    To be pedantic (before anyone else is), you only need the fundamental and the odd harmonics! Chris G (who still occasionally uses Fourier Transforms)
  3. If the 4.5" refers to the OD of the pipe, then these people (and many other industrial pipe & fitting suppliers) have them: https://www.valvestubesfittings.com/welding-pipe-fittings/butt-weld-fittings-bs1965-en10253/en-10253-butt-weld-45-degree-elbows-long-radius They will be in carbon steel (or stainless, if you are feeling affluent), so ensure that you have a suitable weld procedure for welding the elbow to the pipe! Chris G ETA Confusion may be caused because many pipe fittings are specified by the Nominal Bore of the pipe, not its OD.
  4. 45 degree butt weld elbows to ASME 16.9 / BS 1640 are also standard pipe fittings. Chris G
  5. Agreed - although I think that the pub could have been saved if it had changed direction over the past 5 years. However, who in their right mind would want to live there, with the West Coast Main Line on an embankment 10 metres away on one side, the narrow, well-used towpath directly outside your windows and boats running their engines moored up outside? Sounds perfect! Chris G
  6. Living less than 100 yards from the Crystal Palace, I have heard this story many times, but have never seen anything to substantiate it. I suspect that it was only the original facade that resembled the Crystal Palace (apologies for the tiny image):
  7. Here is the planning application: https://planning.dacorum.gov.uk/publicaccess/applicationDetails.do?activeTab=summary&keyVal=QEOJCXFOJYL00 Chris G ETA The Viability Report makes interesting reading. Savills would probably taken a different view if they were trying to sell it as a going concern!

    Starter current

    As an electrical engineer, it was the data that I found beautiful, not just the colours! Chris G

    Starter current

    A beautiful graph!

    Starter current

    The Bosch BNG starter motor which was fitted to my Bolinder 1052 was rated (from what I can remember) at 2.2kW when running and the locked rotor (starting ) current was given as 600-700 Amps with a terminal voltage of 7 Volts. When I did some test using a large battery bank and very thick cables, my ammeter went of the end of the 1,000 Amp scale on starting! Chris G

  12. Foam board, which is available in a range of thicknesses (mine was about 5 mm), doesn't rot and can be wiped clean. Chris G
  13. I have found that a Brushmate works brilliantly. However, the saving in white spirit is more than offset by the need to buy a large number of Purdy brushes to make the best use of it! When I was fitting out our boats, I probably 5 or 6 types/colours of paint on the go at any one time, then factor in a couple of different size brushes for each paint and the number of brushes you need is rather horrifying. Basically, I only cleaned them very occasionally, or when I ran out. My record for storage in a Brushmate is about 5 years, when I forgot that I had left some brushes inside it. They bristles were still soft and they cleaned up perfectly.
