I don't know what you lot are talking about but I liked Liz's processor

Actually out of all the members there must be many more lurkers over 60 but I was trying to remember those regular posters who have admitted being of advanced years. BTW are you still up for my visiting the family home town (Plymouth, Stonehouse area) and dropping it?

If they only have chainsaw and axes they would be better off having an arb company drop off logs, shame they're not in SE Surrey as I still have a large heap of odd sizes.

There’d only be 5 of us posting!

Bumping this: I got a Mak 5121 and it seems good. What difference from the Dolmar PS-5105 especially the weight? The dcs5121 seems a bit heavy for all day use but I need to do a weighing for comparison. I have an ms261 where the clutch side crank bearing has gone after 2 years and something has worn through the pump housing. I need to replace it with a similar weight saw but simpler as the lads are a bit rough on saws.

Practicality Brown in Iver used to take some in but it's many years since I've been there.

Yes before moving to the butcher’s. In those days a 59ac chain for the Danarm 110 was more than a week's wages and he was the only discounter, advertising in Exchange and Mart. Sometime around this period he had invested in an electric rivet spinner.

Funny my experience was different Nitwork Rail accepted quote with NPTC qualificaions and method statement accepted, their principal contractor's elf rocks up as it's their worksite and demands two anchor points, much loss of productivity and neither pc nor nr will foot the bill for time lost double rigging.

Interesting one that; if one has said the work will be done using ropes and harness anchored from the top and NPTC units 38 and 39 why would IRATA be necessary? OK so you are not suspended from the tree being pruned but does that matter from a safety point of view? What is the practical difference apart from the fact IRATA uses two anchor points and IRATA accepts anyone with any chainsaw proficiency?

I got told today I wasn't qualified to make up chains because I hadn't been trained. It's sort of true because I was only shown how to do it in 1974 by a one eyed bloke in Haslemere and didn't start making my own till much later. Is there a required qualification?

Gael. I like Paleo Alto version

Char from forest fires is a natural part of the soil but most of the wood has burned to ash and the char is only a thin layer on wood that has not completely burned. Producing biochar potentially increases the char yield to 25% of the dry matter mass for sequestration. Only 15% of this is truly recalcitrant but even the higher tars that form the remainder have a fairly long life in the soil as microbes devour them.

No but many of the TLUD designs will fit into an existing device, like a pellet stove, it's the batch loading that's a bit of a drawback plus in UK it's quite hard to maintain a supply of 10%mc chunkwood and as the mc goes up the char yield dwindles. Both here and in Canada we successfully demonstrated converting conventional woodchip stokers to produce a high char ash and delivering heat into the system and this is the route I would choose. As I have mentioned before, given the total heat energy being the same, there is no great advantage in burning wood at between 1200-1600C and then heating a building to 21C when the higher temperature heat can do a little work first. The issue normally is that extra complication adds capital expense and everything to do with burning wood is much more capital expensive than burning gas. The problem is not having the skill to market the biochar. We made biochar for many experimental plots, including using seaweed at East Malling research station, and results were inconclusive. It seems to benefit much poorer soils than we have here where structure has been lost and there is little SOM. EA were worried about its retention in the soil as small particles may be abraded off and carried into the water system, they mentioned worries that fish may be affected, they cited that sharp sand lost from building sites had been shown to graze fish gills. To the poster that thinks the collective actions of 7 billion humans going about their business of exploiting the resources available to them don't make a noticeable impact I suggest you think again as you journey to work and look around you. How many people succumbed to skin cancer as a result of the hole in the ozone layer expanding? Also consider the plateau of stable temperature we have developed our societies in these past 4000 years are most unusual, maybe anthropogenic as agricultural lands were cleared of high forest, and were always unlikely to last.

Yes and this is because in our soils trees can access the nutrients they need so are limited by moisture and light competition. Fertilising can cause problems in producing growth that does not harden off and suffers in the winter.

They've done very well since they turned up on various forums in 2008 asking about how to do it. Their crowd sourcing model and open sourcing a lot of the designs and still growing a business is fantastic.

They did the same around here cutting to waste 60s schedule D plantings of pine on heathland restoration. I think it really shows how inappropriate government subsidies can be.

We used similar slashers cut down like this for marking selective thinning with a blaze either side of the stem.

Using virgin wood would get it out of the waste regulations but wouldn't address the other issues of applying it to land commercially which is why I proposed selling it as a PAS 100 amendment. This was the whole basis of our various projects, about 50% of the energy in the feedstock remains in the biochar but we managed to run a gas turbine briefly on the offgas. Even if this motive power wasn't commercially viable ( it probably was in the right circumstances but we were not businesslike enough in our dealings) it still produced good clean heat. At the domestic level one could heat a house and add the char to a kitchen garden.

My prices were for fitted at the local garage and don't include VAT. I cannot answer your question but the transits that we had clutches done where the DM flywheels were considered worn and replaced with solid seem OK.

Is it the same as this http://arbtalk.co.uk/forum/chainsaws/33857-whats-your-bench-today-684.html#post1135405 If so I could let it go for a charitable donation.

Depends on the state of the DM flywheel. I was quoted £850 for clutch and new DM flywheel, £650 solid flywheel and clutch and £450 clutch only, 09 plate already on 2nd head and clutch at 200k miles.

I normally won't indulge myself in this sort of thread but this one caught my eye as I have a bit of an interest in the Environment Agency and their pension scheme. Yes the government will have appointed people from commerce to head this first steps agency as they try to devolve it from government. Plainly such people will have a background and bias toward industry rather than policing the environment. I don't see we, the public, can do much other than see the governance remains within the law. Now biochar is something we can involve ourselves in because whether we believe climate change is anthropogenic or not we can agree that doubling the atmospheric CO2 content in 200 years with an amount equal to 45% of this atmospheric increase in CO2 dissolved in the surface waters of the ocean, which is having a demonstrable effect on marine life, is unlikely to be a "good thing". Because the additional CO2 from fossil fuel use has not been dealt with in the normal flux of the carbon cycle, for whatever reason, our intervention in turning a small portion of the annual carbon fixed by photosynthesis into a recalcitrant form can make a difference to redress the balance. A young Dutch girl concluded from a desktop study at Bangor that were we to carbonise plant wastes which are currently composted or burnt we could offset 10% of UK's carbon emissions to atmosphere. When I was more involved, before having to take up employment because I am a poor business man, it was EA rules on applying wastes to agricultural land that prevented large scale application of biochar from wastes because the jury was still out on whether it was beneficial and there were concerns about run off entering the surface water system.

My brother in law bought one, as a Daiwoo, about 10 years ago (X plate), as you say it had a merc engine, automatic, towed well and had a long guarantee. He didn't do may miles and scrapped it at around 100k (mostly electrics and autobox problems) last year.but it did work out fairly cheap motoring overall.

All the best for your speedy recovery Sean

It's not banned for commercial use once it's thoroughly in the wood. The point is because it is phenolic it is a carcinogen, so best to handle it with gloves. This mutagenic propensity may be part of its effectiveness. Horses don't seem to gnaw creosoted timber like they do the copper based ones. Nowadays creosote isn’t coal tar derived like it was in the days every large town had a coal gas plant so it may not be as deadly as then. If you are treating an absorbant timber and have no access to a pressure chamber you can hot and cold dip it. The principle is to have dry wood so the cell sap spaces are empty of liquid, heat the post up and the air in the clls expands and leaves the wood, allow the wood to cool in a bath of creosote and as the air in the clls contracts it sucks the creosote in. Pressure treament systems apply a final vacuum to suck out excess creosote (VacVac process) as creosote is expensive and to leave a dry surface. In the old days having the creosote catch fire was a regular occurrence, I would have liked to try a flash steam coil to run the heating and reduce this risk.
