Backyard Roller Coaster - Our Brakes Broke The Cart!

Friction brakes need to absorb and redirect lots of energy. Check out this video to learn where not to redirect all that kinetic energy in a backyard roller coaster.

you could put the breaks on linear actuators and put optical sensors on the track to measure the speed of the cart and therefore change the severity of the breaking and disengage them once the cart has stopped then you could build a station with kicker wheels to move the cart around and to the base of the lift hill which could also be automatic so you only have to press the go button and the roller coaster does the rest.

My interests definitely do not lie in the details of mechanical "things", but I must admit this kept me watching the whole video. Good for you, Will Pemble.

You should try magnetic brakes. No friction means no wear!

I have a suggestion, it's not so much to do with the coaster itself but more the decorative side of things. if you plan to run this coaster at night one thing that would be really cool if you had an LED rope light all along the underside of the track.

Add a tunnel with smoke effect

Great catch on the brakes. Great coaster. I think you should go for another attempt at a heart line roll. You were so close with your last one. I'm not an engineer, but when I was watching the video, it appeared to turn the cart upside down with ease, but rather than the track looping around and back underneath the cart and rider while they were were weightless, it caught their full weight at the 8 o'clock position still beyond horizontal requiring the track to LIFT the cart and rider back to an upright position which wasn't good. If you created a roll with the path the person's head travels as your axis, I think you could come up with a winner. Think of it as a "Head Line Roll" where the head would follow the same path a ball would travel if tossed from point A to point B. It travels a straight line that has an upward catenary arc that only deviates on the Y plane, but not the X. You want the person's head to travel that arc and have the track spiral around it to turn them upside down and then catch them on the end without ever having to lift the weight of the person's body or cart back to an upright position. I get the impression that you're an engineer of some kind, so you could probably work all this out mathematically. Good luck. Every time I watch your videos you make your coaster better and better.

I got an idea you. Should put Christmas lights on the track

[@dawsonhollingsworth3535]

Get some proxy sensors to start and stop the lift when the car comes close to it

[@ddavies8517]

you should add LEDs on the track

Great work !

[@eyezat1]

I love your coaster and really appreciate the hard work and dedication you and the coaster team put into it. I know a lot of folks want to see inversions which would be exciting. I would just like to see all that extra kinetic energy in just extending it out, maybe another helix. Blunder on!

[@ZoniesCoasters]

Okay brakes aren't supposed to be THAT literal.

[@CommandoX798]

Maybe add a station platform, and a walkway up the lift hill for maintenance.

[@fyecoasters]

Great video!!

[@eastonbuttz3033]

Make a dual person cart or two carts to go at once 🎢

[@williamfairfaxmasonprescot9334]

OUTSTANDING JOB - use sandbag for testing

[@williamvannucci]

I never would have thought to do that! I probably would have completely scraped the entire brake system and cart, and start over!!!

[@ticklishhoneybee9754]

Uh, you know there's a reason that trains (cars, trucks, basically any wheeled vehicle) have their brakes on the wheels/wheel structures instead of the vehicle itself: so that vertical movement of the vehicle doesn't negate the brake's effectiveness. What you've essentially done here is move the braking forces from the bolt to... the bolt.

[@TheKennyJacksonMJ]

I think it would be safer if you made a fin under the car and create brakes with rubber where the fin slides trough it. Thats similar how most block brakes work on rollercoasters.

Man, i'm rewatching some of your vids, and im like "if i had to work for somebody, this guy would be so much fun to work for."
