  1. one issue i do have was the front side screen windows, they sit on an angled base, but they slide forward just slightly, so a solution was needed, so a small part was created to give a section of a lip to stop the side screens slipping forward, nothing much was needed, just something to catch the bottom of the frame, so using a scrap of teak, i created a part to make that lip.
  2. with a bit of time on my hands this morning its some more woodwork, using another piece of the burmese teak, i have created a pattern in thin ply, then transferred to teak for the folding parts of the cockpit sides, i have pieses of the teak cut into various sizes and thicknesses, for the hinged pieces the sides are a bit thin, so i will be backing the hinges fixing points to thicken up the wood i can fix the hinges to. i have a selection of hinges, these are literally the smallest hinges you can buy, yet are still a bit big, but the smallest piano hinge available is huge in comparison (all shown in this picture).
  3. the worst bit was that i made the edges of the roofs deeper than i needed to, so have had to notch out those sides for the window hoppers, getting it so the roof still fitted was fun (especially the front roof that slides forward into position), the front of the notches had to be angled to accept this, but all sorted now.
  4. a quiet day today, so as i had a busy day yesterday i decided to potter on with the model, window hopper production line day, of course they are different sizes and even one frame is different one end to other, so a gauge was used to ensure the angle is the same.
  5. John, considering he has found the seized big end bearing, i sort of assume the sump is already off (especially as it was needed on the replacement engine)
  6. does that mean a new crankshaft is needed or can that one be reground to repair it?
  7. so was it a blocked oil way that caused the problem, this leading to the big end seizing? or low pump pressure, or just lack of oil?
  8. this is why i replaced the half width spare on my v70 with the full size one from my older v70, sure i lose some boot space and the liner that goes above the half sized spare, but since i do over 30,000 miles a year, i consider a full size spare as an essential, i cant be having being stuck due to a flat tyre, I also carry 2 air pumps (so i can lend one out to a colleague if needed and still have one to hand for emergencies.)
  9. so glad all our office staff who normally work in london were in brentwood for our team brief today, sad for those that have suffered.
  10. sorry about this, we are all volunteers and sometimes life gets in the way of us doing our jobs here, and the mailbox only goes to one of my computers, I can probably reset your password for you (once I get on the right computer)
  11. but that doesnt have any ie's or ei's in it
  12. MM all energy (from whatever source) is just fed into the national grid. What happens when you pay for 'Green' energy is that you are paying one of the suppliers that feed green energy into the grid (from a wind farm etc) what you get is a dollop of energy that could have come from any source through the country, what you get could have been input into the system from a diesel generator or coal, or anything, you are buying green energy because you are paying the company that added green energy into the system (think about all those thousands of people who believe that they are getting the energy produced from the wind turbines directly, all those nuclear protesters that are happy that their particular energy doesnt come from nuclear plants) its all fed into the same wires, and is identical to any other package of energy that flows out the other end, so when they quote percentages its spread over the whole national grid. if you really want to know how much energy is currently being derived from which type of supply, then have fun looking here http://www.gridwatch.templar.co.uk/ for instance we are currently (as a nation) using 43.58GW of electricity, nearly equal amounts are being generated by the cleanest and dirtiest methods (wind and coal) at just over 5% nuclear is running about 17% and 47% is gas turbines, biomass produces about 7% and solar about 8%, a further 8% is being imported from France holland and belgium (ooh I wonder how that will work after Brexit) so how much of that counts as green energy then? to make up your 30% nuclear is being counted as green - low emmission) as while it is running it is very low carbon emmission (as long as you dont count the building and decommissioning of that nuclear plant), of course we arent just importing foreign energy, we are also exporting it to Ireland (thinks if we imported energy from ireland would that be green energy?) so about 2% of our energy is being sent abroad
  13. I agree MM, particulates are the bad boy with diesel engines, but on the broads the exhaust systems are generally wet exhausts, so the sooty smoke is mixed with water, which should generally remove some of the particulates from the atmosphere and theoretically disperse them in the water, now whether this is in any way better than kicking them out into the air then having them settle onto the water i have no idea. But and this is a big but, compare the number of engines on the broads, to say the centre of london, the broads may spread several thousand engines over its 120 mile extents, car and lorry engines are all clustered in one place (usually for me the dartford tunnel or QE2 bridge (150,000 vehicles a day)) and there will be tens of thousands of them daily spewing out the particulates in a fairly small area, the two dont compare.even when you have 30 boats in a small area all starting up simultaneously, it doesnt compare to the number of cars and lorries starting up at say the services on a motorway on an hour by hour basis, the pollution caused by boats as opposed to cars or lorries is infinitesamal in the great scheme of things. at one time the major concern was the lead from petrol - we introduced unleaded petrol then it was carbon monoxide from petrol, so catalytic convertors were added, with diesel it is particulates, so now we have particulate filters being added to cars and lorries (i believe the adblue is something to do with this too. some diesel fuels emit more than others too, with vegetable oil diesel being a slightly cleaner option than fossil fuel diesel. the biggest part of the pollution that occurs is through cars and lorries only being driven for short distances and constant stop starting with engines not properly reaching operating temperature. I do a 125 mile daily commute, I do it in a diesel car, and the car gets up to full operating temperature quite quickly and stays there, my car is 17 years old and sails through the emissions part of the MOT time after time as it runs at its optimal temperature, I have seen 3 year old cars fail the emissions test due to never having been driven more than a few miles a day, and that all in heavy traffic so mostly on tickover. the solution is better local public transport, if people could manage without using their car locally then pollution would be less and a lot of the carbon targets would suddenly become easier to achieve.
  14. unfortunately (weather permitting) I am busy tonight so my apologies to all
  15. actually when you look at it converting electricity from for example wind generators to hydrogen is a way of storing that energy for when its needed, besides there are already chemical processes that give off hydrogen as waste.
  16. and I guess for some weyford bridge is a bit of a problem too
  17. All very fine if like me you hire or own a boat that can go the right side of the bridge, but for the majority who cannot pass Potter heigham, a lot of that dredging is a bit of a moot point as they cannot enjoy it (I am certainly hoping to spend a day or so exploring those locations in may when I am around the broads next.) I suspect the access issue is why there are not more congratulatory messages, so here we go, thanks Broads Authority from my point of view anyway
  18. never been able to get that right, maybe I am ie dyslexic
  19. or maybe its a fuse, here are some suggested replacements (not)
  20. especially at the prices they charge , one example to recieve an email- they can charge £13 to send one out £26, shocking
  21. probably replacing all the old gas meters with modern smart ones in the process if they have any sense.
  22. no pictures just yet, but the other rear windows have now recieved their hoppers and glass, work slowly progresses in the background, more often than I post updates, because one evening may just be 10 minutes cutting out the side frames for the next set of hoppers, and then followed a day later by the caps and spacers, a third day may be cutting the crystal cases to size and then fitting on a fourth day, then of course I dont always get anything done every day, so while progress is ongoing it isnt always at a point where photographs show a great deal happening
