Q&A for How to Bend Plywood

It depends on orientation. If you cut five identical, long, curved shapes from a piece of 3/4 inch plywood, and glue them together, you will have a very stout roller/rocker leg.

Choose a thin and bendable wood, usually 1/8 Baltic birch ply, and screw it down to a form, usually 2x4s because they're cheap. The bend on a ramp usually isn't very severe since it is usually at least at waist height (let's say 36 inches). That height is the bending radius and usually plywood of that thickness can bend considerably more tight (up to 24 pretty easily but sometimes much more).

Kerf bending works well with walnut where the inside radius is hidden and you have a curved frame to glue it to. You also can steam bend if the inside radius will show.

If done in pieces, yes, but otherwise no. Look into how boats or wooden kayaks are made, as this is the process you would have to use.

Yes, that is the quickest way to get an accurate bend, 20 minutes of steam all over and hold it in a form.
