It took about 30 mins between starting and lighting, so well worth the effort once materials are collected. The best part of it was the first 10 mins (drinking a litre of Jack Daniels).
This is my first attempt at an instructable (and I've just downed a litre of JD to make this project possible), so give me a break!
Step 1: Collect parts
The Citronella and wick had to be ordered as it's not the stuff I tend to have on shelves. A one litre bottle seemed ideal as I was going to empty into a one litre JD bottle. The wick was ordered as one meter. Both of these were found quickly on Ebay.
