    Re choked running bowline or choked krab/SRT - There's a huge risk of the friction hitch sliding out of control on an SRT system or just jammin up making it impractical for the tie in technique lanctree's talking about. Shrek, adjustable friction saver - when you tighten it up on the stem it wont move when you take your weight off it as its a choked system so long as the rings on the saver are kept apart.

    You might want to try an adjustable friction saver? Allows you to move up and down the stem and is retrievable from any position in the tree. Does away with the dodgy crash and burn SRT element of the choked bowline/krab.

    Lancstree, The technique your talking about was first described by Mark Chisholm in the ISA Newsletter about 10 years ago. The article - http://www.treebuzz.com/pdf/tie-in.pdf .

    Yep, swabish hitch combo for flipline.....works a treat.

    Been running a Jonsered cs 2171 as mid size saw (70cc) for last couple years, currently cutting with an 18 bar very well, will run with a 20/24 no problem. The 2171 is basically a Husky 372xp in a red case. Compared with the newer Stihl 440s the Jonsered seems heavy and unrefined, but great workhorse. One of my first saws was a Jonsered 2055 turbo (ha ha), high revving no torque - was pathetic with an 18 inch bar, even with 15 bar it was a weird saw, sounded like a piglet with rabies. Still got it somewhere if any jonsered collectors want to buy it. Good luck with the saw, should be good for stubs other small branches when feeding the chipper.

    Very good point.

    Buzz, As Steve said, it was meant as constructive criticism. My main point was to highlight the fundamental design of both the Hobbs and GRCS (both products made by different companies, so there is no issue with infringing someone's patent if the basic design was to be copied), and comparing them with SNS's lowering device. You can see where the bollards are postioned on both the Hobbs and GRCS that they both use the tree to help distribute the load, meaning only one strap is required.

    If you'd made the plate bigger and positioned the bollard higher you'd only need 1 strap like the Hobbs/GRCS. It'd be even cheaper without the additional strap meaning you'd probably sell more units. The metal on your bollard looks very thin, you know that lowering device barrels wear out quicker when the metal is thinner? take to look at the thin metal of the ISC lowering device to realise how rubbish it is compared to the Buckingham Portawrap 3.

    SNS Trees, Look at the design of the Hobbs and GRCS, they have been designed to distribute most of the load against the tree in order to help keep the device in position during loading, note where the bollard is in relation to the plate and straps. You need to lift the bollard up on the plate in order to reduce the twisting load on the straps. Any comments?

    Whats the price gonna be Reg?
  14. scotspine1
    Nice pic Jon, this any good?
  15. scotspine1
    Excellent Reg, quality workmanship as usual. The twin bollard really does allow you to take massive pieces - at 5.00 in part 1. Why did the tree have to come down?
  16. scotspine1
    Yes Gary, what you want is a climbing helmet like this guy's wearing note the use of the flipline also
  17. scotspine1
    These?
  18. scotspine1
    Thanks for the replies. My main reasons for buying the Buckinghams is the twisted shank and the ability to connect the footplate add-ons, something you cant do with the Bashlin alloys I currently use. pics of Buckingham footplate -

    Anyone use these spikes or know anyone who does? are they any good?

    If a stub or peg helps your climbing, work positioning or rigging then leave it on. If you think its going to hinder your climbing, work positioning or rigging then remove it.
