Hi All, Looking to Add a few more books to my collection! I am of course considering Shigo's modern arboriculture? 2008 addition? Also looking for something that goes into the biology of trees? Any suggestions/favourites? And if anyone has a copy of such a book I would be happy to grease your palm for it ! Sent using Arbtalk Mobile App

Hey TKO! I was looking at the petzl and the rock exotica. The twisted climbing system issue is the very reason I thought I'd give it a go! But as you I had completely overlooked the whole passing the rope over yourself issue Just mega annoying when lines are all twisted on my HC... What I tend to do at the mo is just throw my flip line round something sturdy, disconnect my main line and untangle it.. I think it must be something that bugs other climbers!?

Posted on 20th Apr 2013 @ 10:22 AM Do NOT use your Zigzag until further notice! Released by Petzl: Safety Alert Stop use Petzl ZIGZAG mechanical Prusik Sku. D22 This information is complementary to the Safety Information issued April 15, 2013 On Friday, April 12, Petzl was informed of an accidental fall in a training center in Germany. The injured person was moving at height using a Petzl ZIGZAG mechanical Prusik. The initial observations have shown that the fall was due to a failure of the rope end attachment hole. Our investigation and further testing lead us to conclude that this failure was the result of a particular configuration of a cantilevered and off axis loaded upper carabiner. Petzl test Results: 1/3 - Breaking strength of the ZIGZAG’s rope end attachment hole With this carabiner configuration, the breaking strength of the rope end attachment hole is greater than 15 kN. 2/3 - ZIGZAG with a cantilevered upper carabiner This is an incorrect configuration. Note: most of the carabiners tested this way pivot and correct themselves to be loaded on the major axis starting at 2 kN of force. Some carabiners pivoted and corrected themselves at 10 kN, without damaging the upper attachment hole. 3/3 - ZIGZAG with a cantilevered and off axis upper loaded upper carabiner This is an incorrect configuration. In this configuration, we have observed a failure of the rope end attachment hole of the ZIGZAG under 4 kN of charge (equivalent to short fall, repeated shock or sudden stop, etc). The cantilevered upper carabiner in this particular configuration multiplies the forces applied to the rope end attachment hole, leading to its failure. Petzl decisions: 1 - As a measure of precaution, we ask that you stop using your ZIGZAG mechanical Prusik. 2 - This stoppage will remains in place until we have approved and communicated an appropriate solution to maximize the safety of ZIGZAG users. 3 - We have decided to stop sales of ZIGZAG mechanical Prusiks. 4 - While there currently may be several solutions to maintain the upper carabiner correctly oriented on its major axis, Petzl cannot presently guarantee their effectiveness in all circumstances because we have not tested them sufficiently. 5 - Our teams are mobilized to quickly develop and verify a solution specifically for the ZIGZAG to maintain the upper carabiner oriented on its major axis. 6 - The availability of this solution will be communicated on http://www.petzl.com by May 22, 2013 at the latest. We are fully aware of the inconvenience caused by this issue. Please accept our apologies and know we take this issue very seriously. The safety of our users is Petzl’s first priority. Thank you for your continued trust. Here we go..... Sent using Arbtalk Mobile App

Honda hrh 536 qxe I run 2, the best mower in the market by miles. Downside- expensive! Heavy! Roller etc needs lots of looking after to avoid expensive failure Sent using Arbtalk Mobile App

Old man emu are fantastic for commercial use, if on a 110 combine with the ome had rear springs. Devon 4x4 are a very helpful bunch..... Be prepared to get the penny jar out though Sent using Arbtalk Mobile App

Haha and the pub! Sent using Arbtalk Mobile App

Haha why on earth does it need to be climbed!? Looks like there is nothing around it! Wish I could get 400 quid for trees we fall Sent using Arbtalk Mobile App

Why is it not for the faint hearted? I'm no forester! But looks like a very straight forward fell to me!? Sent using Arbtalk Mobile App

Do it everyday for a few years! Soon sorts ya out! Sent using Arbtalk Mobile App

Sound advice And your guaranteed a certain level of reliability with a new saw. Sent using Arbtalk Mobile App

Mine felt mega skinny, been running a HC on it for bout 6 months, and it has fluffed up like a gooden ! Sent using Arbtalk Mobile App

Can't watch that bloody program. I'm sure there are decent enough folk amount them. But I have yet to meet of hear of one Sent using Arbtalk Mobile App

What is the intended use of the saw? With that budget you will really struggle to find a non spicy! Stihl or husky. If its just for home use etc, get yourself on eBay and buy a McCulloch or something else cheap, will last long enough if ya look after it. Sent using Arbtalk Mobile App

I use carritool, love it. Hang the 260 or the 201t off it no worries. Sent using Arbtalk Mobile App
