What about using a white foam cooler you can get from Walmart during any
summer. I think they cost about 3 bucks. Fill it with 3 gallons of water,
mark the line... empty water, place release agent ( plastic wrap ) inside
and fill with your plaster up to the given line. Be it would be alot
faster
just a thought.

>I have bee perplexed for som time on how to make a 3-gallon header tank
>but I think I have a solution that uses the pre-molded F/G tank for a mold.
>
>Simply use PVC Foam Bead-Board to fabricate dams in the pre-molded tank in
>accord with the volume desired and line the cavity with saran-wrap for a
>release agent. Then place a piece of plastic pipe in the middle of the
>cavity equally spaced from the foam dams and any side wall of the
>pre-molded tank. In the middle of the volume outside the pipes hang several
>very light chains(optional). Then fill the void contining the chains with
>"Casting Plaster" of "Plaster of Paris". When it is cured then remove the
>pipe in the middle and the plaster cast from the pre-molded tank.
>
>You should now had a form to lay up your header tank on. After your tank
>is cured then wind the chains up that you cast into the plaster on a
>slotted flat bar to break up the plaster form and free your new tank.
>
>I got this idea from the way filament winding forms are made for limited
>production cylindrical tanks.
