Need to know how to go about cutting up a semi-trailer frame

Man, I would LOVE to use a Partner saw/K12/Demo saw. When I was in the fire department, we still used those for many-a-task and they made quick work of quite a few things. Cash is tight, so that’s not an option. We had a bullet (not the kind you ladies might use) as well and that was great for roofs, as MT mentioned.

But we have to start small. My partners went out to check the project to do a size-up and gather information for an estimate. There's also an aluminum pool we'll be pumping out and taking down. Cash is tight at the moment and the only cutting tool we have is my Harbor Freight angle grinder. Great little tool, but this is a liiiiiiiiiiiiittle out of its league. We’re going to go a step up and get a circular saw and some metal cutting blades. We’ll be scoping them out at Home Depot tonight.

Project should start Saturday morning. Will keep you guys updated.
