Final answer:
The sawing pattern called plain sawing (or flat sawing) produces wider boards that are more likely to shrink or warp, rather than the type of saw used. It is the methodology, not the tool, that affects the board's stability and size. The role of tools like a two-person crosscut saw is more significant in tree felling than in milling processes.
Step-by-step explanation:
The cutting method that produces boards of greater width but is also more likely to result in the boards shrinking or warping is not directly related to the type of saw used (e.g., circular saw, table saw, band saw, scroll saw), but rather the method of cutting the wood from the log, known as the sawing pattern. In the context of tree cutting for lumber, a two-person crosscut saw is more about the actual felling of a tree rather than the subsequent processing of its wood.
However, the sawing pattern that typically yields wider boards and is thus more prone to warping is the plain sawing (also known as flat sawing) technique, which slices through the log in parallel cuts. This is in contrast to quarter sawing, which produces more stable but narrower boards. When considering the stability and size of lumber produced, it's not the tool that is the primary determinant, but rather the cutting methodology applied to the raw log during its initial milling process.
