Thank you for the video...very informative.

Thanks for the video. I just got a new job with a tree company. I don't know much about the industry. I'm all over YouTube trying to learn as much as I can. I love how you care about quality. Just by the way you are concerned about the look of the wrap let's me know how much you care. Great video. BTW you can't see everything you are doing but you are telling us everything in such detail you don't need to see. And if you are confused about what he is doing because you can't see just call a pro before you get killed. Damn millennial!

How do you come up with your pricing for different jobs?Thanks in advance.

Darth Vader for a cable install, it costs me about 30.00 in supplies. If I can do it alone, around 285.00. More for longer cables

I think I'm finally seeing the difference between an Arborist and a Tree Surgeon. I believe a tree surgeon would come along and just remove the tree and charge more money. I'm a hippy at heart and firmly believe in the way trees help us day to day. Im educating my self in Arboriculture for sure! Thanks so much Blair

Very instructive. The cable tying especially. Thank you.

For me, this video contained many wisdoms - in taking the time to value one's own work, in appreciating the process, in looking deeply into things, in thinking things through thoroughly and in properly acknowledging the contribution of previous generations. If these kinds of values were more widespread in our workplaces, the world would be a fairer place..

Boy, you sure are "taking the time to smell the roses " when you notice the strands on the cable job in your tree go in the same or alternate directions. I would do them the same but I bet more cable wrap jobs get hit by lightning then noticed by non tree people. Just saying

1 year ago

People not noticing your cabling is a sign of success. If wrapping the cable in the same direction gives the cable a more uniform beautiful look then all the merrier. Cables are ugly things and they can't spare anything that makes them look even marginally better. Besides, I'm pretty sure the birds are closely inspecting the work and judging.

nice work Glenn

nice job! an old timer taught me a simple trick to get really clean wraps. after each individual complete turn, if you bend the strand up approximately 30 degrees, your next wrap will fit snug like it was done with a machine. a clean wrap makes the job look so much better, and prevents it from being pulled over the others. Blair, you use a simple clove hitch w/ a half hitch for your climb line? no taut line hitch?

1 year ago

Michigan Mister I use a taught line hitch. Don't use a Blake hitch but my guys do. I like a free sliding knot and in so comfortable with it, hey, I'm old school.

wow after reading some of the comments I'm litteraly laughing out loud. okay for one there's always going to be constructive criticism but this is the best cabling video on youtube so no need for that. second of all it is totally possible to cable a tree to high. in fact I'd be willing to say it's better to cable a little low say 1/2 the height from crotch to top, than 75-80% or 3/4... Especially when the tops are as small as the ones in the video it would be too small to but in a j-lag

Blair I'm not saying you did anything wrong. I'm just stating this incase someone was saying you cabled it wrong. Looks good to me where you cabled it

2 years ago

exactly right, you were the one pounding that puppy...

Thank you. Every tree decision is made based on what the Arborist believes is the best call.

2 years ago

The cable should be placed 2/3 the height above the split. I'm a certified arborist and I can tell you right now the higher you put the cable the better. It's not easy because it's farther apart but that will benefit the tree more.

cabling a tree has its pros & cons. Would you agree with me ? cut down the tree! Great video ,I learned from you ,Thanks

I always tried to install at points that I called "the shoulders" of the sections. I really enjoyed cabling.

Sometimes the smaller diameter wood up higher might not hold as well. It's only a lag. As he said, you have to see this tree.

1 year ago

Easy to say that without seeing the tree but I chose this location based on my understanding of the wood, the weight and the defect I'm trying to stabilize. I too am a Certified Arborist and this was my call.

2 years ago

I've never seen cables spliced like that, I learnt something today! In the marine industry, everything is pressure swaged.Thimbles don't just prevent chafing, they stop the wire being "crippled" by being pulled into too sharp a bend around the terminal point. Crippling a wire can weaken it by around 50% and cause fatigue loading on individual strands as the wire loads and unloads and the wire flexes at the terminal point.Not using a thimble also makes it hard to set a permanent tension on the cable, as the wire wants to keep straightening into a harder, tighter bend. The thimble prevents that and allows more accurate tensioning.

wouldn't best practice be to cut down the tree if its a danger to the owner and the public ?... I mean I realize no one wants to cut down a tree, but sticking these tie in is just postponing the job for someone down the road...

I'm no expert, just watched a slew of tree video's and if someone with your experience told me to chop it down, it'd been down yesterday..

If a cable is used to help make a weakness stronger, then it is a good thing. If the tree is ready to fail, then I advise accordingly. I have cabled trees before that should have been removed but get it in writing that the cables will not save the tree. They might help prevent a limb Fromm hitting a structure. So, cables are good and cables can be used wrong.

2 years ago

Great video! I'm used to the newer systems. Preformed wraps and lag bolts also Cobra systems. But there is still alot of wisdom and art in the "old school" ways. Keep climbing and stay safe!

I also use pre formed wraps but there is nothing wrong with the way it has been done for the last hundred years.

2 years ago

you ever try using preforms? that's what we use when putting in guy wires for powerlines we use the same cable. might be alot easier than hand tieing

Yes I have used them many times. This is more about "old School"--

Thank you for this great video. I'm having a tree trimmed and cabled tomorrow and I like to be informed on what is being done. I hope he displays the know how and pride in good work that you show in this video.

Welcome to the world of trees

Very nice! Exactly how I was taught, 40 years ago! I eventually switched to high tensile cable and diamond dust wraps for time purposes but I miss doing a nice NEAT cable wrap. Still use my bit and brace though! I really enjoy your videos.

I also use wraps but I enjoy the old way.

different than how I was taught, but nice to see another way thanks for the lesson.

Wonder, why not tuck the ends down and wrap the next course over them? Then only the seventh course would have an exposed end. Seems tidier.

3 years ago

There is tidy and there is getting the job done. You really can be too neat when you are in business trying to pay the bills

Good video. The placement height needs to be determined by the arborist on site. Also, steel is a good, reliable and inexpensive way to cable stout trees that don't sway too much, trees with good compartmentalization ability and trees with included bark.

You need to look at the tree before you tell me how the placement is wrong

4 years ago

Blair. You need to read the ANSI A300 (Part 3)-2013
34.3.2 Anchor(s) should be installed at or near a point two-thirds (2/3) of the length/height of the branch or leader to be supported, measured from the junction to be supported.

The A300 is the industry standard that all profesional arborist adhere to. This video should be pulled and replaced with one that shows the proper installation of a cable to industry standards.

4 years ago

You know, there are so many opinions about how to do something or why it is right or why it is wrong. I am of the opinion that the person doing the job makes the decisions based on what is observed. If I were to cable the tree as high as you say then the size of the limbs are way too small. All I am trying to do here is to minimise the movement in this defect. Steel cables have been used correctly for decades. They are also used wrong in many cases. Sorry Daniel, I won't "pull" this video.

5 years ago

some ideas might better be lost
like using static steel cable in trees

on splicing steel cable i agree, but not in trees

5 years ago

you seem like a nice guy Blair. Those cables are set way too low. That is not industry standard, and not recommended.. LEVERAGE... I put mine in as high as possible, often over 2/3 the height from branch union to tips.. Its actually nice to see the soft cable wrap.

And you should pull this video.. its that bad.. very unprofessional.. it would be like sending clients invoices typed on an electric typewriter.. or climbing on manila rope

tree care changed in the last 40 years, so did cableling
maybe take some time and update

maybe try light pruning, dynamic catch, little slack
good luck with it
