Scarf Joints in Plywood

The classic Bingelis library has info on setting up a motor and a
sanding drum, but that's probably overkill for 1/16 unless you're doing
a lot of it.
If your plane isn't razor sharp, a long sanding block with medium grit
will work fine. Just be sure to blow the dust off (do not use a tack
cloth). Rich is right - the plies will give you a good visual
indication. They should be evenly spaced.
You might plan on having some extra at the other end (if possible) in
case you mess up and have to cut a strip off the end. Practice on a
piece or two.
The only down side here, is that sanding is considered to be a poor surface
preparation method, for glue joints. I think I recall that fact from the
Forrest products publication.
The surface should be scraped to prep for glue, at a minimum.
