thanks for the tip,but so far most of the aluminum i polish is motorcycle rims,swing arms etc....and would most likely smoke a dremel.
now i know in my previous statement i talked about a flex shaft that kept
breaking on me,i found one on the same companies web sight for 29.99 and it is heavy duty,i am very impressed and take back what i said!

it bolts onto a 1/2 buffer shaft and apeears to kick butt
