Thanks for the info.....
Looking back at the stamping die you made..... should be able to replicate.
The CMP fuel tank is very light material and may be easier to form...... baffles would be necessary. Based on the many rusted tanks we have worked on the baffles are installed first after the outside skin has been pinched and welded shut.... baffles are then inserted and welded by a long arm spot welder. The reserve baffle is sealed tight on all 3 sides using a rolling wheel welder simialr to what they weld the end caps with. Can't afford all the specialized machinery but our time is free and the challenge worthwhile. We may just spot weld some baffles and then weld the end plugs ...... the soapy test is certaily worthwhile but would be safer with a liquid sealer for the finish process.
May try some scaled down smaller pressing over the Winter months for practical experience....... maybe tackle the small indent for the bottom drain plugs.
Cheers
