Step-by-Step: How to Flatten Out Humped Sheet Metal
Flattening humped metal is a careful process. It involves several key steps for successful restoration. We’ll guide you through each step to effectively manage your metal.
Assessing the Hump
Start by examining the humped area closely. Figure out how big and where the hump is. Knowing this early on is crucial for deciding the right repair steps.
Preparing the Metal
Before fixing it, make sure the metal is clean and clear. Take off any paint or coatings to reveal the bare metal. This step is key for a smooth fix.
Applying Heat
Heating the metal evenly is crucial. Use a torch to warm up the humped spot. This softens the metal for easier shaping. But, avoid too much heat to prevent extra warping.
Hammering Technique
With the metal heated, gently work out the hump using a hammer and dolly. Strike a balance in your approach. Too much force could lead to new issues. Good hammering skills are essential.
Finishing Touches
Once flat, let the metal cool down at its own pace. This helps it keep its new shape. Use a straightedge to check for evenness. Sand or file any rough areas to finish off.
