  1. As a former organic chemist I'm the wrong sort of chemist for this discussion. Alloys aren't really my strong point, but looking at the rinse aid ingredients in the sort of rinse aid you are using, I think the problem may simply be that you are not quenching the reaction. The zinc chloride in your Fluxite is continuing to do its thing. Others have suggested use of a weak base to neutralise the acidic fluxite. Sodium carbonate (washing soda) or sodium bicarbonate (baking soda, sodium hydrogencarbonate - not baking powder which is bicarb plus an acid and will fizz rather than do what you want) will do the job as will any alkali-based cleaners. There's nothing that jumps out in your rinse aid to act as a base. I'm not convinced that the compounds you've mentioned are the problem simply because even before dilution they aren't particularly concentrated. Limonene (fragrance etc) and the isothiazolinones (biocides because they are oxidising agents) are prominent on labelling as people tend to get sensitised to them and suffer skin irritation. The surfactants, which are the major constituents of rinse aid, should have no effect on your model. Teaching you to suck eggs but have you tried water only in your ultrasonic bath to see what effect that has as a control? Simon
  2. Copyright law is complicated. If it were true that copyright was irrelevant in the internet age then there would never have been much argument in this case: https://en.m.wikipedia.org/wiki/Monkey_selfie_copyright_dispute Simon
  3. No substitute for appropriate legal advice and/or perusal of the 1911 and 1956 Copyright Acts or CDPA 1988, but this page on the DACS site is a useful introduction: https://www.dacs.org.uk/knowledge-base/factsheets/copyright-in-photographs Simon
  4. B9 1475 appears to be at Brunswick shed Liverpool rather than Neepsend. Simon
  5. Are the sandboxes all the same depth? To put in another way are they all the same height above footplate level? Yours and those fitted to Sir Edward Fraser's tender (see locos of the GCR vol2) superficially seem shallower than those in the models and drawings of Geoff Holt's Imminghams in his Locomotive Modelling Part 2. Thanks, Simon
  6. Happy New Year Steve. I like the BR brake van conversion. I'd thought about doing the same conversion to create one of the unfitted CLC vans. Was shortening the stepboards straightforward and did you consider filling in the door windows in the cabin? Simon
  7. I've gone to such lengths to maintain my load of unfinished projects that I've completely lost one of my unfinished locos. If anyone has any tips on the 4F equivalent of water divining then they'd be gratefully received! Simon
  8. Not quite the answer you require, but try this thread for appropriate numbers to select from: https://www.rmweb.co.uk/community/index.php?/topic/124471-maentwrog-road-modelling-a-real-location/&do=findComment&comment=2945851 Simon
  9. That Old Oak Common variant (I think?) of Intercity livery with the short name really cuts down the options. That and the fact that 1988 was right in the middle of my few years as a spotter so all sorts of silly details stick in my mind from that time as opposed to the important stuff I can never remember! One night a few months later than that photo I was on a train pulled through New Street by 47613 North Star and passed both 47611 Thames and 47612 Titan in the station. Simon
  10. Really helpful to see how you've turned that mix of metal and plasticard into the finished, blended-in structures. Thanks Izzy Simon
  11. The cooling tower and gas holder were both part of Portwood gas works. A feature of Stockport for many years: https://britainfromabove.org.uk/image/eaw002117 Simon
  12. I haven't tried it, but the W irons and wooden solebar options, along with the ability to model double independent brakes suggest it could be used. Unfortunately they are also TOS at the moment. Simon
  13. Hi Justin, The LMS built 5 plank opens to the same basic body style as the d1666 I referred to, but with 10ft wooden underframes. These were built with both 2 shoe Morton brake gear and the double independent type. I know because I started scrabbling round for something appropriate when I realised I'd used the wrong chassis for mine! I don't know off the top of my head whether the LNER 6 planks ever had 10ft wooden underframes or whether the switch to steel occurred at the same time as the increased wheelbase. On checking the LNER did build 10ft wooden underframe 6 plank opens. So 2-513 and 2-535 are options if you modify the brakes where needed. Simon
  14. As 2-330 is out of stock and due to be replaced at some future point, you've the opposite problem to some of us! As David says both mouldings are intended to be 1923 RCH minerals. In practice 2-551 represents a tiny subset of 7 plank minerals due to the shape of the strapping on the wagon sides. The terminology escapes me at the moment, but the style of strapping with a curved transition from diagonal to vertical as represented on the 8 plank was also far more typical on 7 planks. Similarly two piece strapping (without the curved bit) was also very common, but the two pieces of strapping coming together at a point seems from what I've seen to be rare (I haven't investigated the combination of this strapping and steel end stanchions). As a rule of thumb, steel end stanchions were more common on railway company than PO wagons. I've no experience of the NGS mineral, but assume it will need reducing in width as it is designed for a Peco chassis? If some of your underframes can still be built as 17' 6" chassis then do consider some 5- or 6-plank opens. Massively under-represented on most model railways, but extremely common in reality. No layout for the appropriate period should be without an LMS d.1666 open. Simon
