  1. As I said you need to reverse while steering from lock to lock so the front diff turns more than the back
  2. I disagree,I don't think much of the transmission brake on LRs, big problem for the unwary jacking them up on sidling ground and a leading cause of rear half shaft failures on series LRs,
  3. I wondered if wind up was the reason that the 2004 hilux had a dog clutch on the output of the diff because that never seemed to have the problem
  4. Yes as @Woodworks says it normally becomes very noticeable as stiff steering, the effect also leads to much increased tyre wear if used on tarmac. If you get onto the tarmac and find it won't pop out of 4WD the procedure I found best was to reverse whilst turning steering from lock to lock. Else jack up one wheel with the handbrake off. What happens is the induced torque from the wheels rotating as different speeds causes friction between the dogs that engage 4WD so they will not slide apart and disengage.
  5. We found there was very little they could do without direct witness evidence of the littering unless items in the waste could be traced back to a commercial undertaking, when chain of custody requirements meant a prosecution could succeed. Anyway apart from the general consensus that the law could be ignored what has been the effect of the legislation on sales so far? Has it succeeded in reducing pollution which it seems is acknowledged to have been overstated for wood? Is less wood being burned? Have many stopped trading in firewood?
  6. Strange I only remember as far back as the coronation😉
  7. That may have worried them that you only saw the job as short term
  8. Aren't clay subsoils in the SE still recovering from having water squeezed out of them by the weight of ice 10000 years ago?
  9. May I interpret that as you will get a mortgage taking into consideration your income from the current well paid job then move on to a heavy goods driving job which you find more appealing for less money? I still don't understand why a man of your mechanical abilities was not sought after by one of the more mechanically oriented tree firms.
  10. Not me but heat is heat no matter the source, pollution and heavy metals are another matter.
  11. I agree with @Woodworks that a dehumidifier won't be effective. The reason I asked if the RH of the outlet air was tested was to see how close to saturation you were getting, the aim is to get to near 100% saturation at the lowest temperature you can get down to. For example ( and I'm picking these figures from thin air one would have to consult psychrometric tables to get real numbers) it's 15C where the kiln is and the air going in is at 60C, the air coming out should be around 20C and 95%+ RH. If the RH leaving is lower it means the air is not in contact with enough log surface and hence is not picking up enough moisture to be efficient, similarly if the exhaust temperature is higher then not enough of the heat input is getting into the logs. I used to use earlier versions of these Temperature and Humidity Data Logger - EL-USB-2 WWW.LASCARELECTRONICS.COM Temperature and Humidity USB Data Logger
  12. It probably needs more recirculation within the kiln and maybe smaller logs. Have you measured the outlet air for moisture saturation?
  13. In that case I wouldn't worry as the pressure from the fans will far outweigh any difference in buoyancy of moist air and it may be that heat is better conserved because as the warm air picks up moisture it cools and cooler air plus water vapour will fall even given water vapour is lighter than air normally.
  14. Me too but it's early days yet as I don't get through much.
  15. Remember what the dormouse said
  16. I was more into folk blues including cohen, dylan, pentangle, davy graham, lightfoot, than heavier stuff but liked Grace a lot after Woodstock, I will have been with US conscripts in Germany for a short while then listening on the 8 track to Steppenwolf, Lauden wainright, Arlo Guthhrie, Buffalo springfield, Beacon street union, Doors to name but a few. ( Ruby was banned on the base). Overall I was optimistic, only now do I realise how misplaced, who could have thought things would get so much worse.
  17. I guess I heard Jimi's version long before Dylan's original, always liked it especially for the lyrics, rooted in Ecclesiastes I think.
  18. The simplicity of those single plane push rod V8s is what appeals to me about them. It's what I'd chose if I wanted tens of hp, else for one hp a B&S (spit) side valve. In fact a long time back I came across an article about a guy who was running a V8 on steam, the exhaust exited via the coolant galleries to keep it all warm. IIRC this was one using a bump poppet activated by the pistons to allow high pressure steam in at eitheh side of TDC.
  19. Things are bound to have come on in the gasification field over the last 80 years especially with modern control electronics The cost advantage must be considerable now. Any more details available?
  20. there are some among us who think life is but a joke
  21. Good luck with that. Modern engines are intolerant of dirty fuel and people don't expect to have to take the head off (easy with an old side valve engine) and scrape off the tar deposits every thousand miles. It did look like a group in California were getting close to producing a clean offgas of CO and H2 but even they went quiet, as have the earlier posters on this thread. PC20 Power Cube - ALL Power Labs WWW.ALLPOWERLABS.COM The Power Cube PC20 is a sensible solution to the critical global need for low-carbon energy, using agricultural and... It would be interesting to see a hierarchy of heat to motive power devices to compare comparative performance. I'll start with the proposition that steam turbines don't compete under about 600hp. An eccentric but prolific self taught engineer in Ireland is posting a series of his Heath Robinson but serious attempts to generate dry steam from wood and power a cylinder for a small railway engine,
  22. I'm not familiar with these kilns but is there not a fan blowing fresh air into the kiln?
  23. Mostly inability to pay competitive wages as the business loses work. The thing is, unless you've bought a lemon secondhand out of warranty, cars are incredibly reliable and have long service intervals so cheaper to replace a vehicle at 8-10 years old than repair it.
  24. It's what I believe and think I said earlier in the thread but I don't know of any cases that would have set the precedent.
