The Liberator is OSE's automatic, high throughput Compressed Earth Brick Press. It is named The Liberator because it is intended to free people from the single highest cost of living - housing. See [[Cost of Living]]. | |||
The CEB is at product release status and is being actively manufactured at Factor e Farm. The presses was used heavily as a part of the [[Factor e Farm Infrastructure Buildout 2011]]. Builds using the OSE CEB ress continued with the [[Microhouse 1]], [[Microhouse 2]], [[Microhouse 3]], and [[MicroHouse 4]] built in 2014 - [http://www.prweb.com/releases/2015/01/prweb12440135.htm]. We have also built a utility room brick floor and an 8' wall section out of CEBs in the 2016 build of the [[Seed Eco-Home]]. | |||
In 2020, we did a [[CEB Microhouse Build in Belize]]. | |||
The bill of materials cost of the current, fully-automated machine is about $5000 US. See [[CEB Press#BOM]]. | |||
The machine can also be made as a manually-controlled version with hydraulic valves. Other options are: | |||
*small or large hopper | |||
*with or without hopper shaker | |||
*automatic controller at 6-10 bricks per minute, depending on power unit | |||
'''We are currently selling the full machine without power unit for $10k FOB Kansas City, lead time 2 months. Email info at opensourceecology dot org.''' | |||
*Price is FOB Kansas City, Missouri, USA, for a fully assembled machine, with quick couplers, ready to be plugged in to a power source. Price for other packing/crating options is extra. | |||
*Delivery time: machines are produced during scheduled production runs, with 8 weeks lead time from submission of payment. | |||
*Buyer is encouaraged to attend the build event - to learn how the machine is designed, built, and therefore, to learn about repair and modification. Basic instruction on using FreeCAD will be provided for viewing the CAD file. An operating and maintenance manual will be provided to the client. The buyer is encouraged to brind additional people to the build event to learn about the machine. | |||
A tractor loader is used to provide approximately 2 cubic yards of soil per hour at at 6 block per minute pressing rate. A tractor loader is needed to keep up with the machine throughput. Approximately 3 people are required to keep up with the machine for stacking the block upon pallets. Approximately 30 people would be required to load the machine manually with shovels and buckets if no tractor loader were available. At the minimum, 4 people (1 tractor operator, 3 stackers) are required to produce palletized block on an all-day basis. | |||
==Specifications of the Standard Model== | |||
*Block is plain block, not interlocking. Please see discussion on [[Interlocking_bricks]] | |||
*Version 17.08 is our most current model. See [[CEB Press Genealogy]] for past versions. | |||
*Open source hardware, controller, and software ([[CC-BY-SA 4.0]], [[GPLv3]]) | |||
*Controller is fully automated for hands-off operation | |||
*Does NOT come with a power source - it is powered by a hydraulic power source, such as by our [[Power Cube]] or a tractor hydraulic take-off. | |||
*Full size bricks are 4"x6"x12", plain flat-faced bricks | |||
*Brick height is adjustable from 2"-4" | |||
*Brick dimensional variations: +/- 1/16". This assumes uniform soil. Soil uniformity will determine height uniformity of brick. | |||
*The standard model guarantees 6 full-sized bricks per minute at 12.5 gallon per minute hydraulic flow. See [[Brick Pressing Calculations]]. Brick pressing rate will increase with a higher hydraulic flow, up to the maximum rated flow of the hydraulic solenoid. Hydraulic solenoid valve is rated for a maximum of 10 gpm fluid flow at 3000PSI. | |||
*Cost of production for actual block ranges from 5 cents to 40 cents per block - depending on amount of cement used for stabilization (0-10%) and cost of labor (free to $25/hr). See [[Cost_of_CEB_Block]] | |||
*Fuel consumption with [[Power Cube]] running at 12.5 gpm fluid flow - about 1 gallon per hour | |||
*System hydraulic pressure - 2400 psi | |||
*Comes with hydraulic quick couplers ready to be connected to a power source | |||
*Weight - 1700 lb | |||
*Moving: brick press is moved with forks. Footprint (with legs in the inner position) allows machine to be placed in the bed of a 3/4 ton pickup. It has adjustable legs for uneven terrain. Machine can be moved around on a trailer (not included) | |||
*Material cost: $3000-$6500 depending on suppliers; manual machine (without hydraulic solenoid, machine costs $1000 less in materials. Production cost for a full kit: US$5000 above the bill of materials/supplies/consumables cost, paid by the buyer. Production currently occurs in [[Extreme Manufacturing]] Workshops - where the buyer is invited to the build so they understand how the machine is built - and is part of the buyer's Lifetime DIY Warranty.

Overview
CEB Press (aka "The Liberator"). See CEB_Press_6#Instructional_Files for detailed pictures of the latest machine build (v6), and for an exact picture of v6. Version shown is v3.
Bricks pressed on The Liberator
The Liberator is OSE's automatic, high throughput Compressed Earth Brick Press. It is named The Liberator because it is intended to free people from the single highest cost of living - housing. See Cost of Living.
The CEB is at product release status and is being actively manufactured at Factor e Farm. The presses was used heavily as a part of the Factor e Farm Infrastructure Buildout 2011. Builds using the OSE CEB ress continued with the Microhouse 1, Microhouse 2, Microhouse 3, and MicroHouse 4 built in 2014 - [1]. We have also built a utility room brick floor and an 8' wall section out of CEBs in the 2016 build of the Seed Eco-Home.
In 2020, we did a CEB Microhouse Build in Belize.
The bill of materials cost of the current, fully-automated machine is about $5000 US. See CEB Press#BOM.
The machine can also be made as a manually-controlled version with hydraulic valves. Other options are:
- small or large hopper
- with or without hopper shaker
- automatic controller at 6-10 bricks per minute, depending on power unit
We are currently selling the full machine without power unit for $10k FOB Kansas City, lead time 2 months. Email info at opensourceecology dot org.
- Price is FOB Kansas City, Missouri, USA, for a fully assembled machine, with quick couplers, ready to be plugged in to a power source. Price for other packing/crating options is extra.
- Delivery time: machines are produced during scheduled production runs, with 8 weeks lead time from submission of payment.
- Buyer is encouaraged to attend the build event - to learn how the machine is designed, built, and therefore, to learn about repair and modification. Basic instruction on using FreeCAD will be provided for viewing the CAD file. An operating and maintenance manual will be provided to the client.
