  1. Not least the Old London Bridge - not the one that is now in Arizona, but the bridge that stood for 600 plus years with houses; shops; drawbridge and chapel thereupon. The pedestrian entrance to that bridge still stands in Lower Thames Street, opposite Fish Street Hill, EC3. https://www.historic-uk.com/HistoryMagazine/DestinationsUK/Remains-of-the-old-London-Bridge/ And recently: https://tinyurl.com/3vvcps5a
  2. I agree with David Mack. There must be many paintings and engravings that have been made in the past that have been made from memory of a visit to a location. Perhaps when some detail or other is needed, a look though published literature might fill in some required factors, but the end result is a scene which could be many places, but in effect - none, leaving speculation to explode.
  3. Fascinating story of St. Ives bridge and Chapel. Thanks for that link.
  4. Apart from the lovely flight of steps, this is what caught my eye: Company number?
  5. The Troubled over Bridged waters . . . .
  6. Use a team of chainsaws. Sad, but true. £195 for a chance to save a complete engine and Hotchkiss cones. Is the engine and cone configuration worth £195? And then add the cost of transporting away the debris.
  7. I had understood (and I may be wrong) that the tar boats were used to take the waste water products from coking plants to places that could use such tar water for the preservation of wood products, rather than the transportation of fuel or lubricating oils. As to why a pipeline and not boats; Convenience, much like why Motor Spirit stopped being sold in cans, but available from a forecourt pump. The decline in tar boat traffic must also have been affected by the clean air acts which cut back on coal burning in general. Wikipedia has a fairly good article on Coke and the phenolic by-products https://en.wikipedia.org/wiki/Coke_(fuel)
  8. I think I can smell the tar . . . .
  9. A model to be proud of! Well done.
  10. Yes. See Scholar Gypsy's post above.
  11. At a guess, I would consider a 'rigger' hull would be something with out-riggers such as the Polynesian Islanders (and others) would use. Hulls with out-riggers on one side or the other (or both). An imaginative mind might picture such 'out-riggers' to have helped stop Motor Vessel No. 6 from descending beneath the waves . . .
  12. LAPLANDER converted to diesel? Did the owner sell?
  13. Matty49s images are in Berko. Ravens Lane crosses there, and the gable end of the Rising Sun can be seen beyond. The second is taken from the Riser. Flats have replaced the factory that stood there on the offside. I suspect that is VICTORIA. All a bit easy to spot. The less I recall of the 'Nine' the better.
  14. I believe the sprung jaws are to effect a grip on the piston ring so as to prevent its slipping out from the main jaws. Simpler version exist, and do not have such complexities. Good drawings though.
  15. Ken X has it. A piston ring expander. Used for opening out piston rings when fitting them over the piston top. Search for piston ring expander in a search engine, and there will be found many images of different types, from the simple to the complex. Not vital pieces of equipment, but do make the job a little easier. Always used my fingers in conjunction with some feeler gauges to prevent the ends of the rings from marking the piston sides. Needs care and precision.
  16. Nothing makes Bankers blush. It never has in the past, and does not in the present.
  17. Folk law and fable, myths and legends, sorcerers and alchemists - vs - engineers reports and measured elements. The first group requires a degree of belief, the second a reliance on the accuracy of reporting and how it might have been transcribed over the period of time from design and build, to present day. There's room for error, hence certain disgreements. (NOTE: I am not stating I disagree with 154ft, as I do not know between which two points such a measurement was taken. But add 72 ft to 154 gives 226ft, but then there is the length of the longest boat being usable within the chamber with the bottom gate(s) being able to close, and the distance between cill and top gate. Then at what point do we begin to measure from the junction? Lasers at dawn? Not for me. And who or what was Wardle?
  18. Without 'knowing' for certain I would imagine it would be the bottom gates. Top or bottom, why should it matter? It is there, it is acknowledged in stone (by name) and in printed literature. It is part of canal history as being built for the Trent and Mersey to maintain control over the junction, and I'm certainly not going to lose sleep over precisely where it starts or ends. As to whether it's a canal or not, whether historians will debate its length, makes no difference to the fact - it exists as a canal or part of a canal. As to ownership - CRT, for now. With or without lock. As the lock has been called Wardle lock, maybe the 'Wardle canal' incorporates the lock. But then the Middlewich branch could not operate without that lock, and when the top gates are open, the water is part of the Middlewich Branch. When closed, of the Wardle. And who was Wardle? As to being concerned with measurements, I was quoting various claims. Where beneath the bridge do we start from; Face of the bridge? Which side? In the middle? Where the coping stones begin to curve towards? At the centre of the junction mid canal? It can get silly. noun An artificial waterway or artificially improved river used for travel, shipping, or irrigation. A tube, duct, or passageway. One of the faint, hazy markings resembling straight lines on early telescopic images of the surface of Mars.
  19. I wonder if the practice of creating a wooden framework wasn't influenced by the Tudor practice of building with wooden frames. Maybe Brindley thought that, if it worked for houses and halls, it could work for lock building.
  20. The entrance to the Wardle Canal. The first lock is 154ft beyond.
  21. There are only two logical options; 1. Leave it exactly as it is. 2. Take Steve Priest's advice and get it professionally 'cleaned' of old varnish, then coated with artists clear varnish. Its monetary value is only held by the value placed upon it by collectors, and therefore subject to the whims of the market place which can at times be volatile. Its historic value is also subject to opinion. I am certain that those boaters and painters we now revere, would find it astonishing that a simple artefact for containing water could possibly have an accolade attached to it that matches the Holy Grail! Value it by all means, but use common sense.
  22. There was a wonderful YT video that has since been removed (?) showing a Pilot casting off from the bank in a small row boat, and almost casually arriving at the starboard side of a Steam paddle tug within about fifteen feet of the thrashing paddles. He throws a line to a deck hand, who also throws one to him making the row boat fast before climbing aboard and taking his position in the wheelhouse. His departure was almost as nonchalant - pure poetry and skill.
