I will be building some slide out shelves for our kitchen pantry. I estimate the shelves to be little over 14 inches wide and 22 inches deep with 1/2 maple sides dovetailed together about 3-4 inches tall. My question is if I use 1/4 inch maple plywood for bottoms is that going to be strong enough? the glides will support 100lbs. I would hate to build them only to have the bottoms fall out. I am planning on doing dados for the plywood bottoms.

At 14” wide, I agree with jbay. ¼” plywood will probably be ok. However, your question suggests a worry which is easily addressed by using ½” plywood which can be rabbeted to fit a ¼” dado in the sides. If the glides require a ½” bottom clearance, this means you lose a ¼” of spacing between the shelves, but you gain peace of mind.

Personally, I would never use 1/4” thick bottoms in a kitchen slide out if for nothing else every time you put a cast iron pot on it you will be reminded that you went cheap with the drawer.

I doubt it would ever break, but why not just go 1/2 and be sure?

Start the dado 1/4” from the bottom and make it a full 1/2”. Don’t worry about losing space it won’t matter in the end.

When I built my kitchen I predrilled shelf pin holes in the sides and mounted the runners to a 3/4” strip (needed to anyway to clear doors. If you have a face frame you will need them anyway). Placing the runners top of the pins you can have adjustable slide out shelves. This worked great especially when my wife decided to store the crockpot down there.

Oh yeah, and you need to put a screw in the back to keep it from tipping when pulled out ;-)

Good luck with your project.
