So I'm making several studio scale models (USS Grissom, TESB Millennium Falcon, A-wing fighter, etc.) and I was hoping for some recommendations on dimensions to make a general-use threaded connector. I'll be using metal, or wood-and-metal hybrids to make several of these so I can just grab one and install it in a model, and I'd really like to use a thread gauge that is commonplace enough to find in a hardware store, and which will be thick enough for large-scale models that weigh 30 pounds or more. My Millennium Falcon is probably the heaviest in that regard, or will be when completed, plus it might not be the biggest or heaviest model I will be making. I'm a little out of practice with thread gauges this large, as most of my needs so far have been met by smaller gauge bolts.
