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.
Yes, you can cut plexiglass by hand using a sharp knife or blade (utility knife, box cutter, glass cutter, etc.).
Cutting round ductwork requires precision and the right tools. A duct cutter, specifically designed for circular ducts, is ideal. First, mark the cutting line on the duct using a measuring tape and pencil. Then, position the duct cutter's blade on the marked line. Apply steady pressure, rotating the cutter around the duct. The sharp blade creates a clean, precise cut. Alternatively, a reciprocating saw with a metal-cutting blade can be used for larger round ducts. Ensure the duct is securely held in place while making the cut to prevent slips and maintain accuracy.

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.
