Well, yesterday I took the boy out for his very first trip to a hardware store so mom could have a bit of a rest, and we did some searching. I found zero stainless steel wool (found some regular steel wool, which I didn't buy) but I did find: 1. a nice long flexible water hose thing for a SS braid and 2. a scrubby that is supposedly composed entirely of stainless steel ribbon. It doesn't look like the scrubbies from the US - this looks like a big ball of 0.2 cm wide SS ribbon that's pretty darn thin. I'm thinking it would work well. I suppose the best test is just to leave it in a bucket of water and see what happens?
As for the braid, thanks to Denny's instructions, it was super easy. Fits in there real nice, and seems to draw off liquid no problem. All this new equipment makes me want to do a test brew with something super basic, though, because I don't want to use my specialty yeasties for anything that might taste bad. Probably do a basic SMASH with some old hops just to get the system checked out.
