I am now going fishing Henry. I will be using a Cordell CC Shad Green/Yellow to see if I can snag a lake trout

This pic is only a few days old

The hit was real.
The fight with 4lb pound line was real.
The landing and pics are real.

Are you sure that trout is not fake, there are a lot around...

Meanwhile this from my last visit to the deep south (latitude 46 degrees), no dover sole there, but enough kai moana to keep the whanau replete. One of several.....
Fishing for the Iwi
Savoured whilst listening to Schuberts Trout Quintet - Schiff/Hagen Quartet on Decca.
Well seasoned & accompanied by Rudi Bauer's excellent Quartz Reef Central Otago Pinot Gris.

Halcro - steamed with ginger and shallots.

Sounds delicious Henry.

The authentic Canadian recipe is a shore lunch and it includes a small fire next to the water, beer mixed with specially seasoned flour in a pan.

Nice fish Dover. sounds like a great time was had by all.

Dover - Are you sure that trout is not fake, there are a lot around...

I now await to hear about your next adventure Dover - We have heard many mystical stories here about the great white's downunder.

Have you ever fished for
one?

I agree we do need to be careful of fake fish.

Is it time for some clothes.....👀👗❓
Five years ago I went nude...but don't tell my kids...
Three years ago I went nuder...kind of 'Punk Mad Max'....
Sound was good. Inspired some fellow converts and adherents but a small problem arose.
Whilst my solid cast bronze armpods at 25lbs each would never move......the rather lightweight cradle could often be nudged in the process of cartridge swapping and the spikes could slide along the hard laminate on the cantilevered wall shelf..😩
Tired of re-checking the alignments of three arms, I decided to drill through the laminate at the positions of the three spikes to prevent any further sliding.
Mission accomplished but small problem now became BIG problem..💀
The tips of the spikes now made contact with the shelf substrate and its inherent stresses. These subsonic tensile stresses now induced a resonant frequency response in the stainless steel cradle which transferred to the platter/record interface and could be amplified by the stationary stylus at maximum volume settings.

Most turntable designs deal with structure-borne feedback in a combination of various methods with mixed results.
Suspending the plinth on springs or trying to isolate it with rubber or other compliant feet or various types of air-inflated supports is one method.
Mass is another. Real mass is still another...
I have chosen to try a 'mass' solution...🐘
The idea behind the 'mass' approach is the hope that physical vibrations can be absorbed and dissipated as heat within the plinth/platter instead of allowing resonant response characteristics.
Sometimes this works and sometimes not....
With the space restrictions of my 'nude' setup I can only create a cylinder of either granite or gunmetal/bronze (wood is simply not massive enough in this small structure).
Bronze would weigh 3 times more than granite (19Kg vs 7Kg) but also costs 3 times more...💲
So at this time....somewhere in China, there is a CNC machine routing and polishing my turntable 'plinth' cylinder out of a solid block of black granite..😊
Gosh I hope it works.....

Hi Henry, Did you consider slate, or is it difficult to source slate in Oz? I suppose bronze is even denser than slate, but I think slate competes with granite, for density. This is not to say that I have any way of knowing whether slate is better than granite for this application.

Hi Lew,
As I'm only concerned about density, slate and granite are pretty similar but granite is more homogeneous as slate is riven. So, it's far easier to know what you will get with granite...👍
Also getting polished pure black as a visual finish with granite is simply not possible with slate...
