[Lord of Angmar]

What i meant was, not, "could memake another ring of power", but could he make rings like those that ensnared the Nazgul?

I already addressed this in my first post:

First of all, after he created the One, he was revealed as Sauron to the peoples of Middle-earth, so no one would henceforth be willing to accept a Ring of Power from him if he offered.

He could have created more Rings after he created the One Ring, but no one would have accepted them. If you are asking if he could have done this before the creation of the One Ring, then the answer is yes, he probably could have created more, but what would be the point?
