Step 1: Materials
- 1/2 inch EMT conduit, available in 10 or 5 foot lengths (also available in 3/4 inch diameter)
- 1/2 inch conduit straps, 2 per window or 3 if it's a big window
- L brackets, 2 per window or 3 if it's a big window
- one small nut and bolt to attach each strap to an L bracket
- two 1/2 inch pieces of 5/8 inch dowel rod
- cheap/used/salvaged kitchen cabinet knobs for the finials
- flat black spray paint
Here is my cost breakdown:
- (10ft.) 1/2 inch EMT conduit = $1.97
- (3) 2.5 inch L brackets = ($0.70*3) = $2.10
- (3) conduit straps = $0.10*3 = $0.30 (pack of 25 - $2.54 / 25 = $0.10 per unit)
- (3) screws and nuts = $0.08*3 = $0.24 (pack of 12 - 0.98 / 12 = $0.08 per unit)
- (2) 1/2 inch stubs of 5/8 inch dowel rod = $0.04*
- (1) can of generic black spray paint = $0.98
- (2) surplus cabinet knobs or other creative object for finials = ???
Total: $5.63, not counting the finials.
I had surplus cabinet knobs from when I replaced them in my kitchen. If you don't have any laying around you should be able to salvage or scavenge some at the usual places: thrift stores, yard sales, auctions, surplus construction material liquidators, or even curbside. If you actually have to buy some new they shouldn't cost much more than a dollar a piece. Of course, a truly Creative Person would create stylish finials from scratch. Maybe someone else can contribute a specific Instructable showing how to make prettier finials... Worked metal finials would be really sweet! Or if you had a lathe handy I suppose you could turn out nice wooden finials.
(*I already had surplus 5/8 inch dowel rod on hand but a new 4 foot dowel rod would only cost $1.98 or about $0.02 per 1/2 inch unit)
Pretty basic: drill, hacksaw, screwdriver, sandpaper
