Not for cleaning stove glass. probably better for dealing with stray virus at the moment Expense when water is good enough for fly ash and oven cleaner for tarry deposits, which of course don't happen with a good burn of dry wood.

Which is a logical development and why petrol engined chippers may become more viable, having a lower capital cost and the difference in fuel cost will be less. Longevity of engines may be an issue though. Also domestic heating will be excluded and therein lies the problem, whilst there are few domestic properties that use pressure jet burners anyone that does will be able to have red delivered. As I think we established horticulture includes work in domestic gardens (and I wonder if the current position statement on allowing that roadside hedges and trees can be worked with agricultural tractors using red diesel will stay) we will have the problem that if you take your diesel powered machine to work at a commercial premises then you may not use red.

Main advantage of twin rear wheels is not having to worry too much how the weight distribution lies between the axles

'scuse my ignorance but if the insurance company know what its used for and the value is agreed what difference does it make apart from 50mph on single carriageways and 60mph on dual?

It's not so much a difference of opinion but rather a difference in preference, there may be a number of good reasons for preferring one power head, simplicity and capital cost being a couple. We had a thread a while back on whether one could run different power heads at each end but in essence it's similar to pushing a broken down car, you may be big and beefy and able to exert a force of double what an 8 stone weakling can but would you turn down their offer of help. as you will both be working at the same speed because the car won't move any faster even though you may be doing double his work he is still contributing a third of the total.

I would worry that as ash contains silica it would be a bit abrasive and might dull the glass. I agree with most that just an occasional wipe with a damp cloth gets the build up of white fly ash off. If something has gone wrong and there is a tarry build up it will normally burn off in the next hot fire but something caustic , like oven cleaner, will shift it. You can make a solution of potash (less caustic than oven cleaner which tends to be sodium hydroxide) by passing water over wood ash in a coffee filter

@renewablejohn have you experimented with grades and translucency of the sheet for covering polytunnels? As I said I was proposing corrugated PVC as a longer life cover and high light transmission because it works so successfully at my home but woould like suggestions for best cost-lifetime cover. I think the wood will sustain about 80 tonnes/annum for several years and adding value would seem to make sense over selling in the round.

Ideal for that, it was so tempting to use a top handle one for that job. If I were going for a new saw a conventional handle one like this would be ideal for home logging, quiet and when the battery runs down I could have a rest rather than fill up and start again.

No one left to answer to now. The MF35 always was a pig to start, the later 35x with the three cylinder engine was better. Before I got to it it had been left with no antifreeze and a piece had cracked off the block by number 2 injector, I araldited it back in and ground off the lump so the injector clamp no longer bore on it. That one ended up being sent to Pakistan, after I had used it to haul elm cord wood on the buckrake and various other jobs.

That worked for me for 35 years, mind I tried to get it delivered in rather than roadside.

Seems reasonable to me, the disease is out, low mortality in the under 60s and the viral pneumonia is treatable in intensive care, so the slower the spread the more chance us oldies have of getting a bed in ICU.

The hydrogen from the ruptured bags went upward and only burned as fast as oxygen diffused into it, your oxygen and hydrogen were premixed as they were produced at anode and cathode of in the same cell. I did the same with our old MF35 in 1972, I knew both batteries were knackered so I was in the habit of sticking the starter boost on my oxford welder across the terminals I disconnected the clips before switching the welder off.

Nor would I I do too and cut and split them, none of it sees the inside of a kiln Tell me more, I know of a couple of heat pump installations that were abandoned but then I know of a few chip and pellet boiler installations which were failures. I know when I sold logs that none of my customers used them as their main heat and at £100+ for a bulk cubic metre I cannot see how they compete against other commonly available fuels.

Too right mate

More likely it will put them off buying logs

I don't see the definition of "efficiency" in the context, we used to use the same terminology as is used for heat pumps, coefficient of performance, and that measure was the amount of heat necessary to remove a kg of water from the wood. @Squaredy is right about the waste and it is true of much of when we burn fuels which is why there have been combined heat and power schemes over the years to attempt to address this. Most of our fossil fuelled electricity comes from combined cycle gas turbines, these use the waste heat from the jet to boil water to turn a turbine, and manage to gain 50% more power from the heat. We could do similarly with kilns in that the hot moist air leaving a kiln at, say 40C, could still be used in an underfloor heating system but it's a question of increased capital cost verses cheap heat. Given that a furnace is going to put out 1200C+ there is lots of scope for cascading heat when you are drying wood at less than 100C but the added complexity costs.

If you heat wood up it does give off Volatile Organic Compounds before pyrolysis starts at about 330C and yes these will burn. They are likely the things bugs get at first as wood rots and of course these are what you smell as you heat wood up. We used to reckon the loss of chemical energy was insignificant below 125C.

? It's what I hope to do for a small woodland heavily infested with ash dieback, subject to planning, but I will use bits from a polytunnel and possibly clear corrugated pvc sheet rather than polythene I regret not doing this for a little extension I built between my shed and garage but otherwise the insulated profiled steel sheet does well and no problem with condensation one gets with the plain sheet.

I hope we don't have to go down this route but it does seem a pretty low energy device for such a good performance, any idea of the cost? In my situation getting onto the chimney to service it would be a bit of a problem.

Good idea, make a bender with a transparent sheet and get some solar gain too.

Here's one that seems odd to me: Motorists remove barriers to avoid 28-mile detour WWW.BBC.CO.UK Immovable barriers are installed at the site of roadworks due to last all year. While they're sitting pondering what to do for 45 weeks why can't they stick the bed of an old low loader and some armco sides over the culvert and control traffic with lights and a weight/width limit?

Perhaps your only hope is finding others with the same problem and joining in a class action
