Anyone have a go-to training to keep NHLA rules fresh and applied on the shop floor? I’m an inspector, and last week I rejected 14 FAS hard maple boards for wane and skip that wouldn’t pass current interpretations, and I want a structured refresher that also covers moisture verification — calibrating a Wagner to confirm 6–8% MC for interior. Prefer courses or webinars that issue CE hours and focus on practical grading and compliance, not just theory.
NHLA webinars cover wane/skip; verify ‘6–8% MC’ by oven-dry spot checks to calibrate your Wagner: https://nhla.com/education/.
I’ve gotten the most from NHLA’s ITS refresher plus a monthly “meter sanity check”: zero the Wagner on its calibration block (like zeroing a caliper), then compare shop readings to expected EMC from RH/temp — 35–45% RH at about 70°F lands about 7–8% MC — using an EMC chart like https://www.woodbin.com/calcs/emc/.
Checking your shop’s lumber stock against the NHLA standards regularly really helps keep those interpretations fresh. I’ve found that joining a local woodworking group can provide insight and hands-on tips too, like calibrating your Wagner directly with fellow inspectors. Have you tried reaching out to any local associations?
