I finally managed to get some more foamboard in stock. I ordered in a whole extra pack for myself. I got home, excited about getting more work done on the Drake Mk.II. I had one problem, I'd gone and lost my steel ruler! Luckily the one I use at work is my own, so next day I brought it home with me only to find the other one.
Here's the results of that evening's work, I now need to get my compass cutter out to make the turret.
