Might as well bury or cover them to stop algal growth. I got the submersible pump out to pump water from the capped well into two butts today as they were dry.

En route Ongar to Swanage

I wonder what insider trading was done

Even my chinky cheap one would do that, especially if it has been cleaned a bit. I would not attempt doing anything to it with a saw unless I was determined to split if, then I would do some deep plunge cuts from the top face and hammer some wooden wedges it. A very long spade bit drill is easier to sharpen than a chain if I wanted to get through it. The thing is a stump is a higher quality wood and interlocked grain because it has to resist all the motion the stem transfers to it without splitting.

Yes but it doesn't explain why ; either it's because the cambium isn't thick enough to support a breeding gallery or because it becomes too dry for the grubs. Back in the day when Thetford pine was coming on stream ( probably before the FC moved from scots pine to higher yielding corsican pine) there was a roundwood depot at Brandon. All the surrounding pine trees were stunted from chronic attacks from pine shoot moth (IIRC) that had bred in the timber stacks.

I don't expect it is deadwood that's a problem but that recently felled logs big enough to provide fresh breeding galleries that remain moist enough to support the grubs. If they are small they will dry quickly and the grubs cannot live on dry wood. Similarly a healthy spruce will drown the bugs in resin but a sickly one will not. Insects seem to have a better ability to find a stressed tree to invade than us.

How is that collected and chipped, it must be broke up and muddy?

When I started thinning young FC pine plantations we were not allowed to leave anything thicker than 2" or longer than 6' in the wood, this was so that the wood would quickly dry to prevent infestation by the pine shoot moth. I wonder if better forest hygiene or whole tree harvesting of spruce would remove breeding habitat.

probably not straightforward; ignoring someone can be done by setting a flag on your query to the database of all posts, just like how it recognises posts you have already read, whereas quotes are linked to an un related post. Similarly it might be nice for an ignored user not to see your posts but equally difficult as it would require a reverse look up.

Me too Stubby but a year older. I didn't get any qualifications and got into forestry late as agriculture wouldn't have me. Started harvesting on my own account aged 28 IIRC. I came across three time served toolmakers/ machinists. Something must have happened in the late 70s to cause them to come into forestry. Dale would reproach me for allowing my files to rattle around loose and Anthony shame me by using his verynear to check the length of the cutters every 3 sharpens, both better fellers than I. I manage a day every now and then, this week I was back redressing/shaping/lifting the 25 year old widely planted broadleaved plantation, wore me out. It was a crying shame cutting decent birch poles to waste when I would have liked the firewood.

Have you seen if Whitehouse would rebuild it? Generally I always repaired stuff as I was happier with the devil I knew rather than having to spend time looking for used machines again.

If I'm working and need to remount a bar that has a ridge formed I draw file with the less well worn ends of a round file. I have never used a dressing tool and have been tempted to close a worn groove but never convince I could uniformly overcome the springiness of the steel, so replace bar with new. I have damaged more bars than I have worn out.

That one doesn't have the reinforcement to stop the hand hold from splitting. That type I remember had a steel rivet passing through the hand hold with washers each side.

Well done, I bring a few homers back when I cannot get the job done in the couple of hours our repair cafe runs. Rust steel swing seat in my garden in mid repair today. As has been said tool handles were often cleft, not because it was easier but because the grain is more likely to be continuous where a saw can cut across and leave it "short grained". I know scythe handles were steamed to get the curves but I imagine some were straightened similarly to make rake handles.

I thought their main function was to prevent erosion and entrain silt to form a stable bank. I attempted to make firmer fascines by compressing them with the grapple loader. The EA (IIRC) guys rejected them because they couldn't drive stakes through them.

It was a "united we stand , divided we fall" message . I think it was Mussolini that picked up a stick and broke it and then picked up a bunch and showed the crowd he couldn't break the bundle,

Yes but I think those who got their full licence after 1997 have to ask for BE to be put on the licence, else it should be added at renewal.

Sorry my mistake I should have looked back a bit further and seen it was @JMA46 that was wanting to supply direct air to a 21kW boiler.

@Rob_the_Sparky has explained why it is best not to rob heat from a wood fired boiler and I never saw it done on the commercial chip stoked boilers, or the smaller batch fed gasifying boilers I dealt with. Also they were never room sealed as they sat in dedicated boiler rooms, so the air was drawn in from the highly vented room and the exhaust was drawn out by fans after the heat exchanger had cooled it to around 115°C. I am not saying it couldn't be done but balanced flues run concentric to the air intake in ss pipes and only for a short distance. The OP says he could take air from the loft into the chimney then down to the boiler, all I am saying is it should not take heat from the flue and a fan would be needed to maintain a depression in the boiler (so any leaks could not allow combustion gases out and to eject the exhaust at some speed to get it away from the building as it would have less buoyancy than a normal wood stove exhaust ( as they tend to be hotter than boilers' exhausts. There may be regulation and practical difficulties as well. What I should have explained is that with a gas boiler the aim is to condense water vapour in the exhaust in order to extract latent heat from it. Gas burns more cleanly and only gives off water, CO2, Nitrogen, some O2 and a little SO2, the condensate is mildly acidic and gets drained via a plastic pipe. Wood is more difficult to burn and gives off a whole rake of acidic compounds, if these condense in the flue they will eat through a stainless steel liner.

Perzactly

Can you elucidate, I don't understand the question? Also how do you define efficient? Is it how close to complete combustion of the fuel different heaters get or how much of the heat ends up in the living space?

Very sensible. I don't have much to do with climbing ropes but should have done the same. I had hoped it would be possible to splice a new novoleen 50m onto the unused end of mine, Youtube videos seem to show the possibility but probably beyond my capability. Also there is noticeable wear on the capstan which is probably from muddy rope.

I have not looked at pictures, am busy for once; I do not know what happened to the Arboricultural Advisory & Information Service at Alice Holt but the Forestry research there have the lab facilities.

I generally agree especially about incoming cold air cooling the flue too much and causing condensation of water in the exhaust. Even if the flue continued a few feet above the inlet air the path would be too torturous for the buoyancy of the hot exhaust to drag the cold air all the way in. In principle (apart from the condensation issue) the concept is the same as on a modern gas boiler, with a balanced flue, but that has a fan to drive the process. So I think it could be made to work with an induced draught fan at the top of the flue, driving the exhaust up away from the intake as well as creating a depression in a room sealed stove to suck the air in, whether it would meet building regs is another matter.

Surely it has the label attached that show the rating? Most ratchet lashings have a label marked in daN (dekaNewton ten Newtons) which is near as dammit the same as a weight in kg. Breaking strain will be about double the figure.
