Answer 1

Based on English and International (Metric) System of measurement.

1. Measuring Tools - linear measuring tools to establish length for distances from 16th of 1” up to 300’. Tapes over 100’ usually subdivide in 10ths of a foot.
   - folding rulers
   - cloth or steel tapes
   - spring lock tapes
   - laser (for rough estimates only)
2. Testing Tools - used to check workmanship and measurements. Horizontal and Vertical testing tools:

• Plumb Bob - vertical reference line
• Torpedo Level - (aka spirit level) used to check horizontal and vertical lines for slope or plumb conditions.
• Laser- avoid eyes, used to layout correct lines and stacks and establish slope.

3. Sawing and Cutting Tools- cut wood, plastic or metal. TPI and saw material hardness variations. Saws for plumbers:

• Keyhold Saw - narrow tapered blade used to cut any shape in wood or Sheetrock.
• cross cut saw - best all purpose saw for wood. Straight cuts across the grain.
• Ripping Saw - similar to cross cut saw except for different type of teeth that are used for straight cuts with the wood grain.
• Back Saw and Miter Box - this pairing is used to make accurate angular cuts so trim pieces will fit properly.
• Hacksaw - used for cutting metal. TPI is determined by the thickness of the metal to be cut.

Other hand tools for cutting metal or wood:

• file - used to remove a small amount of material for careful fitting and shaping. Double cut (rougher) or single cut (aka mill cut is smoother) teeth cutting (mill options). Handle is known as the tang.
• Wood Chisel - 25 degrees bevel used for shaping thin layers of wood.
• Cold Chisel - double beveled edge with much steeper angle than a wood chisel. Used to cut iron steel or concrete. Sometimes used to force flanges apart. Remove mushroom or slivers of metal around head for safety.
