what kind of finish are you trying to remove? that might dictate to some
degree how aggressive you'll need to be, and whether you want to try
chemical strippers instead of just sanding.

As for sanders, using a belt sander on plywood is probably not a very good
idea in any circumstance. I've used a ROS many times, but you have to be
very careful and not tilt it or let it stay in one place too long,
especially if you use aggressive grits. In many cases, using a sanding
block and elbow grease is the best way to control what you're doing.

I have, or had, plywood panel until I went too aggressive with the belt
sander. Looks pretty good except one small spot where the first ply was
completely removed.

So what would be the best sander for this? 1/4 sheet and 5" ROS? Which
ones?
