Cutting up iron

When all else fails, Use fire...... This is where a cutting torch comes in handy.

If the question is just the fit and not the weight, why not lay it across the top and strap it down? Or at an angle or on its side? But yes a torch will go right through it and the set-up is useful if you do any welding anyway.

A Plasma cutters great for this sort of work. One with its own built in air compressor.
Thats if you intend do be doing a fair amount of work.

Otherwise its either a oxy/acetylene or oxy/propane gas cutting torch.

If you use a angle grinder it would need to be a 9 inch cutoff disc or a larger gas powered demolition cutoff saw.
You can rent a demolition cutoff saw just for one job. If the jobs recycling the steel it would be worth it, or if you are getting paid to remove it.
For the price of scrap steel it would have to weigh a lot.

Find out the hire price anyway, that info is handy & always gives you another option.
[ After edit ] you might as well get the hire place to quote the rental on the plasma cutter too.

Maybe you can line up a friend with a cutting torch and kick him a few bucks ? It's a bit of an investment. Can't remember the exact amount, but i think it was at least 600.00$ spent to for the torch, regulators, welding mask, tanks, and first year's tank lease. The tank lease is another 100.00$ per year. It's not bad if you use the torch on a regular basis in your work and you're making money with it. Otherwise, it's hard to justify the expense.

It would be a lot cheaper to hire in somebody with a torch to do the cutting work for you.

Maybe it's just one of those sucky jobs that you just have to muddle through. You get bogged down with em' from time to time when you're scrapping. You just have to take the bad with the good and resign yourself to the fact that it's gonna take awhile to get through it. The harder you push it .... the more the job fights you. Tools get destroyed and people get hurt.
Just relax and go with the flow.

Stop ... take a few minutes ... and think it through. Use your noodle and not your back. Make a plan. A cut here and a cut there. Break it down into bite sized pieces.

Question: Are you dealing with steel -or- Iron ?

Big difference between the two. Iron is hard and brittle. Steel is softer and easier to cut.

You would definitely want the blue dragon for iron.

You might try a 7 1/4" circular saw with a metal cutting blade set to just the right depth if you're cutting steel. ( For 1/4" steel plate set it to 3/8" or 1/2".) That way the blade is peeking out just a bit below the thing you're cutting. Don't try to cut it all at once. Instead, make a series of score lines, each one getting progressively deeper till you're all the way through.

Support the work that you're cutting. That way it doesn't fold in and bind your blade. Maybe even put just a bit of upward pressure so that the metal parts as you're cutting it.

It would be pretty much the same thing with a sawzall and some good metal cutting blades. The job might go a bit faster that way cause you can cut all the way through in one pass.

The main thing is : Don't bind the blade. It will ruin your blade and damage whatever tool you're using.

Use finesse not force.

Use a trailer.

I was able to cut - slowly with my 4 1/2 angle grinder (my old 7" angle grinder is one that I killed being impatient) and Sawzall with the torch blade. It's steel not iron, and the table/platform base is diamond plated steel sheet and is stronger than the steel in the legs and supports and took a long time to cut. Thanks for the suggestions and advise.

It's funny I now recall telling them "no" several months ago on taking these items because of their size and time required to cut etc... Even with a trailer one of the items would have still required a little cutting. Not sure how I got talked into taking them anyway - but I said I would do it this time so I didn't back out.
