There's a "magazine" (more like a broadsheet the size of the grocery store tabloids) called Farm Show. A lot of times they'll include short articles about people manufacturing out of production components for things like tractors and farm implements. You might try that, maybe someone is making carbide inserts?

I'd be willing to bet they may also be interested in featuring An American Homestead in some articles.

Thanks! I will check it out!
