What You'll Learn
Measure and cut the sheet metal
To measure and cut sheet metal for a condensation pan, you will need to take some specific measurements and use the right tools. Here is a step-by-step guide:
First, measure the bottom width and length of your air conditioning unit and add three inches to both dimensions. Transfer these measurements to your sheet metal, marking them clearly with a pencil or marker. You can use a tape measure and a straightedge to help you draw straight lines. It is important to wear work gloves and eye protection to avoid injuries and protect yourself from metal shards.
Next, you will need to cut the sheet metal. Tin snips are a popular choice for DIY projects as they are economical and can cut through softer metals with ease. They are scissor-like hand tools that provide accurate cuts without leaving ragged edges. You can use the standard straight pattern tin snips for making long, straight cuts. If your project requires curved cuts, you can use duckbill-bladed tin snips, which are better for tighter curves. For thicker or stronger sheet metals, you may need to use power tools such as an angle grinder, band saw, or circular saw.
When using tin snips, it is important to open the tool completely and seat the edge of the sheet metal as deep as possible in the jaws. Align the blade with your marked cutting line, ensuring that the metal sheet is stable and clamped down. Squeeze the handles to make the cut, repeating this process along the line until you have cut through the metal. Remember to use small, frequent cuts instead of larger, longer cuts to achieve smoother edges.
If your project requires cutting a hole in the centre of the sheet metal, you can use a power drill to create a pilot hole within the marked circle. Fit the drill with a 1/2-inch or larger metal-cutting bit to accommodate the jaws of the tin snips. After drilling the pilot hole, insert the bottom blade of the tin snips into the hole and cut along your marked circle.
By following these steps, you can accurately measure and cut sheet metal for your condensation pan project, ensuring both safety and precision.

Bend the sides to form the pan
Bending the sides of the metal sheet is a crucial step in forming the condensation pan. This process requires careful planning and execution to ensure a precise and sturdy final product. Here is a detailed guide on how to approach this stage:
First, it is important to understand the properties of the metal you are working with. Different metals have varying ductility, malleability, and resistance to fracture. For example, mild steels and soft aluminums are more ductile and can be bent to sharper radii, whereas bending thick or high-tensile metals requires adhering to a minimum inside bend radius to prevent cracking. Additionally, consider the grain direction of the metal sheet, as forming with the grain requires less force, but bending against the grain can achieve a tighter inside bend radius.
Next, calculate the bend allowance to determine the expansion that will occur during the bending process. This calculation will help you mark your bend lines accurately. The formula for bend allowance is: (π/180) x B x (IR + K x MT), where B is the angle complementary to your desired bend angle, MT is the thickness of the metal, IR is the inside radius, and K is the K-factor, which can be determined from a Bend Allowance Chart.
Before bending, it is essential to make relief cuts along the line you want to bend. These cuts facilitate the bending process and can be made with tools like a laser cutter or a pair of snips. If you're working with thicker metal, preheating the material between 200 and 300 degrees Fahrenheit can make it more pliable and reduce the risk of cracking. However, be cautious not to overheat aluminum, as it can become brittle or melt.
Now, you can proceed to bend the sides of the metal sheet to form the condensation pan. Secure the metal in a vise, ensuring that the bend line aligns with the guide angle of your forms. Use a mallet, preferably made of rubber, plastic, or rawhide, to gently tap the metal and bend it gradually and evenly toward the form block. If you have access to a press brake or pan brake, you can use that instead of a mallet to achieve a cleaner bend. Repeat this process for each side of the condensation pan.
Finally, weld the corners of the pan to make it water-tight. Soldering is generally recommended for light-gauge pans, while welding is more suitable for heavier-gauge pans. Smooth the corners with a grinder, and apply cold galvanizing to each weld to protect against rust and corrosion.

Smooth and weld the corners
When fabricating a metal condensation pan, it is important to smooth and weld the corners to ensure they are watertight and aesthetically pleasing. Here is a detailed guide on how to achieve this:
Welding the Corners:
Firstly, weld the corners of the metal pan together. It is recommended to use a Bessy-type clamp to hold the corners in place while welding. Ensure that each weld is given time to cool before moving on to the next corner. Start with the top corners, and then move on to the bottom corners.
Smoothing the Welded Corners:
To smooth the welded corners, you will need to use a grinder. There are various types of grinders and abrasive discs available, and the choice depends on the desired finish. For example, a flap disc can be used to smooth the weld, but it needs to be the appropriate size for the area being polished.
Fine grinding is a technique that can be used to achieve a smooth and consistent finish. This process involves using a combination of grinding belts and finishing belts with varying grit sizes to step-by-step smooth the weld. Start with a rough prep using a 40-grain belt, then fine-grind with a 120-grit grinding belt and a 40- to 320-grit finishing belt. Finish with a soft contact roller and a medium surface conditioning belt.
Additionally, consider the speed and settings of your grinder or welding machine. Adjusting the volts, wire feed speed, and travel speed can help achieve a smoother weld that requires less post-weld smoothing.
Checking for Leaks:
After smoothing the welds, it is important to check for leaks. Fill the condensation pan with water and inspect for any signs of leakage. If leaks are present, you may need to reweld and smooth the affected areas.
By following these steps, you can ensure that the corners of your fabricated metal condensation pan are both structurally sound and aesthetically pleasing.

Drill a hole for the drain pipe
Drilling a hole for the drain pipe is a straightforward process, but it requires careful preparation and the right tools. Here is a step-by-step guide:
Mark the Centre Point:
Begin by identifying the desired location for the drain pipe on the metal condensation pan. Using a combination square, extend a centre mark on one of the shorter width sides of the sheet metal. From the edge of the sheet metal, extend this centre mark inwards by three inches. Make a mark two inches in from the end with the centre mark. This will be the point where you drill the hole.
Use a Centre Punch:
Place a centre punch on the spot where the two-inch mark and the centreline mark intersect. Using a hammer, make a small indentation at this point. This process is known as "punching a divot" and will help guide the drill bit and prevent it from sliding off-centre.
Choose the Right Drill Bit:
Select a drill bit that matches the desired size of the hole. For a standard condensation pan, a 1/2-inch drill bit is commonly used. If you require a larger hole, start with a smaller bit (e.g., 1/4-inch) and gradually increase the size until you reach the desired diameter.
Secure the Metal Sheet:
Before drilling, ensure the metal sheet is securely clamped or held in a vice grip. This is crucial for stability and safety. Never hold the metal sheet with your hand while drilling. Use a minimum of two clamps to secure the workpiece firmly in place.
Drill the Hole:
Place the tip of the drill bit on the centre punch mark. Start drilling slowly and with caution. Drilling through metal generates heat and friction, so it is important to work slowly and apply moderate pressure. Use cutting fluid or multipurpose oil to reduce friction and heat buildup, especially when drilling through thicker steel or harder metals. Continue drilling until you have created a hole with the desired diameter.
Clean and Smooth the Edges:
Once the hole is drilled, use a grinder to clean and smooth the edges of the hole on both sides. Remove any sharp edges or burrs left behind by the drilling process. You can use a deburring tool or a twist bit slightly larger than the hole to smooth out the edges and remove any remaining metal fragments.
Remember to always wear proper safety gear, including eye protection and work gloves, when drilling through metal to protect yourself from sharp metal shards.

Make the pan water-tight
To make a metal condensation pan water-tight, you will need to solder or weld the corners of the pan. The method you choose depends on the gauge of the pan. For light-gauge pans, soldering is preferred, while welding works better on heavier-gauge pans.
To begin creating your pan, you will need to measure and cut your sheet metal. First, measure the bottom width and length of your air conditioning unit. Then, add three inches to both the width and length dimensions of the unit. Using a combination square, mark these dimensions on a four-by-four-foot piece of sheet metal. Next, use a shear to cut the sheet metal to the desired length and width. Cut all four sides to ensure the finished piece is square.
Now, you will need to create notches in the corners of the sheet metal. Measure and mark one inch from each corner, in both directions, using the awl and combination square. Cut out the one-inch squares from each corner with snips. Notching the corners will allow you to bend each side up and form the sides of the pan. Place the sheet metal into a brake, leaving one inch sticking out. Clamp it down and pull up on the arm to bend the protruding material up by 90 degrees. Repeat this process for the other three sides, resulting in a pan with one-inch-tall sides.
Finally, to make your condensation pan water-tight, weld or solder the corners together. Smooth the corners with a grinder and spray cold galvanizing onto each ground weld. To test for leaks, fill the pan with water. If leaks are detected, apply additional welding or soldering to the affected areas and test again.
