Lowered grid

The grid was constructed from 2 single purchase bars and 3 double purchase bars; 11, 14, 15, 16 and 21. These were cross-braced with a number of lengths of scaff bar, attached with right-angle and swivel clamps (19 in total). We would have liked to have used entirely right-angled clamps, apart from the 4 used to connect the 2 lengths which were not at right angles to the counterweight bars. However, we were unable to find enough.

We also initially planned to connect another 6m bar to the far SR end. However, we felt that the grid was rigid enough without, and that the clamps could be better used elsewhere.

Bar weights were worked out as follows:

Bar 5 (LX): 7.68kg + 10% = 8.5kg. Therefore, 1 weight.

Bar 11 (Grid): 68.11kg + 10% = 75kg. 6 1/2 weights. However, when the bar was weighted, another 4 weights were added. 10 1/2 weights.

Bar 14 (Grid. Double purchase): 106.35 + 10% = 117kg. 19 1/2 weights. Only 19 weights were ever put into the cradle.

Bar 15 (Grid. Double purchase): 69.96 + 10% = 77kg. 12 1/2 weights. Only 12 weights were ever put into the cradle.

Bar 16 (Grid. Double purchase. Identical to 14): 117kg. 19 1/2 weights -> 19 weights.

Bar 21 (Grid. Identical to 11): 75kg. 6 1/2 weights -> 10 1/2 weights.

Bar 27 (LX. Identical to 5): 8.5kg. 1 weight.

Full blacks were hung on bars 2 and 29.
