Training Tinkering - How did you GM it with how many ingots?

[Pringles]

I started my character with 50 tinkering. When I started training I used power hour and kept on going untill I was GM.

This is what I made and the number of ingots I used:
50-90 made lockpicks and used 5655 ingots
90-GM made heating stands and used 12747 ingots

Total ingots used: 18402 ingots.
