Nice, Jack. I hadn't thought of using allthread. I'm guessing it
creates a very rigid surface and takes some of the bounce out. Did you
lay a ply top over the boards? I ask because I'm not sure how to
proceed.

If I use finish nails it will eventually come loose, but gluing it down
with liquid nails seems a little too permanent.

I'd use liquid nails. When the top gets too old to scrape
clean, your grandkids can scab on a new piece of plywood and
it'll be good for another 30 years. grin
