[quote]QUOTE: Originally posted by bnnnboy Well, I will show you some pics of my mountain tunnel. I made mine out of 2" foam stacked and then carved/sanded down to shape. http://community.webshots.com/photo/109373438/205281499jUbLXW this is the mountain after I have shaped it and patched it with some plaster cloth. Just remember to paint the inside of the tunnel before you put the top on it. http://community.webshots.com/photo/109373438/205281618xbIMHg I put the tunnel portals in place and, after making sure that the foam on the inner tunnel did not stick out when the portal was in place, I supported the portal and filled the gaps with expanding insulating foam. I used a latex-based foam called DAPtex, but it dried soft. I don't know how it will react with the insulation foam currently on the layout, but I know that Great Stuff dries harder and thus will create a more stable scenery base. http://community.webshots.com/photo/109373438/215080325HaPeex Then, after I shaped the foam and the mountain to create a more gradual transition to the portal, I covered the insulation foam with plaster cloth, providing a better scenery base. As this photo shows, I also covered the inside of the tunnel transition with plaster cloth. That's the basic idea. Reed [/quote] Bnnnboy, did you create any "trap doors" to rescue derailed equipment inside? If so, how did you do this and if not, why not? That's the statge Im at right now and was wondering that for those who created tunnels. Thanks, J1
