| A sawmill enables custom lumber production on site using locally available timber. We are particularly interested in a ''dimensional sawmill''. A dimensional sawmill is a circular blade sawmill for producing dimensional lumber. It consists of two blades attached at a right angle to one another, allowing the production of a dimensional member in one pass of the mill. Distributed sawmilling has the potential for distributing the production of dimensional lumber, thus creating less dependence on clear-cutting of lumber plantations. Wood construction is one of the earliest methods of building shelter. Current lumber production is highly concentrated industry save the specialty wood shops producing for novelty wood workers. Unsound harvesting practices and high transportation costs make commercial lumber environmentally costly. Timber can be locally harvested. With a simply designed, low cost sawmill we can produce fine quality lumber sustainably and economicaly.

| ===Design===
| |
| Current phases in bold. Next phase in italic.
| |
| | |
| * With design rationale, put it up for review on Red Pages
| |
| | |
| '''''* Design in 3d, go through cutting workflow, split up design into pieces and finish them one at a time
| |
| | |
| ''* Get feedback on sub-piece design, post on sawmilling forums
| |
| | |
| * Iterate design and feedback until design is finalised
| |
| | |
| * Make bill of materials for final design
| |
| | |
| ===Test Construction===
| |
| | |
| * Build space frame and platform frame as a first test, to test x axis motion
| |
| | |
| * Test x axis motion
| |
| | |
| ===Construction===
| |
| | |
| * Purchase one blade, 30", 2 blades, 12"
| |
| | |
| * Build cutting head - gear up the blade
| |
| | |
| * Install all safety devices before operating
| |
| | |
| * Test sawmill operation without blades attached

| We have a [[hydraulically-driven]] PTO motor as a start. It will be powered by [[LifeTrac]]. LifeTrac has this pump from Northerntool - [http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200329724_200329724]:

| 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.
