I know this topic has been discussed a lot but I couldn’t find a clear answer to my question. Or I am lost in too much content without clarity on my particular question. I am building kitchen drawers from 1/2’’ white oak (flat sawn) with 1/4’’ plywood/MDF bottom (MDF would be surfaced with linoleum). The largest drawer is 30 5/8’’ wide, 18’’ deep and 4 1/2’’ high with Blum undermount drawer slides. Construction uses dominos for joinery and 1/4’’ deep groove for the bottom offset by 1/2'' (1/2 is required by Blum).
How should I account for wood movement in this construction with hardwood sides and plywood/MDF bottoms? I am in New England, hot and humid summer. That means the drawer sides should shrink in the winter. Does that mean I should use a 1/4’’ deep groove and undersize the plywood/MDF bottom by 1/8 so that there is space for the sides to shrink? Do I glue the bottom or not?
