New to game, Painting advice and fix for Bismarck Turrets?

Thanks much for the advice and the welcome! I'll definitely look into the washers idea. Does the washer allow the turret to continue rotating, or would you need some magnets or something to make that work?

I came across some great instructions already for the Tirpitz, so when I have the time and energy I might give that a go. So far I've just been directly applying some shade and highlights without primer, just as a quick touch-up. It won't last, but it looks pretty good for the time being.

I've another question as well: I've been looking into acquiring some Japanese cruisers and battleships from Shapeways, as thay have much better dimensions than the actual WotC models I've seen so far (looking at you, Haguro). Problem is, I don't have cards for a lot of these, and it's a bit expensive to throw out 50 bucks on Ebay to get a card with a model I don't really care to use. Any ideas on where to acquire cards?

I know Forumini has custom cards, but what other options might there be, to your knowledge, beyond Ebay and Forumini?

Thanks again, and happy to join the community! I only wish I had known about this game years ago
