How to Build A Treehouse | 18 Wranglerstar

[@neuman1996]

there is nothing more fun for a kid then having your own tree house to play in, you are a great father Cody

[@Lochlann13]

I'm in my final year of school for civil engineering, and not once have they mentioned different grades of bolts. This is why experience is so much more important than book knowledge. I learn so much from your videos. Keep it up, Cody!

[@dinamboyz]

Its never over kill Cody when it comes to the safety of a family member, you've done the right thing. I'm always impressed with you. Keep up the good work my American friend.

[@travisprince1701]

These few videos that you just put up, are just what I needed after a LONG 2.5 hour football practice! Thanks for doing what you do Cody!

[@samgiesbrecht]

"Shade tree engineering" sounds like a video playlist I'd watch. Not having grown up around the trades, any engineering knowledge is useful. Great video, as always.

[@wulfclaw4921]

You have one of the most valuable channels on youtube. You get straight to the point and have excellent information ! Thank you for all your well explained instruction. You are very much appreciated. All the best to you and Mrs WrangleStar, Wulfy

[@mjallenuk]

You want your grandchildren to enjoy your hard work don't you? So upgrading and over doing every part of the build is completely and utterly warranted! Too many people don't bother and it always shows!

[@DigsDirtDigsMusic]

In the case of the bolts through the turnbuckle shackles and the link used to connect the chain and the eye-bolt on the stringer, the relevant specification is the shear strength as opposed to tensile strength. Tensile strength is important for the turnbuckle bolts and the eye-bolt through the tree. In any case, I don't think you have anything to worry about - you've constructed a very sturdy frame for this treehouse! Great progress and I am really enjoying the videos!

[@murfenator82]

Shear strength of a bolt is directly related to the tensile strength. For us in the aircraft business, you can use a factor of 60% to go from tensile strength to shear strength. A 160ksi ultimate tensile strength is approximately 95ksi ultimate shear strength.

I have always loved MORA knives... I actually have collected 3 generations from them. Their newer plastic and stainless ones, and old wood handled one from the 80's and an older one from the 70's. Absolutely love them. Their stainless knives are heat treated well and don't chip and come shaving sharp from the factory.

[@stout65]

I am really enjoying this series. I would love to start a project like this with my son. Thanks WS !!

[@socketman]

Thanks! I love little tidbits of info like the bolt grades. Had no idea, very useful.

[@jwolfe122]

Great video Cody. I wanted to say I'm an Industrial Rigging Instructor. And on your chains if it has an A OR 8 on the links it's meant for lifting overhead. If not then it is tie down chain. Thanks for the video. Jake W.

[@JakefromEE]

Anything worth building is worth over building! Very cool series, thank you Cody!

[@Vicmendo11]

Well Mr Wranglerstar, seems like you and I are in same mind set. I feel I could of been an engineer & architect. But the 3rd & 4th thing for me in preventing so would be the time & money. If it were me though, I probably would have capitalized on as much realestate as possible. Your awesome foundation to that tree house is a bit "over kill" for the small amount of realestate. Milling your own lumber would of pushed me to want to go completely around thoughs branches you've anchored up too. Still keeping the integrity of the tree it's self just building around it and using the rawness of the tree and it's branches on the inside of the house. The way it sit's at the moment is a 1 maybe if pushed 2 person deal for the inside of the house. Sorry, bigger family just pushes you to have to think bigger so everyone is included. Great build, awesome job, keep up the great work! Looking forward to seeing more videos in the near future. 👍😎

[@aarwim]

8.8 is the property class. You can quick calculate everything you need. Tensile strength: 8*100 (first number *100) = 800 [N/mm²] Creep limit: 8*8*10 (first*second number*10) = 640 [N/mm²] It is a great idea. Greetings from Germany

[@donnypatrick4487]

thanks for explaining the thing about the bolts. it seems like no one thinks to actually take the time to explain things like that. thanks again.

[@kaifischer7925]

Hello Wranglerstar, I´m one of your German viewers and I like your videos a lot (please excuse my english writing). But I´m a little confused about the bolt comparison. The first bolt you were showing for me (I´m trained mechanic) is a german standardized 8.8 bolt. (DIN ISO 4759) The standardization starts from 3.6 to 12.9 and 8.8 is a good grade to work with its used in many constructions. That means the tensile strength of that bolt is about 800 N/mm2 and the yield strength about 640N/mm2 (corresponds to ca. 116 030 psi in tensile strengh) Whenever you get such a bolt you can calculate for example : 8.8 = first number multiplied with 100 = tensile strengh=800N/mm2 (116 030psi) 8.8=first number multiplied with the second number multiplied with 10 = yield strength = 640N/mm2 (92 824psi) I hope that I could help you out a bit like you did in your videos to me sometimes :) Greetings from Germany

[@happycebu]

I always wondered what those markings were. Thank you Cody for that information.

[@Nix_sound]

I never knew about the difference in tensile strength of bolts or how to tell. This was most informative, thank you.

[@wranglerstar]

Luke Nicholls You are welcome Luke, Thank you for watching,

[@levifuller]

Thank you so much for the explanation of the bolt grades, that is something I have never know how to identify. The new EDC looks great.

[@ColtonBlumhagen]

Here I was about to go to bed, but NOPE! Wranglerstar! Haha awesome I love this series.

[@rcman124]

Beg my pardon. This was not a demand although in text (print) I guess it sure does look like it. If u could only see my emotion - excitement as I typed my comment.... I am like a kid I can't get enough of your channel an look so forward to the next video to pop up in the series. I could simply watch u build all day. Hence my " demand" for longer videos.....as a semi disabled man. And ex-builder, u have and are really inspiring and motivational to me. Sorry if my comment or I came across as rude... I was blessed with a fine wonderful mother and father. Who taught me all the same fine beliefs and values u possess... That is why I chose your channel. Go easy on us loyal true subs out here, who may not be so computer- Internet- text savy... God bless, Tony s

[@msd357]

8.8 is a metric grade stamp. Metric and sae bolts are graded differently. Metric 8.8 is equivalent to sae grade 5. Bolts stamped with a metric grade 10.9 are equivalent to sae grade 8.

[@jidana3194]

Thank you very much for your comment i was like 😳 since when the 8.8 metric bolt is grade 2 ? Again thank you don't get me wtong anybody can make mistakes and by the way i really like the knife

[@31415926rat]

I've had one of those knives for a while. I love it. I have a broken handle to an old axe that I was carving into a handle for mine. Mostly because I'm not a fan of plastic, but yah... great knives.

[@AsiAzzy]

About the bolt grades. The ones you took out are metric and similar to grade 5 in metric. It's 8.8, that means 800MPa tensile strength, and 80% of that is yield strength, (therefore the notation .. first number (8) is hundreds of MPa, and second number after the dot (8) is percentage where the yields strength is that is 80%) you can do a conversion from MegaPascals to psi if you like. a 10.9 would be similar to grade 8. I'd say the bolts were adequate for the job as they are grade 5 like, and they are usually bendable and less shatter-able as opposed to higher grades like 12.9 or even 10.9.

[@hypnolobster]

In response to the last thing you said, that whole "a grade 5 might be better because it'll bend but a grade 8 will just break because it's so hard" that everybody says is incorrect. A grade 5 bolt will bend AND break before a grade 8 bolt. Just a pet peeve, don't mind me.

[@AsiAzzy]

Kirby Weldon I was trying to talk about the resilience of the bolt. Under static load, yes: it's all about higher tensile strength. But under variable loads the resilience of the metal becomes extremely important. You wouldn't put there a tungsten drill bit even if it has triple the tensile strength, because it's not resilient! If you drop it it breaks and shatters! There are strong materials with low resilience (tungsten/wolfram), weak materials with low resilience (glass), weak materials with high resilience (rubber), or strong materials with high resilience (titanium). On a smaller scale same goes for steel bolts. Lower tensile strength generally means higher resilience, and those super-hard bolts are on the brittle side and could shatter if mishandled or exposed to bumps and shocks (they are not glass, but still fragile) Resilience in general is the property to absorb energy in elastic deformation. Some can't store much energy in elastic form so they "store" it in plastic form, but plastic deformations are not posible so there is cracking-fracturing from a well placed jolt of higher energy than the one supported. Also a bent bolt is an indication of overstress, while a fractured bolt is a failure.

[@kuhrd]

AsiAzzy Typically harder grades of bolts are case hardened and not thru-hardened so a grade 8 bolt that is case hardened is nearly as ductile as a grade 5 or a grade 2 bolt but the added outer hardness makes higher grades less prone to fail under sheer and tensile forces. You can test this by taking an equal sized bolt of each grade and bending them back and forth in a vise to destruction.

[@allensdiesel6501]

im glad to hear you guys got the book done!!

[@TheNytehunter]

Love that svord and the primer on bolts. Thank you so much for all you do

[@wranglerstar]

+Jerry O'Dell thanks Jerry

[@thedonqwet]

I just realized others had already pointed this out. love your work Cody. ☺

[@chops1911]

i'm with you Cody a little overkill usually doesn't hurt anything! Have a Blessed week!

[@tommyschauer3093]

You might heat treat the bolts in the buckle in your forge, to up the hardness. A good looking treehouse. Keep the great videos.

[@espenpedersen4787]

Great video series! Have in mind that mixing black/galvanised steel and aluminum could cause galvanic corrosion. Specialy outside, and with green wood thats wet. Same with black steel and stainless, mixing them is not good in the long run.

[@swart112]

No such thing as overkill when it comes to hids safety. Thanks for sharing.

[@wood0754]

Thanks for the quick lesson on bolt grades. Very helpful.

[@MrGojuyudansha]

Thank you again for another fine video.

[@etnordy]

What are your thoughts about taking bark off a tree (creating a wound) and the need for applying a pruning sealer to help protect it from rot/disease/bugs? I've always done it as a precaution without discussing it with anyone.

[@klemccasland72]

Thats gonna be the Worlds Strongest Tree House. Very Cool. Love the Vids.

[@Ryzomadman]

I learned something new thank you Cody I didn't know what the marks on the bolts mean't do now thank you tensile load I will remember that ...

[@RtCarolina]

Thanks for sharing your knowledge of bolt strength . Not many folks pay attention to such details, until it's too late. I have seen heads sheared off of bolts when decks collapse, not fun at all. I once had to stop a worker from salvaging 20 yr. old used 1/2" lag bolts from a demo project. He said, "What? They're perfect for a tree house or shed or something." I asked him how many he broke while removing them, he said, "about half"...

[@RtCarolina]

Try reusing them like that guy wanted to. Can you imagine how quickly they would have snapped? G.R.K. is the way to go. They have the best structurally rated fasteners.

[@mikeduffy8229]

I must say Cody you are doing a really nice job

[@thedonqwet]

the grade 2 bolt that you had is a metric class 8.8 blot. its tensile strength is just a bit more than the grade 5 bolt. but you are correct in saying that if it was a unc or Whitworth bolt without the lines, it would be grade 2. if a bolt has 8.8/10.9 etc, it is most likely metric. they also looked like 1/2" and 12mm. not 5/8". my 2 cents for what it's worth. ☺

[@WhiskeyRichard.]

Pardon my ignorance (and maybe this was answered elsewhere), but doesn't boring a hole as such through the center of the branch, or removing the bark like that compromise the health (and/or structural stability) of the tree?

[@lukecutcliff4360]

Finally. I love this show. Been waiting all weekend

[@johnkohler8600]

Another great video Codi Tree House is coming along great!!!

[@cabotbluegill]

Cody you may at some time want to explain that a grade 2 bolt is often used as a shear bolt and it can be very damaging and dangerous to replace a grade 2 with a stronger bolt and kind of study the application it is being used for. The way you are using the turn buckle grade 8s are fine but if you had 100 feet of cable one may want a bolt that would shear before the pressure was so high that the cable becomes a whip in effect

[@mikeduffy8229]

Mr Cody I forgot yesterday to say congratulations on finishing the book I can't Waite to bye a copy

[@jakejones5991]

Can't wait for the book to come out!

[@JorgeAraujo]

Your building a treehouse that will last as long as the pyramids....LOL! Great video as always.

[@riotdiscoman]

Not bad on your explanation on the bolt ratings, but keep in mind that your load on those bolts is "shear" and not "tensile" in the case of the turnbuckle. Without getting overly technical you may want to consider halving those load values in the case of shear. That is not exact, but will be a more close representation of the loads that those fasteners will support in shear. Great videos, keep up the good work.

[@live_free4thee141]

Sweet can't wait to start my sons tree house Thanks for all the organized info

[@dandeman94]

im diggin the shade tree explanation, learn something everyday.

[@karsonbranham3900]

That knife is pretty cool!! Thanks for the quick review. I think I will try one. Great video too!

[@Grant5272]

Great video as always. Looking forward to seeing this completed!!

[@xxbryan715xx]

Cody you change your mind about knives like most people change pants. You have gone from liking tactical folders to slip joints to neck knives to friction folders in the last few weeks.

[@kimballcody3328]

Love your videos. I didn't realize that there was a "support youtube'ers" option. It's a nice way of supporting quality channels like yours. I sent $10 your way. I hope you got it.

[@wranglerstar]

Kimball Cody Thank you Kimball,

[@kimballcody3328]

wranglerstar like they say at Chick-fil-a "it is my pleasure".

[@bignose880]

I'm not able to see the Support youtubers button. I wonder if its limited only to American viewers right now? I'd certainly throw 10 bucks your way.

[@kimballcody3328]

It randomly poped up while I was watching a few of his older videos. Maybe Cody could provide a link for it on his page.

[@HassanatuBissaka-vz6ki]

Thanks for all you do, keep it up

[@cowsofsuffolk2297]

Thanks for the bolt rating lesson!

[@SLlM4]

Something you might also want to mention is "Shearing Strength" on those bolts that are going horizontal from the direction of force. That thing has to have more shearing strength I believe in order to prevent breaking.

[@mattward4332]

Love this series. Do you think the eye bolt though the middle of the branch will kill it? I have not had very good luck putting bolts in trees and keeping them alive. Thanks as always for the Great videos!

[@memolei]

Are you planning to apply some kind of resin or protective coat on the places that you've removed the bark in order to protect the tree from rotting?

[@kavanschulz]

Hi Wranglerstar you should add the Victorinox Spartan to your EDC section of wranglermart. It's a great EDC knife/tool. Thanks Kavan

[@thenorthwestpreppers4457]

that is a nice garden you got out there! and what id give to have that store near by... wow....

[@matthewgarrison644]

Definetly going to look into that knife!

[@begininigflyfishing2430]

Your raising that boy right...your also a great dad.

[@horatio71]

Hi Cody, really like the treehouse, but was wondering whether drilling into the living tree is the best solution. I fear (maybe wrongly) that the bolts might damage the tree. Or are you sure that the tree will not have a problem with the few bolts? For instance: I've seen in Germany and Sweden hunters building a raised blind (not sure if this is the right word). It's a high seat for hunting either built as a stand alone raised structure or into a tree about 3-4meters high (approx. 10 to 15 feet) and are built to various degrees of comfort and sizes. The way they do it is not by drilling into a tree at all, but clamp the tree with big bolts in-between 2 beams - actually this is done twice so it looks like a "tick, tac, toe" cross with the tree in the centre. If this "cross" is done at a lower section and an upper section of the three (or trees), these can be combined to hold a hanging structure of a treehouse or "raised blind". Hope my explanation makes sense. Wonder whether this type of construction was considered or if there are arguments against it that I'm not aware. Anyone any thoughts? Cheers, John

[@cenelind]

I have always wondered about those hash marks. Thanks for the info.

[@jamesgcrawford]

See, I'm in the market for a new pocketknife, and that Svord looks nice, but I live up in Canada, so I was just wondering if they make a metric version of that three-inch blade?

[@Chimonger1]

Wow...are those a bunch of little holes girdling the branch between the bolt and the trunk [at about 4:13 and about 6:57 and about 7:12]? First bugs get under the bark, then peckers go after those by pecking thru the bark to eat them; then funguses get under there and rot the wood. Sure looked like it...how's that gonna work to support that corner of the treehouse for more than a few years, with the branch weakened by that process? [Information from our local arborist] IF it's not yet totally infected into the wood inside, there's stuff to put in those, to deter the bugs that cause peckers to peck the wood, and to prevent fungus from spreading to infect and weaken the tree...it'll prolong the life of the tree, but, that process still shortens the life of a tree.

[@colemcmillan4714]

Great video, really looking forward to the book.

[@derrickswordsable]

Thanks for all you do! Keep up the good work!

[@Boghog1]

not sure if it was mentioned elsewhere in the comments the 8.8 marking is actually an metric grade and about the same as a grade 5 having a proof load of 85,000 PSI and the 8.8 around 84,000

[@KyleEllis1989]

great video as always my buddy has one of those pesant knives with a wood handle its pretty cool and thanks for explaning the differnce in bolts and how to tell what it what

[@Gordonfan6]

In the video you say that those auger bits are easy to sharpen, could you do a video on how to sharpen them sometime?

[@s.m.sparks3485]

Wranglerstar! The treehouse master!

[@chrissmith7091]

Couldn't tell in the video when you drilled the hole in the limb, is the sap running in the maple tree now?

[@MIddlefish]

Love the videos Cody!! Also some shade tree advice from your new tree house is awesome! I'm not sure if you watch Treehouse Masters, but I do and this goes right along with them. I can't wait to see the finished product!!!!

[@JorisVanderPloeg]

Congrats on the finish of the book. looking out for it. greetz

[@Shannon_Lacey]

Thanks for the explanation on the bolts.

[@JohnJGato]

I thought 18 would never come Cody! ; ) But hey, super excited about the book, and I want to early purchase; how do I do that?

[@toddo62]

Just an FYI, when I try to add the Svord to my cart from Wranglermart I get a cart error. Love your work and videos.

[@ronniemcneese9805]

Cody, Since I'm from Texas and don't have much experience with big trees. What are all of those little holes from that we can see in the video? Woodpeckers maybe boars?

[@drum911]

defiantly going to pick up one of those knives!

[@rcman124]

Love the vids make these tree house ones Longer!

[@wranglerstar]

***** Not even a please? Just a demand in bold? Did your mother forget to teach you manners?

[@vwpolosbandit]

All those holes and bark removed, isn't there a chance of the tree getting an infection or bugs killing it? At home my father used to use some kind of paint whenever we cut a branch off a tree

[@anthonyflorence4389]

good work.my man teach us some more awesome stuff

[@meelas010]

thanks for that info about bolts. never knew it.

[@barrygirky8194]

Mr . Wranglerstar, when will your book be release? I how can I get a signed copy :)

[@leroycolombo2836]

Svord Knife looks great. Good for UK EDC due to the silly non locking knife laws

[@MegaGRGRGR]

Always learning something. Today it was bolts. I would have never known

[@abcarp1302]

I agree with AsiAzzy. You had a metric bolt. Standard bolts have the lines, metric have numbers. Did you hand burn when you held that bolt? haha Keep up the great videos.

[@Panzer1981vtr1000sp1]

Sorry to correct you but the metric 8.8 bolt is like a grade 5 bolt. And a grade 8 bolt is like an metric 10.9.

[@ChristiansWorkshop]

and grade 8 bolts like to sheer easier because they are harder and dont flex.

[@KuopioKallavesi]

BigDaBAMF69 Yes, 8,8 metric is standard that is used in vehicles and stuff, not in suspension/powertrain tho. however harder is not better always, it does not flex and can break.

[@slabadan2]

And more specifically the 8.8 mark means that the bolt has a tensile strength of 800 Nm/mm^2, and that the yield strength is 80% of that 800 Nm/mm^2 = 640 Nm/mm^2. I hope i used the right terms since english isn't my first language!

[@javiergonzalez1501]

a question, not to damage the tree by drilling through the center? thanks

[@thardman10]

from what i was told the higher the grade the more brittle the bolts are. meaning grade 8 bolts do not flex befor they snap as much as a lower grade would.

[@D.A_BIZ]

I need to be part of this . how do I connect to the builders please?

[@D.A_BIZ]

+Kenny I need to learn the work and catch some skills

[@renecerseda4415]

you are a good builder

[@MrZenerTech]

What about different grades of nuts to go with them bolts? Are they marked the same as the bolts?

[@yolandesellwood3196]

Thanks for the inspiration

[@RandallMoore1955]

Thanks for sharing.

[@dssk1023]

That knife is sweet!

[@ethancode5140]

Having aluminum and steel touching will cause faster corrosion of both. I think you should lose the aluminum washer.

[@jaredjregular1974]
