  1. From what I saw of the issue it appeared that some fairly minimal internal wear was the culprit. Not sure how cleaning would help that? Seems as though it's a fairly small, but significant design issue with the steel spring wearing on the aluminium body. 
    I don't believe that ever was the issue, as much as people claimed it was. I think it's a case of people jumping on the bandwagon, and blaming a piece of gear for their own lack of inspection and cleaning. Alot like people smashing the zigzag around branches and giving out it broke.
    If the manufacturers did testing and cycled the device to multiple times more than what you'll ever achieve climbing, and couldn't replicate it...
    I have no concerns. This is simply just my opinion. I am currently more than happy to climb on it.

  2. Six minutes in he talks about the multisling. I like it a lot, but I feel it's too skinny, and we shouldn't really be hanging on one carabiner. The skinny line is, as you will see in the video, hanging on two legs. But if the small ring got through the carabiner, it would change to loading dynamic to a single leg.
    The idea is to facilitate easy rope removal after some redirects, with no rope on rope friction. With the opportunity to advance the tip while in the tree.
    It's good, but I feel it could be better.
    I often use a sling and carabiner, sometimes with a pinto to get better angles. Just lanyard in, slacked system, attach sling via girth hitch and clip line in...
    Also you say we shouldn't be hanging off one carabiner.... But how do you attach your system to your bridge....

  3. We have a 220(I think) at work, it's a far nicer machine to use compared to a timber wolf. Much bigger hopper, variable infeed is very useful for larger/dead timber. We keep blades changed regularly, several sets in rotation so keeps it chipping well!
    Infeed is large enough to stuff the hopper with brambles/thorns/ivy and use a snow shovel to force it through

  4. While doing my NPTC climbing and cutting course I made it my mission to try as much of the instructors fancy kit [emoji23] including an ART rope guide.... Definitely a big reduction in friction using the rope guide vs a ring & ring cambium saver. Used both back to back on a drt VT & hitch climber set up.
    Never used a pulley saver so can't comment on that.

  5. He is pretty good to be fair. These stub axles had been identified as a weak point, so he had preempted them failing and sent me two new uprated ones. Even if I have to wait for parts to arrive it usually takes about a week to ten days so not bad really. 
     
    I've so far had to have rear cross member repaired, snapped the t-piece that holds the two sperate parts of the machinetogether and now sheared the stub axle. Believe it or not I actually have a fair deal of mechanical sympathy! I think I'm just on a run of bad luck, and as mentioned overloading the machine previously is now coming back to haunt me.
    We always say things break in 3s... So hopefully that's you done for a while [emoji23]
    Had nothing interesting myself bar fellas bringing me saws "there's something broken with this it won't cut at all, buy whatever parts it needs".... Unfortunately I can't replace the operator who repeatedly dulls the chain and can't figure out why cutting roots & muddy timber is having any effect [emoji2357]

  6. May i ask where you purchased the belts from and technique for putting them on as they don't have a release tensioner.
    Are you still using the negri chipper!
    I just googled the belt number, can't remember the number now but shoot me a pm if you can't find them. It was a gates belt. As for installed a bit of patience install over the crank pulley and partially over the drum pulley, rotate the crank pulley while levering over the over pulley.
    Actually sold it recently in the hopes of upgrading to a larger machine.
  7. Yesterday was dismantling two sycamores with a view! 200t and 461 with a 20" bar, what a combo [emoji108]
    Today is the first day of lockdown so added some much needed extra gear loops and a ring for the chainsaw lanyard on my harness, along with a gear check and saw maintenance. 1eb3e1f2c8449b5426c6a83da60e9d28.jpg4e51c7c59bb6b9d48addb324b940ac6e.jpg4e55b0d04846a533c25ee0ef24cdc1b7.jpg

  8. Probably re built it without fixing the problem that made it nip up in the first place . Don't do that again ! Check for an air leak from somewhere . Also don't use old fuel .

    My thoughts too, while spraying soapy water at the decompressor didn't product any bubbles I'm not convinced it was sealing up, as apparently the old was reused on the new cylinder, and the crush washer isn't replaceable on them so guessing that didn't seal up properly and produced an air leak.

    He's deciding whether it's worth while repairing or not... Might have a cheap 372 on my hands if I'm lucky [emoji1787]

     

  9. Just got an update
    He said "it's been a bitch to start hot and when it runs out of fuel since the rebuild"... He also said the rebuild wasn't expensive so I'm guessing crappy parts used and compression is too low
