Building a fake handheld minigun...

[Gunmaster45]

Before I get ragged on for the obvious impracticality of a hand-held minigun (I know, I know), I thought I'd talk about how I plan to make a fake hand-held minigun to put in a movie I'll be making soon.

How do I plan to make this? A black leaf-blower (out of commission after years of service), and metal tubing strapped to it for barrels. Depending on how it'll look I might chop off the plastic house part so the barrels cluster closer together, although this will be harder to mount properly.

Any suggestions how to do this so it looks best? (it'll be more appreciated than less than constructive critisism. )
