I was stripping the plumbing out of a house (that we own btw) on Sunday past. I had mentioned to wor daughter that I would be salvaging the slates off the roof before putting a digger to the house. Daughter says, "Dad, you are not for working on the roof on your own" "Dont be silly I replied" Then I very very very nearly fell out an upstairs window, about 6' square with a 15" high cill and no glazing, unto the concrete yard below. I would definately have landed head first among the broken glass below. Simply went over on my ankle. Shite happens. PS Finally absolute confirmation, shite is the polite way of saying ****, apparently.

That ud work. Manouvering it into the correct position surely a bit tricky though. PS Might need a fatter ram:lol: PPS Secretly jealous cos I haint got a digger to play wi:001_rolleyes: cheers marcus

Is that an older model lovingly cared for Fendt tractor I spied. Looks very clean. PS I found the rest of the post interesting as well. cheers marcus

Surely for that sort of usuage Chris, one should be starting with a 6/10/13 tonne 360 excavator, with a suitable range of attatchments?, but primarily a pincer type splitter, mounted on a "steel wrist" for max manouverability, perhaps? Ideally, in some way with a cunningly (but I dont know how) incorporated hydraulic drive harvester bar included, rotating so as to store up out of the way alongside the dipper arm when not needed. Leastwise for splitting the type of material you describe. Probably difficult to get high output though, perhaps this stuff is better run through one of the humongous Yankee/German tub grinders and turned into chip. Or really really "ideal" Design one with a optical/laser scanning system, backed up by software alogrithims, to recognise size and configuration of individual log, select optimum option of splitting knives, mechanicall/hydraulicly/automatically rotate log to best configuration, split, and either return to beginning of splitting cycle to repeat, if still too large, or split and make into firewood logs. Might need to build a factory round it though, with the size and complexity. OOps, dammn. I fotgot, the Polish produce them already, fuelled by Vodka. And they can be housed in a hut/cheap caravan.

No idea, but not that large, however, a lot depends on the size of the jet, the no of jets? the nozzle configuration etc. Are you relying on the returning water splash for most of the aeration. Can you inject air just before the nozzle for added aeration effect. I am really bored and have nowt else to do. can you tell? Could you consider a wooden water wheel turning in the water to lift and ret the water? via a short "flume". Surely starting with a fountain supplier, finding the size of fountain applicable, then sussing out the pump size, cos, like , you want to be sure of the current needed cos you got a poor/limited supply:lol: Why re-invent the wheel after all. Anyway for that limited size of fountain an "off the shelf" package/kit probably makes most sense.

Someone, must have bin a LR owner? Had/has. "If its not broke fix it until it is"

WoW, Openspaceman, All good interesting very relevant stuff, apparently a bit mare:lol: to burning wood-chip than meets the eye. m

Bloody hell!, that things like a giant Mechanno set. Wonder what the purchase cost was way back in 1995? Frightening I suspect. Probably an overspecced Council vehicle designed by Committee:001_rolleyes:

Beautiful and beautifully thought out and executed, (and btw,I have teased the Mrs. about buying an old,extra extra large but no longer roadworthy Hymer motorhome and parking it up as our retirement dwelling) But? Wot's it weigh?, any idea? Noting the solid woodwork, jawbox sink and cast iron stove:lol: Very homely friendly feel to the interior, proper jealous. m

I like Spud's "life is tough, but it tougher when your stupid" I also liked the comment by yon grizzled old logger on Axemen "Ye caint fix stupid"

3rd valuation is the critical one What is it worth? to you? Or to the other bidder? cheers M

I reasonably imagine it is exactly the question of the small scale of a domestic installation making the necessary technology too expensive for to realize any cost savings. The other rub is wood is known to burn at very high temps, normally relying on a bed of ash to insulate the metal grate, or in the case of a logwood gasifier, the "grate" is ceramic and can sustain the high temps. I am not sure how they get around this in wood-chip burners. Do they rely on the damp (30% for domestic?) incoming chip keeping the grate cool? I dont know. PS Surely the other difficulty is storing the damp chip, it will surely heat/compost if stacked in a bin or store. But again on a commercial scale it is practical to have lorry or trailer loads delivered on an ongoing basis and being consumed at such a rate as to prevent any composting/ heating issues. Also practical on a commercial scale to have a fan blowing cold air through the heap. etc etc

I was and am aware of the particular/more onerous specification requirments for wood-chip to fire an auger fed burner. Leastwise at the domestic scale. Compared to general branch/brash disposal, and I never intended to attempt to burn arb arisings anyway. I also suspect that any chipper I am likely to hire locally will not be suitable for my particular requirments, being aimed at the tidy up/disposal market. So therefore required to buy one, at a substantial capital cost, even 2nd hand. So I will stick with the logs. cheers m

On that particular theme, I had hoped to pick up a grant installed/ripped out sosphicated log-wood burning gasifing boiler. At sensible money=scrap price. BUT If the RHI is "free money" that will allow me to install new boiler (but retain existing flue an other bits) IS it worth the risk. Any one seen nominal 50kw gasifiers for sale, windhager, hoval, froling, kob, any of the reputable makes. Regards Marcus

Well I retained the Wooster Bosh oil boiler. I run it during the summer months, for DHW only. 20 to 30 min each morning and off again until the next morning. For all the oil this uses Solar could not make sense. Cheers all marcus

Thanks all, prob made my mind up to stick to the logs. PS I really really should finish insulating the roofspace:blushing:, 1/2 the hairy molly is still in the plastic. Perhaps the Mice:lol: will have made a start for me.

I do keep telling anyone who asks (or can be persuaded to listen) (i) Insulate, insulate, insulate. (ii) Make sure your boiler, plumbing and controls are working correctly. (iii)Turn the thermostat back to 18 deg downstairs. (iv) Limit the running hours of the boiler forby, i.e. do NOT leave it stat controlled (v)Consider putting a logburner ( NOT plumbed in) in the living room. AND Finally do not EVEN consider replacing an oil boiler with a wood boiler. UNLESS One has an unlimited supply of free wood.

A fair point for a grumpy 54 year old to consider. I probably have 3 years put by at the moment, and would hope to keep this "buffer" in place as I roll forward. I have also attempted to avoid multiple manual handling for this very reason. But "logging" is the only exercise, other than dog walking, that I get, so I had better stick at it. cheers m

I normally keep the egg UP, and the eggcup DOWN. Seems to work for me. PS The Germanic bred Mrs. got these cunning Teutonic Thomas egg cups, with a built in saucer to catch the yolk spillage after over exurberent soldier dunking. Dammned Germans always playing with their soldiers I suppose. Or am I getting old?

I too saw an architect designed from scratch/no expense spared installation Hoval pellet burner in a very new, i.e about 3 year old high spec new build. Get ripped out and replaced by an oil boiler. About 5 year ago. So probably better to stick with the Froling T4 gasifying Logwood option. sigh.

I had considered a wood chip installation back about 8 years ago before I choose to install the logwood gasifier. I have "unlimited" "free" wood so it would not make sense to buy chip. I reckon if I either set the smaller dia logs aside for chipping, or split the larger to size to suit a smaller chipper, I could either preferably hire, or reluctantly buy a tractor powered 2nd hand chipper. I do rather fancy the "automatic" nature of the chip system, even if I had to transfer chip from a bulk store to a hopper, say on a weekly basis. The auto lighting system is a big attraction. I would also retain my 2000litre accumulator tank. However I understand these chip systems are better suited to larger, more commercial sized systems. For domestic use, it all seems to have swung to pellet systems. Must have a prowl on the greenbuilding forum cheers m

Chippers International Erm, I was aware of the brand, but it appears they are aimed at the disposal of brash by chipping.......as opposed to wood-chip biomass production. I would be feeding it reasonably clean lodgepole sans needles or small branches. I would rather hire a machine but this one came up in conversation today with a tree surgeon

For the about to be introduced RHI scheme in Northern Ireland. I got an accepted for a Froling logwood gasifier.............................but Am swithering about a wood chip system instead. I can apparently buy a Gandnia chipper for 6k 2nd hand. Are they any good, as a brand?, and are they suitable for producing woodchip suitable for the automatic boiler feeding systems? I take it substantially more capital investment required? Thoughts please.

Tee Hee, I stumbled across an unlimited free supply source yesterday, about a 1/2 mile from my workplace. A plastics re-cycling centre with loads, probably Ex seed potatoe trade, sitting lonely and unloved. OK Not "free", but well cheap and handy forby. Sorry:001_tt2: Marcus
