I don't use foundation, never have, and doubt I ever will - but - I do love a challenge, especially an engineering challenge ...

That is a better version of what i had planned actually.... The mold and frame i was going to try and cast in one go, but the more i think about it the less i like the idea - air bubbles being the main reason.
Looking at the 'professional' molds you can buy for $800US (they are aluminum) as inspiration, just trying to recreate one of them without that sort of price tag really.
If i cast one side of my plastic frame, flip the whole thing then cast the other side, i will have the spacing right as well (yes its a 'plastic mold' space, not a 'wax space', but close enough for this)
I happen to have a can of spray designed to release casts from molds, its designed for latex and such, but worth a try with an epoxy
Unless i suddenly get a bunch of time free its all hypothetical, life has a habit of getting busy lately!
And don't stress Ben Framed - i know the odds of this being a great success are very slim. The odds of it working are reasonable and its just an experiment really, not planning on going into production or making hundred of foundations (go google the machines that do this! they are great fun to watch!!)
Good tips, thank you
