You don't need to clamp it to make a safe cut, although you need a good fence to hold it against. I have proably cut 1,000 feet of 6061 with a standard chop saw, I've even cut it with a 12" speed square and a skill saw, clamping a 2x4 to a bench to make a fence to hold up against and that method works pretty good too. With all tools, you need to know how to properly operate them etc. etc., while a chop saw or skill saw are fairly easy to operate safely, you can also fairly easily loose a finger or a hand or much worse.
Pic of my raft after proably 60+ days of use of a non-anodized frame, man them marks are huge! You can hardly seem them through the dirt. Plus you have an aire raft, the whole dam outer skin is one big chafe strip, a few marks aint going to hurt it a bit. But of course lots of folks have shiny SUVs with 4x4 that stay entirly on the pavement their entire lives.
I second that, my frame leaves a few marks that get wiped off twice a season when I put on ye olde 303. Nothing to freak out about, though I know some people have their frames powder coated to prevent this, but I can't see it as a big deal.
