I had a rainy day and couldn’t work, so i got to spent about 4 hours making the boxes for the base cabinets. I decided to go with the baltic birch maple plywood mix after listening to comments. here is how they turned out.
These are put together with glue and nails i hope that will be strong enough. The joints are all rabbited or dado. I did use a few screws where i thought it wouldn’t show.
