Tunnel Liner Former Mould

(HO scale) This innovative mold 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. Use a spatula to fill Tunnel Liner Form with Lightweight Hydrocal. Join two half sections on top with a strip of Plaster Cloth which forms a hinge. Join completed units on one side for a longer tunnel. The unattached side can be raised for track maintenance.
