The depth of cut for a jointer is determined by adjusting the:

• front guard.

• front infeed table.

• rear guard.

James measures and marks a board correctly. If he saws on the waste side of the line and leaves the line, the size of the board will be:

• the appropriate length.

• longer than needed.

James saws on the waste side of the line, which means he removes the material on the side opposite to the marked line. Therefore, the board will be cut to the appropriate length, as he leaves the line intact.

When Sam uses a file to sharpen a tool, he should reduce pressure on the back stroke because files:

• break when pressure is used on the back stroke.

• break when pressure is used on the forward stroke.

• cut only on the back stroke.

• cut only on the forward stroke.

Answer explanation

Sam should reduce pressure on the back stroke because files break when pressure is applied during this motion. Files are designed to cut only on the forward stroke, making it crucial to avoid pressure when pulling back.
