@mowingman posted:I read your post wrong. I do use glue to hold the Homasote to the plywood. I just spread some "streams" of wood glue back and forth across the plywood, then lay the Homasote on it and weigh it down with bound volumes of train magazines until it dries. I usually put a few screws around the edges to make sure it stays down tight when the glue dries.
With small streams of glue, the Homasote stays down well, but it can still be pulled loose if you ever need to remove it. do not paint/spread a layer of glue on the plywood, or, your Homasote is pretty well down for good and pulling it loose is not possible.

Sounds like a good plan, Jeff. Thank you! Stuart
