Any chance of some pictures? How does it knot? String or wire?

In the days before teram and other geotextiles wire tied heather bales were used under road formations across wet ground.

Many of the track motors have 2 speed by cutting out 1/2 of the cams that the pistons act on, often controlled off a foot valve that also prevents sharp turns when high speed is engaged As has been said anything above a fast walking pace becomes a problem when standing on the platform holding the levers forward with your thumbs

Yea, I can't get on with the wife anymore either:sad:

I cannot check much from home but my 10kW pellet stove id fan is rated at .55A 220V, I'm sure it draws less but my clamp meter will not resolve below 2A. The 150kW woodchip burner has a 160W primary air fan and a 1kW id fan but these are both frequency modulated by the burner controls and will work nowhere near rated output. In my small stove experiments and for my fast water boiler I use a centrifugal fan from a computer (NMB panaflow but I loaned my last two to a offgrid project and now cannot find a supplier) This was rated at .38A and I ran it with a small pulse width modulated controller so it never drew that. I estimated the power output was about 5kW(t). So you see the power draw is quite low for the extra turbulence it added to the fire. It is also well within the capabilities of a thermo electric generator to produce and even though these are not high converters of heat flux to electricity (less than 1% for metal-metal and a couple of % for semiconductor ones) as the cold side is in the airflow no heat is actually lost from the combustion.

Yes natural draught for when there is no electricity is what we need to talk about for the 2 billion people that still cook with wood or agricultural wastes. When we have a grid connection and a low marginal cost for electricity it is a no brainer. Several firms have made stoves with thermo electric piles for fans, there was even one pellet heater. A british firm has developed a small generator that works with a falling weight to power a stove fan, you only need a fraction of a Watt to run a 5kW(t) stove, which is why they named it deciwatt.

Probably not on the small scale, the stoking mechanism and storage gets higher than the cost of the fire box and heat exchanger. That's why pellets got popular. they moved the extra capital cost from the point of use to the pellet mill. Also the bulk density of uncompacted woodchip is poor, fresh branch wood, chipped, occupies about 3m3 per tonne, stacked roundwood is half that and compressed baled wood can get near to stacked roundwood. Chips don't dry very well and they compost to some extent whereas bales dry in a stack outside and shed water much like roundwood does. Chips also offer more resistance to air flow in a burner, requiring, normally, both primary and induced draught fans. Mind I'm an advocate of fans for wood burning anyway ans their electricity cost is relatively low compared with the total heat output.

What form is your incinerator, is it compliant as an exempt device? I could do with upgrading my boiler to one. Anyway bundles of twigs have been traditionally utilised for heat, faggots for bread ovens etc. and it seems the women and kids would gather these behind the fellers. Prior to the victorian demand for hazel coppice I think mixed broadleaved coppice was more prevalent and the rotation lengths increased as cutting tools got better from the iron age so thicker stems could be harvested. There is also mention in "Sylva" of pit burning bavins to make charcoal. A heavy duty conventional round baler was used used in trials in about 2000 but it formed "baskets" rather than round bales. The interest in baling was because of the ability to stack the bales outside at ARBRE power station prior to chipping and burning. Subsequently the fiberpac was trialled, this uses a conventional forwarder to handle lop and top along the axis of a compression chamber and feed it forward, like a stroke delimer. The resulting continuous sausage was bound with many wraps of a self adhering baler twine every 2ft and a chansaw cut the lot into 10 foot bales. The machine was expensive at £250k then and its output was only 80 1/2 tonne bales in an 8hr shift. I saw it working on heathland clearance at Canford. The advantage was the same sytem used for forwarding and hauling shortwood could handle them. It was then on a Rottne base, now presumably it has improved: http://www.fiberpac.se/ After this trial we experimented with making a windrow of coppice which had been discarded after the logwood had been harvested and picking this up with a timber grab, tying off either side of the grab and then cutting into 2 metre lengths, it worked ok but was time consuming. The bales we produced were too dense for river revetment work so we did no more. I did come up with a cunning plan for a baler for coppice waste but never attracted any interest. My proposal was to make biochar and produce heat in a conventional boiler but biochar hasn't gained much acceptance from the authorities as we head into more chaotic climate events... So yes I do think woodland waste could successfully be made into faggots for home heating. I think arb waste is different as there are time constraints and the chipper also loads the wagon.

Bad for your health to smoke at all It's quite difficult to light petrol vapour from a glowing cigarette in the absence of more oxidant. It has a low flash point, so a flame or spark will start combustion but high autoignition point so the cigarette may not be hot enough. gasoil is opposite, difficult to light with a flame but heat it up to above 300c and away it goes. IIRC Daimler was looking to convert a gas engine that ran on town gas (hydrogen and carbon monoxide) for use in a motorcycle. He heard of a lady who was using a form of petrol to get grease off her husband's clothes and sitting across the room from an open fire when the vapour caused a deflagration. He decided that a low flash point liquid would be ideal to vapourise to gas and run his engine.

Blast, beaten again while I was on a long telephone call midst reply

Oruginal copies like mine ( I bought new) apparently trade for up to £400. A revised edition is available : Forest mensuration: a handbook for practitioners

From that am I to infer from the lack of answer on the other thread that the forst is even slower than a jensen 540?

Sounds familiar, a lot of the kit I snagged for didn't stay running past 4 years, often because no one had consulted the people that would have to run the thing and they got bloodyminded. I too had an instance where a chip reception bay was wrong, it was sited next to a wall so the truck would have struck the wall as it started tipping.

They are better than temporary. The thing is the firms, like Pirtek and hydraquip, won't allow them nor will they allow the re ending or joining of an existing hose, it's a liability thing and a requirement of their trade association. I'm pretty certain a LOLER inspection would fail them but for loading ( rather than craning) they should be fine. I have used them since 1978 with no real problems. You should of course get a new length of hose but to get you out of trouble cut out the damaged section and screw one of these on the hose anticlockwise Reusable Socket (top firm BTW and if you need help the chap at the other end of the 'phone will advise, he even rang me out of the blue and told me I had ordered incompatible stuff via the online site) then screw in the fitting, do the same on the other end and get going.

I meant wood that was recovered before the locks, it was to be shredded and fed to a 350kW boiler in the senedd building one of my coleagues sold them.

What are current prices for oak at roadside: Fencing Scantling Planking I have a parcel of about 500hft all cut to <24' and varying from 14 thru to 28QG. 18 years ago it would have been worth £3/Hft thru but now??

Strange thing is the Fassi on a lorry at work is a mirror image control wise.

When I had a bit of an interest down there it was to be shredded and fed to the Welsh assembly boiler

Doesn't look fraxinus to me, more prunus like

Googleearth freezes my pc since last week, some conflict the graphics card cannot handle

What was the tracking like, bumpy? fast? Hard on hands holding levers? Long distance tracking into a job can be painful

From left Slew Lift Jib Rotate Grab Extend Easiest way to get to common knowledge would be with teleflex conversion and two buttons. The firm used to be in Redhill but moved north and I cannot remember the new name.

Makes no difference, if it lifts a person or over a person it's subject to LOLER. HSE also have a position statement on proper cages in place of buckets on telehandlers and it's not encouraging.

but it won't pass LOLER
