Topic tags/keywords: walnut

Hi everyone- I have this walnut slab, which is 3’ wide and 8’ long. It’s been in my shop for over a year, and was in my garage for 2 years prior. It has a slight crown to it, and I’m taking it to a friends shop who has a Timesaver machine, to flatten it out. This price also has checks in each end, and ultimately I will be sawing about 12” off of each end so it will fit in its intended spot.

My question is should i be worried about this piece moving more (crowning again), after I saw the ends off? Should I saw the ends off after I flatten it out?

Thank you!
-Brian

What is the current moisture level [MC] in the wood? If over about 8%/10%MC, then there is a possibility it will move more/again.
Three year air cure is not excessive for a piece that is 2” or thicker.
Do nothing to remove the ‘split ends’ until it is in the neighborhood of 8% MC or lower.
I assume you have had the ends sealed since the tree was felled.

I think that it should be stable, especially since the crown is only slight, and that formed from green to its current state. If you could measure the moisture content, that would be preferable. If the moisture content was 12% or less, I don’t believe that it will move a lot more.
