Sounds like most of our UA blokes, did he also have the congenital deformity of a spur attached to his ankle?

The point being that many stoves are just boxes where single skin metal surface is the only heat exchange. stuff a few baffles in the bottom and temperatures are maintained, flue gases thengive up heat to the top after combustion is complete. A back boiler low in the stove removes heat before combustion is complete because water is some 400 times better at carrying heat per unit volume. A properly designed back boiler and wood burning are contradictions in terms as the boiler bit needs to be after the combustion chamber. This is different from coal burning because of the different ratio of volatile gases given off so most of the heat is from secondary combustion.

There are three Ts you need for a for complete combustion: Turbulence, the gases must be able to mix well enough to ensure an oxygen molecule meets a fuel molecule. Time, the gases must have enough time to complete their reaction before they get too cold. Temperature, the reactions will not complete if they are quenched. This last one is what a cold spot in the combustion chamber can do. An illustration of this can be done with a candle and spoon. A candle wick is self optimising in that it is designed to curve out of the flame, where it is protected from oxidation, outside the flame it burns and so its length remains constant and the flame remains clean. Hold a spoon above the flame and it too remains clean. Lower the spoon into the flame and it robs heat, becomes a cold spot, what happens to the spoon?

As I understand it if you can prove the device complies with the current regulations, which is done by composing a technical file, a person wishing to market the device can sign a declaration of conformity (which should not be done lightly) and then CE mark the device.

Our one was in the shed by 1974. Scott the foreman said you had to pull a rope if it went wrong.

No this is a fibreglass guard shaped in a horseshoe with a conventional nozzle on the outside of each leg, it attached to a standard cp3 backpack sprayer on the hand lance. Push it forward so the tree is guarded in the middle, spray, turn through 90 degrees, spray again, carefully back off to avoid any drips on the tree and move on to next plant. The herbi just did a 4ft swath in the middle of the rows, held just above the herbage it produced a fairly large drop that didn't carry to the crop. The ulva 8 was the one you held above head height and allowed to "incremental drift".

Dolmar had a purely mechanical version, my foreman had used it but I never got the opportunity to see it working. It wound its way up a tree high pruning selected quality tree and when it reached a set diameter it came down. http://i16.photobucket.com/albums/b7/traktorist2222/JuergenSchwarze300406/100_2123.jpg I think it was called a tree monkey

And not much problems using the arborguard, still got one hanging in shed roof, not used since 1986.

Which parts? I think everything aprt from the slewing gear is repairable. Osbornes at Ower were importers.

I thought Tilhill had a huge biomass facility at Lasham?

Fortunately not my decision and as most employees work remotely they have to take vehicles home. One firm I worked for had two buttons on the dash, the white one was for use in work time and the black in personal time, I don't know what they did. The same firm had cameras front and back to record driving and accidents.

I doubt there has been a case yet but we were warned by an HR consultant that we should be open about which vehicles were tracked, especially if they were used solely. The reasoning is that data is collected and linked to that person, so it is relevant under both Human Rights and Data Protection Acts.

I ran low on wood so brought some fresh ash home, I was surprised by what I found, a 2.093kg 1/4 section felled just before Xmas started out at 31%mc wwb. I kept it by the stove where it reached blood heat during the evening s and plotted the weight. On the 24th I dried it in the microwave and it has regained about 3gramme a day since. Plot below: I'll have to try the same with some oak. That's going a bit ott,I'm sure 16% is the ideal for a number of reasons but the loss due to moisture between 32% and 16% is about 4% of the available heat.

Yes it is legal but if you do it covertly you may well end up attending a tribunal with a claim against you.

You'll end up with a problem if you track an employee without making clear the vehicle is tracked. I have used 3 different types of trackers on plant and vehicles. The simplest and smallest is the cubetrak, you send commands by sms and you have to pay the firm that hosts the server for credits for sms and position reports. You log in to their server and see where your tracker is and has been. They recently changed policy from allowing to top up a few thousand points at a time to monthly top ups and it has become uncompetitive. The second is the cheapest to run and just takes a payg sim and responds with either a text message or you can call it and get a position and status. This proves very cheap to run at <£15/annum but had a high initial cost of £500, I have seen similar which are much cheaper now, they are basically the guts from a smartphone. The one that tracks a fleet of vehicles and sends alarm by e-mail on the smartphone (works well but only beeps once and I have slept through without hearing it) costs £240 and about £10/month to run. The companies server creates all sort of reports, especially about vehicle abuse. It reportds position every 5 mins or 2km when the vehicle is moving. All of them only report the last position the gps saw and only the fleet tracker indicates if the device is connected via gsm and if it is seeing satellites. In theory one could set up ones own server and put ones own sim into a unit but I had enough trouble just getting a gsm switch set up to talk to a server so I could access over the internet plus the data sim will cost about the same a month if you access it a lot.

Others have answered but it is to do with the fact that propane needs heat to vaporise and this is normally provided by the ambient heat, if you start drawing off gas too fast you will see a frost line on the bottle, as the bottle gets colder the gas cannot vaporise. On forklifts and auto engines (like my V8 LR) the propane is taken off as a liquid and is vaporised in a coolant heated regulator. I reckon about 2kW of heat needs to be delivered to keep the landrover cruising. The LPG firms are reluctant to supply gas for bulk tanks that have liquid take off because it might be used for on road vehicles. They will supply hot air balloonists though. Also gamekeepers tend to get very good deals on buying gas in 47kg because they use so much.

Yes, parbuckling, the standard way to load timber before cranes.

Not any more, no coordination in the arms, kept winding one handle wrongly It may be worth asking the recently retired founder of Fuelwood, he worked on them when they operated out of Atkins (Sp?) quarry near Betchworth. The son in law of the old man that took the business on from Paul Elsey also worked on them and ran one out of Ockley. From what I remember they were pretty basic, an open circuit 3P series pump driven by a ruggerini and solenoid operated spool valve. This powered a similar sized motor with 2 bolt sae flange and standard 9?? tooth spline coupling direct into the drive pulley wheel. I still remember Paul shouting to me up an ash tree in Greendene to ask if he could have the stem to try his new invention on, around 1983 I guess.

That picture reminds me of how we bent the leg on my mate's engine crane. I preferred the timber grapple, lift all the stakes out pick up a couple and spin them around pull the wire in like spaghetti then drop the lot in a bonfire, return when cooked to scrunch the wire up and weigh it in.

I thought standard practice to mitigate damage when the detector indicates metal is to mark the position, mill from one end as close as you dare and then come from opposite end to a similar safe point, split board off with wedges and test if it contains the metal usw.

If it is basically well engineered then collating a technical file and putting a CE mark on is no big deal, probably expensive if you have to pay someone to produce one, there are plenty of firms that do this. The one piece of equipment I researched a technical file for had a number of small discrepancies which I did not think were acceptable, someone else still marked it though. Anyone remember what CE stands for? Caveat Emptor IMO:001_tongue:

Thanks Kenty and now I've read the tfl site that's confirmed. I shan't be looking at the iveco on arbtrader as a result, because it's registered 1/1/6. What it doesn't say is when the next level of restrictions will apply. I'm guessing that all >3.5 tonne commercials registered in UK after this date of 1/10/6 are fitted with euro 4 engines. As it has been mentioned that modern trucks meet euro 6 how long will a euro 4 be allowed? I note that trucks being used by a firm I do work for must be using adblue, simply because the old containers are being used to deliver chipper fuel to the site, a bit worrying with regard to water contamination of fuel if they're not dried out thoroughly.

When are the rules changing again? At the moment 04 plate transits seem ok but what about <7.5 tonne trucks like iveco how recent a model would I need to buy?

I doubt my 084 did 40 hours, I dropped it for the regular saw as soon as possible, it wore me out and drank fuel.

I saw a one eyed pea green RB44 near Fox Corner's oak monolith today at 16:30. Is it 24V?I still have an unused electric off a Dennis fire-engine.
