Kind of an odd place for the info to be, but...
Damage dice increase as follows: 1d2, 1d3, 1d4, 1d6, 1d8, 2d6, 3d6, 4d6, 6d6, 8d6, 12d6.
A weapon or attack that deals 1d10 points of damage increases as follows: 1d10, 2d8, 3d8, 4d8, 6d8, 8d8, 12d8.
If you're wanting weapons to do more than 12d6 or 12d8 damage...well...just follow the pattern of doubling from the previous entry (ie, 1d2x2=1d4, 1d3x2=1d6, 1d6x2=2d6, 1d4x2=1d8).
Hope that helps.
