Hi Rob No I do not thing the nail would do the trick, do you know anyone with a Oxy cutting set. I have cut up plenty of drums and the steel is thick to withstand the oil being stored inside and the rough handling these drums are subjected to. For there is a scriber you clamp to the oxy set just put that in the centre and move the oxy cutter around to cut out the circle. If you are going to use an oxy set be careful there is no residue inside which is inflammable. We used to cut the bottom and tops of these drums up and weld them together to form a long vacuumed tube to suck the coal dust from the coal face when they were extracting coal. We had a vacuumed pump at one end and it worked great. If you could find a can or the bottom of a container slightly smaller than the required diameter and screw it onto the lid then you could use and angle grinder held against the can as a guide. Or mark out the circle centre punch it and split it into 4 using an angle grinder and cut around using tin snips feeling the centre punch marks as a guide once you have a quarter section removed then it becomes easier. Do you know a plumber close by who I am sure would have hole saws on hand that you could borrow. Let us know how or what method you used. ray

Do you think this nail cutting thing would work for that?? Also I do have a router and could there be any way I could use that??

Just revolve it around until you cut through the metal if it becomes dull use another sharp nail. You can get metal cutting blades for a Jig Saw and circle cutting tin snips also nibblers if you have a compressor. Also there are things called trammels which have points both ends which boiler makers use for marking out circles. But for a one off cut try the wood and nail trick. What you did not say is how thick this sheet metal is you are trying to cut. If it is really thin like sheet copper you could use scissors.
