  1. The driveline vibration was in fact a banging noise like rattling a half brick in a bucket :-) it didn't shake the boat just stopped us engaging gears at low engine speeds; so we had to wind the speed back down after putting into gear at higher revs. We have separate speed wheel and gear change so not impossible in practice but a pain that got fixed as soon as we got onto the canal system! The Tico is a good idea and I have used it successfully for higher frequency noise on heavy machine tools -- I did get some pads ready for when we were getting the engine setup and running, but, I never got round to trying them out. It might be a good idea also to check that the engine sits evenly on all four feet; try rocking it on the diagonals to check. I should mention this is a traditional engine room with a universal joint propshaft under the back cabin floor.
  2. Our boat has a D3.152 which is mounted onto 4" x 3"(approx) oak bearers which in turn are bolted onto the engine beds. The engine beds are something like 10 x 5 angles running along the engine room. This set up has been fine for us from tick over at 500rpm to 1400rpm which takes us to 7mph on the river. When we first saw and tried the engine in the workshop before we purchased it it was standing on a fairly lightweight cradle and it seemed smooth enough through the range. We had a problem with drive line vibration when we got onto the canals but once we got the drive plate sorted all has been OK.
  3. Try this I hope it helps... Most systems use a masthead amplifier near to the aerial which is powered by DC on the aerial feeder (which in effect then both carries power and signal; the signal is separated, by capacitors,from the power). Now at some point the DC voltage for the amplifier has to be regulated, usually this is on the amplifier at the masthead but with the Moonraker the DC is regulated on the DC injector( power supply) rather than the amplifier. ( I have checked this to be so with Moonraker technical.) What you refer to as a "booster box" is I THINK in fact the power supply; so DC goes up the feeder and the connection to the TV just carries the signal which has been amplified at the masthead. In your case I wonder if there is some issue with the power connection. For background:: We originally had a masthead amp powered by a DC injector which we then connected to either a Yagi(log periodic) or a little stub antennae depending on signal strength. When we tried out the Moonraker I realised (and checked) the power supply was different and fitted an additional feeder setup. This has worked as well or better than the original aerials which are still stored away, not used now since the new setup!
  4. We have been using a Moonraker for a few years and it has performed remarkably well; from Great Ouse area up to Ripon and across the Pennines. We even got some useful signals in places where an amplified aerial had not worked previously. A couple of points: The voltage regulator for the amp is in the Moonraker DC injector module, UNLIKE normal aerial amps (so DON'T try connecting it on an aerial feed with DC on it! ) It is useful to raise the aerial on a mast and rotate it (check for polarisation on a relay) if reception is poor But generally it just works.
  5. Steel pigeon/dog boxes don't have to be the cause of condensation problems if built the right way. I was concerned about condensation from the roof lights when we had our hull built but Roger said there would be no problems the way he would make ours-- He was absolutely right. Our roof lights are fitted over an up stand on the roof of the cabin and the lids have lips which turn down,this arrangement causes any drips to end up outside the boat. The clearance gaps and slot vents also provide the basic minimum of high level ventilation needed for the cabin and because they are quite long there is less of a draft than a normal mushroom vent. Our boat has only portholes but the usual comment from people visiting is "how light it is inside" and as previously noted there is rarely a good view out of the side when tied up. (some ones cabin side or a dogs bum on the towpath ;-)
  6. Just a thought, but might this be a similar issue to one of our dogs being absolutey scared of going near or traveling in our car.( so how would we get to the boat?) He would always leave the house and pull over to the other side of the garden furthest away from the car whenever we went out for a walk. It 's sorted out now and he travels fine any where car, boat or train..... It was in someways the weirdest thing we have had to deal with in all our rescued dogs, but really the most rewarding. The approach known as "systematic desensitisation"; is to subject the patient(dog) is to increasing periods of the stressor for periods shorter than that which would take it to be upset. {Its a completely benign technique, rather than the Woodhouse "flooding method" and is supposed to be longer lasting!} Right. I'll try to explain the practicalities. We first just sat in the car, in a closed garden, with the doors open and read the paper/ had a cup of coffee so the dog could wander around suit himself, eventually he became comfortable getting into the car.... Then the interesting bit comes we had to gradually increase the time we ran the the engine/ moved the car; but by amounts so small that he didn't notice and on NO ACCOUNT LET HIM GET DISTURBED. In this case we could only manage increases of 30seconds each time or so but GRADUALLY to get to half an hour; at which point the issue was resolved!!! --- I don't know why the turning point is reckoned as half an hour but that is the "magic" time. I hope that makes sense, please ask if I can help more, I have cut the details rather short keep the post manageable. I do hope you can get your pet happy on the boat . John
  7. How can volunteers without expertise be allowed the to dictate how we use the fatalities we have paid for ???? We too were somewhat peeved when Kathy was told that the locks were closed when she inquired at 2:45. A bit later on as I went down to sort out rubbish etc. I discovered the Volockies bringing a boat up the flight I did ask if we could come down and pass in the middle (as we have done on previous occasions) but this was refused. Chatting later I discovered the volly had no interest in boating or boaters needs but was there because he enjoyed the power and needed something to do since retiring! Now we build our boats,pay large sums of money to be able to use the waterways and its locks and in doing so provide entertainment to the non-boating visitors. Should there be a category of volunteer boater ;-) John & Kathy
  8. Just been told this lock now has an early closure. ---- people have had to turn back. Sneaked onto CRT site. We, and several are others, are having to return south :-( John and Kathy
  9. We have just done your planned route and came onto the G.U. and moored near the junction this afternoon. Everything has gone quite smoothly and the Rothersthope locks were, unusually, all adequately in water. 3 3/4 hours without trying.( We have been through a few times though and know how to use a bike to set the locks optimally for the low pounds). I imagine our staging of the journey will be different from yours but Please ask if we can help with a specific question. John & Kathy
  10. We are using one of the Moonraker aerials at the moment. It certainly seems a bit better in locations where we have previously struggled to get an entertainment signal, the old setup was a Yagi with an amplifier, though indeed on many occasions a small mag mount stub has been adequate on that amplifier. We have only been trying it out for the last week so I can't give a full report as yet.... A WARNING I should point out the majority of head amplifiers use 12v sent up the lead , the moonraker power inserter/adaptor has a regulator to provide 5v for the aerial lead ---- don't mix the two systems. It will cause problems!
  11. So----- Having at, last!, got fittings made and installed, discovered the back leak on pump outlet was a NRV . I piped every thing up to the theory. to avoid air traps. Here goes; turned fuel on ----Opened vents on agglomerator and filter pumped the primer and closed the vents as the fuel flowed out. What next! all the pipes had been changed and empty, should I, I wondered do some bleeding at the pump? Give it a try! wound speed wheel open, pressed start and away it ran as sweet as could be RESULT. Never had it work like that before ..... Thank for advice and encouragment John
  12. Further investigations reveal the NRV is in the right direction for flow out of the filter head. I have no sense of what was intended.... (as a side point, only relevant to access issues though, I am starting to suspect the exhaust manifold has been fitted the wrong way round!) Anyhow I think I can re-pipe this lot sensibly and indeed so that the back leak doesn't drain back. The problem now is getting fittings with the right thread " You always used to get them at the Lucas depot!" But I have a plan and access to a lathe ----- I'll report on my efforts. Best regards John
  13. I think that is very probable. The pipework indeed seemed rather odd. The connection to the pump from the final filter swept round "in an air trapping loop" it could easilly have had a better route from the other outlet on the filter head. I guess you can see why I am doing this work on the engine! In fact this filter head was the agglomerator when we got the engine, made redundant because I had fitted chassis mount agglomerator and sedimentor before the engine. ( Now where did I get that idea from ? :-) I also understand that these cyclone type devices don't work as they should when vibrated mounted on engines.... I shall test your suggestions next. Thanks John
  14. Thanks, I know what you mean. There is in fact such a valve its in the out feed to the thermostart device (bonfire plug) though in fact that seems to be non-functional and fortunately not needed :-) John
  15. Interesting, We had some character of a similar nature follow us out of Braunston tunnel the other year. I had gone ahead to take over from the people leaving the lock and as their boats were leaving I watched this boat try to pull into the side. He executed a "superb cock up" with the boat going all over the place. I was rather worried at that point about how we would would get down the locks together. BUT NO he held back and would not come with us. Later Kathy told me he had, in fact, tried to sideswipe us into the shrubbery, presumably out of his way. It didn't work however! our boat is deep and heavy... He then played the same tricks with the lock paddles as you describe, no worry to us and we soon left him to play on his own. He passed us much later after we had tied up and I was doing the chimney brasses. Earlier in the day we went up the Buckby Locks with a nice couple with a smallish boat and they were still shaken up from a similar sideswiping incident with a fuel boat------ |This boater?,when asked said he took exception too their notice about speeding boats and had done it on purpose. I'll leave that story for your judgment.
