Lends itself highly to the type of modular structures proposed by the Center for Maximum Potential Building Systems - look for GreenForms at http://cmpbs.org/flash/download.htm .

Lends itself highly for flex fab production, especially kits. Fabrication is absolutely simple - after metal is cut - only a drill press is required. Zero welds in structure, with minor welding for motor attachments. DfD, lifetime design. Driven by a hydraulic motor powered from tractor hydraulics.

We are still narrowing down an option for the sawmill. We are considering a chainsaw mill, and here are some [[comments on multipurpose sawmills]]

'''Update Dec. 2, 2008:''' Based on a [http://openfarmtech.org/weblog/?p=407#comments comment from our blog], we decided to pursue a circular blade mill, one like the [http://www.mobilemfg.com Mobile Dimensions Saw].

'''Jan 2009 developments:'''

'''Jan. 2, 09:'''
We decided that the MDS design looks pretty straightforward and that it should be used as the base for the OS sawmill. http://www.mobilemfg.com/

Looked into space frames like the MDS frame. http://en.wikipedia.org/wiki/Space_frame

Read about trusses. http://en.wikipedia.org/wiki/Truss

Need to learn the calculations for materials.

Need to contact Ben and ask questions about the MDS and sawmill.

Where can blades be bought from?

'''Jan. 4, 09:'''

We have narrowed down the design to something similar to the MDS. The current prototype is a dimensional sawmill. In a dimensional sawmill the log is stationary while the blades and motors move. They have 3 circular saw blades: one main vertical blade, and 2 smaller horizontal blades. They cut a whole piece of lumber, like a 2 inch by 4 inch board, in each pass.

A space frame (for stability) on two 'I' beams for x and y axis movements, a chassis surrounding the space frame with bearings to grip it on all sides, a vertical plate or beams on the chassis with another plate attached with bearings and adjusted vertically with a pulley for the z axis, the MDS like saws are mounted on the vertically moving plate and powered with hydraulic motors and pulleys to get the correct RPMs.

Could the saw assembly use a swing blade system for reduced cost? It would have to be stable though.
