Stopped by Portland HD to check out their sound board, it's soft and "crumbly" to me. It would have to sandwiched on all sides to avoid the shedding. Took brief look at foam insulation and very impressed by how dense it is. Great excuse to get a hot wire cutter!
90% sure I'll top off my small pike with 2" foam. Need cut track supports for the open corners and fill in open strip in the middle. Legs need more bracing as well.
Here's bench after laying 3/4" birch plywood on top.
Decided to leave some open areas for below grade scenery.
I'd like to place my Lionel Lighthouse in one of the corners.
