Rolls of thin wood to make your own plywood. You want all hardwood.
You want water-proof glue. Not white or yellow. Maybe (Maybe) liquid nail
stuff. Apple-ply - but you want a little bend in the ends.

The curved deck was developed over years of riding. Easier when skating.

I have (my sons) a deck that is likely 3.5' long and at least 12" wide.

It was a trick and fun one. Trucking types are narrow and long.
More like a ski.

Use quality trucks and mounting system. They save ankles.

I can buy a cheap skateboard for $20 US, but I would prefer to cut
my own. I do not want concave or springy, it needs to be strong

hardware stores that might work for a skateboard deck? Ordinary 1" x
8" (or 12") wood? Plywood?

Ash? Hickory? Stuff of baseball bats.
