Barrel steel is not particularly hard to cut with a hacksaw, especially with a NEW blade and it vised up at the right working height, which is actually a bit higher than most waist heights; ie, about between bent elbow and waist for me. This gives great control, so with a properly leveled, straight and squared/marked barrel and cutting on only the forward strokes (you do have the teeth pointed forward), steady and even, it goes pretty quick and you can keep to the line well. You can use the wood guide block or angle iron too, or just keep eyeballin' it to the mark. That hole in the middle requires no cutting

BTW, my hacksaw cutting got ever SOOO much better when I spent the few 'extra' bucks on a real, heavy duty HS frame at our Farm&Fleet.; puts those chinzy hardware store cheapies to shame.
Now I suppose there is some 'Zen' thing to doing it this way, its just you the barrel and your consciousness transferred to the blade cutting teeth, but hey, its all in good, careful workmanship
