Based on the grain pattern, color, and end-grain structure shown in your photos and video, this wood is Red Oak.

Here is a breakdown of why:

Key Identifying Features

• The Grain (Face): Notice the very prominent, open, and "porous" grain lines. Red Oak is famous for this "cathedral" grain pattern, which you can see clearly in the video and images 1000000900.jpg and 1000000908.jpg.

• The End Grain: In image 1000000909.jpg, the end grain shows distinct growth rings with large, open pores in the earlywood (the lighter, wider parts of the ring).

• Color: It has a distinct reddish-pink or warm tan hue. While it looks somewhat brown in certain lighting, the pinkish undertones are a giveaway for Red Oak versus White Oak (which tends to be more olive/tan).

• Texture: You can see how the wood "splinters" or tears out along the grain in the video. Oak is a very hard, brittle wood that behaves exactly like this when it meets a dull blade or is handled roughly.

Dimensions (per your photos)

• Thickness: Approximately $3/4$ inch (1000000901.jpg).

• Width: Approximately $4$ inches (1000000903.jpg).

• Length: Approximately $72$ inches ($6$ feet) (1000000902.jpg).

A Quick Tip for Woodworking

Red Oak is a "ring-porous" wood, meaning those grains are actually open straws. If you were to blow into the end of a short piece, you could actually bubble soapy water on the other side! Because of this, it is not great for outdoor use (it rots easily if moisture gets in those pores) or for holding liquids. It’s perfect for furniture, trim, and flooring, though!
