Ask HN: Where can I find the HN of Manufacturing Operations?

I appreciate the wealth of information about technology offered by HN. Hence, I am looking for a software/hardware hacker community/resources focused on manufacturing operations. I am aiming to capitalize on the oportunities arising from the pain ubiquitous in Oil/Gas equipment manufacturers and mom/pop machine shops (to which a great percentage of the labor is outsourced) in Texas. Time to bring Oracle at al. down from their ERP pedestal.
