Back to Model RR Gallery Tunnel Portal The pattern came from a photograph that was enlarged to scale on a copy machine, then traced onto a piece of foam. This was cut out on the Hot Scroll Table. The top stones were cut out separately and glued on top for added dimension. The details were made with the Engraving Tool. This piece still needs to be painted and weathered before it is glued in place on a model railroad diorama. Tip: Use this technique to make stone, brick and coblestone walls and roads.
