Small complex panels
This tutorial is designed to explain a process of making small complex parts that need to fit accurately around chassis & engine components.
A buck was not a practical option so i did a little free style, shape a little then test fit, shape some more. I did cut out some tag board and tape it together to get a visual and to cut out blanks. IMG_0544.jpg IMG_0548.jpg tight clearance between the frame and turbos required some creative work to get a nice looking part that blends with the rest of the project IMG_0568.jpg simple bends at the bottom, but a wave and a radius at the top. the flange will be welded on to the side panel for the engine compartment. IMG_0570.jpg Now that looks about right, now i need to make a mirror copy that is the same shape. IMG_0529.jpg IMG_0541.jpg tight..... just room for my first knuckle

The flexible shape pattern was used to get panel size and placement of stretching. the pattern was cut accurately so it could be used to layout the flange and the cut line for the weld.
IMG_0575.jpg IMG_0577.jpg pattern shows stretch, I transfered that to the blank IMG_0578.jpg IMG_0579.jpg IMG_0580.jpg linear stretch dies were used in the power hammer, could have been done by blocking, and wheeling or with a planishing hammer. IMG_0581.jpg IMG_0582.jpg IMG_0583.jpg

Lovely work with sweet contours.
Makes me smile to see it all coming together with such a nice flow. (nice patina on your work surface )

thanks guys.
a couple more pictures of the tight clearance, and frame trimming required to achieve the final clearance. At the beginning there was only a 1/4 " space. Lots of head scratching, customer wants the turbos and engine to be the focal point, so not many choices of where to put the turbos. IMG_0542.jpg IMG_0557.jpg

Tipping the flange
The flexible shape pattern works better on a panel with more shape, so I roughed in the stretch areas and was careful not to overstretch, my guess was that it needed more but I could add more later. I chose a flange width of an inch because it needs to be welded to another panel and I wanted some room to finish off the weld zone later. The tall flange made shrinking the front corner more difficult, but still possible.
rolling a crease into the panel with my powered pexto the lower is a firm nylon. IMG_0584.jpg Attachment 36233 IMG_0587.jpg IMG_0588.jpg IMG_0589.jpg IMG_0590.jpg IMG_0592.jpg more shrinking & tipping to get 90* IMG_0596.jpg IMG_0597.jpg match the backup tool to the curve and the sharpness of the crease.
