(for the grunge people...its fancy, it's victorian, ...just deal with it).
Step 1: Materials and stuff
Nothing in this tutorial is essential, feel free to experiment. I did. Go raid the thrift stores for all the brass you can find.
brass stuff (chandelier, lamp, candlestick, bucket, towel rack supports, coathook, screws, nuts, bolts)
1/4" wooden doweling
gorilla glue or equivalent
spraypaint (gold, copper)
jigsaw or equivalent
screwdrivers,hammer, needle nose pliers, metal file, vice grips, punch (+ random regular tools to suit)
old phonebook or large chunk of wood
Step 2: Paint the banister gold/brass
I made several of these and the non-oak ones look best because there is no grain, a softwood is smoother.
Step 3: Supports for the boiler
They have a plate on the bottom of them to affix to the wall invisibly, and then the support goes on held by a tiny set-screw. I sort of came up with what the whole structure would be sitting and marked the spots and mounted the plates.
