This is a telling photo. First notice in the background
you can see long boards spaced out to dry. Air drying takes a
lot longer than kiln drying, but air drying allows the board to
keep 100% of it's strength. The kiln often weakens the wood.
Max Baldwin is shown here feeding two foot boards
into the SANDMAX wide belt sander. This process opens the grain
so when the sealer is applied it can soak in deep. The standard
technique is to use a moulder (like a planer) to surface the boards,
but when sealer is applied it soaks in blotchy.
