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

Well I have done a few of them, there is a lot of work involved labor, trash (wood) I would have to charge the customer $300.00 for the job that would cover your labor and torch, gas / oxygen, there is not as much weight there as you may think.

You can rent a torch with all the tips and gauges, don't buy one for this job it will cost you more for the set up than you will net.

1956 is absolutely right, there is not as much weight as one might think.

Based on the condition of the steel, the rust is going to be a pain to cut with a torch. Most burners know that the gas of a torch heats the metal and the oxygen does the cutting. The rest of the recipe that few consider is the fuel is actually the metal you are cutting. Rust is a poor fuel for a torch. You can cut rust and even cast with experience, but it is time consuming. Unless you plan to do more of this type of scrapping, I would not buy a torch. The expense and learning curve will not make it worth it. My recommendation would be to use a Quickie Saw (also called a demo saw) with a cutting wheel for metal. Cut in pieces that you can handle. If you have equipment you can make less cuts.

If this was my project, I would burn the wood after a good snow fall. Make sure you notify the neighbors prior to doing it. Then using a skid loader, winch, and trailer it would be loaded in two pieces and hauled directly to the yard. I actually did one because it served as weight on top of several grain bins hauled to the yard. Good luck and let us know how it goes.

Sorry Mechanic. You posted while I was on the phone.

My suggestion would be as patriot said a gas demo saw . You can rent one At homedepot or Etc. Or a big angle grinder .

Matty,

I did a pop up camper and a 2 axle tow behind camper last fall and this spring. Pain in the ass disposing of all the non metal. As others have said, not that much metal for the effort. I used a trusty sawzall, but a torch or gas cut off saw would have been quicker.

I would normally advocate for using a BFH. In this case I agree with the others an suggest a BFS.

Have fun, be safe.

Parter saw?

What is a Parter Saw? I would love to know more about it? Always willing to learn, just slow about learning.

Google image search it I don't know how to copy images on this tablet. Computer down

What I get..



Sirscrapalot - Still prefers the term BFS.

Yup thats it I've heard of the fire department using them so they have to be good.

Partner saw is just another name for a gas demo saw with the round disc blades. Most people here are referring to it as a gas demo saw.

I did 12 years on a fire department. We had these, but with newer technology they got used a lot less. We used them on car roofs, but an air chisel was better. Lighter and didn't throw sparks. We used them for venting roofs at a fire scene. Then we got specially designed "chain saws" that had depth gauges / safety covers and carbide bullet chains. These suckers would fly thru any roof. Nails were no match. We did have to replace a few chain teeth once in a while
