| Sawmill - highly versatile and valuable lumber if woodlot is available - or lumber may be bought from neighbors. Decentralized sawmilling may obviate clear-cut lumber companies in a new economy. Many uses. Flex fab opportunity. 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.
| | A sawmill converts felled logs from trees into green wood lumbar. As a piece of the [[GVCS]], it unlocks a range of well-established wood construction techniques. |
|
| |
|
| As a first attempt at a robust and replicable sawmill, we are proposing a chainsaw mill, like a Logosol, with a 25 hp hydraulic motor.
| | To convert the green wood into finished dried lumber the cut boards are either [[kiln| air-dried]] or fired in a [[kiln]]. |

| '''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].

| '''Update Dec. 7, 2008:''' It looks like the MDS blade design is able to rotate both ways, the circles have teeth on each end to cut either way.

| We have a hydraulically-driven PTO motor as a start. It will be powered by [[LifeTrac]]. All hoses are already available - it is part of our flexible open source tractor infrastructure. Here are the motor specifications, from Surpluscenter.com:

| '''Note''': Since we have 3600 PSI available, we can run 2 of these motors in series to match available power more closely.
