SHOP SAFETY
This is the main reason safety glasses are required in sheet metal work.
Protection from sharp edges and flying debris
This tool is used to create bends at specific angles in sheet metal.
Sheet metal brake
This is the FIRST step when beginning a sheet metal project.
Laying out measurements
On a blueprint, a dashed line usually represents this.
A bend line
Why should rivet holes be evenly spaced?
To improve strength and appearance
This situation is MOST unsafe in a sheet metal shop.
Reaching under a shear blade
This tool is BEST used to make straight cuts in sheet metal.
Foot-operated shear
Why is bend order important when forming a box?
Incorrect order can block later bends
What is the main purpose of laying out a project before cutting?
To reduce mistakes and wasted material
What tool is used to mark hole locations before drilling?
Center punch
Why should sheet metal always be deburred before bending?
To prevent cuts and cracking
This tool permanently fastens sheet metal pieces together.
Rivet gun
Why is test-fitting important before final assembly?
It prevents permanent mistakes
What tool is commonly used to create precise perpendicular layout lines?
Combination square
What problem can occur if rivet holes are misaligned?
Crooked or loose joints
Why must sheet metal be clamped before drilling holes?
To prevent the material from moving
This tool adds strength without significantly increasing weight.
Bead roller
Which process usually comes LAST in a sheet metal project?
Final finishing
Why is layout accuracy important before cutting sheet metal?
Errors cannot be fixed once material is removed
Why should parts be clamped before drilling for rivets?
To keep holes aligned
What can happen if rivets are installed without parts being tightly clamped?
The rivet may not set properly
This tool is used to create inside curves by compressing metal.
Shrinker
Why should bends be checked for squareness during assembly?
To ensure parts fit together correctly
Why is it important to follow the print when forming sheet metal parts?
So all parts fit and assemble correctly
Why should final riveting be done only after checking fit?
Rivets cannot be removed easily
