Kudos! You young people are inspiring! Using math and engineering to make something fun! I really like that you did NOT have a lot of money invested in order to see your results and that you mentioned using mathematics as to help someone else. Thank you for sharing your fun! I would love to see the ride face forward especially as you get close to the end. Weeeeee!
At 0:36 and 2:10 the zipline trolley looks like the Naxen YSP004 zip line pulley tandem with ball bearings good up to 35 m/s (78mph) and able to handle 30kN (6,700 pounds). If so, it can handle ropes up to 13mm or a steel cable (rated up to 12mm) and carries the CE EN362 certification. At 2\:51 we can see the ladder going up to the backup secondary tree to double-anchor the zip line. What worries me most isn't the high speed but the two unprotected steel fence poles around the brake area (at 1:35) when the rider is swinging around randomly and get thrust forward (at 1:37) with lots of G-forces. And at 1:09 the riders should be careful not to get their body/legs over the pull twine that could break and cause the upper end of the twine to then wrap around the riders head or body - yikes! Still, I thought your proof of concept and low cost DIY was amazing - WTG and I can't wait to try something myself...
That is badass! I've been thinking about making one myself for my kids (and me!) in my back yard. The only issue is our backyard has a fairly steep hill and I know I can't make the drop of the zipline too steep. Hopefully I'll get it up and running in the next few weeks...
@@williamterry3177 no joke, I JUST walked outside and thought to myself; “I really need to get a zip line back here” 😱😱😱 What are the chances that you’d comment asking me this and I’d get an email notification as I walked outside thinking about it? 🤯
Dude! That is Rock Star status sh*t right there Man! Nice, love the Brake action! The best is "0f course, We're use'n bail'n string" .. Best use of a hay field and tree Ever! Thanks Austin! Peace
Awesome run! Love the tow rope and motor. I always wanted to put a tow line in the kids for skiing off my tractor and this gave me some ideas. As well as the zip line too for the summer ;). so thanks!!! Great video.
Great video, A tip that you may like. I did some zip-lining here in NJ and the guy who created the brake said he's actually got a patent out for the idea but I'm sure you can recreate it no problem. The idea is that instead of having that bungee cord. You'd use rope (strong rope that can handle the abuse) and rather than having it tied down, you'd attach weights at the end. Once you hit the break, the weights will rise up obviously and slow you down. You'd have to do some math to figure out how much weight to use. Maybe use a few bags of cement or something instead of a person zipping down to test it out. But that worked very well. Thanks again for the video. Be safe.
Seems like the weight would be heavily dependant on the rider? An 80 lb child slamming into a block attached to 500 lb of weights would likely not move the weights and be a sudden shock stop. Inversely, a 250 lb person hitting the block attached to 500 lb might move the weights quite a ways and not slow down fast enough. The bungee cord allows more flexibility for different sized riders.
@@jameswalker590 I wonder if they could devise some sort of air brake, like a big diameter pipe with a piston that is attached to the brake line. When the rider hits the block, she pulls the brake line and causes the piston to compress the air in the pipe, similar to a storm door. The rate of compression could be adjusted for riders of different weights with a twist valve, again similar to a storm door piston. They could rig multiple pipes like this too for redundancy, to their existing elastic cord brake. I agree with you that using a static set of weights for a brake would present some complications when there are big differences in rider weights.
I am trying to assemble something similar to this and have a motorized lift going but the same issue with the rope slipping, what type of foam did you use and where could I find it?
Cool. I've got a flying fox that has different stations, did you build the motor or buy it. Did you weld anything. Did you connect the wires. How do you even get electricity. Also what would happen if it suddenly rains it would ruin the machine.
I prefer backyards with slopes. So that I can start low and build up height. Since my trolley doesn’t need much slope for it to go. It goes like crazy once it starts moving. And better yet the slope isn’t even more than 5*. For it to start going fast.
Looking for your opinion... I have 150' of brand new 5/16" winch cable. I have two 26" strong Oaks to anchor to. I'm using 5/16" chain to wrap around the trees, do you think will chain be ok? I need to use the chain because my location is about 10' too long. I want it to be safe for 200 pounds. I've tried about a 70 lb tire and it works fine but haven't gone with a person yet.
@@brandib264 Oh yeah... I use it a lot now. I started by using a climbing harness and hooking myself (and others) to the pulley with that since its over a 35' deep ravine, but now I just use a strap and sit in it like a swing set. the zip line gets lots of use over the past few years! Here's a video on it, skip to 3:20 for start of zipline: ua-cam.com/video/aZMtkuFwJ5Q/v-deo.html
I think I used 5/16 or 3/8. I forget what I used but I used some of the largest. I used 7x19 galvanized aircraft cable. Either size will be strong enough. I bought a 500ft long spool on Ebay. It was like 200 bucks or so.
I have seen quite a few large oak branches drop as well. We were around the middle trunk and also had a fastening strap to the oak tree behind it. I believe it was plenty safe. Tree looked healthy all over too.
That doesnt look like cable. It looks like rope. No way its that torque tested especially after a long spell in the sun. I'd be careful if I was you. But I absolutely love your wheel thingy. I've yet to see that. Its just a guess but is the motor for that a motor for a haybale elevator ?? But did you hook it up to a battery or do you have electricity out there ?
I know it was a long time ago but i'm just now seeing this video How about instead of a hornest to keep one on it safely like how about some way of being able to stand up on a broad or something then you'd be able to control yourself better with maybe another pully one for legs and one for hands. Some thing for others to ponder on.
Don't like the suspension or the hard braking aspect... this homebuilt needs a lot of improvement!! there are better designed zip lines for home use on the net... check them out!!
Actually I’m building a 500’ zip right now and this video was part of my inspiration for doing it. From everything I’ve read and researched his is just about perfect. A little more slack in the wire rope might make the landing smoother but then it wouldn’t be as fast. I plan to get the longest turn buckle I can find so I can change the slack up for women and children but the men are going to be riding with it cranked up. 10’ of elevation per 100’ of cable is recommended from what I’ve seen. It’s going to be a little harder for me as I am about as flat as I can get on my 80 acres and there aren’t any trees. So I’m thinking a tower maybe since I would be able to use it for scoring motocross races on my track. Then again a lift system to a single guy wired pole could work too.
Looks can be deceiving. It was held in the tree with multiple clamps and the cable was rated for a working load of basically a car. Harness and all gear was official weight rated climbing gear. Pulley was also weight rated for humans. You don't cut corners at 50 feet in the air.
Best DYI Zip I have seen, That motorized lift is damn well ingenious
I figured that it was professionally made, the pulley system is a really good idea, thanks for sharing
Nice job 👍 I like the tow rope system you have and the brake is good too!

I dont know how much he spent but it wasnt a small penny that cable alone would be worth more then 400$ plus the bungy cable
@@TheTinkle1 Truth. We just got 250ft of the cable at home depot. That's a fortune!

this deserves an award
Justin Cleland Darwin will give eventually!
You seriously should have a back up brake system for when your current system fails
How could it possibly fail he has three heavy duty stretchers on both sides that are typically used for jumping off when bungy jumping
I feel like one of them t posts could come flying out of the ground
@@TheTinkle1 Accidents happen.
haha nice job!! I want to build one and this was the first video I found, I struck gold, thanks man!

This is the best zip line ever! Okay, when can I come by? I'll bring any fixings you desire! :)
Love it. What size cable did you use? And do you know how much tension you have on it?
We used a 5000 pound turnbuckle and pulled it up quite tight. We set the tension to how fast we wanted the rider to go.
Awesome man. That countryside looks familiar. What state are you in?

A pully i think
Love the motor puller. The brake is really good; what pulley are you using?
Pulley?
That's awesome mate!
I am definitely getting one
It could be better if u put something to hook you up with the moving line so you dont have to hold the rope , sorry for my english

I have seen Pine Trees Snap Very Easily and your 50 ft. Up Hanging from the Top, if this were an Oak Tree, would be much more Safe.

If you’re going to have fun, safety has to be third. Love this!
3:53 π r squared is for area of a circle
I said it wrong in the video for sure. We used math to determine the speed in which the rider would go up.
do you know how thick the steel wire is?
I forget but I could probably find out. It's 15,400 rated strength I believe. Snap strength was over 20k.
Niall Thomas think it was an inch thick

It definitely sounds like a cable. Where in the video did it look like rope??
Actually, Austin said this: "On ebay was the cheapest place. Buy strong cable. Mine has a snap rating of over 17000 pounds."
Adam Turnbull Torque tested? What does that even mean? Do you have any actual expertise or are you just yammering?
Let me help everyone out before they watch...There is absolutely NOTHING in the video about how to build a DIY zipline, NOTHING. Your welcome.
what is the motor you are using?
Its an old curtain motor. Its geared way down. Its like 1/2hp motor maybe.
I know it was a long time ago but i'm just now seeing this video How about instead of a hornest to keep one on it safely like how about some way of being able to stand up on a broad or something then you'd be able to control yourself better with maybe another pully one for legs and one for hands.

Can you tell me where you bought the cable?
On ebay was the cheapest place. Buy strong cable. Mine has a snap rating of over 17000 pounds.
5 years later and I'm wondering... did anyone get hurt on this crazy thing? love the simplicity, but the danger factor looks high!
Everyone survived with no injuries.
Looks like fun but the rider is coming in way too hot (pitch of and slack in the line is not right). Only a matter of time before someone gets hurt.
Awesome
Hope the bungee doesnt pull the post out, damn thing will go thru you
