    I guess im going to go with it as is for now, if it doesnt work out then ill just fill in the void and make some mods to my core box later on. I use petrobond sand so Im going to cross my fingers and hope.

    I may be missing something here but why dont you make the core print a lot smaller, It dosnt have to be the same size as the hole you are creating.

    Donk, I was thinking about down sizing it a bit, but it would be easier to widen it up to the flange and make the core bigger if it doesnt work out like this.

    Well I glued them on, then took a long look at it.... Well i decided to fill it all the way up to the flange. LOL man what a pain, I should have just made them in wax and investment cast them.

    Oh and thank you for the compliment on the patterns

    Oh no no no... what if there is some unforeseen problem that you have to modify the other patterns for?

    Yes... clearly... you should cast...

    Just in case
