Barbara is right, it was Ruth Niles that I got them from. They aren't as bright and shiny as the chrome, and to be honest the brass and titanium black ones are very nice also. BUT- down the line if the SS holds up like they say it will it will be great. I have just about used all the SS ones so I need to order some. I bought the ones without threads and have used 5-min epoxy to hold on the wood, so far it has worked great. IMHO avoid using CA to do this, it won't hold up.
I find bottle stoppers to be a nice diversion from bowls and such. They are fairly quick and easy, but still have a lot of areas for creativity. I have sold a bunch also but it has to be the right show or market. I make a lot of cheap ones with nice wood and corks, and then use my best wood and other enhancements on the metal ones. I used to buy a lot of cabachons to glue on the ends but lately I have been fusing dichroic glass cabachons myself.
If you really want to see some nice bottle stoppers search Yahoo Groups for the Bottle Stopper Group. I lurk around there some and have seen some very nice stoppers that go way beyond my imagination. 😉
Here is some of the new dichroic glass cabachons next to a bottle stopper with a jasper cabechon, plain chrome instead of SS, and a scrap of burl I picked up somewhere.
