Which of the following types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?
coping saw |
|
crosscut saw |
|
hacksaw |
|
rip saw |
Wood saws are categorized primarily by their teeth. 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.
When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).
even |
|
odd |
|
low |
|
high |
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.
Which of the following saws would you use for creating a curved cut in wood?
hacksaw |
|
coping saw |
|
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.
What is a caliper used for?
measuring thickness and irregular shapes |
|
transferring distances between objects |
|
ensuring that surfaces are level |
|
making perfectly vertical lines |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
