Cutting rectangular ductwork requires careful measurements and the right technique. Use a measuring tape and pencil to mark the cutting lines accurately. Tin snips are excellent for straight cuts on smaller ducts. For more extensive or thicker rectangular ducts, a reciprocating saw with a metal-cutting blade is effective. 

Ensure the duct is well-supported and secure while cutting to prevent wobbling and maintain precision. After cutting, use a metal file to smooth any sharp edges, ensuring safety during installation. 

Choosing the right metal fabricator for your project begins with research. Find a reputable fabrication company by searching for reputable contractors in your area, and then reviewing photos of their previous work, customer reviews, and photos of the company’s workshop.

Once you’ve narrowed down the list, contact the companies to ask about the types of metal fabrication projects they specialize and inquire about guarantees and warranties on workmanship. You should also ensure the company uses high-quality material, and ask about the schedule and turnaround time for your proposed project.

You should not do your own welding unless you have the proper training and experience. Most home electrical systems can only handle MIG welding, which creates weaker bonds than TIG welding and won’t work on certain metals or metal thicknesses. Both welding forms usually require the use of shielding gas, which can be dangerous to store at home. Additionally, welding machines create temperatures of over 3,000 degrees, and the sparks can blind you if you don’t have the proper equipment. As such, it’s usually better to hire a professional welder for your welding projects.

This all depends on the tools you have on hand and whether you’re trying to cut a straight line or shapes. 

The best tool to use for straight lines is either a circular saw or table saw. When cutting shapes, a jigsaw will be the easiest and most precise tool to use.
