Hi everyone,
I had a look for an answer to this question using the search function but couldn’t find the answer so maybe I just couldn’t find the best words to describe what i want to know.
Anyway the question is, If I want to shape a board that is 18 1/2 wide and 2 1/2 thick do I have to slightly overshape it to allow for the thickness of the glass and resin? and if so, by how much? would 18 3/8 and 2 3/8 give me the dimensions that I am aiming for when the board is finished?
