As it happens, I am at the base mounting stage of my Potemkin, so I thought I'd share a few photos of the steps that work for me.
Here's my temporary base that I use for all of my ships. Well, not CV-8 Hornet- she is mounted to a 3' long 1 x 10 melamine shelf.
But you see that the base has as many pairs of hole as I've had to set for the numerous 1/350 ships I've built so far. This base is great because it allows me to handle the ship without touching it too much. One of the other modelers here has a 90 degree end on his and I can see how that would help too.

Here's the Potemkins hull with the finish coat of oxide, and the two 10-32 screws I keyholed, glued and puttied in. I''ve masked the threaded areas where I need them clean later.
These neat little barrels are from the lamp part section at Ace. I have a big bag of them as I like uniformity in my displays.i295.photobucket.com/.../DSCN3384.jpg
Here's the underside of the temporary base with nuts attached in the countersunk holes.
After it's all done, I transfer the ship to a finished oak base. Same kind of set up.
That's how I usually display my ships.
