In this episode I continue to work on the various brackets used to support the grill and turn signal housings found on the desirable longhood models from 1969-1973. A small patch panel is also needed to bring the side of the fender and wheel arch down to meet the non-accordion style bumper that I intent to run. Not only do these modifications look better in my opinion, but they also reduce weight.
How to Create a Patch Panel Using a CNC Machine
Since the small patch panel is a convoluted shape I decided to make a hammerform using a CNC machine. Cardboard templates taken from the car were scanned into 2D images using a flatbed office scanner. Then I imported these curves into CAD software to create the desired 3D surface. From there the tooling paths for the CNC machine were created, and viola!
A simple nylon block of the right width ended up being the best tool to hammer the shape into a once flat piece of sheet metal. I’m really happy with the final shape and can’t wait to get it welded in place. If you have any questions or would like to see more please let know.
