finally building layout

[Bigsteel]

i wouldnt want to abandon this yet,could i add 2 more pile inside the ones there and add more bracing then add some more logs lengthwise? i was thinking about making the inboard logs into wooden trusses.im not sure but would that beef this up enough.but remember the F-unit was just for size comparison.it will only be holding shays and small diesels.--josh
