| Actually... I don't even use a bungee lanyard let alone a manufactuared lanyard... My dad splices me up my lanyards from 3 strand hemp manilla. Hook a shit carabiner to each end one for the harness one to hook into the hook.

| something for you guys to think about when constructing your own chainsaw lanyard. You gotta incorporate a large heavy key-ring somewhere, just to make sure the saw will break away from the lanyard when for instance, it gets stuck in a cut when trying to cut a large limb. If you don't, chances are that you'll be pulled down along with a falling limb if the lanyard doesn't have a breaking device. A large and heavy key-ring should have a breaking strength of about 15 to 30 pounds. That'll hold the weight of the chainsaw real good under normal use, but when pulled down, it'll break and therefore is safer.Imagine that you construct a lanyard out of 8mm climbing line and 2 biners. That'll hold 500 kg's easily without a breaking ring somewhere. You may think that's not a problem, but do you think that your tie-in point will hold that kind of dynamic loading all the time? Don't rely on manufacturer's guidelines when they say that gear loops are breaking at a certain load. I know this because a few years back, we pulled apart a petzl harness. Petzl claimed the breaking strength of the gear loops was about 5 kg's, but after testing it has shown that they can easily hold 50 kg's wich is a lot more.One of them broke at 61 kg's.... The main reason for those specs is so you wouldn't use them for hauling heavy things, but stitches and used materials are usually much stronger than they claim they are. Also sometimes I clip in the lanyard on a d-ring for better access. Without a breaking device incorporated, that could result in a fatality. Last edited by quercus : 2nd February 2008 at 01:35 AM.

| The attachment point on the back of a 200T is designed so that it breaks. Dont know about the rating on gear loops on harnesses but I sure hope they go way over 5kg as many saws weight over that with fuel/oil/bar/chain and lanyard. There's also break away or tear away bungee lanyards now.

| I like the keyring incorporation onto the home made lanyards. When it comes down to it, the tear away lanyard is one more part of your PPE, but the best PPE is being taught proper technique and applying it - which is what I like to think I do pretty well. I will include a keyring of somesort after a few tests with other objects the same weight as my saw... One more precautionary won't hurt.

What will happen when a larger saw without such a ring is used? | |

| Find me 1 person yet who has been pulled out of a tree coz the saw got stuck? I haven't found one yet. And I have spoken with hundreds. Most saws will dislodge themselves or break somewhere. You are also supposed to have 2 attachment points when cutting, you are suggesting both break out. Yes you can argue but for me, I don't need one. I'll stick with the rigid set up and keep my saws aloft rather than watch them sail to the ground thanks.

| Q, sorry but I gotta agree with Ekka on this one. Besides, let me present a scenario. You're 60 feet off the ground, have your 361 on the lanyard, and while cutting it catches, kick's back! You lose your grasp and it flies out and around on the lanyard (yes, highly unlikely...) A moment latter it is dangling under your feet (since your lanyard, of course, wouldn't have it dangling at knee-level). Replay with Key Ring involved... saw catches, kicks back, flies around!!! Ring snaps! Saw goes flying 60 ft crashing to the ground, obliterating itself into litte liny pieces. You consider super glue! Then you wise up and yell @#$%^&*!!!!!

| I bet a lot of good saws have been lost to premmie tear aways. What's a 66 fully fueled, oiled etc weight, dump that and you have 7kg falling 6', total impact force on lanyard/saddle would be? How about them Ace boys and McMahon, 120 Huskies up there. I have in the past on critical dodgey cuts unclipped it from my saddle just in case, that's always an option too you know.

| Do you really need a 066 upin a tree? Your alot stronger then me. The most unsafe I've felt in a tree is always with big saw. . An 044 is ok with me. |

| Depends on the tree but I have in the past for eucs, the size and hardness of the tree determines it, like ironbark. I dont think there's even an ANSI standard on enforcing tear away lanyards. Nor have I lost a saw out of a tree.
