Describe the procedure of establishing a timber post and barbed wire fence.
- Clear the fence line (1m wide)
- Measure and mark points where holes are to be made (4 -6m interval)
- Determine the position of corner and gate posts
- Dig holes 60cm deep for intermediate posts and 90cm for corner and gate posts.
- Place posts upright in the holes
- Mix and place concrete in each hole and firm it
- Reinforce corner/gate posts by use of struts/brace
- Nail strands of barbed wire onto the posts using staples while stretching using a wire strainer at 30 – 50cm interval
- Fix the lower strand of wire first at 10cm from the ground and use it as a guide to fix the next.
- Intertwine droppers across the wire strand at 25cm intervals.
