Why I asked about the type of oak is that I was told red oak has an open cell structure and can allow water to wick into the wood easily which isn't the case with other types of oak, maybe in this case that is preventing any cellular swelling or allowing any pressure to squeeze the water out. Can you repeat the test with white oak. I have some English oak here but my force gauge is out of action until I replace the loadcell lead.

--------------------------------- My white oak is still in logs so sample prep could take a while and this is a busy time of year, I need to split and stack next year's firewood to dry, upgrade a few things on the sawmill and get the logs out of my front yard. I paused outdoor projects in mid December and began again in February. The question is academic if steel wedges and feathers are available.
The gauge has warmed up and the pressure recovered, so maybe the gauge oil shrank?

Did you read that page as they mention the process I mentioned and you were trying to test.

I usually observe this with relatively new pavement laid down over an area that had weeds growing but graded off. The "weed" will push the pavement up, volcano like and continue growing. Some examples of questionable authenticity:

Some data with footnotes down the page for plants, roots and fungi...
=== "The action of turgor pressure on extensible cell walls is usually said to be the driving force of growth within the cell.[17] An increase of turgor pressure causes expansion of cells and extension of apical cells, pollen tubes, and other plant structures such as root tips. Cell expansion and an increase in turgor pressure is due to inward diffusion of water into the cell, and turgor pressure increases due to the increasing volume of vacuolar sap. A growing root cell's turgor pressure can be up to 0.6 MPa, which is over three times that of a car tire. Epidermal cells in a leaf can have pressures ranging from 1.5 to
2.0 MPa.[18] These high pressures can explain why plants can grow through asphalt and other hard surfaces." ===I hastily done paving job or hole patch with asphalt during the summer quite often demonstrates this...

Good catch. Botany isn't among my strengths, at least I knew the word.
They are authentic all right!!! I've seen even worse after some fly-by-night driveway pavers have "enlarged" a driveway.
Hello again all. Another update:
"Batching" - all equipment works fine and good "production-rate". Seems "proven". Very unexpected bonus. Plans now on what end-point sought for mine with clearing boulders.
All seeming brilliant. Rich S
