Chapter 2 Common processes and techniques


                 Universal hard point saw
                 A general-purpose wood saw that is used
                 for lifting and cutting floorboards, building
                 platforms and stillages.
                 May be used for cutting plastic pipes.
                 The teeth have tungsten steel hard points so
                 that they remain sharp for longer.
                 Floorboard saw
                 A saw made specifically for cutting and lifting
                 floorboards in position.
                 It has teeth on the end of the saw for cutting
                 through floorboards while they are still in
                 position.
                 Pad saw
                 Often called a ‘keyhole saw’ or ‘drywall saw’.
                 A long, narrow saw used for cutting small,
                 awkward holes and shapes in building
                 materials, such as wood and plasterboard.
                 There are two types of pad saw: the fixed-
                 blade type and the retractable-blade type.


                Grips and wrenches
                Grips and wrenches are tools that are used almost every day by plumbers. They
                are essential tools for tightening and gripping. There several different types, as
                described in Table 2.6.
                  Table 2.6 Types of grips and wrenches used for plumbing
                 Water pump pliers
                 These are a plumber’s general-purpose
                 grips. Three pairs should be available in the
                 toolbox: 175 mm, 250 mm and 300 mm.
                 Footprints
                 Another general-purpose grip used by
                 plumbers for tightening fittings and unions.
                 Care should be taken when using these
                 as they can easily trap fingers if used
                 incorrectly.
                 Stilsons
                 Stilsons are used when installing low carbon
                 steel pipe.
                 They are available in many sizes, ranging
                 from 10-inch to 36-inch.
                 Basin wrench
                 This is used for tightening and loosening tap
                 connections in hard-to-reach areas such as
                 behind wash hand basins, baths and kitchen
                 sinks.
                 Mole grips
                 Mole grips are a locking type of pliers.
                 They give a high clamping force and can be
                 locked to allow hands-free gripping.
