Now I'm really looking forward to your follow-up.
And Liquid Nails is everybody's friend!

Ok Dave,
First I figured what the radius for a 96" sheet would be ~ 61 1/8" (little over 5ft. Perfect!)
The day before I glued a stick and a half of aluminum tile edge to the concrete floor
Then since I had to fur out the wall 3/4" to flush the drywall above I glued a 1x4 to the concrete wall @ 61 1/8" on center.
Next layed out three whole sheets of 1/4" Luan Ply ($10.97 each)
Place and glued 90" x 24" rips on the seams to join them
And ~ 6" rips on the two ft layout and the edge (this is backing to staple the top staggered layer of ply) Also added horizontal pieces in between for extra backing top and bottom.
When adding these backing strips I started them 1 3/4 from the top of the panel, so when I pushed the dried panel into place to form the radius it would catch right under the 1x 4 attached to wall and snug right up against the upper panels. First layer of upper panels I started with a 2ft panel to stagger from the bottom.
The rest is pretty straight forward. The next day when the panel done throughly drying .I ran a couple thick heavy beads of Liquid nail on the tile edge and the concrete. Then I flopped the panel upright and placed the bottom in the lip of the tile edge. I pressed the panel down until the panel was centered on the 1x4 on the wall. This was easy because with the 1 3/4" spacing I left just let it snap into place forming a perfect radius.
Next I added the staggered seamed top finished layer. I glued and slipped a 1x4x12, 2x4x12, 2x6x12 and 2x10x12 under the radius area of the floor for plenty of support and after screwed glued and screwed its rock solid. I could have purchased treated material for this but I had this material on hand and with the liquid nail in between the concrete and the wood it will help prevent and wicking and will last much longer than I will need it to.
