Seriously, how does this video have 2 dislikes? Thank you for the help. I have never worked with duct and this gives me the info I need for a DIY project I am doing. Thank you again. and keep up the good work!
Byy marking the jagged edge of the collar you are making an incorrect hole size that creates the potential for leaks and injury, also lack of airflow. May i suggest you use a divider to make a correct circle, or bend out all flanges on the collar and mark from the inside where you will now have a smooth circle marked out. I know someone always hase\ something to say but I thought if you were to take the time to film this you may want some insight as to the correct method. Good job by the way.
James Chaffin Thanks for the input. If a person has dividers that is good advice. If you have limited resources and tools, this will work. I must say, I do not agree with you about the air flow issue. But again, thanks for the input!
Hey man, much better way for a circle in my honest opinion. Okay, in example you've got a 6" airtight. Sure, you could trace the circle, but you could also grab, say a piece of hanger strap, drill two screws 3" apart on the hanger strap. Remove the screws. Find the center point of your circle and screw down one hole onto it, place your sharpie in the other hole and just rotate it. You should end up with a perfect 6" whole. Only tools required, drill, and tape. You don't need a hanger strap either obviously, just used as an example.
