Basing spaceships

I've been asked how I base my spaceship miniatures.  It's a fairly simple process using wooden disks from a craft store, fender washers, regular wire nails and superglue:

First, I remove the backing from the disk and attach the washer.  Even though the disk has adhesive on it, I still apply super glue, because I've had the assembly come apart when I didn't glue it first.

I hold it together for several seconds, then I drive a nail through it from the bottom.  Note the use of a magazine to prevent holes in my kitchen table:

 

The finished product looks like this:

And here you have it with the mini attached:

Easy and cheap, which is how I like my miniatures gaming.
