I once built a shelving unit out of maple veneered laminated 3/4" plywood. It was 42" wide, 19" deep. Single sheet shelves only. The resonance was brutal. This time around I was simply going to double up the same shelves but use construction adhesive to sandwich the shelves together for a total of 1.5" thick.

** My preference is to find solid 1.5" shelving, maple etc**

I have even seen butcher block shelves. I have combed the big box stores, and nothing beside 4x8 sheets of you name it.

Where would I go to find solid thick basic lumber shelving?

Greg.......You will have to seek out hardwood suppliers. Take a look at woodworkerssource.com as a starting point.

Dan, fantastic, thank you, I will check it out

Greg.......The few times I have purchased hardwood, I had to locate the specific hardwood dealers. Most lumber yards only deal in construction type lumber. Call a few custom cabinet makers and ask where they buy their hardwood.

I built amp stands using 3/4" oak plywood and MDF to get 1.5" thickness. The outer edges are trimmed with 1/4" oak ripped to 1.5"s I stained them with Watco's Danish oil. Golden oak finish adds just a little orange color but is very neutral, almost clear. They are non-resonant, dead !!! Loews carries the stock in 4x8, 4x2, 2x2 sizes. They have maple and birch too.

That sounds good. (no pun intended)
Heres another option.. LINK
you might find that these these guys [oliverlumber.com] superior products and selection than that of the big box retailers

Hey thx fellas, as a cheaper alternate I just finished using a double wide maple veneered plywood 3 shelver I built, doubled up the 3/4" shelves and it was dead quite too, huge success. I am going back to a single tall config to get the tt a little higher etc. This time 1"1/4 bolt/rods, and triple thick 3/4" shelves. This will be a very solid, very heavy and a dead quiet solution. The finish I need to work on...

Veneered or stained void free, 13 ply, 18mm Baltic Birch would be a better choice. Laminate 2 sheets or more together and you'll have something very solid. For small and medium sheets I usually buy from Rockler.com.

Face, ok, I will investiagte this as an option for sure!

I noticed you are in Toronto.

For hardwood (you may need to do your own fabrication) try Peacock Lumber in Oshawa
