Hi Paul
The plywood is going the way of the candy bar getting smaller and smaller if they can save 1/32 of stock when they make the plywood they can many more and still charge the the same price.
At some point they will need to tell you and I that the stock is unsize that's to say it's not 3/4" it's not 23/32" but now it's 22/32" and next week it maybe 21/32" I see no end to this.
Just as a side note, they are building some new homes down the road and I stopped by to just have a look see, the roofing plywood was marked 5/8" chip board but it looked like 1/2" T & G to me and when the roofer was putting on the roof it bent like 1/2 " on 16" centers when he walked on it.
And the new homes are 450,000.oo not cheap homes.
I recall when a 2 x 4 was a 2 x 4 but now days....well ,the way of the 5 cents candy bar.
And I think that's why the MDF and the WoodStalk will take over the plywood sales.
For one thing when you and I buy 3/4" MDF it's 3/4".
And when you and I buy 3/4" WoodStalk straw veneer it's 3/4" so you may want to stay away from veneer plywood.
