Here's a project I did yesterday... An ork bastion "upgrade". My FLGS is doing a planet strike campaign so I didn't want my orks to have to use a plain old human bastion. Everything is magnetized, so the bastion can be "downgraded" back to the original setup. The magnetized pieces are able to stick on nicely with just a magnet on either side of the bastion walls, so even the inside magnets didn't need to be glued. Obviously I could have gone further, but I stopped there because I felt it made for a decent bastion upgrade, and I had limited time.

I made this for an article for [url="http://www.miniwargaming.com/x.php?x=ptgraham&y=http://www.miniwargaming.com/content/hcbHL5PaiShe&c=bols"]miniwargaming.com[/url]. A free login is required to see the full article (with lots of pics and explanation).
