I am using vcuum assist casting with solid flasks with a Kaya Cast machine. I have had some metal
melting into the pads and have had to order a new set. Past discussions include using wet cardboard
under the flask and over the silicon pad. I will try that but would like to purchase or have an extra pad
made. They are fairly expensive (>$25) from Otto Frei. I would like an alternate source and perhaps to
make my own. Ideas?
