I take exception to posts that are clearly copied and pasted from some non-attributed source, particularly when they are only vaguely relevant to the discussion. Rigging screws are made from tin bronze, in some cases possibly phosphor bronze, the same composition but with a small addition of phosphorus as a deoxidant. When researching my book I was not able to discover whether some manufacturers were using silicon bronze or aluminium bronze (although I doubt it) so I added those words to the website as a catch-all.
And here we go again .
Jimmy Green sell three lines of bronze turnbuckle: Petersen, Stalok and Hamma. Petersen say they use aluminium bronze; neither Stalok nor Hamma say what alloy they use.
The Petersen website confirms this claim, and also says "Old fashioned turnbuckle bodies are manufactured by forging a soft bronze to produce the desired shape.", confirming by implication that aluminum bronze is not the traditional material. It may be significant that Stalok say "Forged from high tensile Bronze alloy"
Same thing. Baseline sell Hasselfors rigging screws and Hasselfors is part of the Seldén group, having been taken over in 1989. The Seldén website confirms your claim: "By making the body of the rigging screw in chrome plated aluminium bronze and the terminals in high grade marine stainless steel..."
Vyv said that aluminium bronze may be used. It is, by two manufacturers, one of whom has recently introduced it. All the others I can find say just "bronze", from which the most that can be concluded is that they use the traditional alloy for that purpose.
It is. I recommend it. A lifetime of professional experience beats ten minutes on Google any day.
a few arabs and a speed boat
are you suggesting the Holly Loch ,,, not bad idea .
I suggest you re-read your post, upon which you will perhaps see why I said it was irrelevant. It has nothing to do with rigging screws, largely being about galvanic corrosion in various alloys. A good deal of it concerns nickel-aluminium bronze and duplex stainless steels, from which rigging screws to my knowledge are not constructed. It is difficult to know just what the article is about as you have not linked it to the original but it would appear to be more about propeller materials than rigging screws, but certainly to items intended for underwater use.
Two manufacturers appear to use aluminium bronze, and one of them only started doing so recently. Perhaps neither did when Vyv wrote his book. An any case, your aggressive rudeness hugely diminishes the import of anything you have to say.
sure is lovely stuff , neat weldingAhem!
Now all I need is a suitable boat.....
Since non of this involved you but you seem intent on continuing it even though there isnt more to say, then ?!
It involved me, as it involved everyone else who reads it, when you chose to make public attacks on Vyv.
