Across
- 3. man-made sheet material, made from small chips of timber glued together to produce a dense sheet.
- 5. an attractive light colour, with an open grain, and is strong and tough.
- 6. pale coloured with an aesthetically pleasing grain. It is lightweight, easy to form and is often used for construction and decking.

- 15. attached to a crankshaft, which rotates

Down
- 1. has a repeated up and down motion or back-and-forth
- 2. durable, oily wood with a tight grain. It is moisture resistant, making it a good choice for outdoor use
