I'm remodeling a bathroom in our house and I'm installing a new and better exhaust fan. I need to cut the existing 3" sheet metal stack to fit the new fan. This is an in-the-wall unit.

How would you cut the sheet metal???

I have a reciprocating saw and one of those oscillating saws like the Fein. Maybe I should just use a hacksaw?

I have aluminum wiring in my house. I haven't done a lot of wiring in the house I had most project done by a licensed electrician. I've heard that when joining aluminum wiring to copper I should use Noalox but recently I heard that a special wire nut is needed with wiring aluminum to copper. Would one of you experts let me know the truth.

Thanks!

Aviation snips is what I'd use. I've never dealt with aluminum wire myself.

You'll have to check the bldg code in your area for dealing with Aluminum wire and connectors.

Please do your research, AL wiring does have issues. (Glad I don't have to deal with it) My Mother in law has AL as does my Daughter. The wiring can get very hot if not done correctly.

Indeed. My father's house once burned to the ground as a result of an improper AL-CU connection.
