I have used cut off 50mm towball “balls” welded into the end of scaffolding poles at both end to act as gimbals in cast iron blocks so the scaffolding pole doesn’t fatigue ware it goes concrete and allows the branch to move more naturally wile still supporting it, I have also used 1” steel plate the ground anchor/weight spreader above roots just beneath ground and 30deg rosejoints in place of towball “balls”, but then I do come from an engineering background.

Go to a quarry ask if you can use there weighbridge for a small fee and borrow some stone to load uniformly to GVW, once you are loaded uniformly to GVW and have checked each axle weight get a permanent marker pen and mark around the shock-absorber on each wheel at the point on each shock ware the outer shroud passes over the body of the shock, once you have done that tip the stone and head home then paint a nice bright ring around each shock were the permanent marker pen line is, this will then clearly show the maximum compression of the suspension at GVW on flat ground when loaded uniformly

I just use a Coleman twin burner petrol stove, as I always have petrol about and it will cook/boil lots per tank full & it wont fall over like the silly gas cartage ones.

a 110 is 3500kg with HD coil springs & 3050kg standard coil springs. the 110 Heavy Duty & 130 use the same coil springs

when the tree height fits in exactly 3 hand spans at full extended arms length from the tree base/ground to the tip of the highest twig at the tree top the point you are standing at on level ground will be the same distance from you to the tree as the tree is high, for me the error in this method is <6" on a 100ft tree, so I always know exactly were to top of the tree will reach when felled. The same method can be used for cliffs, buildings etc, etc for working out height. It always seams to surprise people as the top most twig lands by my marker/range stick

Perhaps Ben has a long arm, a small hand span & a diff tape measure!

Why didn’t you just tell him he was wrong and didn’t know what he was on about & that unlike most people you have been trained/tested in the use of chainsaw with respect to aspects of H&S legislation and that even if he was the person on site responsible for H&S compliance his remit doesn’t extend to yourself as he probably has no training or knowledge in arboriculture practices or specific H&S regulation governing it witch is plainly obvious by his demands.

How many ground-worker have you got? & do you have enough Unimog’s etc, as there will be a lot of big stuff on the ground

see Part No. 295191 and image 11 in JOCKEYWH.PDF below http://217.199.167.226/Downloads/Trailerpdfs/JOCKEYWH.PDF http://217.199.167.226/trailer-home.htm http://217.199.167.226/index.htm

Well I finally dot a definitive answer from the TO in writing as to the status of the land with respect to the 1968 blanket TPO vs. the accurate map of the land. The 1968 blanket TPO is still in force however they are now in the process of revoking it (not my request) at some point in the next few months, so I am glad I didn’t do anything on there initial instruction by phone

I wander if the rotor head speed may be causing problems with a 10hz GPS units? As a rotor head speed will be approximately 600rpm witch is 10hz and multiples of blades will be multiples of ~10hz? Also as the rotor head RPM speed rises and falls as load/collective/throttle is applied the signal strobeing effect of the blades will move left and right of the GPS unit perhaps causing lateral drift and inaccuracy?

Yes it is all very interesting, you can see a lot that you wouldn’t see when on the ground or things you wouldn’t see when in the air Most of the time for parallel swathing its what’s built into the tractors I get to drive now and then, auto-steer is far more common on new tractors and its surprising how many farmer have RTK base stations for precision work at <5cm CEP for year on year repeatable work and how many others have sub <50cm CEP for basic non precision guidance or for light-bar’s guidance and spot rates, my self I normally use a laptop or PDA depending on what I need, most of the time its just area worked like acres per hour vs. fuel use or other things for costing, efficiency or proof or just finding a field! The logistics in remote places is normally transporting something some ware to a specific location well beyond were you would get a tractor & trailer or a site dumper etc &/or were there is distance to cover repeatedly I.e. you cannot operate site dumper on slopes steeper than 1:4 (~<14deg or <25%) (HSE regulation but ALWAYS less if manufacture states so!) tractor & trailers are limited by there total weight and lack of driven wheels leading to ground damage & lack of gradeability and the need of a much bigger space to turn witch often isn’t there, so with my Unimog I can carry up to 4000kg or about ~3500kg of stone and do less ground damage doing 3 journeys than tractor & trailer doing 1 journey or comparative site dumpers moving the same total amount over 3 journeys due to the much larger Unimog tyre size & capacity to run at much lower pressure for weight (lower ground pressure) It sounds like an interesting project for a helicopter though I doubt you need quite as high lateral precision as a farmer so a good quality L1 with SBAS or a beacon receiver would be good for ~2m CEP as windage would be more than a vehicle mounted sprayer but you would need 10hz PPS, also would it not be better for a pilot to have a light-bar-guide mounted in his forward FOV for swath in’s & out’s then a map just out of the FOV for glancing at other info/maping, I would have though that something like one of the Trimble basic agriGPS units with a light bar with a separate LCD touch screen VGA & hard mounted laptop & GPS auto shutoff unit, I think Derek at www.precise-solutions.co.uk is one of the few that deal in Trimble agriGPS in the UK.

bitween 3am and 4am hear it was at its peek

This also happens in piston engine air cooled aeroplanes but ALSO from hot! I.e. if you have your cowl flaps wide open then descend to fast on a cooler day you are at risk of cooling the cylinders down far to much causing a cold seizing of a hot engine.

>044 power in an ~024 sized/weight package (+ pipe weight!!!). yes more awkward on land dragging pipes but as soon as you get near water its useful because they are totally submersible, I used mine with diving gear on once in ~8ft of water

Use to have a hydraulic chainsaw for underwater jobs, could run it from a tractor or hydraulic power pack.

I have always thought it would be quite entertaining to fell a tree with a “light fifty” or deadwood with a BMG or crown reduce with a Minigun! (space permitting!)

It’s a long story, but basically I use to do commercial 3d outsourcing for computer games in my spare time mostly on stuff I had never seen before in the USA like buildings etc were I would have photos of the facades of the building but not necessarily the scale (implied from standard 2m doors etc) or the ground plan, so I use to use high resolution satellite images as a tool for working out the true scale + ground plan from them, then later I moved onto terrains so got involved in DEM’s (3d terrain maps), I have also been using GPS for years as well as digital mapping for my logistics work as is away from the public road in remote places etc, as well as the usual parallel swathing & area worked etc.

Hi, The tress that are coming down are the 2 beach trees shown in the photo, both way older than 40 years, the same is true of a alder & a sycamore. Of all the trees on the site >60% of them will be over 60 years and 10% are over 100 years or more, the blanket TPO stems from when the railway line was ripped up in 1968 witch was also when most of the houses were built that border it, so the original intention may have been to stop development. Still come next weekend the trees will be hitting the deck to the strains of some of my vocal “Christian church-going” neighbours chanting sermons from yonder embankments about TPO’s and how the TO will strike me down with a bolt of lightning etc, etc, etc, still it will provide amusement for the other 80% of my neighbours (who are non church-going coincidently)

A 1kg piece of wood at terminal velocity has more force over a smaller area when it hits you than a 1500kg car at 5mph dose!

The biggest disadvantage if quads is the unbraked trailers and or overrun couplings, off road vehicles should be running powered trailer brakes witch is something compact and full-size tractors offer. With vehicles with unbraked trailers regardless of size, hills will be the cause of most accident be it not having the adhesive force to slow/stop a load when travailing down hill or being dragged backwards down hill once traction is lost and in most cases its because the driver underestimates modest hills that are wetter than normal. Quad’s are normally 250kg to 300kg empty and with a rider ~375kg for the bigger ones, most of the trailers talked about are 500kg to 1000kg payload with no brakes and the trailers them selves weigh 100kg to 250kg. If you assume the standard coefficient of adhesion for wet grass of <30% that gives a 375kg quad with rider an adhesive force of 112.5kg. to climb a 45deg bank it would need 50% adhesion or 187.5kg of adhesive force just as a solo quad. to climb a 22.5deg bank it would 25% adhesion or 93.75kg of adhesive force just as a solo quad. for a 11.25deg bank it would 12.5% adhesion or 46.875kg of adhesive force just as a solo quad. if you take a 600kg balanced trailer and add the unbraked hill factor caused by gravity vs. angle that would be acting on the same quad above caused by a trailer you would get the following. a 45deg bank it would generate 300kg of trailer force + the KE factor from speed. a 22.5deg bank it would generate150kg of trailer force + the KE factor from speed. a 11.25deg bank it would generate 75kg of trailer force + the KE factor from speed. Or 375kg quad + 600kg gross trailer = 975kg = 121.875kg total adhesive force + the KE factor from speed required on an 11.25deg bank witch if that modest bank is wet grass with a coefficient of adhesion of <30% then you will be pushed/pulled down hill by lack of adhesive force generated by the quad (112.5kg) because of the much more important missing 180kg (<30%) of adhesive force that you would have got from a braked trailer.
