Thanks John, it also gave me one hell of a head ache making it. I will do some searching and see if I can find a similar product on this side of the pond.
Tom your right most of the parts are about the same size, the gussets do vary in thickness from one side to the other, the web where the thing splits in half is about a half inch in thickness. the rim is pretty close to the same but the only problem there is being taken care of by the gussets venting the top edge so it will fill ok, I'm wanting to put a core in it just to see if it will work out ok, but that leaves a big problem with the center hub shrinking really bad, there are a couple of things I can do one it to go ahead and put in the core but also put in a couple of risers to feed the thing as it cools and make them open so I can add more hot metal to them to keep them open and hot.
The other is to put in a couple of risers around the rim and let them feed it I have some Exothermic riser cups that when the hot metal fills them they will burn hot enough to melt aluminum so they will also provide plenty of hot molten metal to feed the casting as it cools. damn good thing I got more then two of those cups.
Anyway its going to be a crap shoot either way I go with it, but like they say first time for every thing.
As of this moment every surface is sealed except for the two faces of the plywood that face each other, but a coat of paint will take care of that. would use primer but most of its not waterproof. so yes I can dunk the thing in tub to find out how much metal I will need for it.
Have a Doctor's appointment in the morning, then it will be on to making a flask I figure its needs to be 16 X 20 X 11 deep so each halve is going to be 5.5 inchs deep. THIS IS NOT a ONE MAN POUR
DA
