General Contractor Practice Exam

When planning a rough sawn board to the final dimensions, which of the following is not correct?

1. Feed the board into the planer with the grain

2. Feed the board into the planer across the grain

3. Ensure the board is straight before planning

4. Set the planer to the correct depth for each pass

The correct answer is: Feed the board into the planer across the grain

Feeding the board into the planer across the grain is not a correct practice. When planning rough sawn boards, it is important to feed the wood with the grain. This technique minimizes the risk of tearing out wood fibers, which can occur when the planer edge runs against the grain. Feeding with the grain helps to achieve a smoother finish and maintains the structural integrity of the board. Being mindful of the board's direction in relation to the grain ensures that the planing process enhances the wood's characteristics rather than damaging them. Understanding how grain direction affects the outcome of the planning process is crucial for achieving the desired surface quality in woodworking projects. Other aspects, such as ensuring the board is straight before planning and setting the planer to the appropriate depth for each pass, contribute to successful and efficient planning. A straight board is essential for consistent thickness throughout, while the correct depth settings prevent excessive removal of material, which can lead to uneven surfaces or stress on the planer.
