  1. Hi, the fuel cap on my 078 is leaking, out of the central hole in the top of the plug, the threads seal fine. It bubbles out under slight pressure after using and leaks if left on its side. Is this designed as a pressure release valve or can I just glue it up? Anybody know where to get spares from to just replace it?
  2. Quicker mounting, you can swap chains without taking the bar off the mill, more ridgid .. For adjustability do you mean moving the nose clamp closer on smaller bits of wood so there's less flex in the bar? The only other thought I had was drilling out the rivet that holds the nose on and bolting through there..
  3. Just checking, I've just got a 36" sugi bar for chainsaw milling and I'd like to mount it with bolts rather than clamping it on, where is the furthest point suitable for drilling towards the nose end? Apparently on the stihl bars you can drill in the center of the nose but I'd be weary about doing that and ruining a sprocket..
  4. So we should use engineered plastic rather than a few sheaves of willow? .. What's wrong with a good stiff bit of cloth?
  5. From what I've read that's an issue for 4t engines but not 2t, since they don't have valves and also have the 2t oil mixed in for protective function.. I still think it's worth a shot in a junk saw!
  6. kelly kettle or a coleman stove .. WITHOUT CASE NEW 2014 COLEMAN SPORTSTER 11 533 DUAL FUEL UNLEADED PETROL STOVE 2 | eBay Either way you're not lugging around separate fuel.. Coleman has quite a ridiculous power output for such a small stove too boils a kettle well fast.
  7. Correct me if I'm wrong but .. 1) It's a narrower range of compounds -good -bad? 2) Density is similar 3) Vapour pressure is wildly different but could be due to different test temperatures 4) Flammability is similar Other concerns could be storage and corrosive effect on rubber etc. But for camping stoves people seem to think it's a good equivalent and that it works similarly to aspen and burns cleanly.. anyone from the US use coleman fuel in their chainsaws? (Just had a quick google and it appears people do ..)
  8. So from an msds (looks like there's 'fast' and 'slow' degreaser) this is the fast .. Naptha (petroleum) hydrotreated light Boiling point 105-135 C 760mm Hg Density 710kg/m3 (petrol is 710-770) Vapour pressure 4.2kpa 20C Flash point 11C closed cup Auto ignition temp 283 C Flammability limit lower: 0.8% upper 6.5% Pulled from ARCO standard unleaded petrol msds: Boiling point range 26.67 to 221C Density 750kg/m3 Vapor pressure 48-103kpa Flash point closed cup -42C Flammability lower: 1.3% upper: 7.6% Pulled from Aspen 4t MSDS: Naphtha (petroleum) full-range alkylate butane-contg Naphtha (petroleum) isomerization) Boiling point range 35-195 C Flash point < 0 C explosion limit lower: 1% upper 8% Vapour pressure 55-65kpa @ 38C density: 690-720kg/m3 spontaneous combustion >300C So all looks pretty similar, could be interesting to get a junk saw and try it out! Might well be that that fraction is worse for fumes, could burn pretty cleanly..
  9. Ok so this is a bit out there .. but I was looking up fuels to use for a coleman stove and a lot of people were suggesting either Aspen 4t or 'panel wipe', which seems to be pretty much the same thing, distilled napthalene. Now could it also be used as a cheap clean chainsaw fuel? It's a bit cheaper at ~1.70-2.10/L and seems to be clean .. Has anybody used this or other alternative fuels? Only issue could be that it has the wrong octane/hexane rating? Although I'd love to see what an insurance company would make of it
  10. I've also seen some pretty big diamond shaped flying beetles burrowed right inside some rotten leylandii before ..
  11. Most pallets within the EU should only be treated with 1) Heat treating or 2) Methyl Bromide, not particularly nice stuff .. Have a look on the side of the pallet and it'll say "HT-MB" or just "HT". Of course you get all sorts of far east imports, I've even had mahogany pallets before ...
  12. Only really been seeing some mushy boletes, a few chanterelles and the occasional psilocybin about, not much else notable! It's been a while since I've had any chicken of the woods either ..
  13. Thought it might be of interest to somebody here.. Liner Diesel Bench Saw | Aberdeenshire | Gumtree Looks like it'd still have a fair capacity?
  14. A few of the oaks are showing mildew, it's probably that oak mildew disease, is there any point in trying to treat it while they're small or will they do ok anyway?
  15. Growing quite a few trees from last seasons seed, not got round to collecting any this year though. I have a few trays of acorns that were just put in in the autumn, the rest of the bag was horribly neglected, left in a plastic bag outside. A few months later I looked in the bag and all of them had 3" long roots sticking out so gave them to a friend out by huntly who's planted them all on his land. The ones I've got all are doing pretty good and stand at around 8" tall already. >95% germination rate. Also got a couple trays of rowan and elder seeds that were stratified in the fridge and worked amazingly well, all popping up when they should've done, the elders are getting slugged a fair bit but a few surviving and the rowans small but soldiering on. Don't know where I'll put them yet but got plenty of friends with bits of land who'd appreciate them. Also got some yew seeds still sitting in the fridge. Probably going to be working tree planting later on in the year so hope to get at least a 5 figure sum of trees planted out
  16. I was really curious if the work had killed off the tree but then I saw your location
  17. Get an OBDII reader and check the computer's VIN against the plated number and the one in the V5?
  18. your roi on oil production is very little and more technical, sure if you have a plentiful waste stream but seeing as most folks here have a waste stream of medium sized bits of wood .. Esp. for forestry makes sense powering your operations with waste products.
  19. So does nobody else wear waxed cotton waterproofs? For sure they can be a bit heavy and not for summer days but they've actually been the most breathable waterproofs I've used and they stand up to a lot more wear and tear.. Especially for waterproof trousers, they're only about £20 but you can charge all day through any amount of brambles and not the slightest rip. Otherwise if it's summer just a base layer works brilliant for me.
  20. I was thinking a small tractor with a nice perkins etc diesel on it with a ****** fuel system but otherwise all good, requires conversion to run on spark ignition with high compression ratio and the most fiddly bit is the controls for your 'carburetor'. But all together not too implausible and plenty of open source designs out there. see GEK - About Us - GEK Gasifier GEK Wiki / Summary of Genset Options for Wood Gas Have a bulletproof PTO generator and biomass chunker and a few acres of medium rotation coppice and you're pretty set up for when the oil runs out ..
  21. Also produces nice size fuel for an imbert-style gasifier ... this has been my next project in the pipeline for a fair while, will get round to it some day!
  22. Do you still get a decent crop of chestnuts with medium-rotation sweet chestnut coppice?
  23. Well it was a toss-up between that and avium .. unless you're going for something else like cerasifera ... but then I'm crap at blurry morphology /me retreats into corner
