Kyr,
You are correct. After the players have started I charge 2/3 price if they make it. But for starting equipment I allow 1/3 cost. Simply put, its items they made during their inital training to get the ranks. (I only allow this if they have 4 ranks in the skill.)
It all boils down to DM call. I think its worth giving the players a little extra to start with. Until I made that rule no one wanted to get crafting skills. Now its more of a fun side item in the game.

That doesn't really make sense. You don't have a forge, because you have the smith skill, any more than you have a ship because you have ranks in profession sailor.
The cost for materials in crafting weapons is pretty well laid out in the PHB - but as a reference if you wanted to make it easy and say 1/3 the item cost for materials 1/3 for renting the forge, resulting in a savings of 1/3.
If the character wants to know why, opportunity cost for the smith he is renting from not be able to work on his own stuff, cost of fuel for the forge, staff to bring fuel, water, pump belows etc. Rent of the actually space the smith himself has to pay for that period.
