I'm off on a tangent, but I'm interested to know how to dry the gnarly grained stuff like Chris Schwarz discussed this morning for naturally shaped stick chair arms. How to best dry it to an unchecked & stable state?
If I interpret this correctly, I have learned a new concept. The moisture % measurement can go to 100%? meaning 50% of the total weight of the wet log? This then means that a 20% moisture measured log has a total water weight of 10% of the weight of the log? Is this right?
No unfortunately not… moisture content (MC) can actually be over 100% actually.
MC is calculated by taking the weight of the water in the sample divided by the dry (bone dry zero water) weight of the wood cellulose multiplied by 100 for the MC%
let’s say a 100gram wet sample after being taken to bone dry weighs now 91grams that was 8grams of water divided by 91 ×100 would be 8.79% moisture.
This series is interesting. I’ve been removing several of these trees on the farm. The trick is to kill the roots before you cut them. Once dead they are very brittle. Maybe I’ll try to salvage the larger logs for lumber if your tests go well.
I talk to my students often about "nerding out" and getting into the technical side of what they're doing instead of just blindly building. Thanks for sharing!
I learn so much more about wood from you! I admittedly don’t know a lot about the drying process so these blogs are great. 👍
Thanks man. Maybe I should do a wood drying series.
I would enjoy that.
I’d love this.
Add me to the list.

Yes, someone who’s only tried a few batches of lumber. I would enjoy reading that.

I should probably do a blog on this.
The more you learn, the less you think you understand.

This was such a great read! Really loving this whole series.
