What sort of oak? I'm reminded my doctor had an oak mail box made at
some expense and it didn't fare well outdoors and from what I was told
by a couple of woodworkers it must have been red oak as that's not
durable outdoors. English oak, European oak and American white oak is
durable so maybe some wood is better for splitting rock than others.
I had another look at the wet wood splitting and saw mention of wet wood
being hammered in and allowed to freeze in the winter to cause splitting.

The load cell is an older model of this, last calibrated in 1992.

The rest of the fixture is a C clamp pressing the wood against the plunger.
Two thin pine wedges tapped together gave a splitting force around 100 Lbs. I doubled it to 200 Lbs, one tick mark,  on a 3/8" thick square of red oak in a plastic bag and added water about 20 minutes ago. So far the gauge needle hasn't moved.
