Instruction example 3.4. Copper Bit of a Soldering Iron

To practise widening of copper by hammering with the hammer pane.


Round stock of copper
8 mm diameter, 120 mm length


Hand tools

Engineers’ hammer (500 g), smooth-cut file 200 mm (flat)

Measuring and testing tools

Steel measuring tool, protractor.


Surface plate, vice, clamping jaws for round stock.

Required previous knowledge

Reading of drawings, measuring and testing, scribing

Sequence of operations


1. Arrange the working place, prepare working materials.

- Check for completeness.

2. Saw round stock to length.

- Stage (1)

3. Hammer to (60 degrees’) angle in vice according to size specified.

- Stage (2)
Clamp round stock in clamping jaws for round stock.

4. File 2 x 45 degrees in vice.

5. Hammer both sides of the flanks of the soldering iron bit with the hammer pane.

- Use surface plate or vice anvil as support.

6. Smooth the flanks with the file.

- Stage (3)
Make sure that the specified size is maintained.

7. Final inspection.

- Dimensions, appearance.

To continue practising, if necessary:

Produce soldering iron bits of required diameters (depending on the sizes of the soldering irons used in the workshop).
