Hi John.
Thanks for that, different place but those kids look a lot like the kids of my village.

As regards ship building does anyone know if they still build ships from the keel upwards from as near possible in the N and S direction. Which meant the slipway was in this direction. The purpose of this was to infuse the least magnetic deviation into the ship as possible. The earths magnetic field running between the magnetic poles runs mainly in this direction and as the final product of the ships deviation was mostly caused by all the hammering and working of the steel it was found this was the best way to build ships.

When I was building my tin boats and launching them into the river I didn't look to see which way they were facing, I just hoped they didn't sink with me in them. But on saying that I never knew that they launched them that way for that reason, another thing learned off this site, thanks

Des Variation and a deviation and compass adjusting are a subject on their own. John in Oz is lucky enough to have a mate who makes his living at, so to a certain extent could baffle most of us with science . Basically theoretically seamen are taught to correct their own compasses when they reach a certain rank and are examined to do so on what is called a Deviascope in an examination room ashore. Although have done myself would prefer to employ a qualified Compass Adjustor. Your Lord Kelvins Balls and Flinders bars and a myriad of bar magnets inside the binnacle are all arranged to do this. In my estimation they earn their money. Cheers JS

Ship building has begun again in Adelaide ship yard.
Frigates for Australian navy, no mention of which way the keel will lay tough.

#6 Probably not , maybe not required today with all the choice of materials re shipbuilding for warships . The likes of minehunters have little or no steal in them in any case. Alaminium is a dubious one as during the Falklands war it was found to burn too easily. During the last war the degaussing fitted to merchant shipping was found adequate for protection against the magnetic mine .;Some may remember how this equipment was tested when running , was by placing a lifeboat compass on top of the casing protecting the cable and watching the card swing 180 degrees , reversing the polarity of the ship. Just wondered if anyone knew of the old building techniques formerly adhered to . Cheers JS

If they use Spanish steel like they did with the trams in Sydney they will face down

Just noticed have spelt steel wrong ,just shows must be getting old so maybe best to make apologies for future mistakes in advance. Maybe Spanish Fly may be more appreciated ? Cheers JS
