Ponthir28 Posted November 2, 2021 Share Posted November 2, 2021 There a always a smell in old fishing harbours, sometimes not very pleasant at low tide. Not as nice as bread and cheese. Yes I can almost hear the seagulls. 3 1 1 Link to post Share on other sites More sharing options...

Once you do that, you know that the fishing fleet has gone for good. The details here are so natural and well observed, I keep spotting something else every time look at it.

In Glasgow maybe. In Edinburgh it was "a gnat's ba' hair", which is a slightly different pronunciation. 1 3 Link to post Share on other sites More sharing options...
RMweb Premium Dragonboy Posted November 2, 2021 RMweb Premium Share Posted November 2, 2021 Kevin has planned his structures well to omit the chippy as last time I was at the coast I remember they were a flapping nuisance. Must be where Hitchcock got the idea from. 1 2 Link to post Share on other sites More sharing options...

cliff park Posted November 2, 2021 Share Posted November 2, 2021 May I just tell the story (almost certainly apocryphal ) of the young man whose father was the village wheelwright and carpenter. The young man was drafted into the army and became an engineer. Home on leave he was explaining to his father how they made parts accurate to within 5 thousandths of an inch !!! His dad calmly replies "when I make something, I make it exact" 3 12 Link to post Share on other sites More sharing options...
MrWolf Posted November 2, 2021 Share Posted November 2, 2021 I'm in the middle of rebuilding a 500cc BSA engine, the clearance between the crankshaft and the leaded bronze bearing on the timing side has to be 1.5 thousandth of an inch, or half a human hair, just enough room for a constant film of oil at 60 psi. It was a case of polish up the crankshaft first then machine the tolerance into the bronze once it was pressed tight into the crank case, so no + tolerance. That was fun, given that the bronzes are £33 a time and take an hour to fit, with no margin for error. 5 1 Link to post Share on other sites More sharing options...

RMweb Gold Limpley Stoker Posted November 2, 2021 RMweb Gold Share Posted November 2, 2021 Lovely harbour scene with randomly placed paraphernalia just missing the fishy salty aroma!! By the way, I remember a German colleague saying - ‘it fits like an *rse on a bucket’ (though not necessarily about engineering) 1 1 5 Link to post Share on other sites More sharing options...
Popular Post KNP Posted November 2, 2021 Author Popular Post Share Posted November 2, 2021 (edited) Thank you for your recent kind comments, especially about how 'busy' it is, more pictures will be following confirming this. However, I have been 'busy' and work has started on the former 7768 to convert it to 7750 without top feed. A first pass has been made and to highlight any issues that need addressing I have painted the areas worked in grey primer as this makes things easier to see. More fettling, filing and sanding needed. This time I have tried this with the handrails left on and it seems to have worked. I will not forget the sandbox lids so don't get worried!!!
