unknown member has decided to play Games Workshop's new War of the Ring in 15mm scale, and is working on new bases and models. His pictures can be found in four galleries here (scroll to bottom of the page).
What I am doing is using 15mm round thin bases from Litko Aerosystems with their thin metal bases attached. Then the movement tray is a 1.25" x 2.5" wood strip with a magnetic sheet attached.
