Hello
I am sorry for this old question BUT I am confused as to how the pressure pot used by HWSNBN for his castings both works and is physically constructed and how it operates. I thought one introduces a set pressure into the pot with the rubber molds inside and that forces air bubles to shrink in the mold. However I hear that a vaccum is the way to go to draw out the air bubbles.
Question from what I see in the pictures of HWSNBN`s work shop and his pot. Which is his method and how is the setup made and how is it run? Details PLEASE.
Thanks for your time and help.
