As a Cable-Hauler Logging Contractor, I have a couple of tips; one has already been mentioned about how to attach ‘Bulldog’ clamps so you don’t compromise the strength of your cables, the second is that the tension on your cables increases exponentially the shorter the chord of your rope. The rule of thumb is to never have less than 10% deflection in your cable. You will have noticed when you swung on the cable as a test, the smaller tower flexed noticeably towards the other. Your 100kg weight could easily translate to over 1000kg tension in the cable! Imagine if you have 10 or 15 people standing on the bridge. There is more than enough strength in the cables, but the tower may need bracing.

I saw the tower sway slightly. You're right, the materials are strong and looks beefy, but the forces pulling the towers together when on the bridge would be multiplied to a lot of tension with 10 people that high up. May consider bracing, and maybe some bushings for the cables touching wood. Otherwise, the bridge looks great!

Hello Mr Moth, Once upon a time I used to rig scaffolding in NYC. cables are deceptive you won’t know they’re loose until it’s too late. Please heed my warning use at least three cable clamps in an alternating pattern per each connection plus a thimble on each bend. Your children are more valuable than the cost of these safety measures!

I agree to needing 3 cable clamps, but not to alternate directions. I was always told “you never saddle a dead horse” so the saddle sits on the side of the rope with the action, and the bare end is held in place with the U-bolt.

@JasonPeliwo

3/8” cable does require 3 clips. First one tight up against the thimble and the next 2 spaced approx 10x the diam of the cable away from the first (3 to 4”).

You did a beautiful job! I am jealous, Iver has the absolute best dad in the whole world!! 😊

Seriously Jason, this is an awesome project. Iver is going to have the coolest "tree" house around. He's one lucky kid. You're a great dad. You're a great grandson too and yes I know you probably jumped up and down on the bridge before letting Grandma up there. God know I would have done the same if not more. I don't know if you were a boy scout but you earned your eagle scout badge as far as I'm concerned.

Pretty cool Fort for your kid. As mentioned here before, those of us who work cables for a living see a few things that you might consider improving, lets call them “best practices”. Where you made your eyes on the ends of your cables, orientation of those cable clamps matter, use 3 clamps per eye on anything over 1/2” cable, space the clamps 6 rope diameters apart. And a thimble lining the eye wouldn’t hurt. That cable is plenty strong but the steeper the angle or “flatter” your cable the more lateral force you apply to your towers when you stand on it, consider running cable guy-wires to transfer that lateral force down to your footings if possible.

PRolong your cable life with adding thimbles at each of the loop ends. also never saddle a dead horse, in other words the cable clamp saddle goes on the load side of the cable with the u-bolt on the loose end.

Way to go Grandma! The bridge is pretty cool too 🌞

I have really enjoyed this excursion from carpentry to civil engineering. If nothing else I hope everyone watching has a better appreciation for how different (yet similar) the disciplines are.

Recommendation: You should put some bushings in any of the holes that bear a load of the raw cable. You can already see the holes at the top of the 4x4 posts are rubbing down and wearing from the friction and pressure of the cable. That will increase slop over time, you'll retighten them in a few months, adding more pressure, the same thing will happen again. So if you have 1/2" cable, get some steel pipe with a 1/2" ID and a wall thickness of like a 1/4", drill a hole to fit that in the post and epoxy them into the posts. Then run your cables through the inside of the bushing, you can even grease or oil the ID. That way, the cable is sitting on metal and the weight or tension of the entire bushing is bearing onto lets say an inch of wood, instead of half an inch and won't wear through.

Well... in really hard, daily playground-use. But I think he is building this for his son. There will be some time, there will be some use, but its not going to be used every day, by "a lot of kids", and not for a decade. His son is... 6 ? How long will he use it? Did you still used your local playground at the age of 11? I didnt. So there will be 5 years of use now and then, and a little play, a little wobble just makes it cooler.

Hey brother quick tip. Block out the railing posts. Same when building a deck. Over time the bolt hole can grow and loosen, but blocking is a rock solid backup and makes a crazy difference. Especially important with the load these posts will be incuring. Amazing job thus far!

@222dolson

Жыл бұрын

this is an awesome project but I was going to say this very thing. super simple to add in but you def need to do this. i believe it's in the deck building code attachment of normal PT railing posts to do this to ensure there is no deflection of the post when a 200lb point load at the top is applied at the top. normally keeps a full grown human from falling through a railing but in this case it's stopping the moment force from the handrail cables.

Your Grandma is awesome.

Your videos usually make me smile. But that grandma scene was priceless :-)

Amazing build , I love your channel.. All the comments about " Never saddle a dead horse " are 100% true so at the very least you should change them around and if you follow the rule of thumb math for cable clamps each eye you create for a 3/8" rope requires 3 clamps. After looking at the link for the cable clamps you purchased I've noticed that the saddles are smooth , not grooved to follow the stranded lay of the wire rope you've purchased. If your going through the trouble of taking them off I recommend changing them to a brand name like Crosby. Their product , although a lot more expensive is far superior and their manufacture specs only require 2 per termination for a 3/8" rope.

That ending was so damn sweet

The Zipline you add is going to be sweet.

SUPER IMPORTANT TIP ! When fitting the rope clicks, never put the “U” bolt over the “live” end of the rope, the cable that is going to the bridge) the unbolt goes on the “dead” end and the “saddle” goes on the “live” end (the cable that is going to the bridge). Otherwise they can slip and fail. 👍🏻👍🏻🇦🇺

You really should run all your eye bolts all the way to the eye as much as you can. The more the eye is cantilevered away from where it's anchored the more it can be levered on and loosen or bend and/or break. With as much as you have out, running them in will really tension it all up too but you may have to loosen what you've done already to get the extra distance.

@garyhead1561

Жыл бұрын

Everything is big enough for the weight itself but static loads are different than dynamic and if a large weight were to pull on the cable, the forces on it are different than just holding the weight and they're more susceptible to bending or wallowing out the hole from being wrenched on.

@JasonPeliwo

Жыл бұрын

If there was any chance of a lateral load on those (very long) eye bolts I’d say they should be snugged up to their shoulders into the 2x, but In this case the only lateral load they might see if if someone jumped up and hung on them from under the platform. Even still a grown man couldn’t bend them while under tension.

I was wondering about that as well. For the eyebolts that anchor the angled hand rail lines, (which create an upwards force,) I was thinking of putting blocking above the eyebolt to resist upwards torquing on the bolt.

@@JasonPeliwo Yes, I'm sure how this is set up it's fine. I'm talking in general also. Those particular ones have shoulders and are obviously meant to be run all the way up to it for the reasons I mentioned. Some don't have that and it's not as obvious so I pointed it out. He said he needed to do some tweaking and tightening too and that would be the first place to start imo. And regardless of if it will be fine and work in this application as it is or not, it's still good practice to do things the intended way and have even less to worry about. Why not make your weakest links as strong as possible if you can?

@garyhead1561

@@Nyall That's exactly why you run the eye bolt all the way to the shoulder. So it can't be torqued up as easily which keeps you from needing additional blocking. That's what the shoulder is there to help with. To strengthen the pivot point and give it a wider base to resist being torqued to the side which it relies on the shoulder being against something. If you don't have an eye bolt with a shoulder you should run a nut on all the way then drop a washer on it and cinch everything to that as close to the eye as it will go to create that same shoulder to prevent all the things I mentioned.

My only criticism would be to put the netting on the inside of the cables. It looks like you maybe attached it to the outside of the bridge... Which could work depending on how it's attached, but inside the cable would be a better failsafe. Awesome job!

She keeps looking at the camera like "Somebody help me, my grandson is doing experiments on me!" 😂😂

I would not tie the cables to the top of the worts but instead run them through the towers and then diagonally across to the ground with some buried concrete anchor. If you look at some big suspension bridges the part where the cables end is the biggest (by volume) part of the bridge.

Grandma Moth did a great job.

awesome!!!!!

That's awesome!!

Those "suspension triangles" surely need to be fastened all along the top cable, or all along the bottom cable, or both. Having them slide through carabiners makes them almost useless - standing in the middle of the bridge would just raise the boards either side of you, instead of transferring the load to the top cable.

I am really enjoying this series!

It's an old and valid method to test new ideas on the oldest member of the tribe. You found new mushrooms, you couldn't identify? Give it to gramps! If he's fine, it's probably good also for the rest. This method worked in the stone age, why not today?
