I may try to make an alloy tank that will sit under a fibreglass cover

I wondered if it was possible to create a wooden buck out of slices of ply, and laminate them together, creating a solid wooden buck
I would then hammer the life out of a sheet of alli to form the outside and get a welder to fit the resulting parts together

I have also seen the videos where a skeletal buck is made with ribs and the parts worked on a sandbag and trial fitted

Am I daft in thinking that hammering a sheet over a solid form is workable?

ca, us
Hammering over a male form requires shrinking. A female form requires stretching which is easier. One technique is to use a Delrin plastic ball on an air hammer to push the sheet into the form. There are videos showing this.
If you are not concerned about volume you can make a crude tank from several single curved sheets since you are covering it with glass anyway.
