hi ed,
       sorry to butt in but i have had many emails with both antonio and 
john about there metal spinning and they have been very helpful! and i have 
now spun a fair bit of aluminium.
a good tip i got from steve rodway of legion electronics was to rub normal 
hand soap on the back of ali to be annealed then heat slowly on other side 
until soap turns black. this worked a treat and until then i really 
struggled with spinning properly. also another thing we discovered was a 
really good solid former. steve made a nice steel backplate to stop the 
former flexing and this improved things no end
hope this helps
