    No, I understand and thanks for paraphrasing him. Hopefully the next issue will include my article that explains the subject on more detail. One small historical item included that I found interesting was that the first known use of small arsenic additions to control dezincification was in the...

    Well done Vyv Cox - PBO No. 718

    This is a common issue with a certain surveyor. Every adverse comment of his about DZR is accompanied by photographs of zinc plated valves. DZR is never plated, his comments relate to 60/40 brass. These constant errors have been pointed out many times to the editors of PBO and YM, by me and...

    Total gibberish. 1. What does manganese have to do with it? Neither bronze, brass nor DZR contain it. 2. Arsenic forms a solid solution in copper alloys. Any could safely be licked. 3. Blakes are DZR. They do not corrode. 4. We know exactly what is beneath the shiny layer (chromium). It is...

    Conwy fairway buoy

    It was always difficult to find. Quite small and often in choppy water. Not been in the area for many years so cannot comment on current appearance.

    I read it, along with many other magazines, on Readly. Unfortunately there seems to be a delay between publication of the paper version and the digital. Still waiting to see the response to my letter from the originator of the nonsense.

    Calor gas system. 4.5kg bottles.

    My motorhome has a bulkhead regulator that will take either butane or propane. We generally use Autogas, whose composition varies enormously, from 100% propane in UK to mostly butane with some propane in parts of Europe, 50/50 in others.

    Best screws for galvanised rowlocks?

    Exactly. Galvanised screws and bolts available nowadays from vast numbers of outlets are not produced by immersion in molten zinc, they are electroplated. Their finish is bright, so they look better, but the zinc thickness is very small indeed and alloying with the steel substrate does not take...

    Another anchor question 😀

    If they were in intimate contact that might be the case but there is very poor electrical contact between chain links.

    Another anchor question 😀

    I have been using two of these, one on the Rocna, the other on the Fortress, for more than 20 years. This photograph taken in 2007 is the originator of my three chain links idea, now used worldwide. The Wichard shackle was not new then and is still in use. After 5 years or so the galvanising...

    Cutting a boom with a chop saw?

    That is why I suggested in a previous post that the correct way to do it is to mark the line first, then follow it with the hacksaw, not attempt to get through with a single cut. It takes years of practice to make a square single cut, whereas anybody can make the blade follow a line.

    A more comprehensive article is in the pipeline for publication.

    Cutting a boom with a chop saw?

    A hacksaw is the perfect tool. Use a fine blade, 24 tpi perhaps. Mark the cutting line all around the extrusion, then cut along it. Do not try to cut right through with a single cut. Keep rotating the boom, cut following the marked line.

    Another anchor question 😀

    Flat anchors such as Danforth, Fortress, etc hold very well in thin mud, as the tests carried out by Fortress a few years ago illustrated so vividly. They do have the reputation of not resetting after windshifts but many owners would dispute this. Having carried Deltas for many years all over...

    Thank you very much. The latest edition has yet to arrive on Readly so I did not know those articles had been published.
