Was that the one that turned over when driven at speed around a roundabout near Dorking?

That makes sense Or 4 stumps if the pulley-sprockets are worn . BTW I was quoted £800 for the big Carlton polychain.

Maybe but for a young man it makes more sense to go for the full C+E as it costs about the same.

I've never understood why they use those polychain belts, I'd have thought vee belts would take the shock loading better?

I thought radon needed to be ventilated? My take would be it is do do with occupancy period, a building only used for a short time needs to heat up quickly so low thermal mass. A building occupied most of the day needs a stable temperature so can have a long time constant, typical when using underfloor heating with polypipe embedded in the concrete. Underfloor heating tends to feel more comfortable at a lower overall temperature.

It's only a small component that attaches to the bar so easy enough to replace, if a little annoying. The mushrooms (palm switches) are a disaster, it wouldn't be so bad if just the domes could be replaced but you seem to have to replace the whole switch (80 quid from GM, 40 elsewhere). Mk 1s start on the button, mk2s seem to need quite a bit of churning over. The advantage of the safetraks is where they will go during normal running but this is becoming a bit moot with ALO working rules.

I finally got around to looking at it again and indeed it was the spark arrester blocked as predicted by you two. Much too noisy for our work left out so I burned and blew it clean. Never having come across them before I'll keep my eye out for this problem. A darn sight easier to fix than taking the frame apart to look at the carb which turns out was a waste of time.

This is the idea behind the recent Datatag roadshows for Stihl. Saws get an rf chip, microdots and a barcode sticker. The hope is Stihl will manufacture the saws with the chip embedded. Then any Stihl saw without the barcode will be checked if found.

I thought Freddie Gear's dad made these things from lorry half shafts when they were converting matadors. H&S didn't like them because they weren't retained if something snapped.

It's very dense and has a high water content (ideal to sell fresh over a weighbridge) as it is an oak it is slow to dry. It has a high sapwood content which is very perishable so will start rotting in the stack. Like other oaks it is not very exciting on an open fire. It has a high tangential to radial shrinkage but was known as wainscot oak when used (quarter sawn??) for interior work. Much of the older stuff I felled was too shook to mill.

Cockspur thorn?

Memories of comet 4

Also check the diameter of the disc blades are not under spec diameter plus on the newer 1928s there's a chip breaker that gets bent.

That's my view too On small diameter stuff for something like a paddle I'd try cleaving it into 4 and then reassembling loosely

Our Mk7 crewcab is 150kg more than the single cab Mk6.

Almost bound to be slew piston seals. Straightforward job on my 4510 but the threads into the slew housing partially stripped so had to have local forestry engineer make some reinforcing rods. Clarks had the seal kit.

Most good hydro sites are used and contribute about 2% of England's plus Wales' electricity, more in Scotland. In fact if you calculate the mass times height times gravity of ALL the rainwater that falls on land over 300 metres above sea level you will see even this cannot make more than 6GW if my sums are right, in winter we consume 55GW.

I supplied hardwood to a young GP near Shafsbury who was building his own house and he became so sensitised to the wood dust he had to wear dust mask when working. I'd known him since he was an army captain in Kosovo when he had no such problems.

I was wondering if you had numbers, say alternator to DC to battery charge to discharge compared with pumping water up a hill and then generating electricity through a turbine. Yes any manufacturing has energy costs and pollution but lead acid batteries can have a high level of recycling. Less than 10 years ago people like turnip (whose gridwatch was cited earlier) were spouting forth that solar PV could never have a return on energy used to create the panels (it is huge as it takes a lot of carbon and electricity to get silicon from sand and then refine it) yet we are seeing panels still producing 80% of rated new output after 20 years.

I thought it was a requirement to have some sort of approved sustainable energy on new builds, here the builders seem to prefer air source heat pumps which is a bit of a scam. Having said that modern building regs are much more stringent on insulation and controlled air changes than even 10 years ago. I have also seen quite a few new builds with mock slate roofs that incorporate solar pv instead of some of the slates.

The other thing to consider is that the power in an airflow is proportional to the cube of its velocity. So if you design the turbine to produce its rated power at say 12 metres/sec than you have to stop generating if the wind speed gets much higher. The two nearest sizeable turbines to me are in built up areas but only produce about 10% of their rated output per year, this is no big deal it just means the return on investment is poor. Those turbines in the uplands, which are definitely impinging on my view when walking now, produce about 30%. As I understand it in general they have not performed as well as expected. The VAWT ones at the Ministry or agriculture buildings on my M25 commute past Byfleet seldom seem to turn. I see offshore wind farms from Brighton and up near Cromer and on the flight back from Ulster there was one off the mersey, I find these much more acceptable but the operating costs will be high and life shorter I expect, gives a bit of work to the IRATA qualified climbers though. Please explain inefficiently charging and environmentally damaging in this respect. How many places are left for low cost pumped storage, say a capacity of 7 million m3 of water 600 metres above a turbine? Apart from using less power (we do since our engineering was exported to other countries who happily build coal burning and nuclear power stations) as flat screens, led lighting and better insulation reduce our domestic demand maybe we need a bit of intelligence in running our freezers, washing machines etc. to track current capacity.

Delivered in or roadside? When I gave up we got about 23 for kronospan chip and 29 for stregis hardwood with around 12/tonne haulage and that was 15 years ago. I have about 150 tonnes of p63 blown spruce and pine and may have to harvest his myself but the wood has never been touched since planting so is not under any schemes.

I refused to use SBK in gasoil with wander leads from a tanker and 2t pump when they were still spraying off Hazel coppice over-stood western hemlock planting, lost my job. Many years later I bought some standing chestnut coppice of poor form in a nearby FC wood, you could still see the frilling marks from a similar programme and no softwood other than a few straggly stems. I think the problem with the stuff used in Vietnam was mostly the sheer scale and direct contact but it was also a cheaper formulation which was contaminated with dioxins in the manufacturing process.

I misremembered that it's Gold under Gorse Bronze under bracken and Hunger under heather

I hope to find some dry when I tip up in Belfast at lunch time! Yes Gorse is associated with free draining sandy soils here in Surrey.
