Basic Information

About MrWhoopee
I am a recovering machine shop owner. I studied machine shop, welding and drafting at our local Junior College in '78-'80. Apprenticed at a small job shop, rising to shop foreman within 3 years. Opened my own shop in '89, growing to 15 employees. Sold the business to my partner in 2001. I've been in recovery since then. Decided it's time to start making chips again.
