[QUOTE="s-band, post: 995248, member: 407744"] Thanks. I followed aceb's lead but I think his may be more precise as I have not strung it. Yes, it's a mixture of Waxoyl and grease I liked the idea of a water tank as ballast (Terryl's?) so may try that if I leave it outside for any length of time. I saw this [URL='http://www.ebay.co.uk/itm/122194654344']airport cargo/pallet trailer with rotating table | eBay[/URL] and thought it would be a possibility especially as it has a turntable for azimuth. I'm not sure what I'll do with it once I have enough time to do the big dish. I thought of making it az-el. The el is easy but for az I was thinking a pole could be used as a bearing vertically through the centre of the pallet and the other end of the pole would go into a socket in the ground. Another pole in the ground could hold the fixed end of a jack with the moving end attached to the pallet. If that were done it would be better to have fixed wheels as opposed to castors. Crazy idea? Probably would not last long and I doubt that I'll do it. The castors are fine on concrete but are not ideal here as they tend to sink in the ground so I need to keep away from the swampy areas of garden. [/QUOTE]
