  1. With those rays on the cut face? I was going to say it's a lump off a stag headed oak where the sapwood has rotted and sloughed off.
  2. So is there a 2:1 reduction on the belt drive pulleys? I have never used one. On the tuning; back in the 70s my Husqvarna dealer had a centrifugal fan that was spun by the saw being tested, the load could be altered by varying the inlet to the fan, so it could be loaded to set the rpm. A similar thing could be done with a disc fitted with magnets and copper coils with ballast resistors where the work piece should be.
  3. I've never really learned how to tune a saw or hedgecutter that has a rev limiting coil, it's generally not been a problem as I tend to blip the throttle on the power stroke with the hedge cutter. I used to have a lot of problems with the Stih BT 45 power drills at work, they invariably came back with the exhaust caked in tarry oil where unburnt fuel had passed through when they were constantly held on the limiter.
  4. He said he had retired so he may not look in as much now.
  5. Sounds like one for @adw
  6. Whitelands Sawmill | Sawmill Directory SAWMILLERS.CO.UK Based in the heart of the South Downs National Park – Sawmilling & Timber products – Sawmilling Mobile Sawmilling... There are probably others nearer on the web site
  7. well done, I reckon I break more than 50% of the yolks when I have a fry up 😒.
  8. Definitely, I don't think oak sapwood is good for anything other than firewood.
  9. Dutch ones may have been willow but cloggies working man's ones were alder with segs in the bottom and leather uppers.
  10. Yes I was thinking redwoods would be too soft and lack strength. I get the impression elm is fine if totally submerged or buried, less so if wet and dried. We looked to sell shook oak for groins.
  11. Fine then but Jose was being recommended a Jimny and I was warning that there may be a problem towing an unbraked chipper with it. I'm out.
  12. That's irrelevant a 110/defender weighs 2 tonne unladen so a 750kg unbraked chipper is way under half its weight. The C&U regulation only effects lighter vehicles that weigh under 1500kg unladen when towing an unbraked trailer
  13. It won't be on the plate, it is a construction and use thing.
  14. yes, my vitara can tow 1.2 tonnes with overrun brakes but because you should not tow an unbraked trailer that is more than half the unladen weight of the tow car. So an unbraked chipper of 750kg is too much.
  15. if they are as light as my old vitara they can only manage 500kg unbraked,
  16. Reminds me of when a Welsh student told me how to say "pleased to meet you" in Welsh when I was to be introduced to my Welsh tutor 😉
  17. Yes but it was only the stuff with dimples on one side that exploded. I guess it was steam trapped in the cement.
  18. When I volunteer with the Ramblers on footpaths, under the supervision of the local authority, those using the battery brush cutter have to wear hard plastic shin guards. I thought it was OTT but...
  19. We got given a box at the Albert Hall in about 71, cannot remember much about it but he wasn't bad. His style went more to his roots as he got older. I certainly understand how a rocking boppper wouldn't get excited with his music but for truly depressing Harry Nilsson did it for me.
  20. I bet, who pulled it out?
  21. Why ever not? 15 years ago I spent months with an Ahwi in a 100 hectare plantation taking out the rhody in between the trees with a skid steer. The follow up treatment was good and last year the ecologist told me there was none to be seen.
  22. Shame it wasn't a woman, apparently they can multitask and safely keep their eye on the task as well as the camera.
  23. Who is the person intent on getting the action shot? I guess the customer took the video?
  24. I have never seen one but because it is a boxer engine, each piston moves out at the same time, it should be very well balanced and low vibration. Because the crankcase is shared between each cylinder and the crankcase pressure (as each piston is on the power stroke) still acts as a scavenge pump the saw is not piston ported. So the air intake past the single carburetor is controlled by a reed valve on the crankcase.
