Thanks.
I completed the base structure this week.
It's a hefty construction but I wanted something durable. I'm starting to lean toward incorporating this into a free-mo module. The local club is currently making a free-mo layout and I'd like to ask them what it would take to adapt this.
And here is the trestle in the base. I'm going to have to nip about 1/16 off the upper stringers on both sides so it will settle into the base's ends without being pinched but other than that and a tiny bit of shimming, it fits well.
Not I can start repairing the popped glue joints on the trestle itself.
I made this fixture that will hold the trestle by the stringers on one end and the howe truss on the other. this allows the parts that have become unglued to 'droop' apart so I can apply glue to set it back up.
When the trestle is suspended I can see that it is coming apart between the first and second 'stories' Since this model was built prototypically, The lower bents are three cross braces high with joists forming the foundation for the next 'story' that are two cross braces high. The attachments of the second story bents to the joists are coming apart.
My plan is to place a small drop of carpenter's glue on the failed joints while the trestle is suspended, then place in back down on a flat surface to let the glue set up.
I hope this is making sense, I don't know all the terminology of trestle engineering.
