To rebuild or not to rebuild?

[RobertInOntario]

Robert, if the plywood board has warped, I would suggest getting some steel studs designed for wall construction use. Remove the old frame, all structures, and any removable details, and lay the studs on a couple of saw horses with the plywood layout board laying on the studs. ...
The only reason that I can see for actually tearing down the layout and starting over is if you are going to build a bigger layout, or have decided to radically change the track plan and it is easier to remove and replace everything than it is to modify the existing layout.

Thanks, Russ -- I appreciate this info. I guess I could buy the steel studs from Home Depot and similar places? Rob
