How long can logs sit before milling?3/6
I am getting swamped with logs that I canít keep up with. Iím trying to prioritize logs and I generally mill walnut first (although I do like milling walnut that has been sitting and the bark is off. Seems more stable and less sapwood.) I have so much ash that I have set some of that to the side even though the ends check a lot. My question is, what species am I going to regret letting the logs sit for a year or two before milling? Mainly wondering about my white oak and burr oak and sugar maple. Are they going to degrade if they sit in log form.
I would not let maple of any kind sit long. In my admittedly limited experience it degrades very quickly. Ash degrades very quickly, too. White and red oak can sit a very long time. I've milled some that have been sitting for more than a year. The sapwood on the red oak was all punky but the heartwood was perfect. Walnut can sit a very long time, as you said.
If you have no choice then I would cut the ends back on the logs you want to save for later and seal them with Anchorseal. That will prevent most checking and decay.
Thanks. I have them all anchor sealed. I was a little worried about the oaks getting case hardened and getting that grain separation. But, that sounds good from your experience.
Casehardening isn't caused from logs sitting on the yard.....it's from incorrect kilning techniques as speeding up drying process but can also associated with the heat/sterilizing process. Dr Gene can give you the correct details as it is more technical than I can explain.
Logs sitting on the yard affects checking, staining and color loss issues. Which affects production type milling's bottom line at sales UNLESS you're in the specialty market with all the defects and spalting.
