Standing value of first and second thinnings
openspaceman replied to Dave177's topic in Forestry and Woodland management
Yes I doubt much motor manual first thinning gets done nowadays but back in the day it was never profitable unless you could get rail material out. Contracting rates were manipulated to make the returns to the landowner all look positive where in fact the better grades subsidized the poorer. I enjoyed the idea of upgrading the plantation but still cannot believe how stupid I was to take the work on, especially after seeing the later eclectic thinnings high grading by cutter select. -
Or the 70s on 3 strand nylon, 3 pulls up one down.

Daughter of one of my customers did her thesis on raptor DNA and using it to prosecute cases of birds eggs taken from the wild.

There seem to be a preponderance of we Andrews on this forum This is much as I was saying, not only is there less sugar in the sap in winter there is also less sap so whilst you want to dry the wood as quickly as possible you want to do it at a rate that the moisture is moving out of the wood to the surface, in summer this happens too fast in the absence of humidity control.

Tail of the cow, it's the way the stain looks sh*tty as it runs up the end grain, phrase was taught to me by the veneer buyer I used to fell for

The "queue de vache" in those pictures show why it's best to mill sycamore the day it is felled. The saying was "fell on Christmas day mill by boxing day. Brush off sawdust and initially stack boards vertically

I think the statute of limitations would mean they could only bill for 6 years

I've not been involved with any high speed tractors so don't know but most arb use comes under horticulture doesn't it? If so presumably this is in the agricultural and forestry exemption? Again with the exception of a trailer with unladen weight under 1020kg and powered brakes which needs no test. I am not a fan of overrun brakes where the gross weight of the trailer exceeds that of the tow vehicle so it's an interesting idea to me. Its only of academic interest to me now but when I was looking at the dutch 5th wheel trailers they had electric brakes and yes I would consider them to be powered.
-
It could of course be fitted with "coupled" brakes and still be under 1020kg unladen and hence not need plating, the unladen weight over 1020kg AND power braking is the special case. Of course anything over 3500kg cannot be used with overrun brakes, so it's anything with a MAM of greater than 3500kg needs plating. Big chippers on overrun brakes will be exempt as under 3500kg anything bigger tends to come under agricultural machine. I may be a little out of date having lost my job nearly 2 years ago but I still occasionally get calls from people at the old firm, one of which recently was about towing a trailer with overrun brakes behind a six wheeler, it only required an inspection for the trailer hitch and the extra train weight.

I had to look that up! It's apparently from latin for trunk, so over trunk??
-
Epi means over, as in epidermis being the layer over the dermis, so the epicentre is over the hypocentre of an earthquake. hypo meaning under as in hypodermic, under the skin

I think most firms charge about 30 quid for a consignment note, all hazardous waste requires one as part of the chain of custody, 5 batteries or less is allowed to use a shorter reporting method but consignment note still required. I only thought of two work arounds, first was to drive vehicle to waste disposal premises and change battery there, as it only becomes waste when changed, second claim the batteries came from litter picking on Network Rail land as they had an exemption to take hazardous waste directly from railway to a licensed premises.

Mine too but I think it refers to whether the cat's claws are out of its glove. I find it difficult to wear gloves for fiddly work but would advise those that get used to wearing them early on to continue to do so, apart from scratches and cuts they help protect skin from contamination as well as HAV.
-
Some while back we discussed 5th wheel outfits of 7000kg gross train weight, these have to have powered brakes and it seems unlikely they can come in under 1020kg thus they would require both annual test and an operator's licence. Which is why I stated over run trailers were exempt earlier in the thread as they cannot exceed a MAM of 3500kg
-
There is one type of trailer under 3.5 tonnes gross weight that needs an MOT that's if it is over 1020kg unladen AND has brakes operated via the vehicle service brake. As you say then it would also be subject to operator's licence.

I cannot remember but it was seconds rather than minutes

Back in 74 we tried steel line in place of a brush cutter blade ( before plastic line was available) and it fatigues and snaps in short order.
-
You would need to tune the length of string to the power band of the engine, make it a bit longer and it won't rev high enough. You can severely overheat a strimmer motor by dropping the revs with too high a load.
-
Power requirement goes up with the cube of the air thrashed about (roughly proportional to length of strimmer line) a large steel blade would sap less power and not send bits of plastic everywhere.

Timber/tractor winch
openspaceman replied to tractor dave's topic in Forestry and Woodland management
The power a winch can deliver is limited by the friction clutch, overload it and it slips, unlike the bad old days when the clutch of the tractor controlled the winch. The limit the winch could pull was then either the log moving or if it got stuck and one didn't declutch either 1 something broke 2 the tractor went backwards 3 the driver baled out as the tractor overturned (RIP John Lamb) or the tractor climbed the tree My Igland 4000/2 has a double sprocket, the smaller one results in faster line speed for highlead work but using your figures and a bare drum lifting a 4000kg weight gives:- Force=9.81 x 4000 Newtons Power-force x velocity= 9.81 x 4000 x 0.9=35316 Watts or about 47 horse power As the drum fills up the torque delivered by the clutch remains the same but the line pull falls and the speed increases. -
I've no idea but it looks like a polyurethane paint that cures with damp. What would worry me is the concrete has cracked because of settlement so something that just covers a crack is likely to fail when it moves again. Butyl liner will sort that. Have you considered cleaning it, painting on OPC and SBR neat then making a ferro-cement creed with chicken mesh?

Is there a blade available for a normal B&S type cut and collect push along that has more of a vacuum effect to better suck up lawn debris?
-
My understanding is the patent on the basic ingredient, glyphosate, ran out so in order to maintain market share monsanto got approval for slightly different product types which are thus still in patent.
