got that wolfgang, however the damm plug has blown, was hoping that a kenwood chef would serve as a good substitue ( saw that on Blue Peter once) any tips though on how to get it to reach near light speed without it becomming infinately heavy?, as this part always seems to baffle me. I'm damm sure E should not equal MC squared, as it is such an inconvienece with experiments. Thanks for help!!!!!!!!
Perhaps the metals you're working with aren't base enough. A combination of zinc and tin, without any admixture of copper, might be best. Try to get some of those horrid old, grey coins =- usually with a hole in them - at the bottom of coin dealers' "any for 10p" boxes. Failing that, go to one of the world's main sources of base metals, eg Nova Scotia or Australia, and mine for the ore yourself. The following websites may help:

lol, thanks for that, love this site so many helpful folk in it. Heading off to the mine in Oz for the avo, will let you all know how I get on, determined with this one guys........
Gerry Baby...surely this is easy peasy (well for a woman anyway...we do it all the time)..go to the bank and take out as much money as they will let you (and you can carry) in coin..so there's your base metal - dump it in a wheel-barrow and take it to the nearest jeweller and exchange it for some gold - job done :o) ..yes, I know there's a drawback in that shopkeepers are not legally obligated to accept this much coin but no one in their right mins would turn down a barrow load of cash!!
Have to thank all you guys for your help, just wondering if you can all lend a hand to help me with the teething probs I am having with another wee project. I will post it as a new question though. god bless you all
