Don't despair. you can build a pull out in almost any width, depth or height you have to work with. I can help-long distance like.
The dimensional wood is Maple and the rest is 1/2' Maple faced "Apple ply" and some Maple shop ply were it doesn't show. I hand rubber 6 coats of General Finishes "Salad Bowl Finish" inside and out. I did build all of the cabinets myself. However I did have some design help from Uwe at Area63productions in Orange, CA. Uwe is the master!
The slides on the bottom are Accuride 3600-201-c ,175 lb. and the top is an Accuride 3832 , 100lb. I think I ordered through thehardwarehut.com I think they were less than Rockler.
Paula, I did consider a couple of options. Integrate the door onto the pull out, no door, etc. However the DW convinced me that it would look better if it had a door that matched the rest of the cabinets. Who am I to argue
Yes I fabricated a simple pin to lock the pull out from sliding and the door has a magnet to keep it closed.
