I've been trying to find out how this works as well, but I was wondering how the car would fully come to a stop since it is never going to hit up against something to make it come to a full stop?
The wingnut will compress the spring. The spring will eventually either be all the way compressed, or it will exert a significant enough force against the wingnut, both of which will stop the vehicle. Writing this now makes me realize that, if you're not careful, the spring may
be able to push your vehicle backward.
I would stay away from compressing springs and use the springs in tension
instead to avoid variability and increase reproducible with springs
That's what I mean though it will not come to a complete stop basically like ever, since it can by pushed back unless you have the exactly perfect spring which can be hard to find, so I wondering if there was a better way to use the spring but have a break that consistently stops the same way.
And I was wondering what you mean by using them in "tension" or so to say, since how does it get pulled rather then being pushed. Thusly, due to my confusion, I was wondering if anyone who did this before could give us some insight.
Moreover, what type of spring would you try to use then, since there could be many options open if you went for tension springs.
