Hi.  I’m John C. Carlton, a currently unemployed mechanical engineer and designer currently living in Southern Connecticut.  I graduated from the University of Bridgeport in 1988, a university who’s motto was, when I attended; “Educating For The Real World.”  That education must not have taken because the real world keeps hitting back.

I have over 15 years experience in mechanical design and product development.  I’ve worked in places as varied as a compressor factory where the technology was straight out of the 19th century and a DOE physics lab where the stuff I did left the cutting edge about five years back.  Lately I’ve been designing high end laboratory instruments like mass spectrometers.

I have always been interested in industrial history and railroads.  I’ve been known to volunteer at the SONO Switch Tower Museum giving presentations to everybody from politicians to five year olds.  I also visit most of the local technical and railroad museums frequently and am a member of many of them.

I seem to acquire hobbies like barnacles and have a bunch. I like computing and the internet(I bought my first computer in 1982, an Apple IIE). I’ve been a scale modeler and model railroader since about seven years old.  I try to get on the water with my kayak when I can.  Lately I’ve been dabbling in electronics again at the local makerspace.

That’s me in a nutshell.   I’m going to keep posting stuff as I find it. Here’s my CV:

    Pleased to meet you.

    I’m a 78 year old retired self employed Toolmaker from New Jersey. I look forward to your postings on Instapundit. I too shudder at what’s happening in our country and the lack of awareness of the public.We are constantly told that people like me need to be retrained….,,to do what? I think people need to be trained to do what I did. I took kids who were thrown over the side by their local schools and taught them how to make a living. I taught them how to think for themselves and develop their own “tricks of the trade.”

    I am a retired mechanical engineer living in the NW corner of CT. I worked in the aerospace industry most of my career and I know that today there is still a need for ME’s in aerospace in CT. I was going to contact you through LinkedIn but the link was broken and I could not find your profile. Contact me and I’d enjoy meeting you (I enjoy your blog) and perhaps could help with your job search. I’d even buy lunch. I’m discouraged by CT’s business climate, but there are still opportunities and in retirement I do what I can to encourage manufacturing here.

      I’d love to get in contact with new people. I didn’t realize the link was broken. I’ll fix it right now. One thing about what I’m trying to do here is to do things that help others. Yes I post weird stuff, but I also am doing the job stuff every week and the “let’s build to help people trying to make a product from a project.

    I would love to comment on the blog posts but don’t have a clue as to how to find the comment box. You know, this one, that says leave a reply? how do I find it when reading a post? I run a small manufacturing company, small, as in mom and pop type. High end architectural woodworking, we ship all over the US. We have a small machine shop as well, to support the woodworking machines. I grew up in central CT, back before RT2 turned the rural areas into suburbs of Hartford.
