17. Liquid Nails for projects cleans up with water, has
no nasty solvent vapor outgassing, and gives me up to
15 minutes to get the layers clamped. I was amazed
at how much adhesive it took for each 4x8 sheet – at
least two tubes. The trowel has 3/32” notched edges.
I used flat head deck screws to attach the first layer to the ceiling
cleats and the roadbed edge below [18]. The plan was to laminate
the second layer right over the screw heads – a risky proposition
because once it was glued together, there was no way to get it
apart again without a lot of destruction.
Another train buddy, Jim, helped cut a 3’ piece of plywood to start
the second layer, ensuring the end-of-sheet joints in the layers
wouldn’t line up with each other. I squeezed out what I thought
was a generous amount of construction adhesive on the first layer
