Hi Guy's
I am currently reading a book entitled "The Art Of The Lathe" by Patrick Spielman, an excellent read by the way, but moving on to the point, under the chapter on "wood seasoning" the auther describes various drying method's ie peg etc in use, the last referal being the esp 90 method.
The name "ESP 90" is a acronym for Eugene Sexton Process that was developed in 1990 , apparently after years of testing, a four step cheap and simple process was created , that when used left the wood with no normal drying stress distortions.
In 1991 a company was set up ES TECH INC, to protect and market the process , the company claimed in there published data that :
A. THE PROCESS ELIMINATED THE BLUE STAIN'S IN WOOD
B. ELIMINATED CHECKING AND SPLITTING AS IN CONVENTIONAL
METHOD'S
C DRIES WOOD TO 8% MOISTURE CONTENT
The cost involved, approx $1.00 per tree, and the time involved equates to 100 trees per man day.
I have checked on the internet for any up-date on the matter but to no avail, I was wondering if any of our learned friend's on the forum can shed any light on the subject.
Thank's Rod
PS I still havent purchased a lathe yet I've checked a few out and I am leaning toward's a Jet 1642 with the variable speed, sell's for approx $2450.00 I would appreciate any comment from anyone with regard's to this make and model.
Thank's again ROD.
