very similar predicament then! ive got the rc2000, 2 x 19mm slings and a 150kn block what is wrong with my maths: the highest strain is in the top pulley and sling so you choose your rigging line relative to their failure yes? sling MBS rating => 9409kg = 90kn so safe load then is 9kn on textile block - 150kn => safe load 30kn on metal so the block is far stronger....the sling is the limiter rope experiences half the load of anchor point so you can put no more than 4.5kn on your line. fine - 450kg back to the failure - the rope has to fail before top sling (so well below half the slings MBS) so it should fail at no more 40kn even a 12mm lowering line has a MBS of 40kN! should i get the bails string out!???!?
-
yep 14mm rope is easily made the weakest element in the system then but then it reduces your capabilities......go for the 16 and all your redirect pulleys & strops need to be up for the loads = much more expense. there are some nice and pretty reasonably priced small pulleys out there if you can keep the loads small.......
-
Thanks Aaron - big help. first proper lowering rope to complete the kit with rc2000 i have been building up. got no stockists near me so buying blind online. I am wondering how it compares to the XTC12 (which has a lower MBS) for snatching....anyone know if the absorbancy and wear in general use are better ?

Afternoon All, just ordering some bits from Jonesie and i am looking at 16mm marlow bull rope - is it suitable for natural crotching, pulley rigging or fine for both? I'm after a rope that doesent mind a bit of rubbing on the odd branch Cheers chaps/chapettes Mark

oops i quoted you! thanks for the advice i got a bottle somewhere. i think 240 is fine - i have higher but every blemish tends to howl out and dings show up more plus my fingers hate sanding more than sawing! Was going to do the seat today but got too busy in the end Cheers:thumbup:

is this the all the friends youve made on mumsnet?

Hi All, Just finishing up last stages of a macrocarpa "throne" i have carved. Pics coming soon. Whats the best finish for the above - i prefer oil/wax but if it has to be varnish, it has to be. Currently sanded to 240g - should i take it to 400g? Two small bore holes already in one corner. Thoughts please maestros Cheers:thumbup1: Mark

Hi Steve,
Yea i got mine too - and i'm not sure....the cover letter said i had failed but i read on and it said i passed on the lantra forms!!!! Need to speak to Lynher about that one! I'm going to have to wait till Monday.
Bad luck matey - where does this leave your plans to become a tree inspector?!?!? If you take it again make sure you read londsdale and mattheck till it makes you sick - i guess you can just do the assessment again

urgent help with hedges in a conservation area
arbmark replied to yourm9's topic in Trees and the Law
sort of on the point - i heard you could coppice hedges of overgrown trees, which meant you could then remove them a couple of years later once they had grown back into hedges. whaddya all think about that one! havent tried it!!! and probably wont either... -
he sure is never reduced a deodar but i have kept 'pruned' a medium sized atlantica and it looks pretty good but then it is more 'interesting' species in terms of colour and form. That looks great Tony i would still give the crown lift/ open scaffold a good go -and whats the view of - a road?! surely a view through an open canopy of sexy branches would look much better. sometimes its just the instant fix that the customer wants that the problem removal would be such a waste - get it TPO'd now!
-
agree tony but could you make it look as lovely??!!!!
-
naah......gradual crown lift, thin, retain leader and aim for the flat topped specimen it would happily reach anyway - could be several years repeat work on that one! its not a pine. what is it? cedrus? actually it could be cypressy.......hmmm i wonder who'll be along to set me straight.....
-
whats the question - does it burn?! i would expect it to burn lovely, with the old reservations about resin in chimneys.........
-
chains a little dry guys but this saw has always had oiler issues and and to go back early on (Stanton Hope were excellent). But never been happy with it but you have to muddle on. Will go back and see if its totally dry.....Yep it is now - it had flung a little bit before. I thought that if the oil wasnt getting through the chain tightened slowly but i may be wrong cheers guys will check the pump tomorrow in the daylight
-
whats going on?!?!?! picked up the saw (after giving it a cleanup the other day) and after a couple of cuts the chain went all tight. i slackened it off a bit, it tightened itself up again. Played with it for half an hour and cant get the chain anywhere near the right tension - when i set right it then tightens itself. gremlins? some sort of fail-safe? half expected jeremy beadle to pop out out of the bushes. any thoughts guys? ta very much.

doesnt always work man but worth a go. youre gonna get epi'z all over the place i expect anyway - just keep the ones you want and snip out the ones that are going blatantly wrong (or cut back as spurs) - theres a balance though with letting the tree get its xylem function going well again, so tell you mate to be patient and it'll need several visits and cupcakes/babyshamz to boot
-
did you remove the prunus then? what about making some bark nicks to encourage a bit of epicormic action from where you want it.....if its now got light it could help to even up the crown?

Yea -"alder scarce at all" what a load of rubbish! Felix whenever i see your name youre always being a naughty boy. Moderators! Moderators!

Ecological woodland management
arbmark replied to Charlieh's topic in Forestry and Woodland management
liking this thread very much, and i'm off to the course on WIG on exmoor. Nice one Charlieh. Cheers mr Mark -
i have a mate (former arb) who does this for a living freelance and is a bit of a pro when it comes to hoisting fat camermen into the canopy - pm me if you want his details - he's in bristol. Suppost this is your job though! He's a helpful kinda chap but its his livelihood if you know what i'm saying!!!!
-
he's processing which is a different use class from forestry, believe it or not, hence the need to apply for business use....now windfall has admitted retailing logs they will want him to apply for it i expect...its good to keep things legit and the planners are usually helpful when you go to them, at least on the face of it.

if you want a towable and the timberwolf is too much try a bearcat....parts are a bit tricky but simple and well built. a new one is under 5k i believe from abbey pro
