Removable Mortar and Pestle help needed Answered
I would like to make an Alchemy Table (before I lose your attention please lemme explain) that has a removable Mortar and Pestle in the center.
I am planning either to have a removable M&P or have one just built in (carved). I would prefer the first option. I have thought of just creating a hole with a slight bevel to keep it secure but I need help on how to know how big to make the hole.
If I can't get that done and need to make it built in then I would like to know how to make it structurally stable so it doesn't collapse under heavy grinding.
(side note on the alchemy part: I am only an Alchemical Apprentice so I'm not ready to transmute anything yet. I'm only interested in it for medicinal purposes. This is going to be a summer project so I have some time to make sure I understand the principles or the practice.)
