It should be on a label on the driver's door jamb. I cannot check one atm but its 67psi on front and 44 on back IIRC for 195r75c16 on a 350

We used to send first and second butts to Nidd Valley, which was a long way to haul from Surrey. The coloured stuff pesumably was used for settee frames. Yes but I suspect it was used a lot more before plastics, it was valued for treen and dairy work, I cannot say what the demand was as even this may have been a low volume market. It was valuable for veneer and of course fiddlebacks if rippled. I grew up in the steam train era and the carriage interior wood was all a deep mahogany brown, I was surprised when I got on one of the carriages being restored by the Bluebell Railway to see the panels were a light tan and sycamore, presumably the patina had developed from pollution and tobacco smoke.

Was the square cut out to check for ripple? A polish chap I worked for had the deplorable habit of doing this to standing trees. The butt looks like it has flecks from squirrel damage?? Anyway the saying was fell it Xmas eve, deliver it Xmas day and mill it boxing day. The inference being that all this should be done quickly and in the winter. The old guys also said the sawdust should be brushed off the boards and they season vertically but I don't know the reason for this latter unless it is to do with the compression from stickers.

I do like the look of that valve, mine has suffered badly from hitting " contraries"

I cannot imagine any way one could arrange logs in such a way they could occupy more space than when they are randomly dropped in from a processor. As to regulation; I work in a sector that is heavilly regulated, the net result is the client whose system we work to has less choice of firms qualified to do the work because the entry level to the system is expensive and the jobs cost considerably more than in more normal environments. When I worked with commercial biomass installations the designers fitted heat meters to the system, the plan was to pay for woodchip on the amount of hot water it would produce. No suppliers would supply on this basis bar one special case. It was a shame as there seemed to be a ripe opportunity to cut transport costs by electing to be paid on the meter.

Yes it sounds like a seal has failed on one of the slew rams. If you can get them off and there is no scoring it's a straight foward job

Be aware its relevance to firewood logs is loose in that it deals with measurement of trees and the relation of volume to weight. Its purpose is to provide practical mesurement for sylviculture, the practice of growing trees for their timber. Firewood logs are a luxury good not a primary energy source. Production of firewood logs requires a high labour input, each time a piece of wood is handled adds to this labour cost stacked firewood demands even more handling.

If you allow 50% air spaces the volume of loosely jumbled logs in the above example would weigh 343.75kg which fits reasonably with the original poster's experimental value of 366kg for slightly higher mc logs. Of course there are lots of other unknowns, for instance if the crate were larger there would be proportionally more weight in it. Most of this is explained in the forestry mensuration handbook (Forestry Commission 39 "blue book"). One could do the same for other hard and softwoods. Then you would have to consider differences in calorific value and this varies between species and parts of the tree (smaller branches have proportionately more bark and this has higher ash content). Perceived wisdom is that oven dry hardwood has about 18.6MJ/kg (5.166667kWh/kg) whilst the wood of a douglas fir has more lignin and resin and will be about 20MJ/kg (5.555556kWh/kg). After that you need to account for stack losses and these will be mostly interrelated and due to moisture content and excess air (higher mc wood needs more primary air and hence leads to higher excess air values).

Yes. To clarify; I bought a 1990 ex mod ragtop V8 110 in July 1998, put a hardtop on and ran it till 2009 when I stopped working for a living but I kept it sorned with a new MOT every year until I sold it last weekend. It had 80,000km on the clock when I got it and sold it with 165,000, it needed no major mechanical work in the whole time I used it but I did have to replace a couple of outriggers.

The problem would be in overcoming the float valve which stops you over filling the tank, so you would need a pump capable of working in lpg at ~80psi

I ran one for 10 years, parked it up for the last 5, and sold it last weekend. At the time it was far cheaper to buy and convert than buy a similar diesel and it had similar power (109bhp v 111hp) subsequently the diesels have developed far more power so mine was a bit sedate. I do have an RR engine with about 150bhp but never fitted it. See above not necessarily higher performance. If you factor in the service interval and the clean burn using lpg (a mate sent some oil in for analysis and could extend oil changes to 20kmiles verses the diesel every 3k) and I was getting 14mpg on lpg when a diesel would do about 25 mpg the fuel prices were very comparable. Mine were under the driver's seat and in one of the jerry can lockers (ex MOD) gave a range of 150miles with no compromise on off road driving. I thought it was getting worse in Surrey with a couple of outlets closed down.

Probably too late to change but I had big problems with a bottom unloading silo. The drag arms being run off the auger sheared the auger after 4 years. The sloping auger will increase stress. I'd look to putting a second motor to drive the arms. This set up is fine for pellets but arb chips have a propensity to have a negative angle of repose i.e. a cavity will form rather than chips drop to the sweep arms.

sold my 110 hardtop last week and it did me well for ten years. no major repairs and never let me down in 80k miles. Only let it go because I hadn't used it since 2009

Chap up the road from me seems to do well out of it £200 for a 10 tonne tipper load and he wins some of it from his skip business. He often has a struggle supplying during wet weather as the screen cannot cope.

Fine and easilly checked by chucking a log into a water butt. Are we assuming this solid m3 does not then shrink as it dries to 20%? Blue book give the basic density of beech and oak at .55 and .56 and defines the basic density as oven dry weight divided by green solid volume. so the green solid m3 has about 550kg of oven dry wood in it. OK that allows 30% air spaces, seems reasonable The weight of the solid m3 of hardwood is now 550kg plus the 20%moisture, so total weight is 687.5kg, i.e. it has lost 312.5kg water whilst seasoning. It now occupies a space of 1.429m3 stacked. So a 1m3 stack of 20% mc wood will weigh 481.25kg

Rod is spot on, problems tend to build up so just one out of spec piece is unlikely to jam the system, I managed to lose a 13mm combination spanner and the auger passed that even though it was longer than the pitch of the flights. Over time we had more problem with fines packing in the auger trough than twigs jamming. Having said that I would advocate a simple oscillating screen to get over length stuff out of the heap but I have never had a budget to do it. More of a problem is with fine material not having pore spaces to allow primary combustion air up from the grate. This is exacerbated with damp chip which needs much more primary air. Essentially burning wood with a <25% mc is a doddle because it really only needs over fire (secondary) air as worse case is you carry char over to the ash which is good for the soil (biochar). On the large scale very dry wood can cause problems with slagging on the grate or overheating the grate which meant some flue gas recirculation may be necessary. Of course an arb chipper can be used, I've managed to stick a tonne of ash wood through a Forst into my hopper in less than an hour. With the roller speed set low it produces a fine chip.

I've had mixed results with weedwiping but not a problem from run off. Back a while farmers would hand rogue wild oats in a corn crop and later a glove with a built in weed wipe was developed. I'd always wanted to try one to increase the contact area delivered with chemical. I'd try some sort of weed wipe, wait 15 days and then strim.

Same here. Sometimes we would fell and take the cordwood as payment.

As I read it they can gross 3500kg on the truck and still pull 750 trailer. Also can pull a heavier trailer as long as the MAM of vehicle plus MAM of trailer do not exceed 3500kg. The bit that changed seems to be that tests passed after 2013 cannot pull a trailer heavier than the unladen weight of the vehicle. It still strikes me that anyone intending to work in this industry would be advised to get the B+E licence in quick succession whilst the test mentality is still fresh. My last driving test was 45 years ago and I would have to work hard to pass one again.

My TP960 chipper produces a nice chip and is very adjustable, Runs OK at 100hp. I also have seen a damaged repairable TP280 recently.

That's what I've done, but not often as it is time consuming. I used stuff grown from coppice to get the basal curve. I didn't know the 8 rings per inch, I thought the faster grown the better. Holly was also used for hammer handles as this is also apparently springy. There was a good trade for ash for hammer handles up till a steel strike in about 1984 when production of whole hammers was shifted abroad.

We knew it as the Norwegian Flip Flop winch, I asked Ted Radford at FASTCO if it could be included with wedges and felling levers as a tool for assisted felling but got nowhere.

Ah, ok it's more what the eye doesn't see... Ducts still make sense for this though and if you lose the string a sandwich bag and a leafblower works for 100 metres.
