Home manufacturing, recent post #5

http://www.planetaryrenewal.org/ipr/ultralc.html  (a little more 
esthetically appealing than a modular-panel foamed concrete quonset, or 
simple gable-roof (at least make it wide-overhang), but though this 
design envisions use of a polyester-resin mix, it could use 
foam/fiber/acrylic/pozzolan mix just as well---with a lot better 
insulation factor.)

http://www.northcoast.com/~tms/stone.html  (Northcoast has always been a 
fine source for building low cost homes (and other buildings), still is, 
and has some new books worth reading (at you local library first).
Buy the Ken Kerns of course, and you've GOT TO Own the Christopher 
Alexander books on "Pattern Language"---no more boring, 
marriage-destroying ninety-degree, unlit, no-vista Indiana Boxes.  
"Making Concrete Ornaments' is a failsafe source of home manufacturing 
income, and not discussed here, give real consideration to the cheap and 
excellent India compressed earth blockmaker---nothing cheaper and few 
things better that the dirt under your feet.)

http://www.earth-auroville.com/index.php?nav=menu&pg=auram&id1=7  (the 
Auroville CEB press to which I referred to above. Makes lovely buildings 
at cost little more than plain adobe, and much stronger, 
insect-resistant, impervious to rain if a little asphalt is mixed in.)
This is the manual press version---used to cost about $800 laid into a 
U.S. Port of entry. There are engine-hydraulic press versions for lazy 
Americans---or those who want to make a business of seling compressed 
earth block to building contractors at a fraction of the price of 
concrete block)  The engine-hydraulic presses as I remember, use a 
rotary table to put earth mix in the molds, press it in next stage, and 
eject the molded part in a third.  A note as added economy, besides the 
interlocking block, you only use one centimeter of earth-mortar between 
blocks---same mix as the boocks are made but slightly wetter.)  
(some new stuff on U.S. blockmaking machines---developed in past two or 
three years.---from Pliny Fisk)

http://www.motherearthnews.com/index.php?page=arc&id=5256  (Ken Kern 
excerpt from Mother Earth News---forget about the Cinva Ram 
though---good in its time, it is now far-outdated)

http://www.gtz.de/basin/publications/earth.htm (lot of books on 
CEB---French CRAterre started commercialization of compressed earth 
block constructionl)  
(most CEB is good enough for a government jot---GOOD CEB is a little 
more complicated.)

(testing blocks by standard means to get meaningful result---if you sell 
earth blocks to a building contractor, he is goint to want to see 
building specs on them)  
(miscellaneous symposium notes)

Oh, yeah---you want to build any structure, build a model first, better 
to build a dozen and select the best.

design innovations)

http://www.northcoast.com/~tms/wood.html  (Old Northcoast photo of 
cordwood masonry that any little old lady in tennis shoes can 
build---especially if the house uses few posts, is round or hex, and has 
a bond-beam to tie the cordwood and provide a component to which roof 
members are attached (imbed L-bolts or steel plate tiedowns.) Someone on 
the Homestead List built a cordwood masonry house, forgot who.
