Finished the rollers tonight by adding the walk planks and pulley. I had to add temporary feet as the pulley will be partly below floor height. Working on the tracks the carriage rides on but not far along enough for a picture yet.
Thank you all once again for the positive comments. It's nice to know I'm on the right track. Here is a shot of the rails the carriage rides on. I didn't order this kit so I had to make it up following the pictures. The pulleys are some HO stuff with every other spoke removed. The drive wheel? is a cut up machine screw, pillow blocks from plastic. Nothing is glued yet. Just set in to see how it will look.
