Our HO Scale sidewalks mold is made from silicone rubber, which allows for extreme accuracy in producing plaster castings.
Photographs of the mold and of the plaster castings it produces.
This silicone rubber mold produces HO Scale sidewalks that are 5 feet wide with a 6 inch curb and are representative of sidewalks that were in use before the handicap accessible laws were established.
The tread surface is textured with the curb being smooth giving it the appearance of having being cast in a concrete form.
Each cast will produce the following parts (both with and without curbs):
Strip of six 5×5 foot square sections
5×5 foot section
5×8 foot section
5×10 foot section
It also includes both left and right curved ends with curb. Each of these is a strip of two 5×5 foot sections.
For ease of casting and handling, the castings dress out to .200 inch and are intended to butt up against a previously installed road that is approximately ⅛” thick.
Prototype sidewalks normally range between 6” and 8” in height. With an HO Scale inch equaling .0115 a scale 6” would be .069 inch.
A ⅛” thick road (which would be .125) butted up against the sidewalks (which are .200) results in a sidewalk that is .075 or 6 ½ scale inches high
