Thanks for the hints. I plan on making some toolboxes and other handy trinkets before having a go on the van. I've managed a few captive nuts and other bits so far. Is the sliding door a good or bad first little project? I guess good for easy access, bad for big flat bit of steel. It is in desperate need of doing and won't lead to a far bigger project. I don't think I'll have loads of time this winter for a full on project, but want to be able to hit the ground running next winter. Anyway I'll stop hijacking your thread and start a new one when I've cleared some space in the garage.
