2 things about metal pipes.
1. the type of metal matters, if it's copper, or brass you will get lockjaw.
2. metal accualy conducts heat better then glass, and burns the skin worse.

I would have stuck with the first pipe. anyhoo

1/2 piece of duct tape arround the mid section will give you a spot to hold on to. take the screen and make an indent with your pinky so it looks like a bowl, then press it into the pipe bowl very carefuly. sure the tape looks like crap, but you wont burn your self.
