Pin meter and pinless reading 3 to 4 points apart on the same kiln-dried oak. How do you actually decide what to trust before milling case sides?
Garage hobbyist here, mostly building case goods for the house. I've got a small batch of 4/4 white oak from a local mill that's been sitting stickered in my shop for about 7 weeks. Shop runs about 40 to 50 percent RH this time of year. My pin meter reads 9 percent on the rough faces. My pinless (calibrated for hardwoods, set on the dense scale) reads more like 12 to 13 percent on the same boards. Surface temp is whatever the shop is, maybe 62 degrees.
I know pin meters read shallower and pinless reads deeper into the board, and I know rough sawn faces throw both off some, but a 3 to 4 point spread feels too wide to just shrug at before I joint and start cutting case sides. Couple of questions for the mill rats and finish carpenters in here:
How much do you trust either reading on rough lumber, vs waiting until you've got at least one face jointed flat?
If your two meters disagree, do you split the difference, trust the deeper one, or just give it another two weeks and re-check?
And does anyone actually let kiln-dried small-mill stock acclimate to a measured EMC for the shop before milling, or is "give it a month and check again" basically the whole protocol?
Trying to avoid the cupped panels I gave my brother in law two Christmases ago.
