Come off the registers and it'll be alot easier and cheaper. If not , yellow is very correct, make a perforated outline of how you wanna cut the whole with the drill. Also you'll need some aluminum duct work tape to get a good seal on it, or you'll be losing pressure and energy efficiency. Also cut on the inside of your line when you mark it off with a sharpie, it's always easier to flare the end of the duct fan with tin snips for a tight fit than cut a whole bigger than a blowed out pornstars snatch. You're headed in the right direction! Thats alot easier with it run up in the attic like that, that's why I did mine off the registers cause i'd have to crawl my fat ass under the house, and That's not gonna happen. I killed over 30 Black Widows cleaning out the garage setting mine up, no fucking way i'm gonna get bit under the house!
beautifUiI, wait and see wat kind of budding you wiII get on that one.
