Standing value of first and second thinnings
openspaceman replied to Dave177's topic in Forestry and Woodland management
I doubt we ever got up to that, mind we were in scots pine mostly and the trees were 0.05m3 so if you didn't have a good assortment of PSR material paid by the piece and just cut pulp the pay was poorer. PSR made the forwarding a challenge. Prior to that I pulled tree lengths out as it seemed to result in a better selection and I'd be making 50 trips a day over an average 500 metre distance. Last week I visited the lad who was working for the opposition respacing natural regen from the period when I'd moved on to hardwood, about 83 I'd guess, he was very prolific with a saw. Now he owns and drives a timberjack forwarder with intelligent boom control, self levelling and rotating cab and shifts 150 tonne a day (mind its 5metre douglas sawlogs off a clearfell). We've come a long way but I doubt we'll produce crops like this with the current establishment and thinning regime. -
I'd like to see the workings for that

I was wary of suggesting rope in this case because of the need to to and fro the piston, increasing the risk of a bit of rope working its way into a port. I normally use rope and have never owned a piston stop.

Be aware if the clutch is binding on the drum it won't pull apart when you take the four screws out. Try locking the cylinder and then carefully joggling the blade back and fore to free it off prior to dismantling.

Rusty clutch?

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.
