  1. Newbie concerns

    I have a reactive rescue GSD, who initially hated all other dogs but loves people and children. 2 years of training and socialisation, incliding daily pack walks for the last 6 months, has brought him to the stage where he is OK with other dogs when off the lead, unless they attack him, in which case he tend to over react and goes for the kill. However the pack walks are helping with this. On the lead, and since I have been taking him on daily walks along the towpath, he can now walk past about 50% of approaching dogs (up from 0% at the beginning of the year) without incident, but still barks and/or lunges at the other 50%. I now use a Trixie loop muzzle when he is likely to be in the presence of other dogs, as it allows him to breathe but not bite (although he can nip with it, good for self defence). https://www.trixie.de/heimtierbedarf/en/shop/Dog/OnTour/Safety/Muzzle+Loop+Nylon/?card=22894 As others have suggested, it is best to try to get your dog socialised as much as possible. It is hard work and takes a long time, but is worth it in the end.
  2. I don't use anything in mine, but it is a macerator, so never actually open to the tank.
  3. I don't know, possibly because they want to recover the development costs of lithium first? Perhaps, having seen the success of the using industry in selling vinyl, cassette, cd, dat and then vinyl again to music lovers, they envisage something similar with batteries? Cynical moi? I witnessed a practical demonstration of aluminium air batteries as a one shot alternative to standby generators back in the early 1980's, the only obstacle being reducing the production costs and persuading customers to buy them.
  4. Box or rail

    Mine are like this too. I think it is the safest option. I once saw someone slip from the gunwales on a boat with tubular rails. He broke his arm on the edge of the cabin roof.
  5. In terms of energy density (watts per kg), nothing can touch the aluminium air battery. It is easy to produce commercially too. The major stumbling block is that it is a primary cell, so can't be recharged. However is is almost 100% recyclable, so just needs a network of battery replacement stations to make it viable, particularly to power electric cars.

  7. trailer with surge brakes

    Very possibly, I had no experience of towing until that, indeed my first experience was with towing the generator with zero nose weight! The Land Rover has a height adjustable hitch and that made a difference to stability too. It was most stable when set to the natural height of the towbar on the trailer ( a twin close coupled axle jobbie).
  8. Only if they live to tell the tale
  9. what oil

    We used Morris Golden Film 20W50 in the Turkish built BMC 1.8 in our last shareboat. http://www.morrislubricantsonline.co.uk/golden-film-sae-20w-50-classic-motor-oil.html It got to 13,500 hours before needing replacement with a Beta 43.
  10. Wood veneer.

    Yes, I'm really impressed with Le Tonk. I tried it on some wooden patio furniture last year, as a precursor to doing the external woodwork on DQ. it is easy to put on, (although needs lots of coats for external woodwork), gives a good finish and looks great. Hopefully it will meet the hype for longevity.
  11. Bit difficult if they are sealed cells though.
  12. Day time Tv

    It's all due to the "raspberry jam" effect. I first heard of this about 30 years ago when I attended a conference on the future of the telecommunications industry. There was an American speaker, who said that the number of TV channels would dramatically increase in Europe, as it had in the states, and that telephone companies would have to offer TV over phone lines or go out of business. He said when The UK only had ITV and BBC for 12 hours a day, only 24 hours of TV programming was needed. The USA then had 25 channels, showing 24 hours a day, so 600 hours of TV programming was needed. The problem is that there are a finite number of people capable of producing high quality TV so the number of hours of quality TV is fixed , so the more channels there are, the more thinly the quality TV becomes. This is the raspberry jam effect. The UK now has over 300 free to air channels, plus at least as many subscription ones, so the chances of finding quality TV is getting smaller and smaller.
  13. Yes, let's hope they don't take as long to production is as fuel cells. They have been on the verge of becoming cheaply and widely available for 45 years now! Lithium ion batteries have been around in iPods and phones for for about 20 years now, and whilst the cost per watt hour has come down a fair bit, it still has a long way to go to match lead acid batteries.
  14. trailer with surge brakes

    Definately not the case for the mobile generators I tested. When I hired Bruntingthorpe Vehicle Test Facilty to test the stability of the 3500kg mobile generators, we moved from absolute balance (no nose weight at all, to 150kg nose weight (the maximum recommended for the Land Rover Defender tow vehicle) over several steps. The rig circulated their track at a steady 50mph, whilst being overtaken by a 44 tonne artic at 56mpg, a 7.5 tonner circulating at 70mph and several people testing racing cars at very high speeds. Each increment of increased nose weight improved stability and reduced "snaking time". The trailer designer said 4% was the theoretical ideal nose weight, (140kg for a 3500kg trailer) and we couldn't go over 150kg, so unable to test the impact of too much nose weight.
  15. I agree the volts and Ah in/out seem to correlate. Have you synchronised your BMV when the batteries are fully charged? If you don't do this regularly the % charge will get progressively further out of kilter. Also have you got the correct settings in the BMV regarding battery type, capacity and when to stop charging? It is particularly important to change the stop charging % F3. The BMV default is 4% tail current, and a more realistic setting is 1%. This thread shows my learning curve on the BMV. Since then I have reduced F1 to 400 Ah to reflect the reduced capacity of the 10 year old batteries (measured by discharging to load at theg 10 hour rate) and further decreased F3 to 1% which more accurately reflects a fully charged battery. To synchronise the BMV when you are sure the batteries are fully charged, simply press the left and right arrows together for 3 seconds, with the display showing the % SoC.
