I looked for ages for some cast-iron brackets for hanging baskets on the outside of our old workshop, but could only find modern ones or rather expensive reproductions. Then, whilst clearing the loft of our 112 year-old house, I came across an old cast iron Singer sewing machine frame and treadle which had been up there since we moved in nearly 40 years ago. Looking at the treadle, I realised that cutting it in half diagonally would yield two rustic-looking brackets.
Drill and 1/4" drill bit
Step 1: Find a Donor Machine
We had found no use for this old chassis over the last 37 years, so I had no qualms over a bit of constructive vandalism.
Step 2: Check Your Pattern
If you try this, be careful where you cut, since I discovered that to get the pattern I wanted, I had to cut in the centre of some of the 'filligree' sections, effectively sharing the available metal between the two brackets. I found a 1mm thick cutting disc made light work of the job and didn't remove too much material. N.B. Cast iron is quite brittle, so don't apply too much pressure or drop them. (Which, unfortunately, I did during painting, and broke off a small section of one 'hook.')
Step 3: To Paint or Not to Paint
Cast iron is pretty corrosion-resistant, but I decided that a coat of black Hammerite would improve the appearance and prevent any future rust. We are really pleased with the rustic appearance of these brackets that really compliment the old workshop and the minimal cost. An attractive piece of up-cycling, if I do say so myself? I hope you like the idea and that it gives others some inspiration.
