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 makes a rougher cut than a 6-point saw |
|
an 8-point saw has eight teeth per inch |
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.
These tools are called:
planes |
|
chisels |
|
rasps |
|
files |
Wood chisels are used to shape or smooth wood surfaces. They come in a variety of widths and can be used with hand power or tapped with a mallet when deeper cuts need to be made.
Which of the following saws would you use if you're cutting wood across the grain?
hacksaw |
|
ripsaw |
|
crosscut saw |
|
back saw |
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.
You are using a hacksaw to cut a Class 8 bolt. What is the most appropriate TPI for your saw blade?
10 TPI |
|
2 TPI |
|
18 TPI |
|
8 TPI |
A Class 8 bolt is made of very hard metal and larger TPI saw blades are most appropriate for very hard metals.
The primary difference between a standard level and a bullseye level is which of the following?
a bullseye level can measure across two dimensions |
|
a standard level has only one bubble to center |
|
a standard level can measure across two dimensions |
|
a bullseye level has only one bubble to center |
Levels utlize a fluid-filled tube containing a bubble that is centered when the surface is horizontal (level) or vertical (plumb) along the direction of the tube. While a standard level can measure along a single dimension, a bullseye level is circular and can indicate the levelness of a two dimensional plane.
