135. 6th, 7th & 8th November 2010 Compagnes Drift Mill. 2nd Open Gardens Weekend and Sifter
With the extra load from the working elevator, we’re noticing we need more power, and therefore, more water. The amount of water is governed by the sliding gates in the weir at the dam, added to any overflow (which diminishes as the water below it is consumed during the day); the height of the sluice gate and the opening in the wooden launder directly over the water-wheel. All these were arrived at by pure guesswork, and we’re only now noticing limitations.
I can easily make more slides in the weir. Only two of the five sections have slides built in. I can easily add an extension to the height of the sluice. On the Sunday of the second Open Gardens weekends, we ran as close to the sluice overflowing as we ever have.
