Ever have a day you should have stayed away from working on the layout? Today is my day. Deconstructed a finished rock wall because there was not enough clearance for the cylinder head overhang on an engine to make the curve to go onto the branch line. Now this was not a simple process since there is a 1/2" plywood backing to the rock wall and screwed and glued to the benchwork. So cut to rock casting rip out the plaster/cardboard strips, expose the plywood now cut the plywood ro shift it back 1 1/2 ", crawl under the benchwork and remove the supporting 2x2s . These bones are not too keen on crawling under the layout. Finally cleaned up the debris from cutting back the upper shelf the rock wall was attached to and now time for the replacement rock castings. Paint the mold, let it dry, finish pouring the resin and foam when I remember that I had not lined the mold with petroleum jelly releasing agent. Spent the next hour breaking out the resin/foam mess that was supposed to be the rock casting. Well, I raised the white flag and retreated upstairs . I decided I needed to log onto the forum and take encouragement from other forum members successes. Thank you guys, Mike
