Yellow carpenter's glue sets up in about an hour. By the time you wait
around for the contact cement to get dry to the touch on both surfaces, the
time differential is not great.

Besides, I'd bet carpenter's glue holds better than contact cement. I'm
constantly having to re-fit pieces of high pressure laminate on countertop
edges because the contact cement failed.

Rather than clamping or nailing shelf edging 'til the yellow glue sets up,
what about contact cement? I know that the wood cannot be repositioned --
thus the word "contact". I am thinking of a wood edge rather than edge
tape. For 3/4" ply, I'd use a 1/4" thick slice of 5/4 and then route the
part that overhangs above and below the ply. WIll contact cement hold as
well as yellow glue and clamping?

A concern is that staining might be a problem if there is any
squeeze-out/drip onto the ply. I haven't used contact cement in a while
and don't recall if it is possible to roll some on the edge of the ply w/o
it unavoidably ending up on the surface of the ply.

Comments? TIA. -- Igor

I have used contact coment for gluing solid word trim to plywood for
the last 25 years and have never had any of the edges come off. I used
solid word to cut my trim and glue to to 3/4 or 1/2 plywood and router
of the edges that extend on both sides. Normal 1 inch solid is just a
bit wider that 3/4 ply. A little scraping and sanding and the edge
looks like the edge of solid wood. I have used bits for trimming
formica with either a straight or a bevel. I prefer the bevel bit.

It works,
