Looking good so far.
You're at this point after just 3 nights?
I got this same kit on my workbench at the moment. It has been in progress for about three years now...
(well, most of that time it has spent in the box, as I temporary lost interest after finding out I needed a different type of gun mantlet)
You have an interesting way of mounting the inner wheel halves first (or are the glued on yet?) I think most builders would leave off the whole wheels to paint them separetely.
