I want to put up a quick and cheap set of shelves over my desk, and for various reasons I want them free-standing over the desk on legs. I was thinking of something like a frame:
front view
|----------------------| | | |----------------------| | | | | | desk sits in | | here | | |
(so there can't be long crosspieces at the bottom) width about 1600mm
side view top view |----| |--------------------| | | | | |----| | | | | |--------------------| | | | | | | |----| depth about 300mm
with the shelves themselves just being 6mm board nailed to the crosspieces. Maximum load maybe 20kg per shelf, distributed.
What would be a suitable size/type of timber rod to use for such a frame, that is readily available?
(I first thought of metal box tube construction systems, but that would come out pretty expensive.)
