  1. Some "man flu" then, best wishes for a complete recovery.
  2. The nut head isn't deep enough to get a good grip so I used an angle grinder to cut out 3 apertures to get a better purchase on the clutch of 254 and 262 (both of which I still use)
  3. It may only be a blocked pick up in the oil tank or even a rat's turd like piece of gunk in one of the plastic lines. I've only had a pump give trouble when a piece of balertwine got jammed in the clutch and stripped the nylon worm gear. Clutch can be difficult to get off if it hasn't been off for a while. I favour a piece of starter cord in the spark plug hole AFTER the piston has covered the ports and then a light tap with a modified socket clockwise.
  4. 15kW is about 20bhp. The thing is the tractor is only optimised at about 70% of rated power whereas the 3ph is is pretty good from hi idle to full power at the same speed. I expect the average power of the electric motor will be around 5kW so it will use about 40kWh per day, say £5. The tractor will use about £16 in fuel alone because it is sitting at hi idle between saw cuts.
  5. I found anything bigger than the 4000 just pulled the County backwards. Also bear in mind anything up to the 1184 was only safe to tug 4.5 tonnes of traction. We did have an 8000H on a 974 but the electro hydraulics played up and were converted to hydraulic only. For static pulls the Farmi 8 tonne was better as it acted as its own ground anchor. Be aware also if you add front weight and it still rears up you can crush the bell housing, this is one of the reasons the highland bear had the branch deflectors in tension.
  6. Diesel at best 40% conversion thermal energy to motion and costs ~7p/kWh, electricity ~90% conversion electricity to motion and costs ~12p/kWh but motor has a fraction of the maintenance costs. In practice when using a 10 kW diesel to generate electricity we averaged only 20% conversion. My guess would be a kWh at the shaft will cost between 17.5p and 35p for gasoil fuel and about 13.5p for 3ph electricity.
  7. I agree to send it away to have it re tensioned and gulleted but touching up the top face only with a flat file is necessary between major sharpening.
  8. NO because you may only think you want to ONLY do physical work all your life. Looking back on my life with few qualifications I'd advise get a college qualification and then aim for continued professional development as you work. Many entrepreneurial types will profit with no qualifications, those of us with little commercial flair are probably better off being employed and qualifications are a means by which an employer gauges your initial worth.
  9. Yes, decent qualifications come in handy if you want to venture into management.
  10. What are the pros and cons of having the wedge moving on the piston rod compared with the piston rod pushing the wood through the wedge?
  11. If the developer has the agreement then the council have to do the maintenance but any liability must remain with the owner I think. Unless no one ventures onto the space the council cannot establish exclusive use and the agreement to maintain would prevent them gaining possession as this would be seen as a licence.
  12. Some of the tropical woods, those known as mahogany possibly, deposit grains of silica (sand) as they dry and it comes out of solution. This makes them too abrasive to mill when dry so they are only milled from green.
  13. I can vouch for one attempting to bore into a douglas resin soaked thigh whilst driving a ford 4000 with tongs. The ovipositor doesn't have a sting but a stinger is a modified ovipositor.
  14. NO. Fair enough to borrow (and credit card is a bad way to borrow) if you are guaranteed the work with higher pay to pay it back but never invest on an offchance. Any decent firm will pay for training but expect to have to pay it back one way or another.
  15. Yes Dave bought some of mine when he returned and got on this wagon.
  16. I didn't mean it was the best option but up till 30 years ago English sawmills wouldn't pay much for chestnut ( because of shake??) and then a couple of firms realised there was a demand from Portugal. The interesting thing was that the Portuguese would mill short logs and butt joint random widths for things like drawer bottoms. Also around this period I started noticing pub table tops in chestnut. We were able to sell sc coppice that had gone over rotation length and all the time the bark remained smooth there didn't see to be any shake even on sandy ground and the Portuguese would by sawlogs at 8"qg where British mills would not accept butts less than 12 or 15 "qg.
  17. That's a significant size, 22 Quarter Girth, if they are sound and clean they'll go for export.
  18. Both the person felling and the person causing the felling
  19. We sold scots for woodwool (Thermacoust) in 1978 at £19/tonne roadside to Forest Thinnings (Euroforest predecessor). I think cut and extract was £8 then. I think that was the peak period for softwood and continued in decline, especially after 1991.
  20. I thought the MK was just the 4wd version, it carried on production longer because of military orders.
  21. Looks like the button for the flashing beacon on my truck (aftermarket fitment)
  22. Lucky for us old uns that's not the way it happens, I'd be below the minimum wage if I was paid on climbing performance.
  23. I find the Google mapping app with traffic is a good indicator of congestion on my android, I think this is crowd sourced data. Presumably the tom tom one uses traffic cameras and the loops in the road?
