Jay,
We I was working, We built tanks that held explosives for the mines (5000 gallons at a time) these were double walled with insulation between the walls to keep the tanks warm for more bang :twisted: . Could you take your small model and use 10/12ga material (I'm not sure what your currently using) and put some sort of insulation in the middle of the walls to help with the cost and weight issues?
