Decided that I needed a door to help keep the heat in given the barrel design. Really lucked out by finding a metal works in the village that knocked me up the basic shape out of a bit of off-cut for free, which was amazing. A bit smaller than I would've liked, but beggars can't be choosers! I picked up some handles, a bbq oven thermometer and black stove paint for under £20 and am really happy with the results.
