Any ecosystem that has trees offers the opportunity for local production. Thinning of woodland promotes diversity and creates space for new trees to grow while preserving the ecosystems natural cycle. The design for dis-assembly proposed enables the sawmill to be transported over the road and to the trees. The potential for efficient midsized wood milling is no joke. With mill capabilities to produce 2400 linear foot of wood in a day, pretty reasonable, you may not see the lumber yard again. With sawmill like this you will be friends with every farmer, woodworker, and forester in the area. Sawing your own lumber affords you the ability to create beautiful and quality planks for peanuts while offering piles of satisfaction.

The ecological impacts of commercial logging are devastating. Much of that lumber consumed is harvested by means that are unsustainable clear cutting forests and devastate ecosystems. Timber is BIG business, the inertia the logging companies have continues the cycle of centralized production and unpractical philosophies of every growing industry. The sawmill we aim to develop has the capabilities to restore lumber as a local resource using local woodlot that is harvested in a responsible and sound way. Thinning of forest, fallen trees, cleared lots all afford the opportunity for usable lumber while the scraps and sawdust are used for fuel and/or mulch. This method lends itself to a closed circle product cycle that returns production to the masses.

A Lumber mill enables custom lumber production on site using locally available timber. An easily replicable lumber mill creates real value for the producer at a low cost of entry, a necessity for self sustaining community decentralized economy. The simplest implementation of a mid-sized sawmill is using a table with guide track running parallel to log that a chainsaw mounts. Using Lifetrac as a power source we will build a high performance ripping chainsaw, 25hp hydrolic motor coupled to a belt pulley to increase rpm to drive our chain sprocket with 3-4 foot bar.

Wood construction is one of the earliest methods of building shelter. We as we continue our CEB building lumber has been purchased to construct the trusses and will be needed to ruff-in door and window jambs. 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 and with a simply designed,low cost sawmill we can produce fine quality lumber sustainably and economical.
The simplest apuratus in terms of design maintainence and use consists of a chainsaw mounted on a track. The most comparable table with track costs $2700 USD without the saw, $3700 with saw (http://www.logosol.com/_sawmills/m7/)for a wimpy 6.3 hp gasoline motor.
We are proposing a 25hp table/track/chainsaw mill capable of sawing lumber 30' wide and up to 12" long using 25hp hydrolic motor powered by lifetrac and designed, funded, and all developments posted via the open source collaborative that is OSE.

Babington Burner

Bob: /* Internet Research */

=Introduction=

This burner is important because it is a versatile source of heat for: space heating, metal melting, glassworks, pottery, steam engines for remote power, heat engines for mobile power in cars and tractors, and many others. We can use it with any waste oil - crankcase, vegetable, etc. - plus [[Pyrolysis Oil from Biomass]] once we develop it. It is not a far stretch to produce pyrolysis oil- see this simple experimental proposition. Do you think this would yield useful amounts of liquid fuel?

=Background Reseach - Design Rationale=

So what is the synthesis of available information regarding the Babington Burner? [http://groups.yahoo.com/group/wastewatts/?yguid=233802573 Wastewatts] is one Yahoo group that deals with the Babington. What is the state of the art for:

*The type of ball used - size, shape (endcap with groove, ball, doorknob). Does wall thickness matter
**Do people have trouble with debris from inside the ball clogging up the ball hole? We had trouble, so we are cleaning our brass doorknow with an overnight vinegar bath.
**What is the number of holes that people have used? I've seen 1 and 2 hole versions on the internet.
**What is the hole size range? I've seen .01-.02 being used.
**What is the pressure range used?
**What is the range of flame size possible for a clean burn?
*Did anyone measure fuel usage rate and heat output in BTU or kW?
*What is the optimal pump used for active fuel pumping?
*Is there an upper limit to the desirable air pressure for the burner ball?
*What is the best type of shroud to use?
**Pipe section - what length, diameter, wall thickness?
**Air holes - what is the number and location for these?
**Ends of pipe - the flame end is open, and burner ball end is closed?
*Does anyone use forced air for additional air input?
*Applications - has anyone field-tested:
**Shop heating?
**Water heating with heat exchanger?
**Steam generation?
**Steam engine operation?
**Combined heat power applications?
**Metal melting furnace?
**Pottery kiln?
**Brickworks?
**Glassworks applications?
**Backup power generation with steam engine?
**Mobile power application in steam cars and tractors?
**Flame week killer?
**Flamethrower for parades?
*What measures need to be taken to assure the flame does not go out?
*What is the optimal temperature range for the fuel feed, and how to preheat the fuel?
*What are other issues/quirks that make the Babington unstable?
*What is the expected lifetime of a burner ball? Is this an issue?
*Is regular cleaning required, or can this system be self-cleaning in continuous burning?
*Does anyone have effective, complete system designs that we can replicate?

= Burner Ball=

Here is a brass endcap with a channel for directing oil flow:

[[Image:babsendcapball.jpg]]

Does this work better than a ball?

=Implementation at Factor e Farm=

On 9.29.08 we started to put together our Babington burner.

We drilled a 0.0135 inch hole in the face of a hollow, brass doorknob - and brazed on a fitting that supplied compressed air at a constant pressure between 20-35 psi. We were able to atomize water but when we tried motor oil we had problems. We were able to produce a bit of a flame but never sustained burning. Two possibilities: 1) the hole became clogged from debris inside the burner ball, 2) the oil was not heated sufficiently. Has anyone had success in sustaining a flame over a long period? What is a good method for automatic ignition? Best way to regulate the flow over the ball? Any feedback is welcome from experienced Babsmen.

Technique: we attached a rotary tool to a regular drill press - to utilize the up-down motion of the drill press with the rototool as the work tool for the .0135 micro drill bit.

Water atomization was successful, seen in the last picture. Fuel atomization was not.

Next steps: heat oil properly - for now on a stove top, and use a metal dispenser container. Clean out the inside of the burner ball.

Results to be posted evening of 9.30.08:
