I am a new builder that is planning to build a Christavia. My goal is to start building the wing ribs this Fall with my teenage son. However, it seems that the supplier for the 1/2" X 20 gauge and 1/4" X 20 gauge cement coated brass nails are no longer supplied anywhere. Where can I get some nails for building the wing ribs? I plan on using T-88 epoxy as well. Any suggestions are appreciated.
