My flexi plan was to basically copy the Mapleshade rack.
2" thick maple shelves, with 3/4" or 1" threaded rod at all 4 corners.
I don't think it would be too light....
I just like the look/sound of the thick maple shelves
I like the idea!

I'm in the process of doing something similar myself...kindof a bastardized version of it...and certainly, a cheaper version.
Mine will be double wide, 50 inches, and 3 (maybe 4) shelves high.
Instead of 2 inch solid maple, mine will use 1.5 inch thick butcher block planks, finished with bull nose edges.
I don't have all the materials yet, but I got a start on it.


See my gallery for other pics.
I need two more shelves, and the cinder blocks will be replaced (obviously) with Stainless Steel threaded rods. Stainless is more expensive, but it will hold up better against rust, oxidation, staining, etc. And I live in a beach community...all the more important.
I've thought long and hard about the appropriate size for the rods. I really like the hefty look of the 1.25 inch ones used by Mapleshade, especially for a rack this wide. So I figure to be visually pleasing, 1 inch is a minimum. I'm sure smaller diameters will do the job structurally, but I feel that against the thick and wide shelves, it will just appear too flimsy. Thoughts, anyone?
I don't know about the "sound" of this rack...or if I am even on the right path in this regard.
And I have no idea whatsoever about the sonics of solid maple vs. maple butcher block.
But I do know it will look good, be
very heavy, and once bolted together,
very solid.
The 1.5 inch butcher block I'm working with is easily 50 lbs per shelf!
