I have never built a tabletop layout before but I"m thinking about doing something other than a standard 8x4. I’m down to two possible track plans that would allow two train operating on an 8x4 layout. But I’d love to add a large oval around the perimeter (even if it isn’t connected with the inner track) to add a third train and be able to run a slightly longer train that can stretch its legs a bit more. But that seems impossible on an 8x4 or it would have to run right at the edge which I don’t want to do. A 9x5 would allow that third loop and give me a little buffer room at the edge of the layout but it raises a lot of questions in my mind about construction especially since this is my first try. Part of me says stick to the 8x4, a two train plan is good enough, and learn the basics before trying something harder. Part of me feels the three train 9x5 option would be a lot more satisfying in the long run, could work in the limited space I have, and might be worth the extra headaches building it. Any suggestions? How much is it going to complicate my benchwork and construction trying to add that small extra space assuming I’m not going to find a 9x5 sheet of plywood? Thanks.
I don’t see it as that big a deal - Sketch out what you want, go to your local lumber yard and then have at it - Use cut down 10’ 2X’s for the long runs and then cut 8’s for the short and cross supports - For sheathing (top) you can mess around with a couple of options to minimize waste - get out some paper and start sketching - Somtimes you can find odd shaped pieces in the “scrap” bin at Home Depot Or Lowes - So for a few bucks you get what you need in addition to a standard 4X8
Now if you use foam or homosote on top for sound control you will have to obvioulsy buy and cut more then one 4X8 sheet
But if you are going to do it, take the time and do it right or you will regret it later! (and then spend more time re-bulding it!) This rule applies to all projects and hobbies!
Having said all that, I cant speak for the practicality of this as it applies to track plans - In that are I am still learning!
Good luck and have fun!
5x9 layouts are not so rare as you might think. Lots of layouts have been built on what used to be a Ping-Pong table, which happens to be 5x9[:)]. When I built my current layout I made it 5x9, so I could run bigger steamers and not have them look too silly. If you have room for the 5x9, go for it!. Just make sure that you have access all around the table, as you must be able to reach into the middle! When I built my benchwork, I made the frame in 2 halves(5’ x 4.5’) and I used the expensive cabinet grade “Baltic Birch” plywood for the top, as it comes as a 5’ x5’ piece. IF you can afford it, it’s IMHO the best way to go, as it is very flat and does not warp.
Since the plywood was almost 3/4" thick, I used 20" centers for the underside supports as that was adequate, as the entire frame was glued and screwed into one ridgid structure. There are books available that can show you how to build benchwork, I don’t remember the titles right now, but I’m sure that someone else will be able to mention the name of the book–
HTH!
Just make sure you don’t have to reach 5 feet across the layout if the need arises. Best to leave a 2 ft. crawl space between the layout and the wall. If it’s going in the middle of the room no problem. Although my layout started out as sort of an island. It eventually went sort of around the walls. I myself sort of prefer to be in the middle of the action. I also found maintenance and scenery wise it’s easier dealing with a more shelf type layout. A backdrop can add a lot of scenery and depth and around the room seems to make the layout larger than it is.
These photos may give you an idea or two.
