The discretisation is performed in detail leading to a star-like geometry. In addition, we use the curvature of the disk to obtain the mass scales of this model in a more flexible way. We also discuss some applications of this setup like generating small fermion masses.6 pages, no figures, based on a talk at IRGAC 2006, BarcelonaHigh Energy Physics - TheoryGeneral Relativity and Quantum CosmologyHigh Energy Physics - Phenomenologytext
