Woodland Scenics WC1250 Rock Mould - Tunnel Liner Form.
This innovative mould is ideal for casting realistic rock walls and ceilings for scale tunnels on your pike. It is designed to form half of either a single or double liner section with each pour of lightweight Hydrocal.
Use a spatula to fill the tunnel liner form with lightweight Hydrocal. Join two half sections on top with a strip of plaster cloth to form a hinge. Join completed units on one side for a longer tunnel. The unattached side can be raised for track maintenance.
