Tell us about yourself!
I followed your plans (most of the way) and made one of these bad boys at the weekend. For the spark arrestor I picked up a cheap metal bird feed (GBP 3 from Robert Dyas) and also a sieve from poundland (cut the metal mesh out of the sieve and rolled it so I could stuff inside the larger mesh of the bird feeder). The bird feed came with a handy rain cover so sorted. Looking forward to using the stove for real.
