The rule of thumb for the pellet mill was the biggest particle shouldn't exceed 0.4 of the finished pellet diameter ( 11, 8 and 6mm pellets) so yes there is a big comminution cost if you don't start with sawdust. My old boss had a 50mm puck machine ( reciprocating rather than rolling) and that made some lovely briquettes from sawdust, he sold it before I could play with it as the electricity costs frightened him.

You don't need an operator's licence if the unladen weight of the trailer is under an old ton (+-). It's the plated weight of the trailer that counts for the combination weight, e.g. he cannot legally tow a trailer plated for 3.5 tonnes even if it is empty. Only dedicated trafic officers tend to know this. The 50km rule is only for workers carrying their own tools, not delivery drivers but again hard to prove.

IIRC we were getting that in 1978, bars were £19/tonne, it all went downhill after that.

It's just heavy gauge polythene I think, so not breathable, Tyvek roofing felt is the breathable stuff, great for roofs but pointless in a barn. A firm I used to work for trialled a fleece over their chip heaps, to get the mc below 45% for the power stationm but there were problems, I wasn't involved but the use was abandoned.

Dunn at Shredco but Southampton is out of economic transport for Slough Estates, a colleague is having a problem getting rid of arisings around Poole.

That's my view, the breathable stuff is for confined spaces which the vapour has to get out of or for covering heaps where the vapour would otherwise condense back on the top. Even then there are issues with getting it on and off the heap. I cannot see any advantage over a tented structure, like a polytunnel. Apart from when it's raining the RH is always below 100% so some ( even if insignificant in winter) drying will occur if the wood doesn't get re wetted.

I do but I was last there in Feb 2007 and it's all changed since then, especially since the firm I snagged installations for went bust.

I thought grey wagtail

Yes and it probably also includes wood based materials like pulp for cardboard and paper. This is why recycling had such a big impact on the lower grades harevsted, if you recycle 15% of imported timber products you wipe out homegrown pulp demand. This and having the import tariff removed with GATT was the deathknell of homegrown virgin pulp use in UK, Exports and firewood may have taken up the slack but at much lower prices in real terms.

It's a long shot but if there's a good %age of solid wood in it it may be worth seeing if the current IKEA facilities manager is as accommodating as before. I worked on the boilers there 5 years ago and we ran some arb chip through them. AJH

It is a subsidy dictated by the government but the mechanism that pays it to renewable generators is a tariff put on all fossil generated electric and then paid out by the electricity companies, most recently as feed in tariffs. So consumers of fossil electricity directly pay for the cost of renewable electricity ( 2-4 times the wholesale value) As I sit here UK is probably consuming 55GW of electricty and several times that as direct heating, 1 tonne of dry wood contains ~5MWhr of heat and we grow how much harvestable wood? Don't get me wrong, I've been involved with wood harvesting and wood burning for many years but...

That's a tariff of 31 and a tree with a dbh of 43 should have 1.38m3 overbark

Me too but in my case its the pink bamboo and shrimp net from my granddaughter's seaside trip.

I'd use a grapple loader but in the absence of that what about scaffold poles made into an H frame, straddling the trailer wheels. Two close spaced poles under the front trailer wheel for the first bag and roll forward for the next. Bags hanging like a garden swing and then haul the top bar over to load. Like raising the side of a barn in a western movie, or indeed how a skip lorry operates. As a typical builder's bag has about 0.7m3 and 300kg wet I suppose a 1m3 bag would be 500kg worst case. Given a few dimensions and top stacking height a bit of trigonometry would give the maximum pull required.. Otherwise how about a simple gantry crane but consider loler

I've worn hat, muffs and visor since 1974, in fact since I traded up from Danarm DDA110 and I didn't use that much. Tinnitus is the bain of my life and just reading this thread makes it more prominent. I've more than a sneaking feeling that chainsaw ear defenders aren't much cop for the lower noise from chippers, tractors and such but too late now, damage is done.

Whilst looking for these pictures I came across the one of him posing next to the pine that was struck by lightning whilst he was snedding its neighbour, he'd not work in the rain after that. We reckon it was the induced current in the saw handle that knocked him down, otherwise unhurt. Incidentally I went and retrieved my 1164 and grapple loader today, about 6 months ago some scrote smashed the screen and nicked the main lift ram off the FMV290 so I need a replacement and they don't seem to be readily available.

I'm no arborist, mine is a forestry background but if you consider the environment in which most gums have evolved it is subject to flash fires. It puts up a long initial shoot in order to keep its growing point out of danger but may not succeed first time, so it self coppices after the fire and second time it has a sturdier root system. In SE UK environment it seems to outgrow its root system which is why many gums develop a bow at the base. IMO it actually pays to coppice it at 3 years and then store a single stem.

Don't know about conifer but small hardwood enough to knock the flashing beacon off a transit cab :-) These later ones combine the engine cooling flow with the chipper disc flow. Never seen a timberwolf nor looked at the greenmech fans.

I'll describe our system just to illustrate problems, we use 500GB on 2 cameras 1 DVR and that lasts about a month, the compression is high so that whilst the cameras give a decent image in real time the playback wouldn't pass the driving test for eyesight. To my mind the biggest problem is isolating the incident when reviewing by playback so I think one of those pir wildlife cans would be a handy adjunct, I do use one on the site. I also think hot swappable disks would be handy. Most seem to feature a " record on movement" function but I cannot get that to work. It seems to be done by software analysing the screen. Playing back a day's recording at 8 speed is still 3 hours and you'll miss something. This sytem, of unknown make supplied used by our computer guy, has next to no functionality in remote playback. Do not use cameras with built in infra red leds, the back glare from spiders' web makes night views impossible, arrange a separate light source. I've just reviewed the bandwidth for remote viewing, and bearing in mind it only uploads about 1 frame from each camera in 10 secs, so you cam miss a lot even though it is recorded at base, in 47mins it has used 50MB. The big advantage is seeing a machine is where it was parked and a door is still intact.

I suffered the same recently. Similar two puncture wounds, bruising and a blister. I had a google and decided on a spider bite but would be interested if you find out more. I know there is a colony of venomous american spiders in Bucks but I wasn't near there. I have a photo on my works camera.

Here's one from around '82 I guess because we used trousers with kevlar inserts just about as soon as I heard of them and Tony is in jeans. countydual | Flickr - Photo Sharing! and this is from summer 88 after the storm 4510 | Flickr - Photo Sharing! I think I got the cranab in '84

Yup found some but in an old album, I'll have to scan the page and then crop them. Mind I don't know how to post them.

Not on a mog but had dual 12x38s on the 1124, made the thing 10.5ft wide!. I don't think it increased traction noticeably skidding but spread the load a bit. I did have some sidewall issues with picking up stones. This was with the original county cones rather than quick fits. The main advantage was on the steep bank I was working. In the end I just fitted 14x34 as the singlke 12x38 wouldn't cope with the cranab 4510 when I bought it.

Pallet wood is normally considered to be a clean wood waste unless the wood is treated or painted, stained pallets (like those nice blue CHEP ones) are still classed as clean waste. Many pallet blocks are now reconstituted wood and these are not clean because of the glue used..

Poor wood burning also produces carcinogens, the first documented industrial cancer was testicular cancer in boys who had been chimney sweeps. MDF is woodfibre stuck together and compressed with about 7% glue, plywood uses a little less. Nowadays this glue is formaldehyde based and if the burn is incomplete the PICs from this form into furfurans and phenol like compounds. There are appliances on the market that can burn these wastes as exempt appliances because they burn much hotter than an ordinary log stove. Oddly creosoted wood does not enjoy this exemption, which surprises me because it should also burn completely at high temperature. What should not be burned are those woods treated with halogens ( either as a fire retardent or pesticide) because at temperatures around and above 700C they can reform with the phenol like compounds into dioxins. Dioxins have the ability to replace the linking compounds in a strand of DNA. Similarly any wood treated with a heavy metal cannot be burned in anything other than an incinerator becuase of the volatile species emitted into the atmosphere for us all to breathe. Large incinerators use a number of techniques to scrub these from flue gas and their ash is deemed hazardous. As I said the laws for what a person may do with household waste are quite different from commercial waste/
