Overview, Plans, and Drawings=

This is the full submittal as of Dec. 22, 2012, featuring most but not all of the detail drawings. The contract has been extended - Larry Dobson will produce the completed plans by January 31, 2012.





=Completed Design of February 1, 2012=

Here are the gasifier plans: 62 pages of detailed drawings, 15 pix, 11 pages of explanation and instruction, 18 pages of CNC cutout drawings. This represents countless hours of preparation, but I’m sure there will be much discussion and need for further clarification.



Great set of documents, but where are the "3D Cad files in a professional CAD package"? Looks like design was done in IronCAD, maybe?
