I own most of the tools and would hate to buy a new one for this project but
take your best shot at the best way and tool to do this and I will go from
I have not actually measured it but I think the main trunk line I need to
cut is 12x18, might be 12x24. Standard gauge metal HVAC duct from 40+ years

going to be a b****
but I can do it once if I must. Most likely, I want to
return the duct to its original position after the project is completed.. I
might choose to step it up to make it easier on the next fat guy. But that
part I can figure out.
I can't unzip it at the seams without a lot of digging in 60+ year dried
dirt as the next seam is resting on the ground. Hey, I did not do the

from. Go ahead and make your fat guy jokes if you must. Paybacks can be
