  1. Yes, Stihl bar straight on with another link in the Stihl Micro P chain, plus sprocket change.
  2. May have to buy some off Ebay ?
  3. Is this the best air filter for milling with an MS 660 Panther mill running 3/8 Lo - Pro ? 0000 140 4402 Air filter HD2 Thanks
  4. Thunder bolts - predrill the timber, then masonry drill through the timber into the concrete - impact wrench Thunder bolts straight in !
  5. The legislation is on the table to dissuade anyone selling firewood green, part seasoned or dry seasoned by any other measure than by the industry standard - m3.
  6. Agreed and I should have made it clear that some kilns dry at lower temperatures. However some kilns dry at temperatures up to 130c and volatiles start to migrate over circa. 105c. I still stand by my view that the concept that force drying firewood is an environmentally good way to reduce atmospheric pollution is flawed, especially as many producers are burning waste wood over 20-25% MC. Understandable that if you have invested in the process you will wish to keep business as usual. The next generation of producers will be larger scale operations, mainly farm based who air dry all products, that said there are a surprising number with that setup already - far greater initial investment of course.
  7. It is because the construction industry uses many species of timber. Wet basis measurement is not mentioned in the vast majority of pin MM's specifications as their core market is surveyors and the construction industry who all measure on a dry basis.
  8. No you can't. Mwet = Mdry / (100+Mdry) Mdry is the MC on a dry basis. Yes it does - Firewood and Forestry - Wet basis - Always. I have found the most accurate way to pin test to date is split the log, measure ACROSS the grain in the centre of the split face and at each end of the split face 2" (5cm) in from each end. Measuring the outside of the log gave no usefull data that actually represented the actual MC of the log. Add the 3 readings and divide by 3. When compared this result with oven dry method it gave reasonable correlation.
  9. I think you will find that your Pin Moisture Meter measures on a 'dry basis', which is the wrong type of meter for firewood or forestry. You need to obtain the correct meter that measures on a 'wet basis', which measures the water in the firewood (a solid), expressed as the weight of water as a percentage of the wet solid. Pin Moisture Meters designed for the building trade are the wrong type for you.
  10. Quite agree, calorific value is, even though the FC keep banging on about it. There is a table that documents the wood types and species dry weights, but time has passed I I cannot seem to put my hands on it. Have you a copy perhaps?
  11. Rarely do I get offered Hemlock and when I do they rarely know if it is Western or Eastern Hemlock. Is there a significant difference Firewood wise ? I know the calorific value is similar to Douglas or Larch, but as it is years since any arrived here, so does anyone know if it dries as quickly or burns as well as them? My experience of Spruce is it dried out to nothing and burnt leaving no ash and I have a suspicion that Hemlock burns well but leaves little ash also.
  12. It's only at 5 as it burns away faster than the others - that said the amount of kWh it produces is not that much lower than the others.
  13. I have been offered various Softwood species recently apart from the regular species and I am trying to determine which species come out on top for the Fastest to air dry and the species that generally burn best when air dried. Here are my findings for the - TOP 5: DRYING Larch Douglas Monterey Cypress Leyland Cypress (Lleylandii) Hemlock BURNING Douglas Larch Monterey Hemlock Leyland PLEASE COPY AND PASTE YOURS.
  14. So what are the several advantages of kiln dried over say air dried firewood at 16% MC, as I am struggling to find them ? I can honestly say I have never had woodworm larvae in any of our firewood logs. So how do you assess the MC of the Kiln dried and the air dried you sell - by Titration testing or wet basis moisture meter?
  15. The only research I would trust is direct from a University who have no vested interest in the conclusions. We all know that leading stove manufacturers have been telling consumers to only burn kiln dried Hardwood for years, none of which is sustainable. Most stove retailers promote only kiln dried hardwood as that is what they sell. Basically it is common knowledge the fastest way to dry timber is with airflow, heat ideally the 2 combined. The poster needs to basically mirror a polytunnel - solar gain from the sun and very good airflow with the prevailing wind blowing through the stack. Worst scenario possibly is wrap in plastic.
  16. For doing what the man is asking, yours is the most sensible estimate. Loading the log deck takes minutes so the poster may as well do that himself which basically cuts out all the skilled element of the vacancy. I would trial a few for a day each on firewood production guaging their productivity and that will soon sort the wheat from the chaff.
  17. Yes, many people who are not linked to bureaucracy know that circa. 25% MC is perfect to burn and when compared to the 'scientists' graphs, shows only a marginal difference in kWh produced compared to 20% MC. After factoring in forced drying etc. to achieve the required sub 20% MC, in reality particulate emissions are no less when burning wood at 20% MC. Stubby, all our noise is falling upon deaf ears, we've just got to lap it up or some make just keep their fingers crossed - it's a simplistic as that.
  18. In their eyes what do you see the difference as?
  19. As Woodworks posted above in his excerpt: The requirement for wood sold in volumes under 2m3 to be dry (less than 20% moisture) will apply from 1 May 2021. We recognise that small wood producers may struggle to meet the requirements straight away. Given this, small suppliers will have an extra year to comply (until 1 May 2022). " or does one have to prove it via (say) yearly audits from industry assessors " The powers that be can turn up unannounced at any time or following a complaint from a customer with a moisture meter who claims the Firewood sold to them as ready to burn is not below 20% MC. Don't you just love legislation - Grrrrr
  20. 'agencies all work in collaboration, so for a start you have the eyes and ears of the Police, LPA's, Environment Agency, DEFFRA and Customs and Excise to name some.'
  21. I take your point, however this is related to the Firewood Industry, that is what the legislation applies to that is now regulated by Woodsure. The sawmilling supply chain is another matter with different legislation. I didn't draft the legislation, I am merely reiteration the information I have been given, right or wrong that is for the individual to decide and challenge if they so wish. Perhaps you have had meeting and have more current information than myself, as the last meeting I had was nearly 2 weeks ago. The feeling I got was the matter is not up for discussion and the legislation is coming into force at the current documented timescales.
  22. Double standards it may be, but to gain the Certification, which by the way, is now planned to cover all firewood sales, basically you will have to follow their rules. The "Industry" said that 20% MC was an ill founded MC level and 25% MC achieved the same level of PM emissions as 20% MC when forced drying, additional infrastructure, additional transportation etc. are factored in. Unfortunately the 'Industry' is 10's of thousands of small scale producers who have not the time, money or energy to contest the legislation. There is know Industry body I know of who are interested in taking the Government to task. Remember the 'discussions' that informed the legislators were held between DEFFRA and the big players who all force dry their timber. I fully support the original HETAS 25% MC threshold, that is a sensible level that we all can attain, but I am powerless to influence the legislators decision of a maximum 20% MC.
