2/11/23 - I have about 95% of the O gauge bench work framed up. I still have to frame a low area for a trestle section and add some additional joists and extra leg on the other island. All of the O gauge and standard gauge sections have been connected together with screwed blocking, basically making the whole layout one solid piece. Top of the O gauge joists is set about 36-1/2" above the floor. The O gauge track will be installed over the open grid using strips of plywood road bed and risers. That will be a whole new learning curve for me as I have never done that before.
Fabricating L-girders and leg assemblies in the shop.
Assembly in the train room.
Everything buttoned up in place.
