Another "nice rack" to you Dave R. I'm taking woodworking classes through adult ed here. My first solo project is a turntable stand made of white oak. I was going to modify this design:
to be about 40" high with three 30" x 20" shelves, but I think I prefer your design so I'll probably do something like it instead.
Your design would be more stable and I wouldn't have to go through the effort of drilling holes, cutting legs and drilling legs and lining everything up on assembly. Yours also gives more usable space on the shelves. Of course, it adds the complexity of cutting dados but that's easy enough to do with a table saw.
Hope you don't mind if I do use your design. If so, please let me know.
