  1. Meteor is still unconverted and will hopefully remain that way
  2. it has the wrong carburettor and oil tank too. Tom
  3. The Erewash joins the Cromford end on below the lock at Langley Mill. Tom

    Kelvin K2

    my experience with seaward is that you can drive up there with a pocket full of cash and still come away with nothing, I have some spares for the K and J but no castings unfortunately, I do have a box of bits to drop off with Phil Robins with a cylinder in it. I have some new piston ring sets for the earlier pistons and .030 U/S Main bearings How bad are your current cylinders? I have welded some Kelvin cylinders for both the poppet valve engines and my F4 in my boat. Tom
  5. I have known a BMC to run away, it had about 8 litres of oil in the sump plus whatever it had burnt and expelled from the engine! unusually, there was no diesel in the oil in this engine. I have seen a few air cooled listers of various types with lots of diesel in the oil. Tom
  6. surely if there are so many spring tides at the moment, why hasn't anyone turned right at sharpness and come back upstream and over the weir? not exactly trapped if the tides are high enough to overtop the weirs. Tom
  7. The exhaust manifold is from a lighthouse engine, there is something odd about the inlet manifold, extra holes in the top of it. Tom
  8. I had a tubeless tyre deflate rapidly on the front of my Orange, I now run an inner tube in the front and tubeless for the rear, with a puncture in an inner tube you at least have a bit of time to stop before it deflates completely, with a tubeless setup you are usually going OTB,

    a short video of the engine running on two cylinders

    Kelvin F4 rebuild

    The round flanged piece is a hub from a large fan, it just happens to be about the right size to fit the mounting. I have quite a few of them. I am keeping a magneto as a spare but they are not the most reliable of things. With this system I will be able to have multiple sparks for each firing stroke but still retain the manual ignition timing control the whole system will have cost less than a magneto ht coil rewind!

    Kelvin F4 rebuild

    Sorry for the long delay since the last update, today I started on the electronic ignition system to replace the magneto, this will use a trigger wheel and a sensor and bolts in place of the magneto. Just awaiting the the arrival of some bearings and can then assemble and fit to the engine. Tom

    K2 on ebay

    Already seen that one, same problems though with salt water corrosion, I am looking at fabricating a block, just to see if it would work Tom
  13. Has the boat been overplated?

    Trivia question

    some of the diesels had no provision for mounting the gearchange on the gearbox, this looks like it is just the cover for one of those. Tom
  15. but that would not have been anything to worry about for the GUCCCo as london would not have been full of fat boats tied up for miles with people living on them as an alternative to housing, and any boats would have been tied up properly. I believe the main reason for the slightly smaller blade is that they were always towing. Tom
  16. 24 x 17 sounds about right looking at the ex national blade that was fitted to Banstead when we got her, the GU boats were all towing a butty which does affect the size of the blade slightly, they would also have not followed the modern practice of overpropping to make a nice sound for hours of running at low speeds. it would be interesting to see how the original blade works with a loaded pair, if you can find enough water!

    Kelvin F4 rebuild

    Progress has been slow over the last couple of months, but the engine is roughly in position in the boat, next step is aligning it with the shaft then I will start on the fuel tanks and plumbing
  18. I am interested, not sure when I'd be able to collect as work is getting in the eway for the next couple of weekends
  19. I have done one on an F but that doesn’t really help much. that K was smoking quite a lot, a good thrash on a river might help it Tom
  20. That depends on how it is held in gear, is the boat Frodsham? Tom
  21. Hi Mike, the bearing arrangement on the diesels is different, they have a bearing housing bolted to the crankcase containing the bearing, it just depends what is fitted to the end of the crank, is it a marine engine or a lighthouse engine? I have a pair of 13/15HP poppet valve cranks, one marine and one land engine the two cranks are significantly different but I'm not sure the K's followed suit Tom
  22. The petrol paraffin engines use a ball thrust bearing, the diesels use a large deep groove ball bearing in a housing behind the ahead clutch, this is quite an expensive bearing compared to the rest of the gearbox bearings. the first photo shows the thrust bearing, the second shows the ahead clutch fitted. the diesels use a different bearing. hope this helps Tom
  23. How about reopening frodsham lock? that would be a nice alternative route Tom

    J2 Exhaust system

    Here are photos of a few Kelvin silencers, early J type Ricardo type from an F4 Globe silencer for 3 1/2" poppet valve from 1915 onwards and the early poppet valve type pre 1915 this one one is also for a 3 1/2" bore engine Tom

    Kelvin F4 rebuild

    They are rubber O rings as I have left the correct springs on the boat. They are working for testing though Tom
