Subject: Would my 'gravitron' work?

This idea evolved from the operation of a magnetron (my microwave oven). 
I've heard that, according to the theory of relativity, an accelerating 
object gains some sort of mass, and that a spinning object is a form of 
constant acceleration, and that this spinning object would create a 
gravtational field around it. If this is so, here's my idea: instead of 
spinning electrons around within the magnetron, spin a solid object 
(gravitron). What do you think? (and stop laughing at me!)
