Not really a tutorial but maybe helpful.....
First I turned a pattern and cast it(and a spare) in delft clay....
Then I cleaned up the casting ,drilled and threaded it and made the stopper.
Then out of 18 gauge silver I made the lower moldings after making a brass pattern to my drawing.
Then I silver soldered the two best moldings to form a cone
Then I silver soldered everything together and finally nailed onto the wood flask.
Hope this helps !!!
