I have the drawings and have made the tooling to make the 1903 spare parts containers. The big issue is the scrap rate of the containers. The striker hole is the most difficult. It is drilled at an angle and the original build utilized a single three step drill bit. To have the original drill bit made is outrageous as far as cost. So I did the setup and drilling of the striker hole in three steps. This is where the problem is. The walls of the container are thin and the torque of the drill bits crushes the walls if it is slightly off line when drilling. I would start off with about 75 walnut containers and after drilling and routing I would end up with about 23 to 29 containers. I am still looking into getting a bit made.
