Which of the following statements about an 8-point saw is not true?
an 8-point saw makes a finer cut than a 12-point saw |
|
an 8-point saw makes a rougher cut than a 12-point saw |
|
an 8-point saw has eight teeth per inch |
|
an 8-point saw makes a rougher cut than a 6-point saw |
Saw blades are described by the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make.
Which of the following saws would you use for creating a curved cut in wood?
coping saw |
|
crosscut saw |
|
back saw |
|
hacksaw |
Wood saws are categorized by their teeth shape and the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.
Which of the following statements about drill bits is not true?
drill bit size maxes out at ¼" for woodworking |
|
drill bits are primarily left-handed |
|
drill bit size maxes out at ½" for metalworking |
|
drill bits are primarily right-handed |
Drill bits remove material to create holes. They come in a variety of sizes, maxing out at ¼" for woodworking and ½" for metalworking. The majority of drill bits are right-handed which means they cut while rotating in a clockwise direction.
What is a framing square used for?
marking lines at a right angle |
|
measuring thickness and irregular shapes |
|
measuring length around corners |
|
ensuring that surfaces are level |
Rulers are used to both measure distance and to draw straight lines. Tape measures are flexible rulers made from cloth or metal and are useful for measuring longer distances and in tighter spaces. Both rulers and tape measures provide similar accuracy, commonly down to \({1 \over 16}\) or \({1 \over 32}\) inch. A steel framing square is made up of a shorter ruler (tongue) and a longer ruler (blade) that meet at a 90° (right) angle. A framing square is often used by carpenters when framing stairs and roofs.
The primary difference between a claw and a ball-peen hammer is which of the following?
their handle shape |
|
their size |
|
their non-striking end |
|
their striking end |
The most common striking tool is the hammer and the most common variety of hammer is the claw hammer. The claw hammer has two ends, one to drive nails and one to remove nails. Ball-peen hammers replace the claw with a rounded end that's used to round off the edges of metal pins and make gaskets.
