A couple of reasons, firstly they're made out of cheap bunnings ply. Which I
found out later are glued together using even cheaper water soluable glues.
And secondly I'm seeing ply swelling problems on the 8" the Estypol I used
which I have also used (finished off the can) to spray the 16" Sec cage
isn't sealing the wood, as I had hoped.
I have enough 9mm hoop pine left as well as nearly a full sheet of 1.5mm
hoop pine I can laminate the 9mm with a few layers of the 1.5mm.
Bunning 9mm ply has 3 layers, the 9mm hoop pine has 7 layers an looks a lot
nicer.
