How to Properly Mill and Season Raw Oak Logs?
Asked by CraftyNinja42
I recently got my hands on some oak logs from a tree that was removed in my neighborhood. I've got a bandsaw with an 8" resaw capacity and I want to try milling my own lumber for some special projects. My main question is whether I should let the wood dry naturally first before milling it into planks, or should I saw it into boards right away with the intention of milling again later? I don't have access to a kiln like the big lumber companies, so I'm a bit concerned about the right approach. I'm hoping to make something meaningful from this tree, which holds sentimental value for my family.

Definitely seal the end grain of the logs first before you do anything else. After that, it's a good idea to saw the logs into boards so they can dry. From what I know, air drying typically takes about a year for each inch of thickness—for example, an 8/4 board will take about a year, while a 4/4 board might be good to go in just six months. I like to be cautious and would recommend cutting a bit thicker than you want (maybe around 1/4 inch more) so you can double mill it later. Let the wood move a bit after the initial cut, then flatten it again later!

Seal the ends of the logs immediately! Seriously, do it right now. After sealing, you'll need to work out the rest of the process, but getting those ends protected is the first step to prevent cracking.

TimberTamer99: I had never thought about double milling lumber. Thanks for the idea!
DryingMaster68: Don't forget to stack them properly with some weight on top after you saw. Make sure there's enough air circulation around the planks as they dry!
