Otto, The great modeling aside, I’m really impressed with the engineering you are putting into this.  Looking forward to seeing the progress, especially how the bridge will fit on the bearing and the power pickup parts.  Is it going to be motor driven too?

Thank you Steve, appreciated. Well, the “engineering” is evolving, but I knew I wanted to start with a solid bearing large enough to support the full bridge. The bearing has an opening of .5” i.d. and I have a .5” o.d.steel tubing that press-fits inside it. Beyond that, I have a general notion how to make it work, but for now I need to make sure I can make the bridge look and work right. Today, cutting and testfitting the bridge deck, pics below. I’m basically cutting up various bridge kit parts to make a partial turntable “kit” from which to build this thing. As you can see, I have a ways to go....
Thanks for your interest,
Otto

Thanks guys, I really appreciate the nice comments from all three of you.
But...😬 I’m still struggling with this thing. Had to make some compromises I’m not too happy with, so the jury is still out on this one. It will be a couple of days before I can get back to it (still “working” on the monster PCL HO layout three days a week). The dilemma here is/was the beautifully rendered cross bracing which would look great (but would be wrong) for the top of the main beams, vs. the correct zig-zag bracing (which is correct in detail but adds too much mass and thickness to the beams).
I went the “correct” route, and I’m not sure it was the right call. Time will tell...tbc in a few days.
Here is a pic of the steel sleeves and resin insulating plug. Still waiting for the motor to arrive from Amazon.
Thanks again, Otto

I know it's a pain in the a$$ but you could use paper for the zigzag bracing if you're looking to go thinner.  Paper is soaked in CA is what i used for the tender steps on the whale back tender. They came out very thin.

Hmm, good idea, but I’m not sure I have the skills to do *this* out of paper. And I need a lot of it...

If you have or know someone that has a digital cutter, you could scan it in and let the machine cut as many as you need. Just a thought

Otto, if you have a way to scan it in and provide the measurements I would be happy to try to cut them out for you.

Thank you, that is very generous of you @Wolf N Works!
However, I think I convinced myself I can live with the plastic molded parts. The detail is exquisite 3D and the thickness is off by a few one thousands...
Thank you anyway for the offer.
