The big one is 48” x22” x 22”. The small one is 23 x 16” x 16”. No plans...just started building. I had a stack of Sapele and I built to suit the supply, trying to use it all. I used some fancy veneer shorts for the backs. But the construction was the same.
The carcasses were frame and panels with a veneered back and bottom. The front and back were put into shallow rabbet in the edges of the sides., glued and screwed. The bottom was captured in a dado in the back and sides.
Now you have a big box.
Then I cut rabbets the full length of the 4 leg stocks. I glued a small block back into the bottom of the leg rabbets about 3 “ long, depending on how far up off the floor you desires. Shape them as desired. Now you have 4 legs with a groove that I glued to the corners to hide the corner screws. Tops are pretty straight forward....spalted veneer on 3/4 Baltic birch.
On the big one, I used the new hinges that Rockler developed and I will not use anything else. They have tension built in, so you do not need a rod or spring to hold the top open. The small one was too small for those hinges so I-used a short piano hinge.
Any specific questions ?
