"we assembled a profusion of hoses, pipes and bits into an air-lift. People stood back in amazement asking the same thing ? Would it work? It certainly looked very basic and simple, and Owen?s idea was for it to be just that ? idiot-proof, or was it ?caver-proof??
The whole lot was dropped down the shaft and with a final push on the back Steve disappeared into the murk. He followed the pipe down, got hold of the suction hose, traced it to the end and waited. Then, remembering the air switch was diver-operated, he groped his way back to the base pipe. A final deep breath and the switch was thrown open. It was a perfect launch, with all six yards of the air-lift blazing skywards and a bewildered diver clinging to the tail section being battered to death all the way up!
Owen shook his head sadly and John looked towards the skies. Steve was given new orders and pushed back down the shaft. Again a loud rumbling came to the surface followed by a cloud of bubbles and an air-lift trailing an irate diver.
While Steve had a rest new ideas were thought up. It was decided to attach a bag of weights to the base to prevent launching, while a float on top would stop it sinking too far. Also, by tying the top to the A-frame it was hoped to stop the rotation of the head and keep the debris ejecting downstream instead of everywhere. Other minor problems were encountered and solved. It worked ? that was the main thing." (Steve Ainley, 1986)
