Sourcing 120 board feet of reclaimed oak at 6 a.m., the meter shrieked 18% like it caught me cheating on kiln-dried. Anyone else get heckled by their own tools while trying to keep it FSC, low-VOC, and strong enough not to fold like a cardboard chair?
That ‘18% at 6 a.m.’ is mostly cold-stock drama — sticker the reclaimed oak inside with a cheap box fan for 24–48 hours, warm the meter, and recheck with the oak species/temp correction. If it’s still north of 12%, rough mill 1/16–1/8 heavy and let it nap a day so it doesn’t fold like that cardboard chair. You running a dehumidifier in that FSC/low‑VOC shop, or trying to keep it all passive?
Before the meter roasts you again, take a quick jointer pass to make a flat, clean spot and rescan — pinless meters over rough reclaimed faces read “extra soggy” like they’re judging your life choices. If it still screams, run a magnet for hidden nails/iron and sanity-check your shop’s EMC with this chart: https://www.wood-database.com/wood-articles/equilibrium-moisture-content-emc/. Pin or pinless on your end — if pins, try end-grain or insulated probes for a truer core read.
Pinless meters can spike over nail lines or hidden hardware; pair @chajohn’s flat-spot pass with a quick rare-earth magnet sweep so you can rescan a clean patch or flip the board. Do the high spots line up with old nail holes, or is it screaming ‘18%’ everywhere?
At 6 a.m., that “18%” might just be cold-board blues; dawn air makes oak read high until it warms up. Stick insulated pins 1/2" deep after 20–30 minutes in the shop and set the species correction for oak, @OP. If it still shrieks, the EMC math agrees you’re not there yet: https://www.wood-database.com/wood-articles/moisture-content-and-wood-movement/.
