  1. Foxton. Grrrrrrrrr.

    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
  2. 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
  3. Journey up the Nene

    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
  4. Connecting Digital TV Aerial

    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!
  5. 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
  6. 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
  7. 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
  8. 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
  9. The Boat Behind You.......

    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.
  10. Thanks Tony, that all rather confirms what I was thinking and is very helpful.<creep> I think there is no NRV present on this setup I will see what I can I can do. I do not anticipate this ever being self bleeding. A bit of background, for you; and to help others who may pick up on this thread. This engine was marinised from an ex-ministry unit by a professional vintage engine restorer and there were a few things to sort out. Anyhow it was a good learning experience for me so I won't complain but I guess you can see how I am approaching this. Once sorted the whole setup has proved so ideal I would be tempted to declare it the standard :-) Much of my understanding of all this is based on some lectures by yourself and a couple of relevant CAV instruction books. Interestingly the priming instructions in the instruction book suggest only the filter head should need bleeding and it also shows two arrangements for what it refers to as the back leak connection of the fuel system. I originally moved the filter because the vent was *&%!! difficult to get at and the centre bolt was impossible to remove so the "O"ring could not be replaced at filter change time! This work had the added bonus that the fuel pump itself did not then need bleeding after a filter change. Just like the book says; result! John
  11. I have just relocated the final filter fuel on our Perkins 3152 engine (to make for easier access). Whilst re piping it looks as though it would be possible to send the Back Leak from the pump directly to the fuel tank, along with the spill return, but still keeping the air vent on the filter into spill return pipe. I notice the pipe work on the engine, like most, doesn't follow what would be the ideal route (always rise to an outlet) however the installation is working fine; except ---- sometimes a filter change takes more than just bleeding at the filter head and the pump also needs attention.... I think an easier route for air to clear the fuel system, particularly when doing a filter change, could be arranged but I can find no references as to the ideal arrangement for the back leakage pipe. Does anybody have any ideas or experiences please? John
  12. Cyclists. Sorry..

    We have recently had a couple of visits to Oxford. The courtesy exhibited amongst the users of the tow path was an absolute delight, even after term started,The cyclists pinged a bell, slowed down and gave way to people on the tow path who in turn made room for the riders in a friendly manner. Many dogs were walking the towpath with their humans and even when they gathered in groups it was a calm and civilised situation with every body allowing for each other. We did notice Pedestrian Priority notices every so often along the path but there didn't seem to be to be any need for rancorous "assertion of my rights" Come along peeps is this an answer?
  13. Qube holding tanks

    I have just been trying deal with Thetford about our leaking toilet (see thread about leakage of Qube) even they don't have them as spares. You may well have to do as we did last September and buy two complete units. The whole toilet was as cheap as a spare tank for our original older model We bought two new units as the old 356 we had been using for some 12yrs had started to leak on the bellows and, as is the way of plastics used like this,the the units themselves were getting a little tired. At present I am wishing we had kept the old ones going
  14. Leakage problems with Thetford 365

    I made contact with Thetford this morning and sent the good lady at customer services pictures of the two tanks. She emailed back to say they were indeed faulty and would need replacing. But most apologetically advised me it would take three weeks to get replacements to me, they have to get them from Holland apparently !!! And where would we be in three weeks time for them to be delivered to us. Well 3 weeks and with a toilet leaking fluids down the side.... Any good suggestions??
  15. Last September after many years of good service our Thetford 365 was leaking on the bellows pump and beginning to look a bit tired, So with the cost of the spares taken into account we decided to go with our original plan and just replace the whole thing when it got badly worn. We hoped the new Qube was going to be a good replacement---- As of now I'm not so sure! Up until now we wondered if had been condensation or not properly engaging the parts when changing tanks as we have found water leaking down the side of the base and on other occasions the slide handle seemed rather damp,But yesterday it was much worse.... As far as I can tell the spigot on the bowl is not properly sealing into the holding tank and on closer examination the top deck of the unit seems to have about 1/4" of sag which is putting the connection between the tanks out of kilter. I tried to contact Thetford but discovered, when I called, they close reception on Friday afternoons. This gives me rather too much time to consider what we really want to do about it. ;-) Have we got a faulty couple of tanks or is there a design problem along with the other issues that we have noticed. We would like to hear if anyone else come across problems with this product or can suggest a better replacement. John
