Thanks to marshelangelo for reactivating this thread. My father introduced me to Marx/Lionel back around 1950 & this is one of the most impressive projects I've seen to date. I've read the 10 page thread & watched all the videos over the last 3 days. All the superlatives have already been used & all I can add is my own WOW! I've been using TMCC & DSC for over 10 years, but am new to OGR (thanks to LHS). I can't decide what my favorite area is; there are so many. It comes down to the Trestle, TT, & Subway Mall. I also like the eclectic style of weaving the Game of Thrones, Downton Abbey, etc. themes into the videos.
My wife has been after me to free up some storage areas & your under table cart idea is perfect. I plan on moving the swinging/hinged doors & attaching them to the end of each cart. When the carts are in place, they will be located under the table using 1/2" dia. tapered pins & bushings in each upper corner.
Thanks for the education.
To me, you are ingenierio/artista, a true Renaissance DaVinci!
