I imagine your grandfather's ring is made from gold. If this is the case, then you shouldn't have a problem melting the gold down and creating a new band. You might run into some issues with platinum, titanium, or tungsten, but these are relatively new jewelery metals and my guess is that your grandfather had a more traditional ring.
I would recommend that you the ring to your local jewelers (not retailer, a jeweler where they make their jewelry) and have them examine the band. They will be able to tell you if there is enough gold to create a new band, or if you will have to mix in new gold to strengthen it. They will also be able to tell you the quality of the gold (it may be poor quality) and, being experts, will be able to offer you a variety of different options.
Best of luck!
