Mike what gauge are the spindles? Hollow?
I use a metal abrasive cut-off saw like BC mentioned (or trak saw as we call them) for cutting 12 gauge steel strut, metal TV lift rails, articulated arm brackets, threaded cores etc etc.
All of them look identical and are cheap 150-300 dollars. Get a pack blades, although one blade seems to last forever as they wear down they will heat up the metal more and more and you get a bit of a melted tail of metal as you cut. Using the right amount of pressure is key.
The only problem is that they heat up your cutting material alot, so if the spindles are finished and colour change from heat is a problem then stay away.
I'd love to get a Dry-Cut saw, they cut faster, no sparks, less heat, no colour distortion etc. Only problem is I don't use it enough unless I have a big strut job to warrent the cost (they start around 400 bucks and the blades are expensive).
Here's one:

To cut tubular steel in a shop I worked in we had a big stationary bandsaw which also worked very well. I couldn't see getting that straight of a cut with a hand held guy though.
