Some thoughts - probably redundant but in one place.
Seems, as I thought, that 99.8% of drying research is for commercial operations. A couple of the sites I want to revisit to contact the professor for details on small operations.
Existent processes appear complex and require frequent monitoring using equipment unavailable to the normal woodturner. It is notable that these specific procedural details have appreciable affect on the quality of the end product including even chatoyance. The development of software to control this is relatively new. There appeared some left to do on the sensing devices. There would be some individuals who could downsize all this I would think. Maybe not cost-effective enough to ever resell but sufficient for their personal resources including time and money. Keep in mind Bill Rubenstein's negative experience with a Woodmizer kiln. More on that could be relative. Possibly the rate of drying was the culprit since that is what all the software is essentially about. Further, it could have been designed for softwoods or require pre-drying to perform at its best. Tennessee is notable for trying to specifically handle red oak problems.
The qualified exceptions are solar and air drying. Solar being a little more detailed than air. This is not woodpile air drying though there was a site that addressed that specifically that I want to revisit.
The amount of info available was beyond the time available. Some isn't worth additional time, others have real potential for ideas. Note the application of weight or hydraulic pressure on drying stacks to prevent damage to the upper layers. The principle being to lock the material into the shape you want while drying. The diagrams noting location of the sample within the cross-section of the log and its affect on movement types are interesting.
As Charlie, Arch, and many others have noted there are definite differences in specific woods, even what region the wood comes from, etc. Leading to the conclusion that even with an overall idea/plan/setup there will have to be individual experience applied eventually. There were specific gravity tables by type, etc. George has done much in that regard with FPL but there's other sources to compare any differences in conclusions. I usually prefer private enterprise to government for conclusions unless there's an axe to grind.
There appears to be some substantiation of some of the ideas posted on RCW. Vacuum, heat, dehumidifiers, displacers, solar, and maybe something I've missed thinking of. There are among us some who could assimilate this data and do a better than job than me with conclusions so I have no ego stamp on any of this. I just started trying to bring a lot of the available info to one spot for review. It has been enlightening and even encouraging.
Bottom line: We're where we were with the exception that there's a list of links available in one spot for anyone who'd like to form their own opinion or get ideas. Then if there were a similar list of woodturner's ideas you'd have the best of the rest to chew on.
Just remember that more deer are killed with a 30-30 lever action rifle than any other (ballistically inferior to almost anything but the most USED deer gun). At least, that was the case back in my reloading days.
