In this section we will show different methods and tools for cutting through a container. It is not to be considered an endorsement or the best way to cut out your openings. It is always best experiment to see what will work best for you. For us an angle grinder worked well for starting the holes for the saw blade cuts. We also used a drill to pilot a hole to start a cut.
A Jigsaw worked well but the blades dulled quickly and was kind of slow. It is worth the investment to buy a higher quality a metal cutting blade.
Reciprocating Saw or Sawzall with a “Edge” blade worked very well had more power and worked faster.
The metal gauges in a container varies so we recommended different blades for thinner the metal sidewalls with 20-24 teeth per inch, or try a medium thickness blade for between 10-18 teeth per inch, and for very thick metal, like the square tube or flooring beams a blade with around 8 teeth per inch will work better.
We used an angle grinder to smooth out the sharp cut edges.
