53% in hallway at 16C and 40% in sitting room at 19C here. We do have a mould patch inside the front door caused by a winter jasmine wall plant which I like so put up with a dark spot no one can see. My topdon android attachment is a cheap way of spotting cold spots.

Yes I can see that from what you say, the only advantage in that case would be that the incoming air was likely filtered and because the house was at slightly higher pressure no dust particulates would blow in when a door was opened.

Yes but condensation becomes a bigger problem as people keep doors and windows shut to prevent expensive heat loss, especially if they dry clothes on radiators as tumble driers (spit) are too expensive to run. Damp tends to occur in cold corners where the temperature drops below the dew point of the air which people are breathing out. This is often at the bottom corner where the cold bridging between walls and floor happens and is often wrongly diagnosed as rising damp.

Not really as I was unsure of what it was, Mechanical Heat Recovery Ventilation is what I think @Conner is referring to and in a well sealed house is a good thing as it sucks moist warm air out of the house, it exits via a heat exchanger and warms a similar amount of cold air coming in (this which lowers the relative humidity as it warms, thus effectively drying the air). Water which condenses out drips down a drain. Some even have in built heat pumps that drop the old air temperature below zero and the warmth this produces goes back in the house.

not to mention taper

Two faces of the same coin. The electricity companies have "bid" to reduce the demand for the grid at much the same rate as the "peaking" generators would be paid to produce the energy. The electricity companies then pass on some of this "saving" to their customers in order to time shift the demand away from the peak period. This is largely because the wind has died down and by 16:30 solar PV cannot contribute. I am told not having to switch on peaking plant avoids a cost of £3/kWh. As it is a cloudy day I will have to buy some electricity today so I will buy it in early afternoon and not need it from 16:30 to 18:00, or indeed for the rest of the night.

May be better to use electrolysis in sodium bicarb to retain most of the original iron

Bacterial canker wound which has been aggravated by birds seeking out bugs?

Acids, like tannin, will react with stainless in the anaerobic conditions inside the hole and similarly with zinc too. As SS will need to be a larger diameter for the same strength this should lessen the problem. I never did any rod bracing and only a little wire rope stuff (and all prior to 1976) but I would have thought it better to pull the top together high up before tightening the rods (with large diamond washers under the nuts in my day).

Too late the rods look like they are already installed on the pictures but lousy mechanical advantage compared with a brace higher up.

Yes I was thinking rivnut but not having seen a 260 for several years I can't remember what goes on there. PS I wouldn't consider splitting and rebuilding a saw that old, especially seeing the chafing wear on that spring, too many other parts to consider

The cell water becomes a more concentrated solution of salts as water is withdrawn in the autumn, this more concentrated solution has a lower freezing point plus I suspect the cells become plasmolised so if they did freeze the increased volume would not rupture the cell wall.

You might PM the site as I may know it

No it will have got lighter so less return. The chestnut thing is a specialist market and the produce has to be selected out of the tree lengths by someone with an eye for seeing which bits of the tree are best for the assortment of produce. For instance the bottom of a piece of chestnut coppice is often swept, so either cut an 8' post or discard 2' to give a 9" top 10' length which 6 rails can be cleft from.

In my day chestnut was worth far more than firewood when selected out for cleaving, 10' rails being the premium product. £60/tonne for fresh felled hardwood by the 18-25 tonne load seems good to me, collected in June not so good.

Thanks again, it had been puzzling me all morning and I had hoped someone with understanding of MEWP mechanics would chime in. I had decided it was possible by using counterbance valves rather than check or overcentre valves. These would need the full pressure of the hydraulics to the opposite side of the ram to develop before oil would be let out, this would labour the pump somewhat but if the boom became overloaded it would lower. before it snapped. The only thing different from normal this would need is for the spool that controls the lift to be a motor spool (i.e. both services connected to tank in neutral).

Unlike bigger countries you cannot get away somewhere to kid yourself you are in the wilderness, so they spoil the view, same as with electrification of railways. In the past even in SE England most buildings and infrastructure were hidden by trees, not so with Turbines or overhead wires. Still it has to be done and should have started fifty years ago rather than 20. The objections about non schedulability are spurious because until we actually achieve surplus RE we remain dependent on fossil fuels and existing CCGT are very good at load following as are turbines easily curtailed. As to cost there is little doubt in my mind that wind and solarPV are currently the cheapest electricity with nuclear running last and way back in the race. In fact bearing in mind our nuclear fleet are owned by the french government as are the two under constriction by the chinese and I am chauvinistic enough to think the money would have been better spent on domestic PV and srorage. I too like small scale and as a result only buy some electrcity for for 4 months of the year, even in those 4 months I self supply 50%.

I'm with @coppice cutter that old stove is not worth having, especially not as an open fire as you will lose more heat up the chimney from the house, The difference I have seen quoted is 20% of the heat gets into the house from an open fire whereas a modern ecodesign stove will get pushing 80% into the room. An open fire just sitting there looking pretty in a centrally heated house dumps loads of wasted heat up the chimney. BTW even if the back boiler is filled with sand it must never be sealed.

Its a smaller capacity engine ... I have never used either but that 10cc difference should be noticeable, obviously best power to weight is the ideal irrespective of capacity but price must come in to it also.

Yes mine too I'm not so sure about good paying it out, because they know the contract and the law they use that knowledge to limit the amount of any claim, especially in regard to "betterment".

Assuming fresh ash is 35% mc 615kg

Yes but how? My point was that there is a check valve on each ram port that won't let oil out until there is a positive pressure at the other port, there must be a relief valve on each of these also.

Never having overloaded a mewp it was fascinating to see how it lowered slowly, it would be interesting to see how the valves on the ram prevent lowering in the event of a hose failure but still allow oil to escape when overloaded ( this is normally done with a port relief valve at the control but that won't work with a check valve on the ram). Or did the operator lower it??

I have always taken the view that if your tree falls onto your neighbour's garden and there was no signs it was likely to happen then you should remove the trespassing parts of the tree back to your land. If the tree was obviously likely to fall then you have been negligent and should also be liable for any damage done. Interested to hear about the actual legal position. I would only contract with one party for the whole job too.
