Kiln dried Douglas fir = bad

<< < (6/6)

TSA:
DC, i dont know how it effects spine-others may have input. it may or may not have a significant effect. i just know that the structural integrity is effected.
as for weight , that will simply be defined by the wood mass plus the water- same as any piece , irrespective of how it was dried, i guess.

Willie, i will take  a look at that link, many thanks.
i am just adverse to any heat usage- i hear you about the lower heat. the higher the heat the greater the damage, so lower heat would mitigate some of the damage for sure.
all wood drying kilns have a dehumidifying aspect to them. As the moisture is expelled from the wood, it needs to be replaced with lower MC air.

if the "drier" had No heat and just a dehumidification process, that would be the best, as now you are relying on the process of osmosis.
(no ill intent, but just a quick explanation of osmosis, its the process of moisture migration from a high pressure area to a lower pressure area in an attempt to stabilize the pressure- as i remember the explanation from high school hundreds of years ago!!)
this system would work the best, but would not be commercially viable- the process would just take way to long.
i would hesitate to even call that a kiln, as the word kiln implies the use of heat. i would simply call that an air  drier

Bryce:
It's transference of water or other solvent through a semi-permeable membrane, in this case; the cell wall;)

loefflerchuck:
Update: I took the 1/2-" squares of fir and rounded the corners on my table sander. Most made it through the Veritas after that.

TSA:
good job, success!! :) :)
i need to make a correction here, after a bit of head scratching, and after what Bryce said,  the term "osmosis" is the incorrect term- my apologies.
osmosis relates to a transference between two different concentrations of solute.
more correctly, what we are talking about is simply moisture moving from a high-pressure area to a low-pressure area, much like the weather, or like wood finding EMC ( equilibrium moisture content).
thanks, this has been a great thread- glad after all this - Loefflerchuck has had success with the shafts!! :OK
