| 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].

| 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.

| Oct 2008: We are still narrowing down an option for the sawmill. We are considering a chainsaw mill, and here are some [[comments on multipurpose sawmills]]

| | *[[Sawmill - Design Rationale]] |
| 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/
| | *[[Sawmill Design]] |
| Looked into space frames like the MDS frame. http://en.wikipedia.org/wiki/Space_frame
| | *[[Sawmill Analysis]] |
| Read about trusses. http://en.wikipedia.org/wiki/Truss
| | *[[Sawmill/Research_Development|Research]] |
| We need to get inkscape to make drawings.
| | *[[Sawmill Archive]] |
| Need to learn the calculations for materials.
| | *[[Cut-to-Length Logging]] |
| Need to contact Ben and ask questions about the MDS and sawmill. How much does the MDS cost? How much do the blades cost? (30") Where can blades be bought from?

| Jan. 4, 09:
| | ==Links== |
| We have narrowed down the design to something similar to the MDS 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.
