This is the all-star core pattern, where the ribs and stringers go all the way to the edge. No separate rail pieces.

IT'S DIFFICULT TO GET A SMOOTH GLASS JOB ON THE RAILS with the all-star pattern, using my current techniques. But if you have an idea on how to make it easier, order this kit, try it out, and tell me if it works.

The all-star pattern has a few advantages over the radial-rail pattern. If someone figures a good simple way to get smooth rails, I'll offer more kits with this core pattern option.
