1 Form gauges are used to check:
a part that has been formed turned
the shape of a form tool that is being ground
the shape of a moulded or cast part
the shape of pressed or stamped sheet metal parts
2 Radius gauge
3 Determining the pitch of a metric ‘V’ thread
4 Feeler gauge used for measuring narrow slots or setting gaps such as valve clearances
5 To check the form of the component
6 The gauge is bent because it is being pushed through the gap instead of being pulled through it
7 Too large
8 Checking the thickness of sheet metal, paper, cardboard or plastic.
9 Because the form is different.
10 The ring spanner grips on all six sides of the nut instead of only two sides.
11 A socket spanner, universal joint and ratchet.
12 The socket spanner used on an impact wrench has a heavier wall thickness than a standard socket spanner.
13 Left side is a Posidrive Right side is a Phillips
14 ‘A’ is the correct direction.
15 A ‘C’ spanner
16 An open ended spanner can be used on the blade of a square bladed screwdriver to get a greater tightening or loosening effect.
17 A tension wrench is used when it is necessary to tighten a nut or bolt to a specific torque.
18 If the scriber point is overheated it will loose its hardness.
19 Trammels would be used when the radius being marked out is larger than the dividers can open to.
20 The dividers must be set to 40 mm
Set the fixed leg of the dividers on the 10 mm line and open the dividers until the moveable leg fits in the 50 mm line.
21 So that the scriber will not chatter of vibrate while scribing the line.
22 The scriber should be set parallel with the mast with the bent end lower than the top of the mast.
23 Clean and lubricate before storage
Store in their own compartment
Prevent contact with other tools
Store in a non corrosive place.
24 Repair the tool if you are qualified
Replace the tool if it is too badly damaged
Tag the tool if it is to be repaired at a later date
