In this video I speak with the man who literally wrote the book(s) on backyard rollercoasters: Paul Gregg. Check out my sponsor Brilliant for a really fun way to learn! www.Brilliant....
I'm calling this a 'how to' video, but really it's deeper than that. This is a dive into what it takes to design a backyard rollercoaster. I took a lot of inspiration for the style of this video from Destin at Smarter Every Day. Let me know if you'd like to see more of this type of video on my channel!
Paul Gregg is a retired aerospace engineer who I spent the day with learning about his backyard rollercoasters. His rollercoasters are designed and tested to the same standards as airplanes, which is incredible considering the materials to build them are available at any hardware store. Paul has made backyard rollercoasters accessible to anyone with basic tools and a yard to work in.
Visit Paul Gregg's KZfaq channel here: / psg20101
You can find Paul's books and other information about building your own rollercoaster on his website: backyardroller...
This was a very ambitious video to film as it was the first on my channel that required significant travel expenses. It's thanks to viewers like you supporting me on Patreon that I'm able to continue making videos and strive to constantly improve them.

It's really tough to film a video like this with a regular camera. I'm not sure I have the skill to have done it without someone else there to film for me. The 360 camera gave me the ability to get the job done by myself. Maybe someday this channel will make enough money to hire an assistant and I won't have to mess with such things. I appreciate the feedback though! I may be able to tone down the 360 feel if I make another video like this by managing the footage differently.

Have you watched other 360 videoes? I remember theres one from a guy who wind suits, where he stuch the camera on his helmet with a stick. You can't see the stick in the video however because it is in the blind spot. You can see his helmet however, so it looks as if the camera's floating on top of his head. I know 360 cameras are basically 2 wide angle lens cameras back-to-back. So the stuffs at the top and bottom are the least clear and distorted.

@DmdMixZ 4 жыл бұрын

@@TiagoTiagoT a heartline roll is basically a barrelroll with such an offset, that the coaster isn't turning around your head but around your heart instead. That way the force is reduced. If the roll turns around the track axis, then the G-Forces in the Head area are incredibly high, on the other hand when the roll turns around the head axis then the force on the track will be incredibly high. The Heartline roll is kind of the happy medium and therefore making for a much more pleasant ride while still providing the same thrill

The loop would need to be significantly larger in radius also. That's why most coasters with loops go 40+mph and not 20-25mph. He could easily make a gravity coaster that had one but it would be a very short ride if all he had the room to do was drop to velocity to get through it.

Actually there are a few (modern) rollercoasters that have a (near) perfectly circular loop. However coasters with these loops tend to have a lot of “hangtime” by going very slowly through the top of the loop. That and having a large enough radius is how they keep the g-forces in check. One example of a rollercoaster with a (very) circular loop is Copperhead Strike at Carowinds.

Accelerating a birb through a radius has expanded my awareness of engineering.

@PaulGreggBYRC 4 жыл бұрын

To add a little more thought on the acceleration issue, these small coasters of mine have much smaller track dip radius of curvature than a professional roller coaster, so it's a concern for me if I have a taller person ride. But, professional roller coasters have much larger track radius of curvature in dips, so the effect is much less pronounced. I believe professionals design to what is called the "heartline" first, which is a 3D path your chest/head takes through space, then they design the track offset from that 3D spline.

I Just wanted to make a comment related to your Channel Name. One night, camping on the very top of a mountain in NE Wa, in a clearing where I could watch the stars, I got up around 4 AM as the sky was just showing light. A Night Hawk flew over to me and flew around me 7 times in a perfect circle probably 15 ft away from me, then flew off. I was amazed and spun myself around with the Hawk the whole time to keep my eyes on him. I must have looked pretty funny, lol! A few minutes later it came back and flew around me again 10 times then landed on top of my van on my XM antennae which looked like a mouse with about 6 inches of the wire showing like a tail, LOL. Amazing experience! It was beautiful! Another time while bleeding the brakes on a motorcycle, pumping the brake, squeaking drew in 3 hawks who perched above me on a tree branch. They actually made me nervous as I've seen them in action close up with a friend who rehabilitates injured or displaced birds, his were Cooper Hawks, he learned to use them for hunting. He said they were far better than a shotgun. Thanks for your work, inspired me to share when I saw your name.

Now I just need a house, and a wife willing to let me build a roller coaster. And a wife..

Please don't film with a fisheye lens anymore, I want to be able to see if something is straight or curved. Still a really great video though!

Gotta love it. A few sand bags one push and the track is then certified for a 150lb rider.

Great! As a mechanical engineer, I loved the technical talk. And Paul is inspiring... just ran across thisvideo, and now I want to make a coaster!

as a 6'6 guy I can attest that the head whip when riding coasters is insane when compared to my 5'3 wife. I always leave Six Flags with a sore neck and she just thinks I'm being a baby!

You ever think about how awesome it would be if the track started in, say, your kid's bedroom? You could have a window or a sliding door that would close securely around the track when you're not using it, but it would be the most awesome thing to hop onto the rollercoaster in your room and that ride right out of it.
