Chris C
Using a miter saw with a "toothed" blade is more than scary C it's the kind of thing that makes statistics. There is absolutely no SAFE way to do it. The problem is the way the saw blade's teeth want to grab the edge of the tubing once you've managed to break into the inner walls.
You CAN use the chop saw C but you have to use the carborundum blade C made especially for cutting metal. These blades are completely circular C and do not "catch" and shred the tube C like a toothed blade will.
My preference for cutting aluminum tubing is my Makita hand grinder C with the 1/16" thick "cut off disc. This is relatively safe C and very fast C when compared to a hack saw or jigsaw.
The cheapo discs last very little. The brand name discs last a long time. You WILL get what you pay for!!! (Harbor Freight sells 10-packs for a few bucks. For the same price C you can buy 3 decent brand name discs that will outlast the 10-pack.)
Since we are on the subject of cutting metal C never C never C never (!!!) cut this stuff without ear protection. Take it from a deaf basturd C who's listened to Skil Saws whine for decades C these tools will take their toll on your hearing!! My hearing is about 40% of what is was when I was younger.
While we are at it. Eye protection. Same as hearing!!!!! Never cut any metal without decent eye protection. Last year C I had to go to an eye doctor C and have a metal sliver removed from my eyeball!! After 3+ weeks of the agony C I faced the music and got it removed. I was hoping it would come out on it's own........nope! (I had to this 35 years ago C but it was a wood splinter back then.)
I thought my glasses were good enough. They weren't.
Here on the Kolb list C we want to always use protection!!

Put a plywood (fine tooth) blade in backwards and it works great for that.

Actually if you turn the blade around backwards it cuts all manner of metal like butter. Use any old blade. Max Nix.
