String Unraveling?

Post by GurtYo » December 10th, 2019, 12:40 pm

When I wrap the string around the axle, the string unravels before I can set it off. How can I fix this?

Are you setting the traps after you wind it? If so, are you letting the string unwrap slowly while you're holding the axle? Doing that will allow the flex of the rod to dissipate, which should help keep the string from unwinding. I also found that setting the car on the ground before you let go of the axle will allow you to keep more of the string wrapped around the axle. You could also allow the car to roll forward a bit while you're holding it to undo that little bit. As long as it remains in front of you, you don't roll it very far, and you're holding it, I see no reason that this would violate the rule about rolling the vehicle on the track. I'm assuming that you're wrapping your axle before you set the traps. If not, that helps keep the string tight.

Yeah, I am setting the traps after I wind it. So is there no way to get rid of this problem completely?

Assuming that I understood what you were saying, the only way to abolish it is to have a rod that won't bend at all. However, with practice and adjustments, it won't affect your runs.

I wouldn't say that's the only way to solve it. Last year, I had this issue, and it was really affecting our runs, so instead of starting our mousetraps with the built-in trigger, we made a lock on the axle that could be released with a pencil (this was legal under last year's rules - not sure if it still is this year).

That's a really good idea! I'll double check with the rules and try it out. Thank you to everyone who replied!

Curious about the lock on the axle? How was this done basically? I think it is okay from what I am reading in the rules.
