  1. That's logical, heavier saw needs more counterbalance
  2. When they fitted mine they replaced the 100A one with a 60A I'd better correct that, the fitter said it was 60A but I just went out and looked at the meter and it's rated at 100A
  3. Did he stop and sharpen it or just carry on?
  4. 15hp on a 240 Volt single phase is only about 50A so easily doable, starting up may need some thinking about. As long as you don't have a smart meter you might even do 30hp if the main fuse will stand 100A.
  5. How on earth do they get to that? Grid is 3 phases 120 degrees between each phase
  6. Having drawn a state pension for 5 years and supplementing it with part time working I'd say the biggest contribution to comfortable living is not having to pay rent, so look on buying a home as part of the plan. I actually only started drawing half of my private pension at 70, and that makes me an income tax payer again. My biggest single unavoidable expense taking up over a quarter of the state pension is rates.
  7. 8mm, 9.5mm or 10mm? Why double fishermans over a figure of eight or bowline?
  8. What rope and length does one need for trying these different knots out on a modern climbing rope?
  9. I have had this and it has been since I was prescribed statins following an incident.
  10. Yes chrome plated aluminium cylinders were common on bikes and I assume saws in the 70s, I just wondered when nikasil bores became common
  11. Me too, I'm all up for replacing a piston and recovering the bore on an antique but once you have to delve into the crankcase... BTW I have never split a chainsaw crankcase other than to see what's inside.
  12. Mahle developed nikasil for car engines in the 70s, do you know when it was first used on saws?
  13. My tractors got changed to historic vehicles without my requesting it, I wonder if they will catch me, last time I got pulled on one was 1980 in Chiselhurst.
  14. I have searched for a number on mine but can only find the body type (C1M) and not the model number but suspect it's C1m-fr1 from googling . I would get parts from L&S or Rowena motors, hugo is very helpful there.
  15. Zama carb kits are expensive so when I had problems with a Still HL75 long reach hedge cutter I bought a non genuine carb for it from L&S. It looks like you need part number 541-60430-03 but it might be worth asking if they have a non genuine carb. BTW my venerable Makita back pack blower is amongst my most reliable bits of kit.

  16. Was, is and always will be as well as a religious bigot and war criminal.
  17. I've mentioned this before but I was always surprised how harsh the fell cut felt when felling ash and douglas whereas beech and hornbeam though harder woods cut more easily.
  18. Just a bit of an update and when I said I averaged 6kWh a day this was a simple calculation from my electricity bills over a year. This method essentially masked how much of the electricity my PV panels produced and I used. Now having had the battery a few months and taking daily readings of the PV meter and the grid meter I see I actually use on average 8.6kWh which is a surprise but for the fact we cook on electric. It does mean that we were probably only utilising about 2.6kWh on average throughout the year from the solar production, most being exported for 3p/kWh. This is a little graphic I produced from my (almost daily) logging of grid use and solar PV production. The gaps show where I missed days and the following column is the total for the missed days and the current day. You will see some days the usage seems to drop down a lot, this is where the battery has stored from the previous day but the solar production has been low. These last several days also don't give a good picture because once the battery is full on a sunny day we have been exporting 2-6kWh/day. I would need another meter between the solar system and grid meter and before my consumer unit and this is not practical without a complete rewire as the consumer unit is shared by the solar/battery system. I intend to heat my water in the summer by solar electric and eliminate use of gas where possible. So the battery has increased my utilisation of solar electricity greatly since mid February. Because of the weird logic of growatt ( the battery has an intermittent fault which requires a reset after it is full and the excess is exported, the fitting firm are being awkward) and that the battery was a retrofit imports from the grid will never be zero. I suspect I should have researched more and gone for another firm's inverter but heh... The economics of the battery; it looks likely from March to October it will save us about 5kWh/day in electricity and some undetermined amount of gas many days in this period, so at current rates about £1.20 plus savings in gas at 8p/kWh. Which will pay off in 10 years at worst, we'll see. I'll continue to monitor for a while but intend to just let the system get on with it. What it flags up is the need to generate 2-6kWh/day in that deep winter period Nov-Mar and that is when the stove is running 16 hours a day. Pointing to the need for a simple themo-electric device. Discuss.
  19. For accuracy I would take a photo of the tree (tag) close up and carry a garmin GPS which I took a photo of the time on its screen at start. At the time my phone or camera had no GPS and the garmin is more accurate anyway. Another advantage of the garmin is it plots my position every second. These photos synchronised with a free bit of software would then load onto google earth or could be plotted onto an OS base map. It was an inventory and simple triage collation rather than a full inspection so the client only required a spreadsheet and the photos to refer to.
  20. A long time since I did this but with a Palax on a tractor I reckoned 14 bags of mixed hardwood, cut ,split and stacked in the barn was a good day for me. Bags loaded on the upside down pallet tines of a small front loader
