I sold it 35 years ago but only ever used leftovers. Eddy Stobart started out with logs before he found better ways to make money,

Can i still get my certs after a long delay?
openspaceman replied to billy_wizz's topic in Training & education
I'll bet you haven't read the regulation? I was replying to the op's specific case and I don't want to open a can of worms but do feel the "arb establishment" have made a lot of money out of this interpretation and spawned their own private industry to feed on it. The health and safety at work act says people must be trained and competent. PUWER requires employers to undertake that training. Now in the OP's case he is self employed so is covered by the 1974 act and he has been trained and shown competency to the level of a nationally recognised qualification where assessment is carried out independently of the training. He does not have the ACOP "recomended" certification. I would still advise he was re assessed. -

My guess would be that you are covered under the 1974 H&SaW act as being assessed as competent to do the work. Not having the paperwork will mean no firm would employ you. -
I wish, I got iton my left arm from the calves kept in old wooden buildings when I was about 24, GP gave me a topical tar based treatment that did nothing and within months it was over my shoulders. It needed a systemic pill to kill it. My boss, an old man of 30, had it worse, it gave him a brazilian! It's the same family as athletes foot

Mine started and ran on lpg from cold

This was the idea behind brash baling, search fiberpac, basically make a long compact sausage of brash and cut it into 3metre by 0.7 diameter cylinders, forward these and transport them with conventional roundwood gear. Stack them outside the power station and chip them as and when needed. In 2000 the machine only managed 80 1/2 tonne green bundles a day and with a capital cost of £250k it was uneconomic.

That’s right, noisy but strong

Best LR gearbox imo and not built by LR AFAIK. I ran mine for over 10 years on LPG and overall still worked out cheaper than diesel but had no further use for it.
-
Yes it was green plovers that followed the plough here and they are long gone from local fields
-
A decade before that in our first geography lesson we were told oil would only lat 40 years and then we would be back on coal which we had 300 years reserves.

It reminds me of how far ahead of the game Jonsereds were in the late 60s as well as how potentially dangerous saws were then. My first gang leader was a bit older than I am now, he started during the war, and he slipped up on bluebells with a danarm and carved off his calf muscle. It had healed by the time I worked with him but just the shin bone left.

Weather and climate change - Met Office any good?
-
Yes I just do it by eye to decide a route, mine are simple line of route. If you have postcodes or use the nearest post code then you can put them in a route planner. I have not used these since I first connected a garmin 45 to a laptop using win95 but there are apps now and MapQuest Route Planner amongst many others plus many coordinate converters like Get the GPS coordinates (latitude and longitude) of an address or place and get directions to/from that place

I don't understand the problem but then I've only come across load sensing on more modern kit and never needed to delve in to it. I thought load sensing just adjusted the pump output to match the pressure and speed the spool fed the cylinder. On a simple open centre system the control would be by gently bleeding oil through the spool with the remainder bypassing the cylinder (and heating up in the process) and going directly to tank, load sensing avoids the waste heat?? A simple swash plate pump used with an open centre valve is normally controlled by its internal system to deliver a constant power. As power is flow times pressure this meant in practice it delivered full flow at no load and then as pressure built up flow was reduced. I'm about 40 years behind the times when I was looking at these system as FC were developing their all hydraulic skidder. Having said all that I borrowed a JD tractor and nearly boiled the oil with my logsplitter some years back, never did understand JD hydraulics.

Is there scope for adding insulation? Are you having too many air changes? What sort of temperature logging do you use, FJMatt posted some which indicated he may be dumping too much warm wet air.
-
As the feed is to a motor the return will be the same volume so it should be possible to TEE a supply from the return but below reservoir level and return must be below the fluid in tank or transmission. If the winch motor has an automatic (failsafe on no pressure) brake then the spool should be a motor spool with ports connected in neutral.
-
Mike and VMD supply the joysticks in the earlier post, makes a cheaper option than a joystick and box for the voac valve chest and should be superior with ramp as well as max-min
-
Yes I use them to plot railway access points and the nearest post codes. They don't have the detail that the 1:25000 had but with the contours added (as provided by mapmaker) you get a fair idea of the lie of the land. You can also construct a map using all of your georeferenced diagrams and the render them on google earth using mapmaker.
-
Agreed but you should keep the resistances low and if you are using a remote valve to feed the winch do make sure you return it to the tractor via a low resistance, not through the return to a spool valve.

Nice but cheaper with bacofoil. Probably better control with a separate fan and humidistat. That's right, all the energy the dehumidifier uses gets dumped back in the kiln but the electricity costs several times more than the wood heat. If you have a simple kWh meter I'll stick it on the drying room at work and weigh the water produced. I have done this before but cannot find the figures though I remember it was not as efficient as expected, My guess is they work best around 20C and one that worked at 40C would use different mass and pressure of refrigerant (do car air conditioning systems vary between hot and cold territories?). It's still my preferred method of drying clothes
-
One Certainly Would think of going that hot Which is why I gave the caveat about the heat source! My old boss Gavin ran his chip dryer at 40C as this is what he could recover from the coolant of the large reciprocating engine they were planning to use. If you are circulating water at 90C down to 70C on the return then I reckon you could run a kiln up to about 55 without ridiculously large heat exchangers, Lorry radiators won't last in a pressurised circuit but I have some air conditioning units that need someone handy with soldering joints which must be good for a few kilowatts. Are you wanting to pre dry chip in front of your boiler or venturing into logs? If the latter I can sell you the raw material :-)
-
120-125 C because once water approaches boiling it also loses its viscosity, go higher than that and you start giving off volatile organic compounds and above about 230C you are into the early realms of pyrolysis (torrefaction) and high oxygen content organics like acetic acid are given off. The higher than boiling temperature give a differential across the log to get heat into the middle and boil off even the bound water.
-
Define optimum? Broonie posted the best temperature for speed some months back. Otherwise it depends on heat source and air circulation plus size of log. Wood chip will dry in 40C 40%RH in a few hours but a 2kg log will take several days.
-
Sounds like it's 2 or 4wd with no difflocks, what are the axles from? Many rough terrain loaders were based on standard agricultural tractor parts and the difflock may be present in the axle but not selectable.

Doing something useful with the flared offgas is essential IMO. Overall we could do with a more holistic approach to our use of burning fuels for heat and charcoal making lends itself to using the by product heat to dry something and the heat from the dryer to heat something like a house. Consider dry wood will achieve a flame temperature of 1600C though in practice keeping the combustion chamber around 800C saves damage whilst allowing a clean burn yet we use it to warm our houses to ~25C, all different temperatures but the heat flux is the same. So there is scope for running the heat users in a cascade. If the wood you wish to char is fairly uniform and dry then a inverted downdraught gasifier (aka Top Lit Up Draught) will yield 25% of the original dry weight as char and a clean flame (which could do the drying).
