Title: Mixed loads
Post by: Bnewman712 on July 21, 2018, 11:04:46 PM
Can you dry mixedloads? And also mixed sizes? If I have only 150 bdf of 4/4 cherry and only 200 bdf of 8/4 cherry can I dry them together? What can happen? Thank you

Thicknesses of the same species can be mixed for most species.  You would dry based on the thickest lumber.  The exception is with the white wood species, where the required slower drying of the thicker lumber may result in some white-color loss in the thinner.

For air dried stock, most any hardwood species can be mixed as the kiln schedule for most species at 20% and lower MC is the same.  At higher MCs, check the notes in Tables 7.11to 7.21 in Drying Hardwood Lumber.
