The __________ is an initial shallow saw cut made as a guide to prevent the saw from slipping sideways on subsequent more powerful cuts.
guide |
|
kerf |
|
channel |
|
groove |
When you start sawing by creating a kerf it will help prevent the saw from slipping sideways when you begin the power strokes that do most of the cutting.
Which of the following saws would you use for creating a curved cut in wood?
coping saw |
|
hacksaw |
|
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.
A joint created by welding is __________ the original metal.
weaker than |
|

|

|

The joint created by welding is as strong or stronger than the original metal.
When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).
odd |
|
high |
|
low |
|
even |
Blades with more and smaller teeth (high TPI) cut harder metals more effectively while blades with fewer and larger teeth (low TPI) cut softer metals more effectively.
Screwdrivers are most broadly classified by their:
torque |
|
length |
|
width |
|
tip |
Screwdrivers come in many different handle, shaft, and tip configurations for use in a wide variety of applications. Screwdrivers are classified by their tip which is shaped to fit a corresponding screw head. Common tips are slotted (flat) and Phillips (x-shaped).
