I showed the (almost) complete loco in yesterday's post, last night I finished editing up a video of how I built it, so if you're interested please do take a look. It's exactly the sort of project I needed - a lot of what I've done lately has been fiddly to set up, or used expensive parts, or just taken a long time to do, this one was refreshingly simple and quick, probably done in under an hour if you don't count painting time.
