  1. probably at the bottom of the river at the end of a rope - being washed
  2. to the forum Sundog, and thanks for your post
  3. I have a water tank on mine (in the airing cupboard) and next to it is a red bottle thing, the gauge is on the bottle thing. there should be a section of removable pipe next to the bottle thing, you connect this up and turn the taps on each end to pressure up the system. the systems tend to lose pressure if you bleed the radiators. the last time I had a problem with my central heating it was the tap on this system, the rubber valve came away inside the tap and stopped me shutting it off
  4. you should try getting hold of one at christmas - my central heating has only ever broken down on christmas day - and its happened 3 times now (though its been a few years since the last.
  5. I see one on gumtree for £45, sadly I cant post a link from work.
  6. talking of repairing, sadly nowadays parts are not designed for repair, I recently managed to get a canon camera cheap at a boot fair, when I got it home I tested it to find it dead as a dodo. google told me that in all probability the fault was either a faulty sensor switch on one of the doors, or a fuse had blown, after eliminating the faulty switch I stripped the camera down and bridged the fuse - in this instance the fuse was mounted on the circuit board, and was less than 1/16" (1.6mm) square, definitely not a replaceable fuse.
  7. on my last (petrol) volvo the CO emissions actually measured at the last MOT were way low (about 1% of the allowed emissions, ) but that said the car was in daily use doing 120 miles per day, so the engine ran clean as it got to temperature and stayed there for an hour or so. I am looking forward to seeing the results of the emissions test on my diesel volvo when it comes up soon as that is doing a similar run daily. the biggest problems with high emissions from cars is the lazy just pop down the road, drive round town mentality of the drivers, where the car doesnt get run up to temperature properly, and runs dirty.
  8. the other option is to make up a metal bracket for the base of the antenna, and make sure the bracket is earthed to the boat earth, you could probably mount a metal plate on the top of the new mast for the antenna, nipped between the mast and the nav light on top, extended just past the wooden top knob with the antenna mounted on the plate (once again earth the plate)
  9. in the CB radio days this was a common problem that had to be resolved when running a cb antenna on a fibreglass bodied vehicle, the common practice was to either put a steel plate under the body panel to act as the ground plane, or create one with a smaller plate and lateral wires, which the earth connection of the coax was attached to, this should resolve the reception issues. failing that just run an earth wire down to the main earth from that bolt, this in itself will act as a ground plane for the antenna
  10. So today being a nice day, it was time to get into the workshop and process the windscreen further. Time to fit the hinges to the side pieces. hinges positioned, drilled through at 0.7mm, the hinge part opened out to 0.8mm, stainless steel pins fitted through and glued in place, finished product I am happy with.
  11. I already feel alienated by the latest thing which is where you dont own your car - you lease it, but once you get above about 15,000 miles a year the cost becomes prohibitive, so I guess its car ownership for me until I retire.
  12. I'd like to see one of those doing my daily 120 mile round trip commute for the price it costs me at the moment, electric is out of the question as I could only just manage if there was a charging point at work (which there isnt) and as we are in an industrial estate in the middle of nowhere we arent even close to a town that might have one.
  13. to be fair everything on the broads front is quiet at the moment, so the non broads topics thrive, they have always been there, but during the season are generally swamped by the number of broads related posts.
  14. i did notice the charity thing was slipped in almost as the last paragraph, as if in the hope that nobody reads right to the end properly
  15. I seem to recall it was one of those pay as you go bikes he found abandoned at brundall
  16. we apply diversity to projects (the assumption that everyone isnt using everything at the same time), your average house uses 1.5kVA (kW) if it is gas heated, if you add electric heating that figure rises to approximately 6kVA, thus you need at least 4 times as many substations and larger cables etc etc, add car charging to each plot (3kW) and that now 6 times as much electrical infrastructure required
  17. this was the only line that worried me.
  18. if they have found someone to run the shop at acle, and refurbished some of the moorings and taken control of the toilet block, does that mean that have abandoned their short term plans for the visitor centre on the site?
  19. if its the latest broads Briefing there is a link from this page http://www.broads-authority.gov.uk/news/broads-briefing-march-2019
  20. JM, if your original came in as an email you would need to copy and paste the text of it to show it here. if the email linked to a page you would need the URL of the page.
  21. go on griff, show him a picture of your work van.
  22. the question is if the demand for electricity to the homes is going to be met. we also do fibre installs, I recently had to quote a fibre duct run in rural sussex, as the nearest BT fibre was over a mile away the quote came out in 6 figures
  23. you will never get the infrastructure to provide the additional energy for the charging points, especially using the existing cabling in most large towns and cities. to provide the additional cabling required throughout a city like london would mean ripping out and completely replacing the existing infrastructure. at present our cable routes to supply new buildings in london are getting longer, up to 6km from the outskirts to provide enough energy for some of the new developments, since a fast car charger on average uses 3x the energy needed for a house, we dont have that sort of capacity to spare in our capital. No, the answer is the development of hydrogen fuel cells, that is the only way we will manage to bring in electric vehicles - but then where will that hydrogen come from?- water, well the infrastructure for that will have to be upgraded, electricity will be needed to crack the water into oxygen and hydrogen, and that takes energy. if the government were serious about this tand started upgrading the infrastructure to cope with all this the next problem would be - where do we put that infrastructure - the pavements are already full, laying new services in the carriageway isnt the ideal solution, but thats about all thats left to us - so what does that mean, yes to improve the infrastructure roads would have to be closed so the work could be done, oh that means the cars wont be able to drive down them - catch 22 anyone.
