Have a used propane tank (properly purged) to hack for a smelter. Tried cutting it in half with a Sawsall - MY gawd the thing is hard. hence the question.
I started the cut just above the weld seam. After attempting this, and making nearly no progress... Do I need to cut along the very middle of the weld seam? Is this easier to cut along the seam than the tank case itself? Thanx
