I created the springs first using the dome tool.
I then modified these spring reliefs using the pill shaped vector and the dome tool.
Then I rendered the pieces the spring was too high and protruded from the box.
I would remedy this in the front view by nudging the spring downwards until it was within the box.
I also built a ‘bowl around the whole works. Everything would be merged to this bowl.
Four of these boxes would be routed for the log car trucks.
These will be routed along with all of the other pieces for the trucks and then assembled with the wheels done previously. Here’s a pic of the log car wheels, straight from the router.
