Once you have the dimensions, use a metal cutting saw or chop saw to cut the steel tubing to the required lengths. Measure carefully and double-check your measurements before cutting. Remember to account for the thickness of the steel tubing when making your cuts.

Step 3⁚ Assemble the Frame⁚

Start by assembling the main frame using the cut steel tubing. You can use angle iron to reinforce the corners and provide added strength. Use a level to ensure that the frame is square and level. Use clamps to hold the components together while you weld.

Step 4⁚ Welding the Frame⁚

Once you’re satisfied with the alignment, use a welder to securely join the steel tubing. Make sure to weld the joints thoroughly, ensuring a strong and durable bond. Be careful not to overheat the metal, as this can weaken it. Allow the welds to cool completely before moving on to the next step.

Step 5⁚ Reinforce the Frame⁚

To further increase the strength and stability of the frame, you can add additional bracing. Use angle iron or steel plates to create diagonal supports and reinforce the corners. This will help to prevent the frame from flexing or warping under stress.

Step 6⁚ Prepare for the Panels⁚

Once the frame is complete, it’s time to prepare for the panels. Use steel plates to create mounting points for the panels. These plates should be securely welded to the frame and positioned according to your design. Make sure to leave enough clearance for the panels to be easily attached and removed.

With the frame securely assembled, you’re ready to move on to the next step⁚ adding the panels that will provide a smooth and stable surface for working on the car’s body.

Adding the Panels

The panels of your car body buck provide the smooth and stable surface necessary for working on the car’s body. These panels should be strong and durable, capable of withstanding the weight and pressure of the car’s body. Here’s how to add the panels to your frame⁚
