The bathroom cabinet I am building has 7 adjustable (with shelf pins)
5/16" glass shelves.The sides and back are painted birch plywood and the face frame is poplar and the dimensions are 18" x 9" (the cabinet is pretty square).
What is a good margin to leave so that I won't have issues with shelves sticking due to expansion, paint layers (over time), measurement tolerance etc.
I made a blank of 1/4" plywood that had 1/16" margins (17 7/8 x 8 7/8) which certainly would give enough room but I'm wondering whether it would be wise to tighten them up a bit to say decrease the margin to
1/32".So what is a standard margin for a good quality cabinet in such a situation. (I know this is not a scientific question but I wanted to get input from people who have built such cabinets before)
