Modeling the GNR?
The Society regrets we cannot answer your specific GN modeling questions. The quarterly Great Northern Goat is a tremendous resource, and back issues of the Goat's Modelers Pages are available below. For specific questions your best bet would be to join the GN Online Discussion group and post your modeling question there. We provide the following links as a courtesy to aid your search.
