Al brase >> Al, You're right about an empty gas tank having a fondness for going KA-BOOM! Some thoughts: If it were a shallow dent over a large area, air pressure might work, but without shrinking the metal once the dent is popped, it will tin can, i.e., just pop in and out with any pressure changes. Being that it is a corner dingo, you might want to try hydrostatic pressure. At least 100 psi is available from almost any city water tap, so you would be off to a good start and the explosion potential becomes moot. This base pressure could then be increased by almost any amount using a manual hydraulic pump. But you better have that tank properly caged or have a long hose tagged onto your pump. The real problem with this approach is suitably sealing off all the penetrations in the tank. Perhaps Dentbusters or some other such paintless dent repair operation has the non-sparking tooling and the experience to pop out these dents. George |
