  1. My view also, seasoned loga are a luxury good, you are not selling on strictly energy. Woodchip is sold on energy price plus an uplift if subsidy for burning it is involved.
  2. Makes sense, they were working on about 18p/kg 20%mc wood you are charging 30p. I used .7m3 builders bags and they only had 300kg of green wood in when I test weighed a fresh load.
  3. The FMV came with a float valve but the Cranab just had a tap between the hoses. Trouble is that in float on the trailer it would fall off the load or the hose fittings would get bashed so normally easier to fold the loader behind the cab.
  4. For picking up and trimming stake material (after cleaving or in front of the peeler as well as stacking) I used a muller billhook with a notch filed in the sharp end.
  5. You must remind me to deliver the one I offered!
  6. I don't understand the question but 1m3 of solid wood is 27.736 Hft IIRC.
  7. It's too simple to need one if L is the length and QG is a 1/4 of the mid girth then =L*QG^2/144 dropped in a spreasheet gives Hft Who still uses Hoppus feet?
  8. It may be that SHP isn't licensed for the wood if it is painted or otherwise contaminated. Most of the big incinerators can only take residual waste (domestic stuff in black bags) and they charged £80+/tonne a few years ago. One on the south coast would take things like sleepers at a gate price of £50 which is £79 worse than the £29 we were getting for virgin chip at SHP. Just do the figures for for maximising the contaminant content to be within the rules in order to put a bit of waste into the virgin chip heap. The giveaway with sleepers is the smell but you could also see the odd blue fleck from a chep pallet or a bit of chipboard.
  9. I have lived in Surrey all but two of my years so they may be local. I associate rue and shaw with surrey-west sussex and hanger with Hampshire. Probably but whilst I might say "that is a nice cant of chestnut coppice" I wouldn't say that coppice on yonder hill but rather that copse. They were wrong there then because a copse is by definition a wood that has been under coppice management, the terms copse, coppice and coup all derive from the French to cut. Spinney need not have been under any management
  10. It's a carr rather than a spinney then.
  11. Coppice is the practice, copse is the result. Just like thicket is a wood at a certain stage of maturity, spinney is a clump of blackthorn, hanger is a wood on a steep bank, gill is a wood on a bank leading to a stream, shaw is a strip of woodland between fields (as is rue) etc.
  12. It's still running on demolition timber rather than virgin wood, I'm guessing this is because they can get enough and be paid for taking it plus the virgin timber they were burning attracted the NFFO subsidy and as this was a pump priming grant it ran out after a number of years.
  13. Possible better writ as =Pi()*(d*d)/4 and bunged in a spreadsheet or =Pi()D^2/4 Hoppus is an interesting measure. Hoppus was the chap that bought timber for the dockyards and his system was based on the measuring tools readilly available. I imagine the average yard would only have one accurate measure (a steel yard??). Hoppus would have the middle of a log girthed with string, this length was then folded twice to give a quarter girth which was measured off against the steel yard. Similarly a piece of string would measure the log and be held against the steel yard repeatedly to get the length. The calculated volume would then have been read off pre calculated tables. Now whilst you cannot cut a 50ft3 beam from a 50Hft log you will get approximately 50ft3 of pieces in total including bits of scantling cut from the slabwood, so it was an intuitive measure, unlike m3. Another nicety of using the string to girth an oak log was that you could fold the string into 8ths, discard one 8th and then fold the remaining 7/8 into 4 and use this as the qg, the answer then was a good approximation to the underbark volume.
  14. Yes and all you'll manage is to squeeze some water out No There are two mechanisms that hold pellets together in the absence of glues, one is the heat and pressure causing the lignin to plasticise and reflow, setting as it cools, softwoods have higher lignin content. The other is similar to how paper holds together, the fibres are so close together that weak (non chemical) hydrogen bonding occurs. Wood with no air spaces between the fibres is about 1.5tonnes/m3. a 1.5 tonne piece of dry softwood will have a solid volume of 3.75m3. So to get the fibres close enough together for hydrogen bonding you have to compress that 3.75m3 to 1m3. ...and paper is also heavier than water.
  15. On a slight tangent; my sheeting blew off my stack at home and I have been amazed at how the logs have absorbed water.
  16. I suspect their NFFO subsidy ran out, nowadays the big coal burners will be hooked in to one of the new tarriffs.
  17. That may be so but I was commenting on Honey's list, and they are a dealer I used to frequent as a forestry contractor and still do, occasionally, as an employee of a small company. When I was in business there was no internet, I paid cash and bought from three local dealers, all of whom were friendly. I also have to deal with our local Ford dealer and would never use them by choice.
  18. I don't forgive bad attitude, the rest I can work around given time
  19. It's not traditional ( it was an exchange field for a road scheme) because it is a small field adjacent to the common and even with 4 animals grazing the density per acre is much higher than a traditional common wood pasture.
  20. There is a field near here that has been reverted to wood pasture management, animals were not grazed for 30 years and now are only allowed in for a few weeks after September to nag the grass down. It has reverted to predominantly sallow and oak with bramble under and some grassy glades. So if you do go for protection why not fence bits off and plant desired species not likely to self seed from the existing trees, allowing these to develop naturally?
  21. Do you pay a pump price with a discount or is the price calculated some other way?
  22. I have a hda 87 c2 from a 262
  23. Details passed on. Sorry for delay I was late back from yard. I think 5 people have been given contact details now so that should close this thread.
  24. No they were their own thing by then, I was referring back to the early 70s.
  25. They have been cut to 5ft to get them on a farm trailer, at end of a long farm drive at Shalden, you may be able to back an artic in but best phone the estate chap, pm for details
