The best way is with a cutoff saw. Cheaper would be a metal cutting blade for a circular saw. Hacksaw is cheapest, but a hell of a workout.
You can also use a plumber's pipe cutter, but it takes longer. Gives you a VERY clean end.--Best way to crimp/flatten the ends of the 3/4” metal conduit after I cut it
Best way is to get a press, next best way is to use a sledge (cheap too, but a hell of a workout)
I flatten almost 3" of my ends, and find that it helps in assembly. (Less critical on a 2V dome.) If using the "blacksmith" method, taper the flattened area to prevent folding and creasing of the metal.--Best way to drill through the ends of the 3/4" metal conduit after I cut and flatten it (without buying a really expensive drill press)
Best way is the drill press. Cheaper is an electric drill with the right size bits, but you'll need to drill starter holes and then probably work your way up.
I drill a 1/8" pilot hole and then follow with a stepped bit and open it up to 1/2". (To accomodate 3/8" bolts.) I use a corded hand drill, which is a little hard on the wrists- Best to take breaks. The stepped bit produces very hot little shards of scrap, so wear long pants.
Regardless of how you do it you'll need some way to anchor the tubing as you work it. A vise would be best.
I bet you didn't watch the burn from YOUR roof!

Seriously though, you're quite right of course - good and bad points about any approach.
