Since photographs are not allowed on the Cob list this letter has two  
versions one with pictures and one with out.  If anyone want the  
version with pictures please, send me a request off the list.
Thank you,

Heather, First I should clarify that the word "columns" does not  
refer to columns in the conventional sense I am building a stand  
alone fire wood shelter which will be resistant to wind and rain and  
yet open on both sides to allow the wood to dry. as such the "columns  
are actually L-shaped and T-shaped wall segments which will support  
salvaged 2" x 8" x 12' roof beams. The footings are salvaged  
cinderblocks so the wall segments are 8" thick and 40" front to back.
Note Figs. 1, 2, and 3

Fig. 1 Wood Storage area


Fig. 2 T-shaped column


Fig. 3 L-shaped column



If you are interested in conventional thin columns the first  
structure that I worked on with Ianto Evans included a wall with  
window mullions that were 4" x 12" x 4' and when I went to visit cob  
cottage in Coquile, OR I noticed additional mullions that were 4" x  
12" x 6'-7', However when it comes to very tall very thin columns it  
is much better to just find an attractive piece of split wood and use  
that.
Note Figs 4, 5, 6.

Rob: Regarding the wood fibers they were produced by a conventional  
6" wood chipper with a gear driven feeder. My friend Robert bought  
this chipper about 6 months ago and at that time the blades were  
brand new and he produced neat well defined wood chips, but as the  
chipper got older and the blades became worn and out of alignment the  
chipper stopped producing neat chips and started producing shreds of  
wood instead.
Note Figs 7, 8, 9
