Thanks gents as usual some interesting things to say. I will certainly post some pics as the Gazibog build progresses. We are trying to use as much scrap as we can so we have some old bicycle wheels and chains, an old stainless sink unit, about 25 Imperial spanners that I have donated as I won't buy anything British again sadly, a bath etc. The aim of the Gazibog is to create a wind/water powered sculpture that moves, makes noise and does stuff like wave flags etc. The people who come to the day service are mostly visually and hearing impaired and para or hemi-plegic wheelchair users so we need big, noisy experiences and being made outside means we can let our imaginations go wild.
Don't show too much interest though or I will campaign for a Thumper Club charity event where all you talented people come to my day service and do a collective build. Now there's a thought!
