This image shows how a pen has been attached to a spacer so that the pen can accurately follow the form of the master side of the clay model. It will mark a line on the foam core to be cut and then the template can be taken to the other side of the model to define exactly where the clay will need to go on the second side. The template has been positioned agains control points on the top and the bottom to assure accurate placement relative to the center line of the car.
This photo shows the foam core template being cut with an exacto knife. A wood template would be stronger and better but would take longer and cost more.
This photo shows the freshly cut template (a pattern from the master side) positioned accurately on the second side. It shows that a lot of clay will need to be added.
The soft clay (hot from the warming oven) has been pushed aside and smoothed by the template from the master side. This creates a vertical strip that is exactly the same dimensions as the master side.
