Instruction example 3.1. Nameplate

To practise lengthening of sheet steel by hammer blows with the hammer pane, flattening of a surface section by a sledge and simple marking.


General-purpose constructional steel sheet strip (340 MPa)
Thickness: 2 mm
Width: 15 mm
Length: 80 mm


Hand tools

Hand hacksaw or lever shear, engineers’ hammer (500 g) scriber, centre punch, 4 mm dia. drill, bastard file 200 mm (flat), sledge, marking punch (letters).

Measuring and testing tools

Steel measuring tool


Surface plate, vice, flat nose plier or pin vice

Required previous knowledge

Reading of drawings, measuring and testing, marking and punch-marking.

Sequence of operations


1. Arrange the working place, prepare the working materials.

- Check for completeness.

2. Check for initial dimensions, otherwise scribe and cut the sheet strip to size, scribe the 12 mm size

-Stage (1)
Use the hand hacksaw or lever shear.

3. Check for initial length, grip the scribed end by means of flat nose plier or pin vice and hammer with the hammer pane steadily towards the other end.

- Stage (2)
Use vice anvil or surface plate as support.

4. Straighten the sheet strip, check for size; if necessary, repeat operation 3.

5. Scribe the area for the name according to the number of letters and flatten it by means of hammer and sledge.

- Stage (3)
Clamp the sheet strip adequately!

6. Punch the name.

- Further markings may be applied at the rear side of the sheet.

7. Final inspection.

- Dimensions, appearance.


Produce the bore hole and radius according to the size specified under supervision of the instructor, hammer all edges with gentle hammer blows (of the pane) obliquely.
