Try Boulter Plywood Corp. in Somerville, Massachusetts,
http://www.boulterplywood.com/  They have or can get most anything.
I've seen nice quarter sawn white oak there.

You may have to laminate something like 1/4-inch onto a 3/4-inch
substrate to get 1-inch material economically, or two 1/2-inch pieces
back-to-back if you want a good figure on both sides.  This is pretty
easy to do with a vacuum bag veneering setup.  It will cost a lot less
than custom ordering 1-inch ply.

I'm always sorry to read something like this, because it's just not
true and is unnecessarily discouraging to people.  You may not like the
price, but there is plenty of absolutely gorgeous quarter sawn white
oak lumber and plywood available.  No, not at the Home Despot, but not
much farther than a good Google search away.

I've seen good to excellent quarter sawn oak lumber at at least two
retail lumber dealers in the Boston area (Boulter Plywood and Woodcraft),
and if you go to someone like Talarico Hardwoods or Irion Lumber in
Pennsylvania they will be happy to sell you the best stuff you've ever
seen (and yes, it will probably cost $20 to $30 per board-foot), e.g.,

The ads in the back of Fine Woodworking are a great place to find
obscure wood, as is eBay -- many of the people who sell specialty wood
by the board there will be happy to send you a couple hundred board
feet if you ask.

Learning how to fume it with ammonia is the next step in really
matching the old appearance.  There have been good articles in Fine
Woodworking on that as well.

I don't mean to knock the idea of recycling old wood -- it is a good
one.  There was plenty of nasty furniture made in the last century with
very nice wood that can be economically reused.  If great new material
is what you want, however, it is out there if you look for it and are
willing to pay the price.  I think it's worthwhile supporting the small
companies who make high quality materials like this available.
