I want to build a liquor shelf similar to this:
I've seen metal piping and flanges like this at my local big box store, and it usually comes in two flavors: galvanized steel or black iron pipe.
The problem with the black iron pipe though is that its always coated in some type of grease, which would obviously be problematic for us in furniture such as what I want to build.
So I ask: what type of black metal could I use for this, where could I find it, and does it come with fittings (such as the elbow joints and the flanges) that I could use to reproduce this liquor shelf? Also, any suggestions about attaching it to the wall?
