Hi Fatboy,
It has been a bit hectic getting everything ready in the lead up to Easter , so not been online for a while.
I thought you might enjoy a little look and a quick explanation of how the 'Waveswinger' works, although it is quite a simple idea, it can be hard to imagine what is going on under the covers. Sorry for the jigsaw picture, but it seemed the easiest way to piece all the images together so you get the full picture as I could not get a full shot in one go.
As you can see there is a central column which has a slight angle at the top, this is the part the gives the chairs on the waveswinger the tilt as it rotates. There is an inner and outer drum that sit over the column, the inner drum is pulled up the column by two wire ropes in the slots either side of the column attached to a big hydraulic ram inside the column, the outer drum which rotates via two hydraulic motors against the inner drum, holds all the frame work for the chairs and decorative panels. When the inner drum is pulled up to the top of the column it follows the angled column to tilt the whole top over but also the inner column is rotated at half the speed of the outer drum in the opposite direction , which gives the ride that classic wobbling top.
I'll run through the build up in my next post.
