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 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 which forms a hinge.
Join completed units on one side for a longer tunnel. The unattached side can be raised for track maintenance.
Sized for HO, modified for N scale easily
*Hydrocal is a U.S. Gypsum registered trademark.

CAUTION: Tools recommended. Use with care.
Tunnels can be made in a variety of ways.
Ready Landforms are an easy way to add a tunnel. They are preformed, landscaped and ready to place on a layout. Available in HO and N scales and straight or curved designs.
Self-supporting Shaper Sheet is another easy way to add a tunnel. Form into tunnel shape and arrange over track. Cover in Shaper Sheet Plaster and add landscape materials. For added realism, paint underside of Shaper Sheet to resemble blasted rock.
Use 1/4" Foam Sheets or 1/4" Modeling Sheets to make tunnel walls and roof. Use No-News Paper or newspaper to add paper wads around the tunnel foundation to model terrain, and add a double layer of Plaster Cloth to form a hard shell.
Use the Tunnel Liner Form to mold tunnel sections from Lightweight Hydrocal, Shaper Sheet Plaster or Super Strength Plaster. Connect sections together with Plaster Cloth to form desired length of tunnel.
