I just finished this materiel platform for my layout. It needs a little stain and weathering just so it doesn’t look so clean.
Now I have to fill it with barrels, crates, etc. then design and build a warehouse for the goods that need to be under cover, gun powder etc.
For the deck, I cut a pieces of 3/16" cabinet plywood (3-1/2" - 4" scale), I used a table saw rip blade I modified by removing the set on the teeth then filing the teeth to a sharp point. It cut 1/16" deep grooves random width, I then used a 1/4" chisel to mark board lengths and trim some of the ends a smidge.
