8/4 Ash 4" wide 36" long (S4S)


Ash wood possesses decent strength properties for its weight and is shock resistant. It has high elasticity which makes it a popular choice for bows and steam bending projects. Applying a stain to Ash produces a similar look to Red Oak. Ash trees are currently under attack from invasive emerald ash borer in the US. This has steadily increased the price and reduced the availability of wider stock.

What is 4/4?

When lumber is cut at a lumber mill, the thickness is traditionally measured in quarters of an inch. For example, 4/4 equates to 1 inch and 8/4 equates to 2 inches thick.

When you order ash lumber from us, it is surfaced on both sides (S2S), resulting in a loss of about 3/16 of an inch in thickness.

4/4 lumber will come surfaced to 13/16" thick, and 8/4 to 1 & 13/16".

After sanding or shaping, you should be left with about 3/4" workable material.

Looking for thinner material? See Project Ready wood.

What does S4S mean?

S4S means the lumber will be surfaced on four sides—it is planed smooth on the top and bottom face with both edges trimmed straight and to size.

All S4S and S2S lumber is planed but not sanded. It will need sanding before a finish can be applied.

Looking for sanded, ready-to-go wood? See Project Ready wood.

Is the wood clear?

All our Lumber is Select and Better (Sel&Btr) grade unless otherwise specified. Select and Better is the highest grade available.
Most pieces will be 83% to completely clear. Small peices are usually completely clear, while larger pieces might have small defects or a few sound knots.
