Scaratch built 32" ESB Millennium Falcon

[JAWS]

Ok so got home went for a walk with the kiddy's & got straight into it. I really have no idea if this will work. I saw Sean C a very good modeller doing something similar with the foam though was a different product etc. the method is sort of the same so my mind is telling me this will work Ive sprayed between all the ribs with the filling foam & it looks pretty bad right now. the plan is to come back when its cured & hopefully a box cutting blade will cut through the top along the ribs giveing me a roughly filled in dome shape. I will then come over that with the Poly Potty to fill in all the areas the foam didn't & give it a coate. After that has set I will sand it all down to the ribs & will then hopefully have a full shape which should be the plug for the Falcon Domes to get vaccuformed
