Hi Bird,
¡°Maybe I¡¯ll try something lighter gauge as you suggest, Imran.¡±
If by that you mean HVAC fitting to connect then yes. If you mean spiral pipe than that is not what I suggested. I like the heavy gauge pipe I got from Rockler. Like others have suggested just screw or rivet. I also used AL tape to seal and yes, it is hard to remove.
Definitely pre drill. I even connected some cast AL blast gates to spiral pipe with screws.
